CatastrophicFailure Posted December 15, 2017 Share Posted December 15, 2017 Also @mikegarrison, as I understand, the return trajectory of the booster is such that if control is lost prior to the landing burn, it’ll go into the drink. A big part of the landing burn is the final course tweak to put it on target for the LZ pad. Quote Link to comment Share on other sites More sharing options...

It's a badge of honor. My track car is just filthy from brake dust and bits of rubber that have been flung onto it, but I don't wash it because this way it looks like it's actually been driven.

We have race cars in the museum that are in the same condition that they left the track, filthy and covered in confetti. Definitely a badge of honor.

I think it might just surprise us. Modern automotive paint is some pretty tough stuff, especially the high quality stuff I’m assuming they use on an expensive electric supercar. With no atmosphere to oxidize or erode it, it might take that solar heating a good long time. The interior plastic and leather, on the other hand...

The paint may suffer from heavy UV irradiation where there is no ozone layer to protect it from decomposing. Even supercar paint may not be designed to withstand cosmic levels of UV-C, which is normally completely absorbed by the atmosphere. Quote Link to comment Share on other sites More sharing options...

I was under the impression you thought that a FH launch was powered by magical unicorn chow, and hence I assumed you meant the regular Falcon .

KSK Posted December 16, 2017 Share Posted December 16, 2017 And on a serious note, I think the thing that got me most excited about the last launch was the five minutes or so of the webcast that were devoted to talking about the new pad updates. Updating the sound suppression systems for example to cope with longer holddowns - because that means SpaceX can do the refurbishment and then static fire testing of recovered boosters right there at the launch site without needing to ship their recovered boosters to McGregor(?) and back. Increasing commonality of equipment and facilities between their three launch sites which is (presumably) cheaper and easier to manage. None of which is terribly exciting from a technical perspective but from a business perspective, I'm really liking seeing yet more evidence of SpaceX' step-by-step 'having a plan and executing it' approach, all with the goal of optimising, streamlining and further lowering launch costs. The kind of quiet behind-the-scenes work that will hopefully let them deliver on more of Elon's more aspirational goals. Quote Link to comment Share on other sites More sharing options...

It is pretty tough stuff but it will be in an environment that it wasn't designed for. It will probably look like a car that's been sitting in a barn for 40 years after a short period of time whose duration I'm completely unqualified to guess at. There is a non-zero chance that it has structural failure after being exposed to space. The Roadster and the Lotus Elise which it is based on have a bonded aluminum structure. The adhesive could easily degrade rapidly in space and thermal expansion of different parts could easily put unforeseen stress on the joints. 2 hours ago, KSK said: None of which is terribly exciting from a technical perspective but from a business perspective... <snip> You'd be surprised at what gets us technical people excited. I'm a firm believer in simplicity which usually translates to less expensive which the business people like. The person that asks me for more "wow factor" had better be ready for a rant on unnecessary over-complication. Quote Link to comment Share on other sites More sharing options...
