NASA Planning to Bring Pieces of Mars Back to Earth

LA CANADA-FLINTRIDGE (CNS) - NASA Administrator Jim Bridenstine has unveiled a $25.2 billion plan that would send astronauts back to the moon by 2024 as part of the space agency's Artemis program, and ultimately prepare for a crewed mission to the Red Planet.

The White House's budget request for NASA earmarks more than $3.3 billion for a lunar landing system for humans -- the first direct funding for such a system since the Apollo missions of the 1960s and 70s, the Los Angeles Times reported.

The budget for the 2021 fiscal year would also provide nearly $2.7 billion for planetary science, including $233 million to develop the Mars Sample Return mission. That marks the official green light for a long-awaited effort to collect samples of Martian rocks and soil and send them back to Earth for analysis.

The Mars 2020 rover, set for launch this summer, includes equipment to seal the samples in narrow tubes and leave them in the vicinity of Jezero Crater until a smaller rover from the Mars Sample Return mission rolls by to pick them up and hand them over to a lander. Then the lander will pack them into a rocket, which will blast off the Martian surface.

If successful, the mission would carry out the first rocket launch on a planet other than Earth.

“This sample return is such a critical element because it's the first round-trip to that other planet,” said Thomas Zurbuchen, associate administrator for NASA*s Science Mission Directorate, according to The Times.

The announcement was welcomed by scientists

“This is everything we've been hoping for,” said Brian Muirhead, chief architect for the Mars Sample Return mission at the Jet Propulsion Laboratory in La Canada Flintridge, which is managing the campaign, The Times reported.

Although Mars is now a dry, cold landscape with a barely-there atmosphere, billions of years ago it may have looked much like Earth, with puffy clouds and lakes of liquid water.

Satellite missions have documented what look like ancient riverbeds and deltas on the planet's surface, and NASA rovers have found telltale chemicals that indicate Mars once had habitable, watery environments.

But it's one thing to be hospitable to living things, and quite another to know whether they actually existed. In order to search for biosignatures of past or present life, scientists need tools that are far more sophisticated than anything they can put on a spacecraft, said Jonathan Lunine, a planetary scientist at Cornell University.

Bringing samples back to Earth, where they can be studied with state- of-the-art instruments, “will be an enormous advance in terms of the science of Mars and ... [the] possibility that it might have even had life at some point,” Lunine said according to The Times.
