TEMPO.CO, Jakarta – On November 27 at 14:54 (EST) or 02:54 in the morning, NASA's mission check confirmed that the InSight vehicle had safely reached the surface of the planet, following a tense movement which left NASA engineers perched on the edge of their seats, reported Space. November 27, 2018.

InSight reaches the Martian atmosphere at a speed of 12,300 km / h (19,795 km / h). Within minutes, the fallen vehicle quickly deployed the parachute, removed its heat shield and launched 12 engines to slow down the last part of the landing, before landing on Mars.
After this extraordinary landing, InSight is immediately put to work. "Ten seconds after the landing, the InSight instrument was involved in the first mission: send signals directly to the Earth and take pictures of the landing sites," Jim told Green Science Green, chief scientist of NASA.
At 15:03, ET, NASA reported the first "beep" from InSight, which confirmed that the LG was going well. "InSight is in normal mode and presents no problem," said Rob Manning, NASA's system engineer, during the live broadcast.
And minutes after the landing, NASA had already had the first view of Mars through one of InSight's "eyes," when the wide-angle camera captured a reddish floor plate in front of the vehicle. The land seems without stones. "The black dots on the image are dust grains stuck on the lens cache," NASA officials explained during a live broadcast.
One of the first tasks of InSight on Mars has been to prepare its resources. "The first minute on Mars is fully supported by batteries because the solar panels attached to the Space Shuttle have been thrown out before the landing of InSight," Green said.
"InSight batteries can power the vehicle up to 16 hours with a single charge, but nevertheless, InSight needs to have its own solar power and run – or its life on Mars will be very, very short," Green said.
"About 16 minutes after landing, the time is enough to clean up the dust, and then the solar panels should develop without additional instructions from the Earth," Green said.
"When I saw the battery voltage rise again and the technical data was 100%, I knew we had a mission," he said.
Once the solar panel is activated, InSight will take more photos and prepare the rest of the instrument. This vehicle is equipped with two cameras: a wide-angle camera placed under the points of the body and another camera mounted on the InSight arm, which NASA engineers will use to check what is happening on the vehicle.
After confirming that the vehicle was in good condition, mission controllers could begin deploying seismometers (SEIS), which would measure "earthquakes". As soon as the SEIS instrument was installed, InSight would ask the researchers to heat HP3, which would measure the temperature of Mars.
InSight updates will be transmitted via ultra-high frequency (UHF) signals to satellites in orbit, where they will store data and transmit it to the Earth.
"However, there are still several weeks of preparation work for InSight – a slow and methodical process – that should last at least several months until 2019, before the start of the real scientific mission to Mars," added Green. .
