And James Webb.Without a reboost Hubble's coming down between 2030 - 2040.Uncontrolled?The same as Skylab - controlled to a small degree by attitude changes that modify the atmospheric drag to some extent. Now if some kind of vehicle gets attached, then there could be real control or even a reboost.

Dec 22, 2021MAN WILL CONQUER SPACE SOON!A bold statement for the far gone, pre space-age year of 1952.Dr. Wernher von Braun and his rocket scientists were cooling their jets at what would later become White Sands Missile Range. Frustrated with developing the weapons of the cold war, they dreamed of travelling to Mars. They had worked out exactly how to do this - not as a Buck Rogers adventure, but as a detailed engineering document. All they needed was someone to bankroll the adventure.Enter Collier’s Magazine editor Cornelius Ryan. He put Wernher and his people together with concept artists such as Chesley Bonestell. He gave them a new mission: show the world how it could be done. Tell them that the Solar System is theirs if they want it.America woke up one morning in March, poured out their cornflakes and opened their mail. Before they had time to finish their orange juice, Collier’s wake-up call had expanded their horizons out beyond the asteroid belt. Space travel had suddenly become mainstream.The message was simple: “Wake up and smell the kerosene baby, the Space Age is go for launch!”Less than 20 years later, men would step out of the pages of Collier’s and walk for real upon the dusty plains of the Earth’s satellite - and it would be Wernher’s group who would help design the ships that would take them there. This is an animated tribute to that 1952 call for action.
Curious they did not make any videos showing off rockets from either Korea's nor Iran.

They all originate from documents issued by various commercial firms with projects submitted to NASA that ultimately did not materialize. When another country publishes proposed plans for rockets that did not come to fruition, he may consider them. Most other countries maintain their plans confidentially. This may explain why we have not seen any regarding the countries you inquired about.

Yet he covered TERRAN-1 that is smaller rocket than Unha-3.While Chollima-1 is heavier rocket than Kosmod-3M.Perhaps could even be medium lift vehicle by US standards.

Just pointing out curious detail about their content lacking coverage.If by any chance any of you veterans have had some prior contact with the individual, you are far more likely to get consideration.
Sep 26, 2025Aerojet 260: The Largest Solid Rocket Motor Ever TestedIn the 1960s, Aerojet, under NASA contract, developed and static-tested the Aerojet 260, the largest solid rocket motor ever built. Measuring 260 inches (6.6 meters) in diameter and over 24 meters long, it was designed as a potential booster for the Saturn V.Two test motors were loaded with 1.68 million pounds of propellant and fired vertically from an underground silo near the Florida Everglades. The motor produced over 5 million pounds of thrust and 3.47 billion pound-seconds of total impulse, with flames visible from 80 miles away during a night test.Though never flown, the 260 demonstrated the viability of massive solid rockets producing nearly 100 times the thrust of a Minuteman III second stage and remains the most powerful solid rocket motor ever tested.
Jul 22, 2022Operation Sandy was the codename for the post-World War II launch of a captured V-2 rocket from the deck of the United States Navy aircraft carrier USS Midway on September 6, 1947. It marked the first launch of a large rocket, and the only time for a V-2, from a ship at sea.Rear Admiral Daniel V. Gallery, Assistant to the Chief of Naval Operations, was an early advocate of the concept. It was he who initiated Operation Sandy.Preliminary testing was done at the White Sands Missile Range, using a simulated aircraft carrier deck. The V-2 to be used was assembled at White Sands. It was shipped across the country to the east coast and loaded aboard the Midway, then the largest carrier in the Navy and equipped with an armored flight deck. The aircraft carrier sailed to a point several hundred miles south of Bermuda for the launch.After liftoff, the V-2 tilted at an angle and subsequently broke up at an altitude of 15,000 feet (4,600 m), disappointing the distinguished witnesses."USS Midway" (https://skfb.ly/owqES) by shangus930 is licensed under Creative Commons Attribution (http://creativecommons.org/licenses/b....Satellite Launching ShipConcept artwork, depicting an Essex or Ticonderoga class aircraft carrier converted for launching space satellites into orbits not readily accessible from launch sites in the United States.The rocket shown is an "Atlas" type.Image was received by the Naval Photographic Center on 12 December 1961.
Oct 17, 2025Luna 9 was an uncrewed space mission of the Soviet Union's Luna program. On 3 February 1966, the Luna 9 spacecraft became the first spacecraft to achieve a soft landing on the Moon and return imagery from its surface.
I've never considered bouncy airbag landings to be "soft", whoever built the spacecraft and whichever celestial body they landed on. "Survivable" seems like a more accurate term to me.Also, a nit to pick with the video - the side modules were actually jettisoned 75 km above the lunar surface. The video looks substantially farther than that.

Dec 11, 2025 #rocket #spacestation #spaceplaneBuran was the Soviet Union’s reusable space shuttle orbiter, developed in the 1970s–1980s as part of the Energia–Buran program. Externally similar to the U.S. Space Shuttle, it was designed to carry crew and cargo to low Earth orbitMir-2 was a planned successor to the Soviet Mir space station. Originally conceived in the 1980s, it was intended to be a more advanced, modular orbital station with improved life-support, scientific capability, and long-duration habitation. Although Mir-2 itself was never completed as a standalone station, many of its planned modules—especially the Zvezda service module—were later incorporated into the International Space Station (ISS), becoming core elements of the ISS’s Russian Orbital Segment.
The Project Orion "battleship" was a proposed, but never built, concept for a massive, nuclear-powered space warship that emerged from the 1950s/1960s study on nuclear pulse propulsion. This military application of the Orion drive concept was presented to the U.S. Air Force and, reportedly, to President John F. Kennedy, who was so alarmed by its militaristic nature that political support for the entire project waned.
