Well I did fix the car. 😉

It was pretty crunched. In theory I could weld it but I ended up just buying a new pan.

Iron dissolved in a solution eg with an acid or glass is not magnetic. If you added the ferris sulfate to the rock and then oxidized it to iron oxide then it would indeed make the rock magnetic.

actually, I think I've thought of the same thing and yeah, I'm pretty sure it will work. the main issue being that the material will need to be dry and not frozen. Unfortunately, it is neither this time of year.

Nope.

They can and almost certainly have but there is a huge difference between a few freeze-dried cells clinging to the side of a rover and the active biosphere that a human would bring with them.

Much obliged, copyright claim sent.

Similar initial and growing conditions but its not perfect so most snowflakes arnt symmetrical including some of the ones shown here.

I swear one day I'm going to build a dirigible just to get above the clouds.
