As clever as that may be, it is still a workaround for a problem that shouldn't even exist.
Astronauts on Soyuz and Shenzhou do not have any problem with vibrations making the screen unreadable. That's because they don't have a vibration problem. Soyuz and Shenzhou are launched on liquid rocket boosters.
Similarly, astronauts on Dragon won't have any problem seeing the screen due to vibrations. The Falcon 9 is also an all-liquid rocket.
The reason that SLS/Orion will vibrate so badly is that it uses solid rocket boosters. The SLS uses SRBs because it is required to use shuttle-derived components. The shuttle used SRBs because they were cheaper than the proper solution of designing liquid rocket boosters.
This sums up, in a nutshell, what's wrong with the American space program. A budget expedient from the 1970s is forcing technical workarounds well into the 21st century.
- criley2 12y agoYou're being downvoted but you're absolutely correct. Even today, in the 21st century, the US Congress mandates Solid Rocket Boosters in all NASA heavy lifters, as a Congressional mandate with strong oversight on design to ensure compliance. The reason is purely political. There is no engineering or scientific benefit to SRB's, not a single one. But there are benefits to propping up SRB companies with NASA purchase mandates that we source ICBM stuff from.
