"Our aspirational goal is to send our first cargo mission to Mars in 2022. The objectives for the first mission will be to confirm water resources, identify hazards, and put in place initial power, mining, and life support infrastructure. A second mission, with both cargo and crew, is targeted for 2024" -- spacex.com/mars

Maybe NASA should book space for a biologist on that flight. A botanist would do.

IDK, what would be the motive to hide that?

Not that I think there's a conspiracy, I don't think one has to try very hard to imagine reasons why the powers that be would suppress such discoveries.

Consider for instance how many US citizens are still religious today, and largely govern their lives according to religious beliefs. Consider how the current president has deliberately weakened the separation of church and state by making it legal for churches to be political - pastors of tax-exempt churches can now outright advise congregation on who to vote for.

Discovery of life elsewhere threatens the foundation of a lot of religious dogma.

I get the feeling that contrary to rhetoric the search for life on Mars or anywhere else is almost an anti-priority. Not much designed to look for life has been sent since Viking in spite of direct observation of water ice, brine, and other features suggesting ideal landing sites for such experiments. If perclorates were the cause of the Viking positive as many suggest, why not send a new experiment designed to rule…

I think it's the opposite. There are scientists who are obsessed with finding extraterrestrial life because of their philosophical views regarding man's place in the universe. The fact that our universe seems primed for life has bothered so many gung ho atheistic scientists that they've conjured all sorts of semi-pseudoscientific multiverse theories (Sean Carroll). That's one part of it. The second part it's reducing…

Methodological naturalism as applied to the scientific Certainly has no dependence on atheism.

Who categorizes science as an intrinsically atheistic endeavor other than religious apologists?

I often wonder why these are always auxiliary conversations. Ever since I was young, like most kids (I have 4), I also had this deep yearning for knowledge on life external to earth. Wonder why this never has gone mainstream.

Let's assume for a moment that we did find something resembling simple organic life on Mars and confirmed that earth isn't the only life bearing planet. What functionally changes for our existential understanding of the universe? I'd argue little to nothing. We'd learn a bit more about organic life, but no fundamental philosophical or existential questions would be resolved. Life has been confirmed to be able to thrive in many more extreme places here on earth than anywhere observed on Mars. There wouldn't be any firm resolution on the question of whether humans are the only intelligent species in the universe.

I think that would be a different answer if we found inorganic life, as that would blow up the concept of organic life as singular in "life" bearing capability. I doubt we would recognize inorganic life as "life" in that case however, as humanity has a poor working definition of "life."

Absent a recognizably intelligent form of life found off planet, I doubt much would change (practically or existentially) for us here on earth.

I wonder if there is an incentive to NOT find life there because of what that discovery might do to slow industrialization and colonization plans. Do we need to conserve that life? Do we need to set up preserves that are off limits to development? Opens a big can of worms (or bacteria) that I imagine some would rather see kept closed

The priorities currently for Mars seem to be gathering correlated data to strengthen or weaken the case overall. https://mars.nasa.gov/mars2020/mission/instruments/

2x. Look at the test suites on everything we've sent since Viking. Viking gave us odd results so we've set out to do a good job proving things one way or the other.

I mean, you're probably right. If there was life found on Mars, there would be precedence to protect it - I could see this even stopping ANY manned missions (fear of contamination).

If the planet is dead, we as a civilization get the privilege to do whatever we want with it. Also a dead planet means the idea of the Monotheistic God kind of remains.

Ignorance is bliss.

> On July 30, 1976, the LR returned its initial results from Mars. Amazingly, they were positive. As the experiment progressed, a total of four positive results, supported by five varied controls, streamed down from the twin Viking spacecraft landed some 4,000 miles apart. The data curves signaled the detection of microbial respiration on the Red Planet. The curves from Mars were similar to those produced by LR tests…

It seems like one could replicate this experiment on earth and verify non-biological origins for the observed results. I'm pretty sure we're familiar with the composition of martian soil by now. Create a sample with similar composition, blast it with UV rays in an atmosphere similar to Mars, and subject the soil sample to the same test.

People always claim this, but I'm not convinced. We've had a million scientific discoveries that for all practical purposes disprove a lot of religious claims. People seem to either just adapt their beliefs, ie. things move from literal to symbolic, or people simply choose not to believe or consider the facts despite clear evidence. I don't think simple facts or evidence will ever seriously threaten religious dogma for at least some portion of the population.
