Kind of an odd choice for him, but I do like that he also included the space telescope:

Germany's low-cost Launch Vehicle "OTRAG"

Hazegrayart
23 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.

Martin Marietta Spacemaster Shuttle

Quote
Sep 8, 2023
The Martin Marietta Spacemaster was a proposed design for the Space Shuttle.
The Spacemaster was a two-stage, reusable space transportation system.
It featured a delta-wing orbiter and a twin-fuselage booster craft.
The orbiter would sit in a recess in the booster during launch and ascent.
The liquid-propellant booster would carry the orbiter to a set altitude, then detach and be piloted back to land. After separation, the orbiter would ignite its own engines to reach orbit.
The Spacemaster was proposed in 1967. NASA did not order any Spacemasters, but it did order the Space Shuttle's external fuel tanks from Martin-Marietta. Martin Marietta is now part of Lockheed Martin

It's Tony De La Rosa, ...I don't create this stuff, I just report it.

Interesting.  I guess the two objects above the single engine are jets?

Might be a fun conversion of a shuttle model.  Not sure it needs to go all the way to Mars, but I like the Mars Vehicle.

Is this just the author's concept or is it based on a possible project.

The propulsion system had three LOX/LH2 descent engines that operated at an Isp of 459.7 sec. The engine thrust was 31.1 kN (7,000 lb). Oxygen boil-off was estimated to be at 1.2% per month and hydrogen boil-off was estimated  to be at 4.3% per month. Descent delta-v: 1,900 m/s (6,233 ft/s)

Structures

The baseline primary structural material was aluminum 2024 or similar. There were two oxidizer tanks/four fuel tanks; The landing structures made up 3.3% of the total mass to be landed.

Propulsion

There were four NTO/MMH ascent engines rated for operation at an Isp of 332.5 sec. The propulsion system provided a thrust of 11.1 kN (2,500 lb). Thrusters were initially gimballed out to avoid damaging the habitat (which could be reused on a future mission or as part of an outpost).
Ascent delta-v: 1,889 m/s (6,197 ft/s)

Structures

Aluminum 2024 or similar. There were two oxidizer tanks/two fuel tanks.

Environmental Control and Life Support System

Unconventional Liftoffs: The Hydrofoil Albatros Rocket

1974 Russian Space Shuttle Design Concept
Alexeyev Sukhoi Albatros 3 Stage Rocket System

At 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.

Von Braun's Lunar Lander





Quote

Nov 10, 2023
Wernher 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.
