Mars landing: NASA landing InSight to study an unknown interior of the planet



NASA Jet Propulsion Laboratory missions control applauded celebrations and denied touches. Landing was seen all over the world and was also broadcast live on the New York Times Square market on the Nasdaq Stock Market.

At the NASA press conference in the post-landing conference, astronauts congratulated the Space Station at the International Space Station and said they were watching "gotosebumps".

"Today, the eighth season of mankind's history has been successful in Mars," said Jim Bridenstine, NASA Administrator. "InSight will explore the interior of Mars and give us valuable science to send astronauts to the Moon and then prepare for Mars. We imagine ourselves in the invention of America and our international partners, and it works as a dedication and testament." The sustainability of our team, the best NASA has just arrived and will soon be. "

Bridenstine said Mike Pence's vice president congratulated the whole group.

InSight or Indoor Analysis, Seismic Research, Geodesy and Heat Transport, will explore a part of Mars that we know less: its deep interior. It was launched on May 5. InSight has been investigating the interior for two years, where the buildings below the planet's surface were registered in history.

To reach Mars, InSight made 301,223,981 kilometers in space at a speed of 6,200 kilometers per hour, with two satellite cores. Marcon's suitcase size spaceship, the first cube satellites to fly in deep spaces. MarCO shared data on InSight when landing into Martian's atmosphere.

"Since 1965 we have been studying Mars in orbit and surface to know its weather, atmosphere, geology and surface chemistry," said Lori Glaze, director of NASA's Science Director of Planetary Science Division. "Now, finally, we will explore inside Mars and deepen our understanding of our land neighbor. NASA wants to explore the solar system for human explorers."

NASA's InSight Mars Captivator captured the image of the territory using a landed instrument context camera.

The first image taken by InSight still covers the cover of the lens and will be removed this week. The black clothes are dust, and there is a rock on the left plane. At the right is the Cape Plane.

Landslide

InSight steals robotic through landing. Landing is very difficult to maneuver. NASA engineers do not call anything "frightened for seven minutes". In less time than a tough egg, InSight lowered to 12,300 mph at 5 mph, before landing on Mars, according to NASA.

"While most of the people are enjoying Thanksgiving and their friends, InSight team was busy making landings last Monday," said Tom Hoffman JPL, InSight's project manager. "Mars Landing is a difficult task, and it takes a lot of personal sacrifices, such as the lack of traditional Thanksgiving, but InSight is a great success."

Countdown to Mars: Seven-minute sweat sweat from NASA & # 39;

40% of the missions sent to Planetary Bodies succeeded. Part of it is Martian's thin atmosphere, that is, it's just 1% of the Earth, so there's nothing left to stop trying on land.

Similar to the Phoenix spacecraft, InSight absorbed the shock that touched the surface of the three-legged suspension of the drops of the atmosphere during the fall of the atmosphere and the parachute and retro rockets.

But the engineers prepared a spacecraft to land on a windshield.

20 minutes before landing, InSight, from one cruise to another, made it easier for Mars to become an atmospheric access point.

At 2:47 p.m. ET began its entry, descent and landing phase, and InSight was darkened to 12,300 mph. The heater's heat shield coat reached the 2,700 degrees Fahrenheit two minutes later. That is, the heat was a hot casualty signal that caused a fall.

Then, when the paragliding was opened, the clover separated by the heat shield turned three legs and radar on the ground. After obtaining a radar signal, he separates the other casing and parachute, and he knows again his descent engine.

In a ballet-like fashion, InSight made a twist on gravity before touching it to the ground before placing it in the right position. It slowed down to 5 mph. Then he touched 2:54. ET.

Less than 3 hours ET, InSight sent a signal to scientists alive and well-known on Earth.

"The Martian atmosphere has reached 12,300 mph, and the entire sequence is only 6 minutes long," Hoffman said. "Over the course of a short time, InSight had to perform ten operations autonomously and make better and all expressions, that is, specifically our spacecraft."

Bruce Banerdt JPL, the InSight chief investigator, said: "It takes more than a decade to bring the concept of InSight to a spacecraft near Mars, and even this is the first inspiration for this mission. After landing, be patient We need science to start. "

What happens next?

InSight's two-year science mission will not begin immediately. It will last two or three months for the robotic arm to put on missions. Meanwhile, mission scientists can see from a territorial viewpoint and monitor the environment. Science data are not expected until March.

Later on Monday, they should be able to confirm that mission scientists have dismantled solar space arrays.

"We are solar energy, therefore, the extraction and exploitation of the matrix," said Hoffman. "With energy-supplying matrices, we need to start cool scientific operations. We want to do a lot of research into what is running".

InSight, Elysium Planitia called "the largest parking lots for astronomers". In fact, it does not work on the surface, the landing area was a determining factor. This place is open, flat, safe and boring, which scientists want a mission every two years.

NASA chooses an ancient crater as the next Mars landing site

InSight will open its solar panels and army robots and will explore the entire planet from its parking lot. It is a Martianian equator, with a solid set of ground throughout the year.

InSight's geophysical instrument suite has a doctor bag, and Mars gives its first "check". Together, the instruments will measure the signs of Mars's life, such as pulse, temperature and reflexes, including inner activity and the wobble of the planet, the sun and its satellites.

These tools investigate internal structural seismic structures when they are exposed on the surface of Mars's Heat Flow and Physical Properties Package and use radio stations to search for radiators and Rotation and Internal Frame Experiments on planet Earth. the core of the planet

"The landing was exciting, but I hope to drill," said Banerd. "When the first images go down, our engineering and science teams will start on the ground to begin planning our expansion of science tools. In two or three months, weapons will open the mission's main scientific instruments, the Seismic Internal Experiments Framework (SEIS) and the Heat Flow and physical properties package (HP3) tools ".

In the meantime, MarCO's mission is over. But cube satellites can survive the camera in deep spaces.

"Each Mars landing is horrible, but now InSight safely with the surface, we will get the kind of Mars science," said JPL director Michael Watkins. "The experimental MarCO CubeSats has opened a new door of the planet's smaller spacecraft, with the success of these two missions, hundreds of talented engineers and scientists are paying homage to their genius and work."
