Four billion years back, a colossal body of water covered Oxia Planum, a now-dry and desolate spot just north of the Martian equator.

“It might have been the bottom of a sea or large lake,” says Jorge Vago of the European Space Agency.

Mars then was much like Earth, with moderate temperatures, a substantial atmosphere, and lots of liquid water on the surface.

Mars today has none of those things. Nighttime temperatures reach 150 below zero Fahrenheit. The atmosphere is one percent of Earth’s. Seas and lakes, at least above ground, are missing.

Yet eons ago, within the ancient waters of Oxia Planum, life may have once flourished.

“This is a place where we think life may have appeared,” says Vago, the project scientist for the new ExoMars 2020 mission. “That’s why we chose it as the landing site.”

ExoMars 2020 is a joint venture. ESA is building the rover, Rosalind Franklin; Roscosmos, the Russian space agency, is delivering Kazachok, the “surface platform,” a stationary robot that will measure the Martian environment—air and ground temperatures, the ultraviolet radiation hitting the surface, the amount of water vapor in the atmosphere.

The launch window, next summer, is between late July and early August. The landing, about eight months later, happens March2021 This is ESA’s third mission to Mars; the first commenced 16 years ago this month, when the orbiter Mars Express lifted off. That spacecraft, still working, has imaged virtually the entire surface of the planet.

The ExoMars rover—solar-powered, cameras on its mast—will go slow across Oxia Planum, perhaps slogging the length of a football field on a good day. The rover’s drill—able to poke holes in multiple locations—will go deep into the Martian underground, as much as two meters (six-and-a-half feet).

“We’re opening the third dimension of Mars,” says Vago.

Within that third dimension, scientists expect to discover organic molecules. Though not alive themselves, organics are carbon-based, a prerequisite for life as we know it. Identifying actual biosignatures could indicate—not confirm, but indicate—”a possible life presence on Mars,” says Vago.

Organics have already been detected in Martian rocks. But what’s on or near the surface is likely compromised, ravaged by cosmic radiation. The drill will take samples less tainted. “We want to see,” Vago says, “if the preservation of organic molecules improves with depth.” Inside the rover, a mini-laboratory will study the samples and send the data back to Earth.

Vago is cautiously optimistic the rover will locate the biosignatures (“I give it 50-50,” he says). But ExoMars is unlikely to confirm life. Discerning that requires more missions. “Eventually we will bring samples back to Earth,” he says, “and analyze the heck out of them.”

If life is ever found, no one anticipates anything fancy. Scientists predict only the primordial, microorganisms at most. Martian guppies, alien alligators, or fossils of Flipper are not expected. “Nothing that would walk or slither around,” Vago says.

But even bacteria, existing today or long-extinct, would be a spectacular discovery. Extraterrestrial life so close—residing on the planet next door—implies life is abundant throughout the galaxy.

Could Mars be alive today? “I think the chances are rather high,” speculates Vago. Just go way deep, far more than the ExoMars drill will go, and look for liquid water; it might be a kilometer or two down (roughly a mile, give or take). Life on Earth prospers at those depths and then some. “We have a lot of microorganisms in total darkness here, munching away on minerals,” says Vago. “If the water’s there, why not?”

The drill will take samples less polluted. “We wish to see,” Vago states, “if the conservation of natural particles enhances with depth.” Inside the rover, a mini-laboratory will study the samples and send out the information back to Earth.

Vago is carefully positive the rover will find the biosignatures (” I provide it 50-50,” he states). However ExoMars is not likely to verify life. Critical that needs more objectives. “Ultimately we will bring samples back to Earth,” he states, “and evaluate the heck out of them.”

If life is ever discovered, nobody expects anything elegant. Researchers forecast just the primitive, bacteria at a lot of. Martian guppies, alien alligators, or fossils of Flipper are not anticipated. “Absolutely nothing that would stroll or wriggle around,” Vago states.

However even germs, existing today or long-extinct, would be an amazing discovery. Extraterrestrial life so close– living on earth next door– indicates life is plentiful throughout the galaxy

Could Mars live today? “I believe the opportunities are rather high,” hypothesizes Vago. Simply go way deep, even more than the ExoMars drill will go, and search for liquid water; it may be a kilometer or more down (approximately a mile, provide or take). Life in the world flourishes at those depths and after that some. ” We have a great deal of bacteria in overall darkness here, chomping away on minerals,” states Vago. ” If the water’s there, why not?”
