The most entertaining part is the text to speech. That will speak everything you type into chat in a lame as voice.
Oh and there's also a word filter. Piss get's replaced by **** but poop goes right trough
I think the fastest way to finish the mission is to first look at the map and see if there are 1 or 2 heavily damaged solar arrays. Taking 1 array replacement and a welder or two replacement and carrying them with the buggies depending on the case. (Two astronauts are needed for this) After they are finished they'll either help with wrenching the tubes secure or getting a bot and welding the broken filter components.
The next three astronauts start by repairing the tubes. They will begin with the tubes coming from the array's that will be replaced instantly or repaired swiftly. Ignoring the first connector going critical since it's almost impossible to fix it in time. And there's a replacement for it near the array's anyway. They then work their way to the last of the tubes. Afterward they grab some spare parts for the filter or a welder bot and uses them near the filter.
The last astronaut starts with a handling robot and uses the parts that lies around the filter and possibly new parts dropped there to replace the empty slots and or red damaged parts. Afterwards they switch to a welder bot to repair the small damage.
