Mmmm, that frame looks pretty permanent to me. But I guess the picture doesn't really show how it is attached to the foundation.

Raven Industries Posted July 11, 2019 Share Posted July 11, 2019 You know, the whole build the Hoppers in a field thing might be partially intended as a marketing tactic to promote SpaceX as compared to competitors that use a more conventional method of construction: "Our vehicles are so reliable that we can build them in in the open, exposed to dust, dirt, and the elements, and they'll still work perfectly fine."

The thing is, these rockets (well not these specific rockets but this design) will hopefully eventually have to spend a year or two out in the open, exposed to the Martian environment, so it's good practice.

Guest Posted July 11, 2019 Share Posted July 11, 2019 (edited) I feel like it has more to do with the construction method and timetable. Trying to assemble them on their side would probably add difficulty complexity to the assembly process. And where else could you get a building with the headroom to fit a rocket upright besides a NASA style VAB. (Are there any available to rent out? XD I have no idea but I bet a crane in a field is a lot cheaper.) Building them out in the open has proved invaluable though! Imagine if they built hopper in a VAB and when it came to testing the top half broke off in flight under aerodynamic stress @_@! That would have been bad...

tater Posted July 11, 2019 Share Posted July 11, 2019 It's important to realize that the first few vehicles likely end in a very, very kerbal way. That would be true regardless of how they were built. Quote Link to comment Share on other sites More sharing options...

They are too beautiful to die :3 (besides hopper... hopper you can have, it has lost some appeal for me now its gone all stumpy) Edited July 11, 2019 by Guest Quote Link to comment Share on other sites More sharing options...

There’s no accounting for squirrels of course but I think they’ve had the rusty bolts thing figured out since the first Falcon 1 flight.

Hate to break it to you, but ground squirrels nest in the ground. It's kind of their thing, you know? Quote Link to comment Share on other sites More sharing options...

Guess they will need an VAB down the line, payload integration is an obvious one. they will also need to jack up to replace engines, at least the vacuum ones. Sideway would not be very practical because of the width as you will need scaffolding anyway and now everything is sideways. Much easier to have all critical systems either on bottom or top.

kerbiloid Posted July 11, 2019 Share Posted July 11, 2019 (edited) When a rocket is landed, it can be considered as a ground installation. So, the ground squirrels may use it until the launch. Especially, when it looks like a barn. Edited July 11, 2019 by kerbiloid Quote Link to comment Share on other sites More sharing options...

CatastrophicFailure Posted July 11, 2019 Share Posted July 11, 2019 (edited) Also, found this: https://www.teslarati.com/spacex-falcon-fairing-upgrade-foiled-by-ula/ Apparently SpaceX is possibly in the market for that larger fairing it’s always said is needed around here, but may have faced interference from ULA. I can’t help but see this backfiring for ULA, as SpaceX has already demonstrated they’re more than willing to say, “oh yeah?? Well we’ll make our own fairings, with blackjack and—“ Well, you get the idea. Edited July 11, 2019 by CatastrophicFailure Quote Link to comment Share on other sites More sharing options...

Wonder how much is just test instrumentation? Lots of it, also you can trade reliability with increasing complexity in lots of fluid systems. Its why you see 6 valves many places just 1 would be needed. You have two redundant flow control valves, each lines has two cut of valves who is both manual and remote. if primary fails you close its cut off and open the secondary cut off. You can now pull and replace primary control while running if both cut of works manual or automatic. Quote Link to comment Share on other sites More sharing options...
