I doubt it. They may find Death there. Dead stuff. But nothing living.
I doubt you will find life anywhere on the surface. Ultraviolet rays and harsh conditions kill anything that is exposed on the surface. You need to go down. Deeper. Down into the canyon. That's where life went ... if it was ever there. Life retreats underground here on earth when surface conditions become too dangerous. Why wouldn't it do the same on Mars?
I predict that if Life is found on Mars it will be found in the Valles Marineris. Not anywhere on the surface.
"Known as Valles Marineris, this system of deep, vast canyons runs more than 2,500 miles (4,000 km) along the Martian equator, spanning nearly a quarter of the planet's circumference. This gash in the bedrock of Mars is nearly 10 times as long as Earth's Grand Canyon and three times deeper, making it the single largest canyon in the solar system " and, according to ongoing research from the University of Arizona (UA) in Tucson, one of the most mysterious." www.space.com
It's the biggest feature of the planet and the largest in the solar system and we still haven't come close to exploring it. What's the hold up?
Talk about your elephant in the room. It's right there! And it's very deep. It's so deep that the air pressure and temperatures down there may even still support some live Extremophiles.
What the heck are we waiting for? It's right there waiting for us to explore.
Maybe Elon will be the one brave enough (or foolish enough) to be the first to go there.
After all it is ~87 million miles away. And we still haven't even discovered all the Life that is right here on Earth.
