SpaceX Returns To Flight, And Nails Another Drone Landing (cnn.com)

Posted by EditorDavid on Saturday January 14, 2017 @12:34PM from the final-frontier dept.

Applehu Akbar writes: SpaceX successfully launched a 10-satellite Iridium NEXT package, and then landed on a drone ship — this time from Vandenburg AFB in California. The launch had been delayed several days by this week's record rainfall and flooding.
CNN has video of the launch, and points out its obvious significance. "Because rockets are worth tens of millions of dollars, and they have historically been discarded after launch, mastering the landing is key to making space travel more affordable... Saturday's launch marks the seventh time SpaceX has successfully landed a rocket."

  It depends what you mean by "refurbishing"; each element is different.
  The solid rocket boosters, for example, suffered a hard impact into salt water. They then had to be fished out of the water. And of course you don't just "refill" a SRB, they have to be taken apart and recast, then put back together.
  The ET is disposable, and had to be rebuilt from scratch.
  The orbiter was legitimately reusable, but with design flaws.
  I don't blame the shuttle program - they were sort of pigeonholed into this dead end by circumstances. The concept came about during the heyday of the Apollo Programme, when NASA budgets were serious. It was supposed to be a much more reusable, much more maintainable, and somewhat smaller system. It was supposed to then have a huge flight rate supporting all of these big projects that were on NASA's docket, including a permanent moon base and a huge manned orbital station dwarfing ISS, which was supposed to replace Skylab.
  But of course, Vietnam and the realities of having soundly trounced the USSR in the space race led to their budgets being slashed, which pushed the program into ever more untenable positions until it was nothing more than a jobs programme. Forget full flyback reusability of all parts. Forget the titanium frame for the shuttle, which would have let it run hot and thus not required so sensitive of a TPS. Go begging for money and be forced to modify the design to meet Air Force requirements, pushing you into an inferior design position. On and on.
  If I'd fault them for anything, it'd be for going straight for a full reusable workhorse rather than a small-scale pilot programme first. But those were the days of optimism. Optimism which only recently seems to start being regained.
  Either way, the Falcon boosters are a very different beast. A vertical soft landing is hugely different from the SRBs, yet the thermal issues are far easier than with the Shuttle. And the Merlins were designed from the start under the principle of preventing the need for a full teardown. That doesn't mean that they will be cheap to reuse. But it does mean that they have the possibility of it.
  I do think SpaceX had a rather clever strategy, in that while their goal was reusable, they made a rocket that in the process was cheap as a disposable. So they could get volume and flight history while working on getting the kinks out. They may have flown too close to the sun with the densified propellants and (externally) unlined COPVs, but obviously, with a company like this, their whole existence is to push the envelope.

  Not true. When a booster is a few 100 km downrange and moving at a few km/s, turning it around and bringing it back to the launchpad takes a fair bit of fuel. Not loads of fuel, because the booster is pretty light at this point, but more than you'd carry just as a contingency.
  You're correct that the cost of the actual fuel is negligible, and so the GP is incorrect that the cost of the additional fuel makes recoverable boosters less economic. There is, however, a real problem: because you need to separate the first-stage booster while it still has some fuel left, your second stage needs to do more work, and so it can't carry as much payload to orbit. You lose something like a third of your potential payload. It's still worth doing - I'd prefer to put 20 tonnes in orbit at the cost of 0 boosters than 30 tonnes in orbit at the cost of 1 booster - but it's not quite as nice as it might be otherwise.

Even if some of the engines are weakened the recovery the subsequent testing should single them out for replacement. And even if that testing misses the odd engine one Falcon flight has already shown that an the rocket can survive even an explosive engine failure (CRS-1 launch). At most they might have to tweak some designs and launch methodologies. As long as they can tease out some of their other gremlins (the pressurization tanks/struts) and keep up their recovery rate they should drastically reduce launch costs.

  That's what worries me about their plan to put a customer cargo on top of their first launch of a re-used booster. Yes, they've run a load of static fire tests, and yes, I'm sure they've done a very thorough inspection of the structure, but the stresses of launch are high and you'll only really see how re-usable it is when you actually re-use it.

  There's an argument to be made that the return flight is a second stress test. The booster is flying at Mach 10 above the majority of the Earth's atmosphere. Then it intentionally dives back in. Coming back in is very nearly as tough on it as going up was. Other first stage boosters actually break up in the atmosphere when they reenter, it's so tough to do. The Falcon 9 booster not only makes it back into the atmosphere, but flips itself end-for-end twice, which has gotta be a severe lateral jolt, and then soft lands. That's three kicks to the pants (deceleration burn, reentry burn, landing burn), and two kicks to the head (flipping once for deceleration and once for landing). That sounds worse than the trip up and out, which is just one long steady push with some buffeting along the way.
  Falcon 9 first stages already survive far rougher treatment than any other rocket ever has. Given how many of them have made it back in one piece, it bodes well for the re-use case.

Good luck with that. No, seriously, good luck with that; I won't be expecting anything close to that, but please by all means prove me wrong ;) ITS would be a great system to have, I've been playing around with some Venus trajectories with it recently. Looks like it can do a low-energy transit with nearly 300 tonnes of payload from LEO and back again with the same, over 400 if starting at a high orbit - but from an economics perspective the high energy transfers actually make more sense.
I noticed a lot of people were confused about why Musk wanted the trips to be so short and was willing to sacrifice so much payload to do so - many assumed it had to do with radiation or something. But the issue is, when your craft costs so much but your launch costs are cheap, you can't have it spending all of its time drifting in deep space, you need to get it back for a new mission as soon as possible. There's a balancing point, in that if you try to go too fast, you reduce useful payload below the point of making up for it with going faster - but a minimum energy trajectory is just not optimal when the ratio between launch costs and transit vehicle cost is so extreme. I come up with the same thing from Venus as they were getting for Mars, although for the Venus case you end up aerobraking to a highly elliptical orbit rather than to the surface for ISRU refill (you need ISRU, but for the ascent stages, so it's not realistic to do so for the return stage in the nearer term). So for Venus they get no refill like on Mars, but they also don't have to do a powered landing nor do an ascent on return - it's six of one, half a dozen of the other. Both are quite accessible with it.

  Infact, i'd bet NASA would goto Musk at that point and just ask "hey what if we just fill it with fuel, and some science equipment, could we just buy the craft and send it out there never to return to see what is there and perhaps drop a bit of science equipment down the way??" ... Knowing musk he'd be happy to, and would probably jump to the opportunity and maybe even cut away the SpaceX profit margin effectively subsidizing NASA just to see it happen.
