Hopefully some engineer on the ground used Emacs to access the command line remotely, to run Vim, so that we are back on equal footing :D

Using it with a 20 minute delay between keystrokes and their results must be interesting

I'm sure they didn't connect to it via the internet to send keystrokes.

Huge delays between keypresses is what vi (and vim ofc) was designed for.

What make & model of camera are these?

They're USB cameras. I don't know the vendor, but I worked with 4 cameras wired back to a small Linux computer.

FLIR Chameleon3 connected via USB to a Intel Atom Linux SBC running ffmpeg to encode the video.

I am really surprised they are using essentially off-the-shelf USB cameras. I guess if it works, it works, but surprising that they didn't need to design circuitry to work in a space environment.

I am guessing the requirements for circuitry operating on Mars isn't quite as much as a spacecraft or satellite, but it is still getting hit with cosmic particles and solar radiation with no atmosphere.
