Intertlanetar space travel was held on Monday. NASA sailed InSight on Mars spacecraft to begin its two-year study of the core of our adjacent planet. This is the first MarsA landing Mars since the Son of Shame was touched in 2012.
After a 300 million mile trip, the landowner started around 2:54 pm ET and took this picture of a landing site. (There is a dust cover on the lens that is covered with debris, but you can continue to make the ground and the horizon on May. Ultimately, the dust cover will be removed and we will have pictures cleared by InSight.)
You can watch a live stream of NASA's mission in the video below.
And here's why the landing was so strange: Because the spacecraft was so far away, NASA mission scientists at the Jet Propulsion Laboratory in California did not have an InSight pilot. Several minutes are delayed from transmitting radio to the cleaner. And like the curious curiosity, InSight had to catch himself in just 6.5 minutes.
Now we have to wait a few hours for confirmation that InSight solar panels have opened.
Landing a robot spacecraft on Mars is not easy
It has a huge engineering sport to land on Mars, and not just because it is millions of miles away.
The challenge: Red Planet has almost the same gravity of the Earth, but differs from the Earth, it does not have a thick atmosphere to help slow down the spacecraft. InSight drew to the Martian atmosphere traveling for 12,300 mph, and within 6.5 minutes, he had to slow down to 5 mph to land.
The landing occurred in a few steps that were carefully programmed by NASA scientists. First, InSight apart from the "cruise period" of the mission. Here is the part of the art that's its iron from the Earth to Mars, and it was necessary for Insight to leave it behind in space.
Then Insight had to turn so his heat shield was stressed dead in the atmosphere, which began about 70 miles over the face of the planet.
He shielded that heat shield as it slows from 12,300 mph to 1,000 mph in just two minutes. Then, 10 miles above the surface, he saturated the heat shield and used a parachute. But the parachute was not enough to slow down the craft to accelerate landing.
This was the most boring: InSight had to catch himself, and he had to be ready for less than ideal conditions, such as a dust storm.
About a mile above Mars, InSight let the parachute enter some ditches. He had to move quickly not to reach the transported parachute.
Led by the radar, InSight used its ditches to slow down to a soft wharf. After landing, the repairers had to turn straight away. (If Insight was transported over the surface, it would not be charged back.)
InSight led to a Mars region of the name Elysium Planitia, large plain, flat, on the equator. The site was selected, in part, because InSight will run on solar power, and it would need to be close to the equator to have enough sunlight to continue to be powered for two years.
So what will InSight do there?
Now InSight has landed, it's given. It's not as ugly ashamed. And we do not need to move because it is not there to study the surface of Mars. InSight stands for "Internal Audit using Seismic Investigations, Geodesi and Transport," and is there to study the core of Mars. Basically a robot geologist. Using highly sensitive instruments, it will literally be able to feel seismic activity and the temperature of the planet, and record, for the first time, "Marsquakes".
"Every Marsquake would be a flash format that illuminates the inside structure of the planet," explained NASA. "When studying how seismic waves pass through different layers of the planet (the crust, the mantle and the core), scientists can deduct the depth of these layers and what they are & I do it. In this way, seismology is like taking X-ray within Mars. "
Insight will also take Mars temperature; The Heat Flow and Physical Property Project will hammer 16 feet down to the surface. The instrument will be able to determine how heat flows from Mars's surface to its surface, and helps scientists understand whether Earth and Mars pools are similarly formed.
All this is important to study because scientists want to better understand how rocky planets like Mars, Earth, and Venus form. Under the face of the Earth, we have a hot mantle to drain on which our landing (tectonic plates) float. Plate tectonics is responsible for many geological activity on Earth, generating the energy for earthquakes and volcanoes. But Mars does not have an active tectonic like ours.
Scientists are curious why a rocky planet such as the Earth is dynamic and dynamic, and why a rocky planet like Mars is so persistent. These insights may lead to a better understanding of why life is on Earth but not Mars.
