What happens when we'd put some microbes there now?
I've been curious about this recently actually. What are the downsides of "seeding" a plant with life to study how it evolves?
(There is a hypothesis that life may have been introduced this way to earth, known as the Panspermia Hypothesis https://en.wikipedia.org/wiki/Panspermia)
Here's a YouTube talk with some of the arguments: https://www.youtube.com/watch?v=0cwvj0XBKlE
For almost half a century, scientists have been speculating about sub-surface life on mars. Why with existing technological progress can we not just get a yes or no answer about this.
Part of Perseverance's mission is to take those soil samples and deposit them to be picked up and brought back to Earth on another later mission.

things that go to mars tend to stay there
That's changing very soon. Perseverance's mission includes collecting and storing samples for a return mission. https://en.wikipedia.org/wiki/Mars_sample-return_mission
I don't understand the excitement for finding life on Mars. I personally really, really hope we do not find life on Mars. If we find even the most basic microbial life, NASA is going to shut down all future exploration in the interest of Martian planetary protection. China and Russia probably won't, but the US will cripple itself (again) out of caution. On a more existential level, finding life elsewhere in the solar…
is anybody going to talk about the numerous and very obvious artificial structures on Mars and Moon? Just shut up and chalk it up to conspiracy right like a good American.
I'm a PhD candidate studying Mars, happy to debunk any structures you can supply.
Literally pyramids and megastructures with uniform and clear patterns of engineered structures. There's really nothing you can say here to convince me otherwise. There's zero chance of a large pyramid structure with accurate math proportions and geometric consistencies occuring by "chance"
I don't know about other stuff you are speaking of but there's almost no explanation you can give to convice the 47% of the Americans that don't believe you.
edit: also there's no need for personal ad hominem attacks in your other reply. it's unprofessional. we are not even limiting this to Mars, I mentioned the Moon as well.

The only obvious examples of either are the ones humans put there — the probes, the rovers, the Apollo Lunar Modules and associated material.

I’ll answer your question with a question. Would space exploration get more or less funding if we settled a fundamental question about the existence of life outside earth?

The great filter is that tech is to easy, but self-awareness and self-discipline is hard. So life presses onwards, demanding exponential energy density from tech, to not be forced to limit itself and self-discipline itself. Thus ever more potent tools are handed out to avoid confrontation with the "overcome" animal nature - and once that equation reaches the end of the line (easy energy and resources exhausted), a ne…
There could be civilizations out there that never developed aggression.
So they either have an abundant source of nutrients that has not been depleted for their entire evolution, or they are not highly developed, or they have developed aggression.
