California: NASA’s rover to Mars has landed on Mars without any problems. At 1:55 a.m. Pakistan time, it touched the surface of Mars.
At 1:45 a.m. Pakistani time, the spacecraft reached the cruise stage. At 1:50 a.m., it entered the Martian atmosphere.
After that, it had to go through the biggest obstacle in the Martian atmosphere, ie the highest temperature, and at 1:50 a.m., it also passed this stage. The next step was to open the parachute. Meanwhile, there was silence in the NASA control room and the experts kept watching all the stages.
At 1:53 a.m., he opened his parachute, a milestone, and the control room resounded with applause. In the next few seconds the heating shield disintegrated. Only then did the radar lock his destination where he was to land. During this time, it turned to Mars at a velocity of 90 meters per second.
He then inspected the surface of Mars, separated its rear shield, and pushed the ship to the bottom. The whole process was completed at 1:55 p.m.
In the 11th operation, the rover detached from the air crane and at one o’clock 56 minutes the spacecraft landed on the surface of Mars, which was named Touchdown.
At 1:58 a.m. Pakistani time, the Preservation sent the first image from a hazard camera after touching the Martian surface. This image was taken while landing on Mars but was received on Earth a few minutes later.
Seven minutes between hope and despair
Last Christmas, NASA released a trailer for the space mission Preservation. In this trailer, all the important stages of the landing of the Preservation Mars spacecraft were explained.
NASA insiders called these stages “seven minutes of fear,” meaning seven minutes of terror. The slightest mistake during this time was enough to destroy the whole project.
The first of the 12 stages was about the spacecraft entering Martian space and the last stage was touchdown. But on one occasion, Mars had to endure the intense heat generated by air friction. Because that heat was enough to burn the entire circuit of the fragile spacecraft. This step was the most important for the NASA control room.
Space Biology and Helicopters
This time the Preservation Mission is specifically designed for astronomical research. Its special instruments will try to find any old microorganisms or organelles in the red soil of Mars. It will explore some of the oldest traces of the Martian climate and eventually pave the way for human adventures.
Presence has a two-year mission, but on Mars it will be one year. According to a NASA female expert, the rover is equipped with state-of-the-art equipment and its main goal is to consider the possibility of human survival and survival on Mars. But for the first time in Presence, a helicopter has been sent to Mars. Thus, for the first time in human history, a helicopter will fly in Martian space and survey the surface of Mars slightly faster than a slow-moving spacecraft.
Although the helicopter will not be used in research, it will pave the way for further Mars projects. The high definition camera on it will send us more amazing pictures of Mars.
It should be noted that this is the first NASA project that will also collect soil and rock samples from the surface of Mars and in the future they will be brought to Earth.
