And I thought I had it bad in my kitchen. In any case I'm really wondering how it grows outside, which the article didn't really explain. It's one thing for the spores to survive in vacuum, another altogether for it to actually grow in vacuum. Or did I misunderstand something?

This. Anyone explain?

Well that is an interesting result. Also bodes well for the pan spermia crowd, they are the ones that think an asteroid impact can bring life to a planet and kick off the whole life cycle. Certainly the center of an icy mass probably stays well within the survival parameters of these forms of mold. Also interesting to see if we can deduce the DNA changes that lead to this resistance. It would be an advantage for astr…

Is the Andromeda Strain good? I have heard about it.

"The research touches on this, and it warns astronauts to follow recommended planetary protection protocols designed to prevent visiting spacecraft from contaminating other planets and moons in our solar system with microorganisms from Earth. The study suggests that, because of the risk of contamination, these fungal spores may need to be considered a more serious threat." This makes me wonder if we've accidentally a…

Seriously, is this a threat or is it the unexpected boon of getting a jump-start on terraforming? If you could press a button and "contaminate" Mars with life that would start spreading and generating an oxygen atmosphere, wouldn't you?

No. Mars has a weak magnetic magnetic field which is incapable of containing an atmosphere that would support us. It also took Earth over 1 billion years for atmospheric oxygen to accumulate in significant amounts.

It would mean you have a much harder time finding out if Mars once had life, if instead you're detecting mold that hitched a ride with your spacecraft.

That's fine though. Having a second home for humanity is more important than maximally preserving the ability to detect past life (note that we wouldn't be eliminating that ability, just hindering it somewhat). Also, we think we'd be able to tell pretty easily whether any life detected is from Earth (i.e. we brought it along with us). Life that isn't descended from the same tree of life as us is likely to be radicall…

Mars will never be able to be a "second home" for humanity: it lacks the ability to maintain an atmosphere that can support humans due to its weak magnetic field.

The bottom of the ocean would be far more habitable if we faced any type of extinction event.

It is a pretty entertaining book.

An armchair explanation might be that a hurricane or tornado might be able to do this. Water spouts have scooped up fish into the sky only to dump them on land hundreds of miles from shore. https://www.dailymail.co.uk/news/article-1254812/Hundreds-fi...

In Ben Rich's book about the Skunkworks, one of the aircraft (U2? SR71?) was encountering high-altitude insect impacts on their windshields. Turns out they'd been lofted up there by nuclear tests.

Absolutely the best book, everyone here should read it.

The bottom of European ocean?

I was a huge Crichton fan when younger, and Andromeda Strain and most of his earlier stuff is head and shoulders above later work.

The movie isn't bad either.

I'd definitely skip reading anything newer than Lost World. Like Tom Clancy, at some point (and $) you lose the fire to write.

The bottom of the ocean on Earth.
