Anyone else wondering if NASA is working up to a 'find' of some obscure ice-seep-scum microbe or whatever, which is then declared endangered, and so SpaceX gets banned from going to Mars? Because the poor microbes...
Of course NASA would love to discover extraterrestrial life, but that has nothing to do with SpaceX. It would likely be the biggest scientific discovery in decades, maybe ever. A ban on "frivolous" Mars missions would be a logical next step. It'd be very important to thoroughly understand the nature of this new strain of life before doing anything to endanger it.
Define "frivolous". Would your definition by any chance be close to 'not controlled by government bureaucracy'?
Also explain how 'understand the nature of such life' could happen without manned Mars missions. Building a robot to detect presence of some life-indicating molecules - feasible. Building a robot to explore the molecular machinery, metabolism and behavior of any form of life - not feasible, ever. Not without full, strong AI capable of the complete scientific method loop, and running a general manufacturing setup. In which case, we may as well just kill ourselves already.
I knew I could count on someone to fail to get the joke, even if it's not totally a joke.
By the way, in my opinion Mars very likely has a dense atmosphere, plenty of liquid water, and even a complex biome.
Not on the surface, but in vast, deep underground caverns formed by the thermal contraction of the planet's original magma core as it cooled and solidified. When you shrink the entire internal volume of a planet by a few percent (as magma does when cooling), that's a HUGE amount of space. Easily enough to swallow the planet's entire original atmosphere and oceans. Previous post:

Good luck designing lander robots to find out, by finding entrances then cave exploring downwards hundreds of kilometers.
Lastly, discovery of life on Mars is only going to be a big thing to those who, for whatever reason find the concept of non-Terrestrial life challenging. Those of us who don't subscribe to the human-centric religions, and expect that organic life is pretty common in the universe, will just be mildly pleased by the definite discovery of life on Mars. Kind of 'told you so' satisfaction. Most of the fun will come from observing the religious institutions have conniptions.
