I found this interesting: NASA RELL (Robotic External Leak Detector) [1].

    "NASA’s Robotic External Leak Locator (RELL) is a robotic, remote-controlled tool that helps mission operators detect the location of an external leak and rapidly confirm a successful repair. 
    … Two instruments working in sync give RELL its ammonia-detecting superpowers. … Mass spectrometer & Ion vacuum pressure gauge"

I’m imagining the robots from Silent Running 1972.

“You crawl around outside and smell for astronaut wizz.”

One thing that’s rarely discussed about spaceflight is that for the foreseeable future, it will have to happen without the animals that humans rely upon on Earth. I think this will expose just how strong that reliance is in some areas.

I wonder about what happens to gut micro biomes

They'll standardize so that everybody has more or less the same stuff.

...or the scutters on Red Dwarf.

How cool, "ion vacuum pressure gauge" is basically a conductivity sensor with ionizing voltage.

Now I wonder if it basically lasts forever or if it has problems with corrosion.
