The newest robot, the rover, has wheeled down to inhabit Mars. Nasa’s multibillion-dollar robot has landed safely on the Martian surface after a 300 million mile journey to the planet. The engineer of the Perseverence crew, Swati Mohan, has confirmed the landing of Perseverance on Mars. The nuclear-powered Perseverance rover has made a swift through the thin Martian atmosphere and is captured through a video. The rover itself timed its motion for capturing its movement over the surface. By signalling to the Earth using the Mars Reconnaissance Orbiter, Perseverance confirmed its safe arrival to Mars and has sent its first photos of Mars.
The crux behind the mission
After the first photos from the surface has arrived at the Jet Propulsion Laboratory, the team started celebrating the moment. The deputy project manager of Perseverance, Jennifer Trosper, expressed a lot more to consider and go right for massive success.
The crux behind the scenes is to gather evidence of ancient life on the red planet, Mars. The rover’s mission is something ambitious for tracing out everything at Mars. The five rover’s mission is to search for the traces of long-dead Martian for its first billion years, which was wetter and warmer than what we see today of the planet.
Basically, scientists required evidence for ensuring if there are human traces on Mars to enable earthly living over the planet. It helps the scientists to gather samples of rocks that is pocketed by rover for sending them to the Earth. These samples of rocks can help ensure if the planet Mars was once a living planet.
The answer to the question, whether life existed on Mars can be revealed with the rock samples that the rover gathers. And not only getting samples, is the duty of Perseverance, the instruments embedded can find out water terrains that could be strong evidence of human existence.
A 300 million mile journey to another world
The day on which Perseverance was set to sail is July 30, 2020, and for seven literal months, it drifted through space. Inside the protective shell was the spacecraft that got tucked up like a bug inside. The rover’s six wheels were pulled inward, its arms were folded, and ingenuity, a small helicopter settled in a comfortable position.
During this time, the team of Jet Propulsion Laboratory tested the spacecraft by waking up and getting an audio clip through its onboard microphone. The scientists of the rover were thrilled to hear the sound of mechanical whirring spacecraft over space. For any spacecraft, the most crucial moment is its entry, descent and landing stage.
On February 18, the crucial stage started where it was a do or die situation of entry, descent and landing of the rover. As there is no partial credit given to any one of the stages, the scientists were eager to know the project’s success. In the pursue of the end of the drifting stage, the Perseverance started zooming the planet at 12100 miles per hour.
After the hit towards the Martian atmosphere, the drag slowed down its descent to below 1000 miles per hour. With this, the parachute equipped slowed down it to 200 miles per hour. The planet’s air is too thin, and hence a series of manoeuvre helped the rover slow down its descent.
With the help of a sky crane, Perseverance safely landed on Mars. The sky crane’s retrorocket helped the spacecraft further slow down the descent to 17 miles per hour. With nylon cables, the Perseverance slowed down and landed upon the surface. After this, the sky crane flew off to avoid complicating the rover’s task of surface operations.
The space agency has set out for capturing the audio and video. The six cameras embedded with the rover should have captured the entry, descent and landing of it if everything went well throughout. As a microphone is attached, the engineers could download the data and process it. NASA could release the visuals and sounds of the rover on the Martian surface.
What we see today had life on Mars.
Scientists with this research can unfold the truth that life existed on Mars. Though we see arid landscapes today, this was not the case billion years ago. Water flowed and got pooled on the surface that conveys the chances to thrive. With this rover, it is possible to unbox the reality that life can exist on the red planet after long years of dreaming of living amidst the stars.
