Author	Topic: Recovery and reuse of Saturn V's first stage
Robert Pearlman Editor Posts: 26175 From: Houston, TX Registered: Nov 1999	posted 01-28-2008 11:10 AM The Space Review: Monster chopper Back in 1965 the company made a proposal so bold that it bordered on insane: a giant helicopter with a rotor diameter bigger than the length of a football field, capable not merely of transporting a Saturn 5 first stage, but of actually catching it in midair as it fell on a parachute. There were other proposed means for the recovery of the SI-C including a winged flyback version and a parachute-assisted approach outlined in an 18-page booklet prepared by Boeing:

As I understand it, the factors against such a proposal was not only the limited number of Saturn flights, but also the increased deadweight at having to carry recovery systems (although, admittedly, I don't recall how much weight a Saturn V can carry vs how much it actually carried for a lunar mission, and whether or not it could theoretically carry the recovery systems.)

As I remember there was a similar plan for the Redstone. The studies said that a rate of decent of 40 feet per second was the maximum for the booster. I wonder if the guys who designed the SRB's ever read it? In the end I guess they figured it was too much trouble. The Navy had there hands full getting the capsule back.

It has concepts for recovering the Saturn SIVB stage and the others you mention. I remember seeing concepts for recovering the S1C stage elsewhere too. I can't find the book right now, but I believe it was a book by vonBraun with "Frontier" also in the title, circa about 1969. Maybe someone else can home in on this one?

The same people who made that graph must've helped plan the early shuttle program when they were anticipating that many flights... per year!

I have found a lot of documents here about the reuse of Saturn S-II stages, different engine configurations and even it's use as a first stage! All of the contractors wanted to reuse their products. See Godwin's new lunar reference book for those ideas!
CNewport New Member Posts: From: Registered:	posted 01-29-2008 08:17 PM I think their estimate of the labor and refurbishment needed to certify an S1-C booster for re-flight is in error. Once you get sea water into the circuits and structure, it takes considerable more labor than they realize to make anything ready for flight.
Paul78zephyr Member Posts: 335 From: Hudson, MA Registered: Jul 2005	posted 09-29-2011 11:40 AM Could the S-IC stage have been recovered intact (or partially intact) using some type of recovery devices like the shuttle solid rocket motors? Editor's note: Threads merged. On edit: Okay, thanks for that info.

Thank you for posting this amazing leaflet. It was published at a time when we thought we could do anything. When physicist Neil deGrasse Tyson visited Bill Mahar's HBO show recently he said: "When America stopped going to the Moon... America stopped dreaming." I couldn't agree more.
Jay Chladek Member Posts: 2163 From: Bellevue, NE, USA Registered: Aug 2007	posted 09-29-2011 02:11 PM I believe the main reason why this idea was proposed wasn't necessarily for the lunar program, but rather Apollo Applications (AAP). 1965 was the year the first AAP office opened up and George Mueller had some grand plans for it as in that period from 1965 to 1968 when AAP got funded as its own program, there were some serious proposals for multiple space stations, lunar bases and other things and they would need multiple Saturn launches to fly. Marshall was also thinking along similar lines as well since once Apollo ended, von Braun would need to find another program for the Huntsville based NASA center to work on as Saturn was their baby and the Saturn production line would be the first element to shut down towards the end of the program. Of course in those years, NASA was dreaming rather big. Could they have done this? Yes, possibly. But it would have been a very expensive prospect. All things considered though, do you think a proposal for recoverable SRBs in the shuttle program would have been made if somebody hadn't already proposed something similar for the S-1C? Sometimes I wonder.

Sometimes I wonder. Granted the S-1C recovery proposal was done in the mid '60s, but I would think that even without the proposal, something on the shuttle would have been made recoverable. The environmental movement kicked in in the early '70s, when shuttle was being thought about and designed. That, and the energy crisis in 1973/74 made being "green" and reducing costs in some sort of way part of the national conscience.

Tony Guidry New Member Posts: 8 From: Lafayette, Louisiana, USA Registered: Jun 2009	posted 02-16-2013 08:50 PM Recently, I was viewing the CBS News coverage of the Apollo 14 launch on YouTube. Shortly after separation of the S-IC first stage, at 5:02 into the video, Wally Schirra made a comment to Walter Cronkite, "This is the one we hope to fly back sometime in the future." Did NASA ever have any plans or the capability of recovering the first stage of the Saturn V for re-use? I was not aware of any recovery system being included on the S-IC.
