I would guess that as well. For one thing they are larger (17" screens vs 15" screens) and are likely to be hardened for the rigors of space, as you mention.

We all know these control panels are in a climate controlled environment suitable for humans right?

Yes, but the question comes up for when they are not. Apollo 13 again comes to mind. The environment was (barely) tolerable for humans but the condensation and other conditions was havoc on critical equipment. The command module was basically at or below freezing and was water soaked.

I think primarily we don't know enough about the Dragon crew capsule and I couldn't find any good information on the screen tolerances.

I don't think any engineers envisioned an Apollo vehicle getting into that state to begin with. It was a miracle they were able to recover the crew of Apollo 13. You cannot really design a system assuming it will continue to function after complete system failure. I don't think the dragon is supposed to leave LEO, so that's not likely a concern.

Lots of designing for triple failures happens in aerospace, and I haven't even worked on manned missions.

Yes, triple redundancy in critical subsystems is pretty standard nowadays. When I say complete system failure, I mean you have burned through all your redundant elements in at least one critical system. Apollo 13 was in that condition (though they might not have had as much redundancy as modern systems). Hence the famous co2 scrubber adapter.

I'm sure it is a lot different going 250 miles up in a low earth orbit vs 250,000 miles up.

You are correct, it isn't, although I thought originally it was. Dragon is capable of reentering earth's orbit from a lunar or further mission, but it doesn't appear to be selected for that (that is Orion and Starship).

Starlink-7 : SpaceX launched another set of starlink sats, landing the booster for a 5th time (nice ROI there).

Boca Chica : SN/5, SN/6, & SN/7 are being stacked. The test stand repair is near complete. Should see testing resume soon, fingers crossed!

Update: Looks like Netflix got to the Space Force trademark before the USGOV, yikes. lol

Ah yes, SpaceX: simultaneously taking USG money to make manned missions cheaper/safer and making LEO a more dangerous place at the same time.

BTW "Space Force" is great, highly recommend.

FYI, Rocket Lab is launching in a couple hours. Worth a watch if you have never seen an Electron rocket launch. They book-it into orbit! https://www.rocketlabusa.com/live-stream/

Launch called off due to wind. Next window: 13 - 24 June UTC

brewloc · 06-12-2020, 06:21 PM

Two launches scheduled for overnight.
SpaceX: Starlink-8
RocketLab: Don't Stop Me Now

Both missions were successful.

FYI, private beta testing for the StarLink network began on 6/12.
