Okay, so I'm seeing the original Alien
rebooted on the ISS? Yeah, plausible because the ISS and its biology lab (which is on Columbus, IIRC) is probably the single best isolation lab possible for a xenobiology investigation.
The bit with them using DEXTRE to capture an out-of-control ARM sample return pod (because that is definitely
what that looked like) was a wonderful part of Hollywood reality; I don't think that there's any bit of RL telerobotics that could react that fast! That said, I strongly advise against using a flame-thrower
in a spacecraft with an oxygen-rich environment as well as using a rivet gun
around pressurised modules.
But I commit the crime of treating a popcorn movie as a documentary, which is bad form.
