Perseverance sends back the first batch of Mars images, some have never seen

On February 18th, NASA’s Perseverance probe successfully landed on Mars. Now it has started to work and has returned the first batch of “unbelievable” images.

For example, a photo taken by the “Sky Crane” system recorded the moment before Perseverance landed on the surface of Mars. After the Perseverance probe entered the Martian atmosphere, the “sky crane” system used thrusters to slow it down and land it gently on the surface of Mars.

Such pictures have never been taken before. Although the Curiosity rover also used the “air crane” system to land on Mars, the system on the Curiosity did not have a camera. This still image is part of NASA’s upcoming video (the first video shot on Mars).

“As scientists, we are used to engineers showing us the animation of the detector—at first I thought this was the animation of the detector.” NASA Jet Propulsion Laboratory (JPL) Perseverance team member Katie Stack Morgan said, “I glanced at it again before I realized,’That’s a real lunar rover!'”

After landing, Perseverance took a photo of its right front wheel. “We do see the situation under the wheels now,” said Hallie Abarca, a member of the JPL Perseverance team.

The probe landed on the Jezero crater, which was once a lake bed. The rock under the wheel is about 3.6 billion to 3.8 billion years old, and may be sediments of ancient lakes. Judging from the photos, scientists’ first impression is that they may be volcanic rocks, but this requires further research.

There is also a picture showing Jezero The desolate scene of the crater, with a ridge in the distance. This is the highest resolution photo ever taken on the surface of Mars. Soon after, Perseverance will enter the crater and begin exploring.
