In November of 2022, a Space Launch System Block I took to the night sky of Florida. But... what if a very similar vehicle flew much, much earlier? What if Orbital ATK didn't demand no less than 5 segments for Solid Rocket Boosters? What if Constellation was much less considered than another option? A proposal going by the name of... "DIRECT" Space Transportation System Derivative ____________________ Common Core Stage Every rocket in the series would utilize a Common Core Stage. This would take the External Tank from the Space Shuttle, remove the feedlines on top for the orbiter, attach a thrust structure to the bottom, remove the nose cone LOX tank, and attach a liquid oxygen tank extension and cap with a forward skirt for mounting instrument rings/payload fairings or interstages. This new core stage would be common to every flight of the vehicle. I will refer to it as the CCS. Naming The name given to each Jupiter launch vehicle had three digits; the first digit being how many stages the rocket has, the second being how many engines are on the Core Stage, and the third being how many upper stage engines it has. For example, the Jupiter-246 has 2 cryogenic stages, 4 main engines, and 6 upper stage engines. Jupiter-130 The Jupiter-130 was the first variant of the v3 family. A new thrust structure would allow for the mounting of RS-25s straight onto the CCS, which this variant would use 3 of. The instrument ring and payload fairing would be mounted straight to the top of the CCS. This medium-lift vehicle could lift about 50 tons into LEO, and was designed as a replacement for the space shuttle servicing and rotating crew on the International Space Station Freedom using CEVs. There was no ISS in my timeline. Instead, Space Station Freedom will be the "ISS" of this thread. Jupiter-246 The Jupiter-246 is very similar to the Jupiter-130, but includes a forth RS-25, and most significantly, the Jupiter Upper Stage; a very large hydrolox tank powered by the existing RL10B-2s used on the Delta IV. The instrument ring and payload fairing would sit on top as they would on the CCS of the Jupiter-130. This launch vehicle could put over 100 tons into Low Earth Orbit, which would allow for a crewed return to the Moon and eventually flights to Mars. These two rockets would be the backbone of crewed spaceflight, for decades to come; allowing for continued and much safer servicing of Freedom, a return to the Lunar surface, rides to Near Earth Objects, eventual flights to Mars, and much more... ____________________ On January 1st, 2011, a Jupiter-120 prototype roars into the morning sky of Florida.
