How did Perseverance land on Mars ? Here's what you need to see

Agency- The first ever footage of Perseverance landing on Mars has been out. NASA, on their youtube channel has published the footage of spacecraft landing on Mars. 

 

"For those who wonder how you land on Mars – or why it is so difficult – or how cool it would be to do so – you need look no further,” said acting NASA Administrator Steve Jurczyk. “Perseverance is just getting started, and already has provided some of the most iconic visuals in space exploration history. It reinforces the remarkable level of engineering and precision that is required to build and fly a vehicle to the Red Planet.”

 

The six-wheeled robotic astrobiologist, the fifth rover the agency has landed on Mars, currently is undergoing an extensive checkout of all its systems and instruments.

 

“This video of Perseverance’s descent is the closest you can get to landing on Mars without putting on a pressure suit,” said Thomas Zurbuchen, NASA associate administrator for science. “It should become mandatory viewing for young women and men who not only want to explore other worlds and build the spacecraft that will take them there, but also want to be part of the diverse teams achieving all the audacious goals in our future.”

 

The world’s most intimate view of a Mars landing begins about 230 seconds after the spacecraft entered the Red Planet’s upper atmosphere at 12,500 mph (20,100 kph). The video opens in black, with the camera lens still covered within the parachute compartment.

 

Within less than a second, the spacecraft’s parachute deploys and transforms from a compressed 18-by-26 inch (46-by-66 centimeter) cylinder of nylon, Technora, and Kevlar into a fully inflated 70.5-foot-wide (21.5-meter-wide) canopy – the largest ever sent to Mars. The tens of thousands of pounds of force that the parachute generates in such a short period stresses both the parachute and the vehicle.

 

The footage ends with Perseverance’s aluminum wheels making contact with the surface at 1.61 mph (2.6 kph), and then pyrotechnically fired blades sever the cables connecting it to the still-hovering descent stage. The descent stage then climbs and accelerates away in the preplanned flyaway maneuver.

 

Five commercial off-the-shelf cameras located on three different spacecraft components collected the imagery. Two cameras on the back shell, which encapsulated the rover on its journey, took pictures of the parachute inflating. A camera on the descent stage provided a downward view – including the top of the rover – while two on the rover chassis offered both upward and downward perspectives.

 

A key objective of Perseverance's mission on Mars is astrobiology, including the search for signs of ancient microbial life. The rover will characterize the planet’s geology and past climate, pave the way for human exploration of the Red Planet, and be the first mission to collect and cache Martian rock and regolith.
