CRS-11 is on its way
SpaceX just launched CRS-11 on its way to the ISS and it looks to have
been a successful launch and a successful landing of the first stage at LZ-1 (spot on the center of the pad). Also, I believe that CRS-11 is reusing the Dragon from CRS-4 after some refurbishment of course. As with the first refurbished first stage reuse, it's unclear exactly what they replaced (besides the heat shield) and how much it cost. But it's nice to see SpaceX at least trying to reuse as much hardware as they can instead of throwing it away after one flight.

Frankly, I'm surprised NASA let them do it and didn't insist on all new equipment. -- "The reasonable man adapts himself to the world; the unreasonable man persists in trying to adapt the world to himself.

About 20 minutes after launch, the Dragon, second stage and solar array covers were naked eye visible passing over the UK. https://www.youtube.com/watch?v=7Qw-w31TVAE (Not my footage) Anthony |

Frankly, I'm surprised NASA let them do it and didn't insist on all new equipment. As I recall the original contract for CRS restricted the use of anything re-used. That must have changed (and that's good). I'm waiting for the first CRS with re-used Dragon AND 1st stage. -- Greg D.

After separation from the Dragon, it continued, to do its own thing; it may be still up there, for tests. Conceptually, would it be possible to make the propulsion module re-renter and be re-usable? (thinking a heat shield on its top (against Dragon,s heat shield) so it would re-enter head first. It is sufficiently conceptually possible, so that SpaceX are intending to start attempting second stage recovery quite soon. As was done with first stages, the plan is (I think) to attempt partial recoveries first - i.e. don't provide a landing place until tests have demonstrated coming down at the chosen place, the correct way up, and at near enough zero velocity. If you were to read a few reputable and relevant web sites (etc.), you would not need to ask such questions. In this case, search for falcon second stage recovery . -- (c) John Stockton, Surrey, UK.

No, I meant the power/propulasion part of Dragon spacecraft. The thing that fires the de-orbit and then separarte from Capsule. Capsule survices, it burns up. I don't think the part you're talking about actually exists. Doesn't Dragon V1 use its OMS for reentry? There is a 'power trunk' that is tossed. Was wondering if making it survive re-entry and land might be possible. I would guess anything is 'possible', but it would undoubtedly be stupidly expensive and cost you trunk cargo space, so it makes no sense to do it. Right now what you're throwing away is a couple of solar panels and wiring, cargo racks, and some aluminum structure. Making that stuff robust enough for reentry (including somehow protecting the solar arrays after they've ejected their covers) would probably cost more than building a hundred trunks of the current design. You'd also need some way to guide it (it's the wrong shape), heat shields, and parachutes to get it down. There are no engines in there. -- "The reasonable man adapts himself to the world; the unreasonable man persists in trying to adapt the world to himself.
