7 things to know about the Mars 2020 Perseverance Rover mission – Times Now

In less than a month, NASA expects to launch the Mars 2020 Perseverance Mission from Cape Canaveral, Florida. Loaded with scientific instruments, advanced computational capabilities for landing, and other new systems, the Perseverance rover is the largest, heaviest, most sophisticated vehicle NASA has ever sent to the Red Planet.

“Perseverance sets a new bar for our ambitions at Mars. We will get closer than ever before to answer some of science’s longest-standing questions about the Red Planet, including whether life ever arose there,” said Lori Glaze, planetary science director at NASA Headquarters in Washington.

What drives Perseverance’s mission and what will it do at the Red Planet? Here are seven things to know:

1. The Perseverance rover draws on the NASA — and scientific — a spirit of overcoming challenges.

The rover has a tough mission. Not only does it have to land on a treacherous planet, but it also has to work on its science goals: searching for signs of ancient microbial life, characterizing the planet’s geology and climate, collecting carefully selected rock and sediment samples for a future return to Earth, and paving the way for human exploration beyond the Moon.

These activities epitomize why NASA chose the name Perseverance from among the 28,000 essays submitted during the “Name the Rover” contest. Because of the coronavirus pandemic, the months leading up to the launch, in particular, have required creative problem solving, teamwork, and determination.

“Building this incredibly sophisticated rover has been the hardest thing I’ve ever been a part of as an engineer,” said Ray Baker, the mission’s flight system manager at NASA’s Jet Propulsion Laboratory in Southern California.

“While coronavirus added significant challenges and logistics, the team has shown great determination and diligence to build a rover we can be proud to send to Mars. We can’t wait to see the many years of dedication pay off at the launch pad,” added Baker.

2. Perseverance builds on the lessons of other Mars rovers.

NASA’s modest first rover — Sojourner — demonstrated in 1997 that a robot could rove on the Red Planet. Spirit and Opportunity, which landed in 2004, found evidence that the planet once hosted running water before becoming a frozen desert.

Curiosity, which has been exploring Mars since 2012, discovered that its landing site, Gale Crater, was home to of a lake billions of years ago, with an environment that could have supported microbial life.

Perseverance aims to take the next step, seeking, as a primary goal, to answer one of the key questions of astrobiology: Are there any signs that life once existed on Mars?

3. The rover will be landing in a place with high potential for finding signs of past microbial life.

Jezero Crater is 28 miles (45 kilometres) wide and sits on the western edge of Isidis Planitia, a giant basin just north of the Martian equator dug out long ago when a space rock hit the surface. Sometime between 3 billion and 4 billion years ago at Jezero, a river flowed into a body of water the size of Lake Tahoe.

“The science team has had many discussions internally and externally about where the next Mars rover should go,” said Ken Farley, the mission’s project scientist, based at Caltech in Pasadena.

“We ultimately chose Jezero Crater because it is such a promising location for finding organic molecules and other potential signs of microbial life,” added Farley.
