EladDv Posted April 8, 2016 Share Posted April 8, 2016 I am pleased to announce that RSP will start a full production cycle and experiments on a new fully automated reuseable landing system. Thanks for the inspiration SpaceX Link to comment Share on other sites More sharing options...
Frida Space Posted April 8, 2016 Share Posted April 8, 2016 Elon: reusability gives 100-fold reduction in marginal costs (not fixed costs, obviously). Link to comment Share on other sites More sharing options...
Wingman703 Posted April 8, 2016 Share Posted April 8, 2016 Elon just confirmed that they want to reuse the fairings. I know that was up for debate awhile back. Link to comment Share on other sites More sharing options...
Motokid600 Posted April 8, 2016 Share Posted April 8, 2016 So they WERE testing fairings in the last launch... Wow. Link to comment Share on other sites More sharing options...

max_creative Posted April 8, 2016 Share Posted April 8, 2016 Yeah. And now that you guys are talking about reusability and the "OMG YES!!!" Has died down, I found this by @MoonMan22. His channel name is Xander. Link to comment Share on other sites More sharing options...
Aethon Posted April 8, 2016 Author Share Posted April 8, 2016 (edited) Wow.. Ok I've calmed down a bit. (tee heee) Apparently I can't post a video url with a specific time stamp on it. Skip ahead in this video to 28:25, the part I'm referencing starts at 28:30. Ignore the sound.. it's way out of sync for some reason. Did anyone notice the flames that started to appear around the tank butt, prograde of the engines at that this point? I kept thinking this was going to be a catastrophic failure. Is this normal and what is it exactly? Ok this video is messed up.. Now the point I'm talking about is at 20 minutes.

Are you referring to the landing at 27:30 ? what you see is the exhaust light reflecting against the landing legs, while they are still rotating. for aerodynamism reasons (deployed legs are extra draggy) the landing legs are deployed only at the last moment - they almost lock in place less than 1s before touchdown.

Aethon Posted April 9, 2016 Author Share Posted April 9, 2016 (edited) No. Apparently the uploader of this video has edited it. The part I'm referring to now starts at 20:00. I recommend watching from 19:50 through 20:30 or so. Edited April 9, 2016 by Aethon Link to comment Share on other sites More sharing options...
Frybert Posted April 9, 2016 Share Posted April 9, 2016 Its looks fine to me @Aethon, it looks like the plume is widening as it gets into the higher parts of the atmosphere, which is normal. I think normally SpaceX cuts to the onboard cam earlier in their casts than they did today. Link to comment Share on other sites More sharing options...

Aethon Posted April 9, 2016 Author Share Posted April 9, 2016 Yeah. That was my later explanation, less atmosphere, but it just seems like the flames are coming out ahead of the rocket nozzles. Obviously it was nominal because it was able to NAIL the landing! Wooooooooooooooo! Link to comment Share on other sites More sharing options...
PB666 Posted April 9, 2016 Share Posted April 9, 2016 (edited) I does not appear this was posted skip ahead like 9 minutes more like skip ahead 15-20 minutes, lol. Is it an optical illusion it looks like the distal edge of the F9 2nd stage is flexing and bulging. Edited April 9, 2016 by PB666 Link to comment Share on other sites More sharing options...
tater Posted April 9, 2016 Share Posted April 9, 2016 Regarding the drone ship landing "We were confident that if it did fail, it would fail for a new reason... it turns out there are a lot of reasons for a rocket to fail." Link to comment Share on other sites More sharing options...

Wooooooooooooooo! one other possibility, is that it's indeed from gas expansion due to lower pressure - but it could be coming from the merlin's gas generators exhausts.

FancyMouse Posted April 9, 2016 Share Posted April 9, 2016 Note that the speed is near the speed of sound at the time the extra flame comes - could that be relevant? I really know nothing about that and curious to know. Link to comment Share on other sites More sharing options...

I really know nothing about that and curious to know. here's something to compare it to Atlas V launch, as the atlas's RD-180 is a staged combustion cycle (no separate gas generator exhaust) https://www.youtube.com/watch?v=MkRZeEtumNE&nohtml5=False&spfreload=10 the flames that 'widen' out on the sides near max Q is mostly due to the interaction between the two expanding exhausts of both nozzles.

I am expecting +95% success rate for ground attemps and also a high rate of success for sea barge landing with a new special barge (bigger and stable). Next up: Kerbal landing rockets phase 2: HIGH SPEED BARGE LANDINGS Phase 3: Fairing reuse. Phase 4: 2nd stage engine reuse. Phase 5?: 2nd stage reuse. Go SpaceX! 6 hours ago, Mitchz95 said: Oh, please. Who cares? 6 hours ago, max_creative said: I'M OUT OF REP!!! NO!!! They should name a barge "f5" because that reloads quicksaves in ksp. Now they need to land a falcon heavy. Red dragon on Mars. FOR SCIENCE!!! FOR SPACEX!!! Red Dragon was already killed on arrival, no one wanted it, not even SpaceX.

YumonStudios Posted April 9, 2016 Share Posted April 9, 2016 6 hours ago, HebaruSan said: I chose my words poorly. Are they going to re-use this one, or the one that landed previously? Will they tell us how much it costs? When do we find out whether they've done re-use right and made it worth it? We would have thrown a party in 1981, too, but the shuttle's problems only became apparent with time. I bet @illectro is scrambling to upload something just to shut up the thousands of people asking him for his opinion. Probably this one, eventually. Only time will tell whether this end up being cheaper than making a smaller rocket expendable with the same performance overall. 6 hours ago, Robotengineer said: I seriously doubt SpaceX will release the real cost savings from reuse, given that they are already the cheapest (I think) launch provider out there. They don't plant to reuse the first one they landed AFAIK, and we'll have to wait until we see what sort of shape the one that just landed is in. Who is @illectro? Why wouldn't they?

YumonStudios Posted April 9, 2016 Share Posted April 9, 2016 5 hours ago, sevenperforce said: The first one was not intended to be reused, simply due to its nostalgic value. This one, however, is absolutely slated for reuse. Also, likely the 1st one is need to test out stuff in case another rocket goes boom, like Enterprise after Columbia. 5 hours ago, CatastrophicFailure said: So no more plans to use a re-used booster for the flight abort test? I think that was the F9R dev2 rocket they were using... Link to comment Share on other sites More sharing options...
