NASA shares new images to show the "seven minutes of terror" of willpower

According to foreign media reports,"Willpower" Mars rover landed safely yesterday, but only carried out a series of complex operations when it was descending through the atmosphere at a high speed, which was called "seven minutes of terror" by the team.NASA has just shared a picture that shows how much easier it is to understand the horror of a Mars rover hanging from a "jet pack" over the Martian landscape.


This image is one of the first images of the willpower rover; black and white photos of its navigation camera appear almost immediately after landing, but this is the first time we have seen the Rover from this angle. The image was taken by a camera on the downgrading or "jet pack," a rocket powered descent module that takes over once the vehicle decelerates sufficiently through atmospheric friction and its parachute. Once the thermal shield is thrown out, willpower scans the terrain for a safe landing site. Once it is found, the job of jet pack is to help it fly there.


When the willpower is about 70 feet from the landing site, the jetpack deploys "overhead cranes", which are a group of cables that can lower the Rover from a distance to the ground, safely allowing the jetpack to rocket to the far landing site.


However, the first person view may not be the most impressive picture of the descent. Shortly after the launch, NASA released a stunning image from the Mars Reconnaissance Orbiter (MRO), which successfully captured the descent of willpower under its parachute.


At the time of taking this picture, the MRO was 700 km away and travelling at a speed of more than 3 km / s. "The extremely long-distance and high-speed travel of the two spacecraft is a challenging condition, which requires precise timing. The Mars Reconnaissance Orbiter should not only rush up, but also roll violently to the left, so that the willpower can be seen by HiRISE at the right time." NASA wrote in the photo description.

Once NASA has collected enough images from willpower, we may soon see a more complete picture of "seven minutes of terror.".
