NASA goes to obscene lengths to sterilize spacecraft, but once people start going all bets are off. I doubt there would be any meaningful results from such an experiment before human explorers arrive.
Even when humans are getting on the rocket everything is assembled in a clean room. Human skin oils do not mix well with stuff in space, so they dont like to get it on anything that moves, or holds, or even looks like it might do something that has a purpose.
Filthy humanses.
We can name in the A.c.h.o.o., which stands for achoo, and it’s just Earl going in and out of the airlock and sneezing at planets.
That’s how weird space religions that worship sneezes are born.
Praise the Great Green Arkleseizure!
The end is nigh! The coming of The Great White Handkerchief is upon us!
I mean, it sounds like a very expensive way to kill some earth-based life.
Isn’t that how earth came to be?
Actually we do know.
Most precursors to life have been found in asteroids.
Life is everywhere in the universe, we are just too tiny and incapable to know that.
Edit: also too fucking arrogant. It is very clear to anybody with a scientific mind that has paid any sort of attention, we, like everything else, are products of exploding stars. There is not one single thing unique about Earth.
Edit2 For the knee jerk unscientific down voters… Here’s a little video for you, I’m sorry it doesn’t use finger puppets or sock puppets… It’s PBS SpaceTime which is for children…still might be a little too advanced but you could give it a try https://youtu.be/nKb4zcyqjXQ
Precursors aren’t life. I agree life is somewhat abundant in the universe, but amino acids on an asteroid is not life.
great point man, people downvoting you for nothing lol. are they earth worshippers.
It’s all the flat earthers who lurk in this community.
I will believe this when you can point to the planet our life came from.
Mars had a warmer, wetter, period is its past. It has been hypothesized that Earth life could have come from Mars, though there is currently insufficient evidence to make a definitive conclusion.
May not have come from a planet. There’s a theory that the young universe was at habitable temperatures literally everywhere at one point, so it would have been trivial for life to begin. Plus the universe was way smaller and denser than, so it would have been easier for that life to travel everywhere.
Literally any rock in space could have life hidden in it.

I think you mean “hypothesis”

There was a significant - over half a billion year - gap between the formation of the Earth and the earliest traces of life.
Was the gap between Earth and the Sun habitable during this period?
Yes, it’s a hypothesis if you want to be strict about it. I don’t feel like arguing with a pedant today so here’s a short paper for you to read about a proposed habitable cosmological epoch: https://arxiv.org/pdf/1312.0613
Abraham “Avi” Loeb
In 2018, he suggested that alien space craft may be in the Solar System, using ʻOumuamua as an example. In 2023, he claimed to have recovered material from an interstellar meteor that could be evidence of an alien starship, which some experts criticized as hasty and sensational, and other experts showed that Loeb mistook ordinary truck traffic for a seismic evidence of the meteor, causing him to look hundreds of miles in the wrong direction.
This is absolute fucking horseshit.
Honestly, the content and quality of this sub has reached the point where I’m just leaving.
Or, hear me out, filter posts with URLs from iflscience, sciworthy, etc.
