I see they are using touch screens. What would they do if the screens froze?
- minkzilla 6y agoIf one freezes then use the other 3. If they all freeze let the autopilot do it's job.
- naggreg 6y agoI find it sort of weird to not have buttons in there: with all the vibrations you would think it's rather difficult to touch the exact control that you want. I guess they considered that...
- NikolaeVarius 6y agoThe exact same thing applies to buttons, its just harder to screw up. they also have buttons just fine https://spaceflightnow.com/2020/04/03/photos-astronauts-train-to-ride-a-dragon-into-space/ https://spaceflightnow.com/2020/04/03/photos-astronauts-trai...
- dahfizz 6y agoI don't think the astronauts make extensive manual corrections during takeoff. And if you watch the livestream, the UI elements are much larger on the screen than would be possible with physical buttons. So if you are worried about precision, the touch screens would actually be safer.
- minkzilla 6y agoI think the astronauts have very little to actually control. There are a variety of buttons underneath the screens, a big red one being for abort.

- elric 6y agoLooks like there are some physical buttons underneath the touch screens. Not sure what they do, but hopefully they're used for important stuff. I just watched one of the astronauts push buttons on the touch screen, and it's shocking how small the icons on the screen are relative to their fingers. I would not want to try to the hit the right icon while accelerating!
- gpm 6y agoThat seems like an unlikely failure scenario. But I imagine if that happened during launch they would pull the abort lever since that would be indicative of a significant failure. Later they and the engineers on the ground would work to control the vehicle either remotely or to fix the displays... or both. And probably abort to the ground as quickly as is reasonably possible.
- imglorp 6y agoI'm curious what the physical buttons on the seat armrests do.
- minkzilla 6y agoWhen they were doing comm checks I noticed that they were being pressed right before the astronauts would talk.
- ag56 6y agoAnd what happens during launch when — I assume — everything starts vibrating wildly? They better be enormous virtual buttons.
- NikolaeVarius 6y agoThey stare at them while waiting for the automatic launch sequence that has been in use by rockets since the early space race.
- m4rtink 6y agoActually I remember reading an article mentioning that they use vibration data from accelerometters to slightly shift content on thescreen, thus preventing the screen from appearing blurry to the crew during the launch. Pretty clever. :) But indeed, the launch is automated and for any the few important manual thing (basically just manual launch abort trigger) they have separate physical controls.
