In the United States, direct ascent proposed using the enormous Nova rocket to launch a spacecraft directly to the Moon, where it would land tail-first and then launch off the Moon back to Earth. The other options that NASA considered for the mission to the moon were Lunar Orbit Rendezvous (which was the strategy used successfully in Project Apollo) and Earth Orbit Rendezvous. The Saturn C-8 was the largest member of the Saturn series of rockets to be designed. It was a potential alternative to the Nova rocket, should NASA have chosen a direct-landing method of lunar exploration for the Apollo program. The first stage was an increased diameter version of the S-IC. The second stage was an increased diameter S-II stage. Both of these stages had eight engines, as opposed to the standard five. The third stage was a stretched S-IVB stage, which retained its original diameter and engine. When NASA announced on September 7, 1961 that the government-owned Michoud Ordnance Plant near New Orleans, LA, would be the site for fabrication and assembly of the Saturn first stages as well as larger vehicles in the Saturn program. Finalists were two government-owned plants in St. Louis and New Orleans. The height of the factory roof at Michoud meant that an 8 x F-1 engined launch vehicle (Saturn C-8, Nova class) could not be built; 4 or 5 engines would have to be the maximum. This decision ended consideration of a Nova class launch vehicle for Direct Ascent to the Moon or as heavy-lift derivatives for Earth Orbit Rendezvous. Ultimately, the Lunar Orbit Rendezvous ("LOR") concept approved in 1962 rendered the C-8 obsolete, and the smaller Saturn C-5 was developed instead under the designation "Saturn V", as the LOR spacecraft was within its payload capacity.

Has this method been proved feasible given the fuel requirements?

Music Wow

Fantastic simulation. This is the first direct ascent video I have seen. BTW the direct ascent concept explains why the engine on the service module is twice the size as was eventually needed. The contracts for the engine where signed before LOR was adopted. The engine was a varient of existing engines, so performance, cost, realiability, wieght, etc. where "knowns" so the engine was kept in the finale design. If you look at new service module engines for Constellation or Orion, they are considerably smaller. I do not know how much they have in common, but the SM engine was the starting point for the design of the OMS engines on the shuttle.

Song please
-
I've heard that even after this concept was dropped,the CSM still had a big SPS engine,although the mission needed less delta-v,wich explains why the Saturn C-5 was developed as the famous "Saturn V" and the Saturn C-8 cancelled.
-
what name of music?
-
Do an animation of the Orion Spacecraft pls?
-
3:51 Lol United States on the Descent Stage is wrote like its was on a mirror
-
Would have been fun to see n9vq
-
Aplollo + eva = this master piece.
Nice video!!! -
do you know how to control EVA in default Atlantis shuttle?
-
Plz do animations of Indian Rockets.
-
Good load, thanks! I think one the most fascinating unsung last-ditch lunar landing concepts was NASA tapping Gemini technology to land a single pilot near a pre-positioned habitat to await pickup by a follow-up Apollo mission.
-
i nearly shit my pants from that music, but otherwise good video
-
I've never really understood what an Apollo Direct Ascent/Decent is. Someone please explain to me.
-
is that kerbal space program
-
Thumbs up for the video, thumbs down for the music.
-
Why did you choose Russian sounding music for this video? It may not be Russian, but I can't help but thinking Russia.
-
We do know that NASA did do serious studies on a direct landing method for the Apollo program, but dropped the idea because it would require too big a rocket. That's why they chose the lunar orbit rendezvous method--it didn't need so big a rocket.
-
How do you see your trajectory? Honestly I wont use it because I don't like the external view, but I would like to know the key just for curiousity.
