According to foreign media CNET, it is only a few weeks before NASA's willpower Rover landed on the surface of Mars. Willpower will land in Jezero crater on February 18, becoming the first man-made object to land on the surface of Mars since the Mars insight Lander in 2018 and the first Rover since curiosity landed on Mars in 2012.But willpower carries more audio-visual equipment than its predecessors to capture parts of the mission's critical entry, descent and landing (EDL) phase.
A camera mounted on the rover's rear shell, facing up, will be able to capture the view of parachutes that will unfold during the descent to slow down the landing speed of willpower. Below this is a downward pointing camera on the downgrading, which can further slow down the rover and orient it for landing.
Finally, the rover itself is equipped with a camera and microphone. Overall, the technology should provide scientists with the most detailed images and audio of landing on Mars so far.
"We will be able to see ourselves landing on another planet for the first time," Lori glaze, head of planetary science at NASA's mission agency, told reporters in a briefing on Wednesday. The entire EDL phase will only last about seven minutes, but Allen Chen, head of EDL, said it was "the most critical and dangerous part of the mission.".
Willpower will hit the Martian atmosphere at nearly 12000 mph (19312 km / h) and will begin to slow down thereafter. A 70 foot (21 meter) diameter parachute will be deployed to further slow it down. After that, its heat shield will be released and the radar will be activated to help it locate itself.
After landing, however, it will be able to send images back to earth using the Mars Reconnaissance Orbiter (MRO). Allen Chen estimated that shortly after landing, at least some low resolution images of the environment around the willpower could be seen. But scientists may have to wait a few days before they can see more images and audio to give a full picture of the landing process.
"I don't think covid can stop our excitement and our desire to try." Said Matt Wallace, deputy project manager. "Once we put this thing safely on the ground, you'll see a lot of happy people anyway."
