NASA Presents Dramatic Mars Landing Video, Releases Images | Scientific and technological news

NASA claims the Perseverance videos provide a “ treasure trove ” of details about the alien world.

NASA unveiled the first video and colorful images of the Perseverance landing on Mars Monday, accompanied by the first sound recording of the Martian surface.

The video, released at a press conference, showed the spacecraft chasing red dirt as it landed on the surface of Mars on February 18, following a landing sequence that personnel from the NASA described it as going as planned – including a small amount of back-and-forth. and engine throttling.

The rover roamed space for nearly seven months, traveling 472 million km (293 million miles) before landing safely on Mars at 19,000 km / h (12,000 mph).

Al Chen, a systems engineer in the Entry, Descent and Landing Systems and Advanced Technologies group at NASA’s Jet Propulsion Laboratory, said “we could spend the whole day looking” at the footage.

Chen said the data from Mars provides a “rich treasure trove” of images and sounds from the surface of the Red Planet.

Viewers were encouraged to watch the videos at slow speeds to observe these details.

The sounds recorded by the rover presented the desolate soundscape of the planet, with a strong gust of Martian wind and nothing else.

The Perseverance is NASA’s fifth science rover on Mars and is the most advanced astrobiology laboratory never sent to an alien planet. There have been 49 missions to Mars since 1960 by nine nations.

The rover and the accompanying program cost $ 2.7 billion and took two years to develop.

NASA is hoping to find possible evidence of rudimentary life, including signs of microbes, in ancient sediments collected from Martian rock by Perseverance.

The specimens are said to be the first collected by humans on an alien planet.

NASA has planned two more trips to Mars to retrieve the specimens and return them to Earth. These future trips are planned for the next decade.

Justin Maki, a JPL scientist who has worked on the rover’s five missions to Mars, told the press conference that he knows 2020 is a tough year for the world and that he hopes the images from Perseverance , which are available to the public, would help relieve the pain.

“We are so happy and proud… we hope these images will help brighten up people’s day.”
