Here's what the Perseverance rover will do now

NASA's Perseverance rover just landed on Mars after leaving Earth more than six months ago.

Now that the rover is on the Red Planet, the work begins.

Here's what it will do:

  • The rover will explore Jezero Crater: The crater is the site of an ancient lake that existed 3.9 billion years ago. The rover will search for microfossils in the rocks and soil there.
  • It will relay images from Mars: Perseverance will capture images of its surroundings and send them back, unfold its "head" and take more pictures while going through some health checkups with engineers. Teams on Earth will go through a month of inspections, software downloads and preparations for roving.
  • The rover will drop a helicopter on Mars: Over a process that takes about 10 days, the rover will drop a helicopter, called Ingenuity, on the surface of Mars and roll away from it. The little 4-pound helicopter will have to survive frigid nights, keep itself warm and charge itself using solar panels. Then, it will be ready for its first flight, which will last about 20 seconds.
  • It will search for evidence of ancient life: Perseverance will search for evidence of ancient life and study Mars' climate and geology and collect samples that will eventually be returned to Earth by the 2030s.
  • Perseverance will record sound: It will be the first recordings of sound on the Red Planet.

Watch the NASA control room erupt the moment Perseverance landed

Perseverance, NASA's most sophisticated rover to date, just landed on Mars.

"When we put our arms together and our hands together and our brains together, we can succeed. This is what NASA does. This is what we can do as a country, on all of the problems we have, we need to work together to do these kinds of things and make success happen," Rob Manning, NASA Jet Propulsion Laboratory chief engineer and landing veteran, said on NASA TV of today's accomplishment.

The moment was a culmination of years of preparation for NASA scientists across the country.

Watch the moment inside the NASA control center in Pasadena, California:

Retired NASA astronaut: Space exploration "directly benefits our ability to survive all the crises that might come at us"

Retired NASA astronaut Ron Garan said the Perseverance rover landing on Mars is significant because "these are the baby steps of exploring our whole solar system."

"Really everything we do in space directly benefits life on Earth," Garan told CNN's Brooke Baldwin.

"It directly benefits our ability to survive all the crises that might come at us, whether that's super volcanic eruptions, global warming. Whatever the case is, a better understanding of how planetary science works, how planets function, and the life cycle of planets is going to help us here on Earth immensely. And it's also going to help us understand our place in the universe," he said.

Garan said the rover looking into why there isn't life on Mars now is just as important as looking for signs of life.

"Imagine if we see evidence that there was once life on Mars. I mean, that would be amazing in itself. But to me, the other part of that is, we'd want to know why there's not life there now. We would want to know why a planet that used to have water and used to potentially be able to support life no longer does. And that has incredible implications for our own climate study here on Earth," Garan said.

This is the first image Perseverance sent from Mars

Just minutes after landing on Mars, NASA's Perseverance rover beamed back this image to Earth. It is the first of many the rover will send while it's on its mission on the planet.

NASA's rover sends its first tweet after landing

So, Perseverance isn't actually tweeting from Mars, per se, but humans back at NASA are.

Here's what the account tweeted shortly after landing:

JUST IN: Perseverance rover has safely landed on Mars

The Perseverance rover just became NASA's fifth rover to safely land on the surface of Mars after surviving the "seven minutes of terror."

This is the most sophisticated rover the agency has ever sent to the Red Planet. It will gather data and look for signs of ancient life in a crater that once contained a lake about 3.9 billion years ago.

Perseverance's parachute has just deployed, and it has slowed its speed. It's very close to the surface.

The "7 minutes of terror" have begun

Perseverance has just started what NASA refers to as the "seven minutes of terror." This is when the rover essentially has to land itself on Mars with no help from NASA, due to a one-way 11 minute time-delay.

The ground teams tell the spacecraft when to begin EDL (entry, descent and landing) and the spacecraft takes over from there — and mission control begins an agonizing wait.

The spacecraft hits the top of the Martian atmosphere moving at 12,000 miles per hour and has to slow down to zero miles per hour seven minutes later when the rover softly lands on the surface.

Here's a look at what happens during the final moments:

The cruise stage of Perseverance's journey has ended, and it has arrived at the Red Planet. This means the spacecraft will need to slam on the brakes to slow down from a speed of around 12,000 miles per hour.

Entry, descent and landing will begin soon.
