In the year 1960, Philip Bono, a highly specialized Space Vehicle Design Specialist affiliated with the Boeing Airplane Company, formulated a conceptualization of a pioneering manned spacecraft intended for Mars. The outward visage of this spacecraft was fashioned in a manner which exhibited similarities to the X-20A Dyna-Soar single-seat orbital glider concurrently under development at his organization on behalf of the United States Air Force. However, Bono's cerebral rendition of the Mars glider embodied noteworthy dimensional dissimilarities when compared to the Dyna-Soar -- namely, it was of an enormity that was capable of accommodating an eight-man "expeditionary force," and nearly 40 tons of supplies and equipment. The prodigious Mars glider boasted a flat-bellied physique that spanned a monumental 125 feet in length, and an impressive 95 feet across its delta wings.The Mars glider, once fully assembled and loaded with liquid hydrogen and liquid oxygen propellants, stood at a towering height of 248 feet, weighing in at an impressive 4150 tons. This colossal spacecraft was encompassed by six elongated outboard booster rockets, designed to enshroud and conceal the short booster, living module/rocket stage, and the majority of the aft portion of the glider.Bono's original vision of the Mars glider was equipped with scientific instruments that would enable it to scrutinize the Red Planet's surface and atmosphere. This glider would harness the power of its wings to generate lift, and it would have been controlled remotely from the mother ship. The spacecraft would have been launched from a mother ship which was stationed in orbit around Mars.Even though the Mars Glider concept never came to complete fruition nor was it ever launched, it nevertheless played a consequential role in the technological advancements of other Mars exploration technologies. Additionally, this epoch-making conceptualization inspired a plethora of forthcoming space exploration concepts.Epic Unease by Kevin MacLeod is licensed under a Creative Commons Attribution 4.0 license. https://creativecommons.org/licenses/...Source: http://incompetech.com/music/royalty-...Artist: http://incompetech.com/
I don't know how this guy is able to do this stuff. He's not selling ads, and clearly these videos are a lot of work. Truly impressive.
Apr 18, 2023The fundamental concept behind the STAR program was to maximize efficiency while minimizing cost. To achieve this goal, the craft was designed to be as small and inexpensive as possible, with only one crew member onboard. The crew compartment itself was unpressurized and only large enough for a seated astronaut, who would be required to remain in their spacesuit throughout the duration of the mission. Notably, the craft lacked key features such as hydraulics, an ejection seat, or even landing gear. Instead, it would utilize a parawing to glide back to Earth and touch down on land.Despite its Spartan design, the STAR was intended to function as an orbital runabout, capable of carrying out a variety of missions. The craft was eight meters in length and only a meter and a half tall at its aft end, tapering down to a fine point at its nose. To optimize its transportability, the nose was designed to fold back at a hinge four meters down from the tip of the STAR, creating a compact package just four meters in length. In terms of deployment, the Shuttle was expected to lift the STAR into orbit, potentially even multiple at a time, and deploy them from its cargo bay. Once in space, the STAR would set off on its designated missions, either returning to the Shuttle or making its own way back to Earth. If the STAR needed to reach higher altitudes beyond its on-board propellant capacity (which was estimated to be around 1650 kilometers), a truncated Centaur stage equipped with a single RD-10 engine - known as the Centaur-SP - could be attached to the STAR for increased thrust. This configuration would fit into the Shuttle's cargo bay, allowing for transport to geosynchronous orbit and beyond.

Remember reading about something like this in a Sci-fi magazine during the 80s. Basically adapting a slight scaled up ICBM reentry vehicle for nukes to be a crew capable reentry vehicle. The flight characteristics of the reentry vehicle is well understood and tested.IMO, the vehicle could be use as a supplemental lifeboat for a space station in LEO. Of course you will need some kind of EVA suits for the whole crew. Which means you could use this vehicle as lifeboats on the Shuttle.The use of the vehicle docked to the cut down Centaur is more interesting. In theory you could use it to transfer between the Shuttle in LEO and an orbital platform in a higher orbit. It will be cheap since the flight controls are presumably in the Centaur and no other modifications is required other than more consumables for the single crew. Think there is enough delta-V left in the Centaur for a reentry burn after reaching the higher orbital platform.Of course the vehicle concept is a bit crazy.

An-325: The Giant Carrier for Britain's Interim HOTOL SpaceplaneHazegrayart18 May 2023The HOTOL (Horizontal Take-Off and Landing) project aimed to develop a British unmanned re-usable spacecraft similar to the American Space Shuttle and Soviet Buran. It intended to be a single-stage-to-orbit (SSTO) craft capable of operating from runways. HOTOL planned to use a unique propulsion system that acted as both an airbreathing jet engine and a rocket engine.Alan Bond, a rocketry engineer, researched an airbreathing rocket engine concept in 1982. His idea addressed the challenge of carrying propellant onboard SSTO vehicles by using external atmospheric oxygen, combined with liquid hydrogen, for thrust until reaching Mach 5.5. Afterward, it would switch to conventional rocket mode using liquid oxygen.In 1985, Rolls Royce acquired Bond's engine rights and collaborated with British Aerospace (BAe) on the HOTOL project. However, difficulties arose due to the mismatch between the center of pressure and gravity during flight. The British government withdrew support in 1988, leading to the project's cancellation.Nonetheless, in 1990, the project experienced a resurgence when BAe approached the Soviet Union with a proposal to launch a derivative of HOTOL by piggybacking aboard the massive Antonov An-225 transport aircraft. This derivative, known as the Interim HOTOL, would forego the complex RB545 engines in favor of conventional rockets supplied by Russia. The Interim HOTOL would be mounted atop the An-225, originally designed to carry the Buran space shuttle, and ascend to an altitude of approximately 29,500 ft (9,000 m). Once released, the Interim HOTOL would ignite its rocket engines and be propelled into orbit while carrying a payload of 4.5 tons.Antonov also explored the development of an enhanced derivative of the An-225, called the An-325, equipped with two additional engines to accommodate a larger payload and potentially launch a larger version of HOTOL or a Russian vehicle. Unfortunately, the Interim HOTOL fared no better than its predecessor and was discontinued in 1992 due to a lack of interest from both the European Space Agency (ESA) and the UK government.The HOTOL project showcased ambition and innovation but faced challenges in achieving its goals. Nonetheless, it contributed to subsequent developments such as Skylon, as the quest for efficient and cost-effective space transportation continues.
Mar 20, 2021HOTOL was a 1980s British project to build a totally reusable Space Shuttle. The project was cancelled and as it existed in the pre-internet age it's hard to find information about it.Whilst I was making my Spaceplanes video I came across a HOTOL brochure from 1985. I thought I would go through it and give an overview of this extremely interesting project.

Apr 16, 2018The only orbital launch of a Buran-class orbiter occurred at 03:00:02 UTC on 15 November 1988 from Baikonur Cosmodrome launch pad 110/37.[3][5] Buran was lifted into space, on an unmanned mission, by the specially designed Energia rocket. The automated launch sequence was performed as specified, and the Energia rocket lifted the vehicle into a temporary orbit before the orbiter separated as programmed. After boosting itself to a higher orbit and completing two orbits around the Earth, the ODU engines fired automatically to begin the descent into the atmosphere, return to the launch site, and horizontal landing on a runway.
Full Version: Feb 3, 2021, Shorten Version June 2, 2023Project Orion was a study of a starship intended to be directly propelled by a series of explosions of atomic bombs behind the craft (nuclear pulse propulsion)The project was eventually abandoned for multiple reasons such as the Partial Test Ban Treaty which banned nuclear explosions in space as well as concerns over nuclear fallout.The biggest design was the "Super" Orion design; at 8 million tons, 7250000000 Kilograms it could easily be a city. One design proposed by Freeman Dyson for the "Super Orion" called for the pusher plate to be composed primarily of uranium or a transuranic element so that upon reaching a nearby star system the plate could be converted to nuclear fuel.
Soviet Union's other Moon Rocket: UR-700A4 Jun 2023The regular UR-700 had a payload capacity of 151 tons to Earth orbit, surpassing both the N1 (97 tons) and the American Saturn-5 (127 tons). Additionally, Chelomei's engineers developed a larger follow-on version called Skhema "A" (Configuration "A"), which incorporated nuclear engines. This configuration featured a solid-core nuclear reactor and increased the payload capacity to as much as 250 tons into Earth orbit.The first two stages of the UR-700 with the "A" variant propulsion were similar to the regular UR-700. The six boosters in the first stage fed their own engines and simultaneously refueled the three boosters of the second stage. This ensured that the second stage had full tanks when it took over the powered ascent after the separation of the first stage.The "atomic" version of the UR-700 included third and fourth stages developed from scratch, equipped with RO-31 nuclear engines (also known as RD-0411). These engines burned cryogenic liquid hydrogen or liquid methane and produced a thrust of 40 tons. The third stage featured seven RO-31 engines, while the fourth stage had three. The third stage could be responsible for sending a spacecraft on an escape trajectory from Earth orbit, while the fourth stage could perform a braking maneuver near the Moon or Mars.
Dec 2, 2022The LK was a lunar module (lunar lander designed for human spaceflight) developed in the 1960s as a part of several Soviet crewed lunar programs. Its role was analogous to the American Apollo Lunar Module (LM). Three LK modules, of the T2K variant, were flown without crew in Earth orbit, but no LK ever reached the Moon. The development of the N1 launch vehicle required for the lunar flight suffered setbacks (including several launch failures), and the first Moon landings were achieved by US astronauts on Apollo 11. As a result, having lost the Space Race, both the N1 and the LK programs were cancelled without any further development.Sergei Korolev, the lead Soviet rocket engineer and spacecraft designer during the 1950s and 1960s, planned to adopt the same lunar orbit rendezvous concept as seen in the Apollo program. The lunar expedition spacecraft L3 was to consist of a Soyuz 7K-L3 Command Ship (a variant of the Soyuz) and an LK Lander. L3 would carry a two-man crew atop a single three-stage superheavy N-1 booster. A fourth stage, the Blok G, would push the L3 (LOK+LK) toward the Moon, with the Blok D as a fifth stage.LK compared to the Apollo Lunar ModuleBecause the payload capacity of the N1 rocket was only 95 tons to LEO, versus the Saturn V's 140 tons to LEO, the LK was created to be less bulky than the Apollo Lunar Module (LM):It had a different landing profileIt was lighter at only one-third the mass of the LMInitially, the LK was to have carried a single cosmonaut. A later variant would have a two-man crew; the LM took twoIt had no docking tunnel like the LM's; the cosmonaut would spacewalk from the LOK (Soyuz 7K-L3) to the LK and back.LK Lunar Lander, Soyuz-Lok,N1 Rocket service tower,3rd Stage n1 Models from Sketchfab user "Soviet Model Magic"

Think the lit up areas of the Moon in the future will be much dimmer than in Hazegrayart's video. The sensible thing to do is go underground for radiation protection and thermal stability. So Lunar top side infrastructure will likely be minimal.

Jul 25, 2018Project Orion was a Supper Heavy Lift Spacecraft intended to be directly propelled by a series of explosions of atomic bombs behind the craft. This is a 10 Meter version with Eight astronauts, with around 100 tons of equipment and supplies, which could have made a round trip to Mars in 125 days. The biggest design is the "super" Orion design; at 8 million tonnes, it could easily be a city.And yes, there is no sound in space.
July 10, 2023The Sea Dragon rocket was a proposed heavy-lift launch vehicle designed by Robert Truax in the 1960s. While it never flew, the Sea Dragon rocket remains one of the largest and most ambitious launch vehicle concepts ever conceived.Here are some key details about the Sea Dragon rocket:Size and Payload: The Sea Dragon rocket was designed to be enormous, standing at a height of about 150 meters (500 feet) and having a diameter of 23 meters (76 feet). It was intended to launch payloads of up to 550 metric tons (1.2 million pounds) into low Earth orbit (LEO), which is significantly more than any rocket that has ever been successfully launched.Unique Design: The Sea Dragon rocket was distinctive due to its unconventional construction method. It was planned to be built in two stages. The first stage would be constructed underwater and integrated with the launch platform. Once completed, the entire structure would be floated to the launch site, and the second stage would be attached on top.Propulsion: The Sea Dragon rocket would have used a combination of liquid oxygen (LOX) and kerosene (RP-1) as propellants. The first stage was planned to use multiple engines, possibly derived from the F-1 engines used on the Saturn V rocket, while the second stage would have used a single large engine.Purpose and Potential: The Sea Dragon rocket was intended to significantly reduce the cost of accessing space by leveraging the economy of scale. By launching massive payloads, it aimed to make space transportation more cost-effective. It was envisioned to be used for various purposes, including the launch of space station modules, lunar missions, and even manned missions to Mars.Despite the impressive design, the Sea Dragon rocket never progressed beyond the conceptual stage. It faces numerous technical and logistical challenges, including the difficulty of transporting such a large vehicle by sea, the absence of appropriate launch facilities, and the uncertainties associated with its construction and operation.While the Sea Dragon rocket remains an intriguing concept, it serves as a reminder of the engineering complexities involved in building and launching extremely large launch vehicles.
The Comet Rocket is a proposed super heavy-lift launch vehicle (HLLV) designed for NASA's First Lunar Outpost Program (FLO) from a 1992-1993 Space Exploration Initiative. It was a Saturn V-derived launch vehicle with modernized engines, stretched fuel tanks, and strap-on boosters

I consider the DARPA's STAR to be less of an obstruction to the sub's maneuverability than a carrying a DSRV (deep-submergence rescue vehicle) behind the sail on the top deck of the U.S.S. Jimmy Carter.AIUI the when a ballistic missile is ejected underwater from a submarine silo it is exposed to sea water. AFAIK almost all strategic ballistic missiles deployed aboard a boomer sub can only ignites their motor after clearing the ocean surface and the water plume from the ejection.The orbit of the targeted satellite is known not long after it's launch. Presumably it will be treated as any other targets on the sub's target list with updated orbital data when the launch order is transmitted to the sub. Think the Space Cruiser have the same mid-course guidance package as the reentry vehicles with the nukes with the Astronaut as terminal guidance.The Astronaut is deploying a magnetic shaped-charged demolition charge likely with a adhesive coating on the business end.As stated up thread the concept for the DARPA's STAR is bit crazy. Why Astronaut is required for the mission concept is that robotics and avionics hadn't advanced enough to replaced the Astronaut at the time the concept was conceived.
<snip>Now my own crazy idea - if that vehicle could withstand re-entry nose-first, it should have been very much stronger than any on-orbit spacecraft without re-entry capability. In that case, it didn't actually need the astronaut setting explosives. Just a low-speed bump with that nose at any random point on the target would have probably been enough to disable or destroy it.
ESA's Airbus Reusable Rocket: The AdelineHazegrayart4 Aug 2023Introducing Adeline - A Revolutionary Leap in Reusable RocketryImagine a rocket that not only soars into the sky with a thunderous roar but elegantly glides back to Earth, ready for another thrilling journey among the stars. Enter Adeline (Advanced Expendable Launcher with Innovative engine Economy), a groundbreaking concept brought to life by the brilliant minds at Airbus Defence and Space. This audacious vision aims to redefine the boundaries of space travel by harnessing the power of drone technology to achieve horizontal runway landings - an awe-inspiring spectacle that is sure to leave space enthusiasts in absolute awe!At the core of this visionary concept lies a rocket booster like no other. Equipped with propeller engines and cutting-edge avionics, it promises to be more than just a disposable first-stage component. Adeline's true genius lies in its ability to gracefully touch down on a runway, post-launch, only to be lovingly refurbished and sent off on yet another exhilarating adventure.As the fiery launch propels the stage forward, the engine module knows its fate and bravely bids farewell, preparing for the daring descent. Here's where Adeline unleashes its wings - tiny, yet potent winglets that nimbly guide the booster towards its coveted runway destination. Thrilling, isn't it?As the runway looms closer, the tension builds; this is the moment when the landing gear springs into action, providing the stability needed for a picture-perfect horizontal landing. To add a touch of ingenuity, two small pusher configuration propellers join the ensemble, lending that extra oomph to the landing. Talk about elegance and power wrapped into one!Now, let's talk economics. Adeline has an ace up its sleeve. By reusing a whopping 80% of the stage's economic value - encompassing the engine, avionics, and propulsion bay - it stands as a beacon of sustainability and cost-effectiveness. SpaceX, though impressive with its vertical landing feats, does not escape the taxing stresses their booster engines endure during deceleration. Adeline, on the other hand, gracefully glides and only requires a modest 2,000 kg of fuel for a geostationary flight back to the ground. Compare that to the estimated 35,000 kg needed for a SpaceX booster's return to the launch site. Mind-blowing, right?Now, fuel might be a mere fraction of the overall launch cost, but it's a game-changer for Adeline. The beauty lies in the reduction of launch costs, ranging from 21-40%. However, the catch lies in the payload capacity, which could diminish from 8,300 kg to 5,500 kg with this approach. But fret not, as the true cost advantage emerges when ferrying payloads much lower than the rocket's lift potential. Unleash the unused lift capacity, and voila! Extra fuel to recycle the rocket and unlock new realms of possibilities.You might wonder where this marvel will find its niche. Fear not, for the future is ripe with potential. Adeline could seamlessly integrate into the evolution of Ariane 6 or any liquid-fueled rocket. Talk about versatility!Embarking on this interstellar journey was no easy feat. Airbus commenced this ambitious program in 2010, investing a staggering €15 million by May 2015 to refine the art of reusability. Scale models took flight, fueling the dream of a reusable rocket future. As Ariane 6 takes center stage in Airbus's development priorities, Adeline awaits her turn to shine.Of course, with every bold venture, there are skeptics lurking in the shadows. In 2018, an official from the CNES launcher directorate expressed doubts about the concept's financial viability. But remember, history has shown that audacious visions often take time to win over skeptics and blaze new trails.

Germany's low-cost Launch Vehicle "OTRAG"Hazegrayart23 Aug 2023"Orbital Transport und Raketen AG," which translates to "Orbital Transport and Rockets Inc." in English. OTRAG was a German aerospace company founded by Lutz Kayser in the 1970s. The company aimed to develop low-cost launch vehicles for sending payloads into space.OTRAG gained attention for its innovative approach to rocket design, focusing on modular construction and the use of multiple small rocket engines. This was intended to reduce costs and increase flexibility. The company conducted some test launches in the 1970s and 1980s in various locations, including Zaire (now the Democratic Republic of Congo), where they had agreements to test and launch their rockets.However, OTRAG faced political and regulatory challenges, and its activities raised concerns about potential military applications. As a result, the project was met with international scrutiny, and it eventually faced obstacles that led to its decline. The company's work was largely put on hold, and the ambitious plans to revolutionize space transportation were never fully realized."Space Cargo Transporter" (https://skfb.ly/oFOAQ) by kunyong_Chen is licensed under Creative Commons Attribution (http://creativecommons.org/licenses/b....
Sep 8, 2023The Martin Marietta Spacemaster was a proposed design for the Space Shuttle. The Spacemaster was a two-stage, reusable space transportation system.

Unconventional Liftoffs: The Hydrofoil Albatros Rocket1974 Russian Space Shuttle Design ConceptAlexeyev Sukhoi Albatros 3 Stage Rocket SystemAt its core, the vehicle was conceptualized as a multi-stage system, with the initial stage featuring a hydrofoil weighing approximately 1800 tons and stretching 70 meters in length. This hydrofoil, designed by Alexeyev, served as a precursor to a full-fledged ekranoplan. Its purpose was akin to the Space Shuttle’s external fuel tank, carrying a substantial payload of 200 tons of Liquid Oxygen (LOX) and Liquid Hydrogen (LH2). These propellants were intended to fuel the motors of the second stage.Mounted atop the hydrofoil, the second stage, estimated at 210 tons, utilized the LOX and LH2 from the first stage to accelerate the entire assembly to a remarkable speed of 180 km/h over a span of 110 seconds. This acceleration occurred along the surface of the Caspian Sea, or alternatively, the Aral or Lake Baikal, effectively utilizing the vast water bodies as makeshift runways. After reaching the desired speed, the second stage detached from the hydrofoil and initiated its own propulsion system, lifting itself off the now-empty barge.This second stage was an innovative creation from Sukhoi, designed as a high-speed reusable winged rocket plane/booster. Its primary objective was to elevate the third stage—an actual spaceplane, also crafted by Sukhoi—to a high altitude. The spaceplane, a pivotal component of the system, was equipped to propel itself into orbit while the booster, having fulfilled its purpose, coasted back to Earth. While details about the piloted nature of the booster remain uncertain, given Sukhoi’s background, it is plausible that it might have been manned.The final stage of this remarkable vehicle was a tail-less rocket plane, boasting a mass of about 80 tons and spanning 40 meters in length. This design made it comparable to the American orbiter. Despite its similarity in appearance to certain iterations of the Hermes shuttle or the later Russian/European Kliper, it stood out due to its payload capacity of 30 tons to Low Earth Orbit (LEO) and its crew of two. Technically, this stage was a marvel, incorporating advanced engineering concepts to achieve its objectives.Sources:https://falsesteps.wordpress.com/2016/07/14/sidebar-alexeyevsukhoi-albatros/http://www.astronautix.com/a/albatros.html."Ship Lorina" (https://skfb.ly/oJXpU) by mamont nikita is licensed under Creative Commons Attribution (http://creativecommons.org/licenses/b....Song: Dryskill & Max Brhon - War Machine [NCS Release] Music provided by NoCopyrightSounds Free Download/Stream: http://ncs.io/WarMachine
Nov 10, 2023Wernher Von Braun, the visionary space pioneer, boldly prognosticated that a cadre of erudite scientists would grace the lunar surface with their presence, accomplishing this audacious feat by the year 1977. Picture this: two incarnations of the spacecraft, akin to lunar taxis, designated as the "passenger" versions, gallantly transporting a grand total of 50 scientists and adept technicians. Meanwhile, the intrepid "cargo" version embarked on a solitary sojourn to the Moon, laden with provisions deemed essential for the sustenance of the aforementioned 50 gentlemen during their anticipated six-week sojourn on Earth's proximate celestial companion. Notably, the nomenclature of the series hinted at a predominantly male cast.Consider the colossal stature of these celestial vessels, towering at an impressive 160 feet—a height analogous to the entirety of the Space Shuttle stack. Dr. von Braun's foresight manifested in the selection of rocket propellants—nitric acid and hydrazine—a choice that, remarkably, aligns with the contemporary trifecta of popular rocket fuel combinations (the others being LOX/LH2 and LOX/Kerosene). However, his less prescient inclinations manifested in the utilization of a mercury-vapor powered turbine, harnessing the Sun's parabolically concentrated light to evaporate liquid mercury and generate a formidable 35 kilowatts. Despite being the avant-garde darling in 1952, these turbines fell out of favor shortly thereafter, with no known instances of deployment in outer space.The spacecraft's genesis unfolded over an extended eight-month period, meticulously assembling itself in proximity to a space station nestled in a 1730-km-altitude, 2-hour circular orbit. However, this orbit's charm waned upon the discovery that it meandered within the unexpected embrace of the Van Allen radiation belts, rendering it unsuitable for the manned spacecraft's traverse.Upon lunar arrival, the intrepid astronauts,, embarked upon the ambitious endeavor of erecting a lunar base. Von Braun, exuding confidence, foretold that this lunar foothold would inevitably pave the way for humanity's foray into the Martian frontier, an assertion that hinted at a cosmic odyssey poised to unfold in the not-too-distant future.

The two-stage design allowed for versatility in missions, either for reaching orbit or suborbital flights, demonstrating the adaptability of its components for various space missions.
Nov 24, 2023DARPA studied modifying the current external tank design to be able to carry low-density payloads in a 25 or 35 ft (7.6 or 10.6 m) diameter fairing where the oxygen tank was currently. The Shuttle on average would only fly 66% of its payload capability but at nearly 100% of its payload volume. The external tank payload fairing would solve this problem. The oxygen tank would be redesigned as a cylindrical tank rather than conical and the clamshell payload fairing would be mounted directly on it. In this configuration, the orbiter would launch without any payload. These studies were eventually abandoned due to the fact that the new aerodynamic profile would make a Return to Launch Site (RTLS) maneuver impossible.
Kliper Spaceplane: ESA-Russia Collaboration that never MaterializedHazegrayart5 Dec 2023The Kliper spaceplane was a proposed Russian reusable spacecraft intended for crewed missions to low Earth orbit (LEO), the Moon, and potentially Mars. Developed by RSC Energia, it aimed to be a successor to the Soyuz spacecraft and capable of transporting both crew and cargo to space.Key features and concepts associated with the Kliper spaceplane included:Reusability: Designed to be partially reusable, enabling multiple flights after refurbishment similar to the Space Shuttle program.Crew Capacity: Planned to accommodate up to six cosmonauts for missions to the International Space Station (ISS) or other orbital missions.Launch Vehicle: Intended to be launched atop a variety of rockets, including the Soyuz-2 and Angara rockets, depending on mission requirements.Mission Capabilities: Envisioned for missions to the ISS, lunar expeditions, and potentially Mars missions, providing a versatile platform for various space exploration endeavors.Landing System: Planned to return to Earth autonomously, with the ability to land on conventional runways, similar to the Space Shuttle, reducing the reliance on ocean landings.The Kliper project generated significant interest and anticipation, but it faced funding challenges and shifts in priorities within the Russian space program. Ultimately, the project was shelved in the mid-2000s in favor of other initiatives, such as the continued use and development of Soyuz spacecraft and modules for the ISS missions.Despite its discontinuation, the Kliper concept and its design elements have contributed to discussions and ideas surrounding future crewed spaceflight and reusable spacecraft within the Russian space industry.The Soyuz-3 concept, as described from the information available, seems to incorporate several key technical details:First Stage:Comprised of four conical strap-on boosters.Equipped with a modified version of the RD-120 engine, borrowed from the operational Zenit-2 rocket.Second Stage (Core/Sustainer Stage):Borrowed body dimensions from the Avrora project.Top section had a cylindrical shape with a constant diameter (different from previous conical shapes).Carried the NK-33 engine, inherited from the ill-fated N1 rocket of the 1960s Moon Race.The scale model lacked the RD-110P steering engine on the 2nd stage.Third Stage:Developed from scratch.Equipped with four RD-0146E engines.Utilized cryogenically cooled liquid oxygen and liquid hydrogen as propellants.The basic concept of the engine was also intended for upper stages of the Proton-M and Angara launch vehicles.These specifications indicate a mix of heritage technology and new developments, combining engines from previous projects like the N1 and Zenit rockets with new designs for the third stage. The use of cryogenic propellants in the third stage suggests a focus on achieving higher performance. (Клипер, English: Clipper) was an early-2000s proposed partially-reusable crewed spacecraft concept by RSC Energia. Due to lack of funding from the ESA and RSA, the project was indefinitely postponed by 2006.Designed primarily to replace the Soyuz spacecraft, Kliper was proposed in two versions: as a pure lifting body design and as spaceplane with small wings. In either case, the craft would have been able to glide into the atmosphere at an angle that produces much less stress on the human occupants than the current Soyuz. Kliper was intended to be designed to be able to carry up to six people and to perform ferry services between Earth and the International Space Station.Presumably Soyouz 2-3 would have been able to launch the Kliper without wings and without the service module (working with the module Parom), whereas Soyouz 3 would have been used for the winged and autonomous heavier version (capable of docking to the station by its own).Royalty Free Music from Tunetank.comTrack: The Time by MusicAreahttps://tunetank.com/track/3935-the-t..."Soyuz TMA" (https://skfb.ly/oupxS) by TwilightSparkleX is licensed under Creative Commons Attribution (http://creativecommons.org/licenses/b....
It's neat to see him do that one. Kliper was interesting when it was first proposed, but then it joined a long list of Russian Soyuz replacements that never happened.Has he done Hermes yet? That seems like a rather obvious one.
No Hermes so far, unfortunately. Agree it would make sense.
SpaceX STARSHIP, Blue Origin NEW GLENN, ULA VULCAN CENTAUR, Relativity Space TERRAN R, Landspace ZHUQUE-2, Rocket Lab NEUTRON, Relativity Space TERRAN 1,ESA Ariane Group THEMIS, Stoke Space The possibilities of employing methane as a fuel for rockets have the potential to radically overhaul the space industry in multifarious ways. Primarily, as aforementioned, methane embodies a more ecologically friendly fuel source than traditional rocket fuels. If implemented, the utilization of methane-powered rockets has the capability of reducing the carbon footprint of space exploration, which has heretofore been an industry notorious for its pollutant output. Secondly, methane has greater accessibility than certain other rocket fuels, such as liquid hydrogen. Methane is derived from a plethora of sources, ranging from natural gas to renewable sources such as biomass and waste. This denotes that the production and distribution of methane as a rocket fuel can be more stable and less dependent on particular geographic locations. Thirdly, the potential for methane-powered rockets to be more efficient and cost-effective than traditional rockets is a plausible reality. Due to its increased density relative to hydrogen, methane can be stored in smaller tanks and requires less insulation to maintain a suitable temperature. This can lead to decreased launch costs and facilitate the execution of more frequent space missions. Finally, the possibilities of methane-powered rockets afford the potential for lengthier and more ambitious space missions, notably to destinations like Mars. Methane can be synthesized on Mars utilizing the planet's abundant carbon dioxide atmosphere and water ice. Consequently, methane-powered rockets could potentially refuel and return to Earth or proceed to other destinations in the solar system. Taken together, the implementation of methane as a rocket fuel holds the promise of a revolutionary transformation within the space industry. It can potentially make space exploration more sustainable, cost-effective, and ambitious than ever before.
The Russian Winged Orbital Launch Vehicle, a visionary project by the Soviet Air Force, aimed for a horizontal takeoff/horizontal landing, reusable space launch system akin to conventional aircraft. Developed by Mikoyan from 1960 to 1976, it featured a reusable hypersonic air-breathing booster, two expendable rocket stages, and the Spiral manned spaceplane. Hindered by inadequate government funding, it only reached subscale flight tests by the mid-1970s. Development ceased in 1976, giving way to the Buran, a Soviet version of the U.S. space shuttle. However, the concept saw a resurgence in the 1980s as the MAKS spaceplane, embodying technological evolution and human perseverance in aerospace innovation.
Jan 31, 2024In July 1960, Mikhail Yangel's OKB-586 design bureau, based in the city of Dnepropetrovsk Ukraine proposed the development of a rocket capable of carrying 40 tons into low Earth orbit, filling the gap between Korolev's N-1 (75 tons) and Chelomei's UR-500 (20 tons). Named R-56 with industrial designation 8K68, its preliminary design saw the liftoff weight increase from 1,200 to 1,400 tons.On May 22, 1963, the Central Committee of the Communist Party and the Soviet Ministers of the USSR authorized the experimental project (EP) for the R-56 rocket. Its potential applications included delivering geostationary satellites, lunar and planetary probes, manned circumlunar expeditions, and lunar surface supply missions.During conceptual design, KB Yuzhnoe explored three configurations for the R-56:Four modules: Each module with a 3.8-meter diameter for rail transportation.Seven-module: Each module with a 3-meter diameter, similar to the R-36 missile.One-module: Booster stages with a 6.5-meter diameter, necessitating waterway transportation.Despite the need for significant upgrades to production facilities and new means of stage delivery from the manufacturer to launch sites in Dnepropetrovsk, KB Yuzhnoe chose the one-module configuration.

ReNova SSTO Rocket Concept Developed by Martin3 Mar 2024The rocket engines are arranged in a ring around the major diameter of a STO.The hydrogen tanks form what is , in effect, a a large plug, with a toroidal oxygen tank mounted forward.. The rockets are enclosed in an air duct equipped with adjustable inlets. A jettisonable shroud extends the mixing area down stream of the rockets. The conical payload fairing serves as an inlet spike during accent through the atmosphere. The air enter through the inlet, mixes with the rocket exhaust, is heated and expands past the plug-shaped aft body, thus contributing additional thrust. The mixing shroud is jettisoned and the inlets are closed after leaving the atmosphere
Aug 30, 2022Gateway is a critical part of NASA’s deep space exploration plans, along with the Space Launch System (SLS) rocket, Orion spacecraft and human landing system. As astronauts prepare for missions to the lunar surface, they will need deliveries of critical pressurized and unpressurized cargo, science experience and supplies, such as sample collection materials and other items. In March 2020, NASA awarded SpaceX as the first U.S. commercial provider under the Gateway Logistics Services contract to deliver cargo and other supplies to the lunar outpost on the SpaceX Dragon XL logistics module.The agency’s powerful Space Launch System rocket will launch four astronauts aboard the Orion spacecraft for their multi-day journey to lunar orbit. There, two crew members will transfer to the SpaceX human landing system (HLS) for the final leg of their journey to the surface of the Moon. After approximately a week exploring the surface, they will board the lander for their short trip back to orbit where they will return to Orion and their colleagues before heading back to Earth.NASA’s Artemis program will land astronauts on the Moon and reveal new knowledge about the Moon, Earth and our origins in the solar system.

Apr 2, 2024The Energia Vulkan design was the largest of the Energia concepts with eight Zenit booster rockets and an Energia-M core as the upper stage, the Vulkan (which shared the name with another Soviet heavy lift rocket that was cancelled years earlier) configuration was initially projected to launch up to 200 metric tonnes into 200 km orbit with inclination 50.7°The development of the Vulkan and the refurbishment of Universal Test Stand and Launch Pad at site 250 for its launches was in progress between 1990–1993 and abandoned soon after due to a lack of funds and the collapse of the Soviet Union.
Apr 10, 2024The Saturn MLV was a proposed concept family of rockets, intended as a follow-on to the Saturn V. MLV stands for "Modified Launch Vehicle".Vehicle configurations representative of several alternative uprating methods were specified by the Marshall Space Flight Center for initial studies.Proposed modificationsThrust uprating and modifying of the five F-1 rocket engines used in the first S-IC stage, and corresponding increases in propellant tank capacities.Addition of a sixth F-1 engine in the S-IC stage, as an alternative to engine uprating, plus increased propellant capacities.Use of UA1205 solid rocket boosters derived from the Titan IIIC vehicle.Additional J-2 engines in the S-II stage, ~131 s increased upper stage propellant capacities.Improved or advanced upper stage engines, such as the HG-3, plus increased propellant capacities.The baseline Saturn MLV would incorporate these changes from the Saturn V vehicle. The Saturn IC first stage would have been stretched 240 inches (610 cm) with 2,500,000 kg (5,600,000 lb) of propellant and five new F-1A engines; the S-II second stage would have been stretched 41 inches (100 cm) with 450,000 kg (1,000,000 lb) of propellant and five J-2 engines; the S-IVB third stage would have been strengthened, but with a standard 100,000 kg (230,000 lb) of propellant, and one J-2 engine. Nuclear propulsion in the third stage and toroidal J-2 engines in the second and third stages were also investigated.
Would it still fit the VAB?
Quote from: Kansan52 on 04/10/2024 05:44 pmWould it still fit the VAB?The one in the video would have. It's some 24 feet taller than the Saturn V, so 387 feet tall. The VAB doors are 456 feet tall, having been sized to accommodate the Nova.

Feb 10, 2020A 1968 NASA-sponsored study of a large multipurpose launch conceptA potential application of this launch vehicle concept is for launching future manned interplanetary, extended lunar, and large space station payloads. For many missions, the payload versatility of the launch vehicle system could be used to orbit the total payload requirements in a single launch, obviating the need for orbital assembly. Previous mission analysis information indicated that a payload capability from one to four million pounds to low earth orbit would adequately cover the range of these mission requirementsThe concept is a "building-block'' vehicle system that features a main stage capable of single- stage-to-orbit operation and add-on stages, either boost assist or upper stages, that afford a broad range of payload capability.Ten 372-inch solid motors would have resulted in a payload up to 4.2 million pounds REFERENCESCONCEPT FOR A LARGE MULTIPURPOSE LAUNCH VEHICLE By Edward W.

Mar 22, 2021Source:SRB-X SHUTTLE DERIVED VEHICLE ANALYSISSOLID BOOSTER UNMANNED LAUNCH VEHICLECONCEPT DEFINITION STUDYVolume IITECHNICAL REPORTDISO-27351-2February 1983Contract NASS-34722Submitted to The National Aeronautics and Space AdministrationGeorge. C. Marshall Space Flight Center byBoeing Aerospace CompanySeattle, Washington 98124The SRB-X study was initiated by NASA in response to preliminary investigationsthat suggested future launch requirements could best be satisfied by a mixed fleet ofmanned and unmanned launch vehicles. Manned requirements are expected to be met bythe space shuttle, at least to the turn of the century, but requirements for the unmannedvehicle are not specific at this time. The following, however, represent potential uses orbenefits that indicate, when viewed collectively, that an unmanned vehicle could be avaluable addition to the space transportation system (STS). Such a vehicle coulda. Provide shuttle contingency or backup in the event of an out-of-service orbiter, amajor accident, or failure to achieve acceptable turnaround time.b. Deliver payloads that exceed the size and mass constraints imposed by theshuttle.C. Free the shuttle for missions unique to its capabilities, thus extending the life ofthe orbiter fleet.d. Supplement the shuttle flight rate in the event launch needs increase appreciably.e. Deliver cargo considered hazardous or presenting additional risk to the shuttle.The SRB-X is one of several shuttle-derived vehicle (SDV) concepts being considered for the unmanned launch vehicle role. The distinguishing feature of the concept isthat, to the greatest extent possible, primary propulsion would use the space shuttle'ssolid rocket motors (SRM), boosters, or derivatives rather than the LO2/LH2 main propulsion system.
McDonnell Douglas X-33 SSTO Reusable Launch Vehicle11 May 2024Single-Stage-To-Orbit (SSTO) Reusable Launch Vehicle (RLV). McDonnell Douglas submitted a vertical landing configuration design which used liquid oxygen/hydrogen engines. NASA considered design submissions from Rockwell, Lockheed Martin, and McDonnell Douglas. NASA selected Lockheed Martin’s X-33 design on 2 July 1996. The RLV technology program was a cooperative agreement between NASA and industry. The goal of the RLV technology program was to produce significant reductions in the cost of access to space, and to promote the creation and delivery of new space services and other activities that would have improve U.S. economic competitiveness.
May 28, 2024At the 2010 AIAA Joint Propulsion conference, SpaceX presented potential designs for future heavy and super-heavy lift vehicles.Falcon XX is a single core launch vehicle with a diameter of 10 meters and an estimated length of about 100 meters using six Merlin 2 engines operating at the 100% thrust setting on its first stage creating a liftoff thrust of 45,360 Kilonewtons (4,625 metric tons).

You are certainly right - but the sheer attractivity of it was the elimination of the mate/demate device... just roll the orbiter under the central wing, attach, and fly away.

Attach to what? Did the Shuttle have hard-points on the top that it could be suspended by?[Edit: In the video, the two designs seemed to use completely different attachment points on the Orbiter. But I don't know how much of that is artistic guesswork.]

I wouldn't presume that the as-built points were rated for flight transport, but they would have been if either of these carrier schemes had gone forward.
There was a way to remove/lift a shuttle for mating/de-mating with the 747 SCA using two large cranes.
Jun 27, 2024The Rockwell C-1057, born during Phase B studies, aimed to shorten the Shuttle Orbiter without losing payload space. Engineer Harry Scott proposed an unconventional solution: turning the cargo bay sideways. The resulting "Breadbox" was short, squat, and surprisingly aerodynamically sound. However, integrating it with the ET and SRBs remained a mystery, contributing to its demise as a concept.
