InSight Mars Nasa editor touches Mars on Science

After a seven-month trip, 300 miles from a mile, Mars InSight Nasa's sight has reached its destination and touches close to the red planet's glass.

The thief came to rest on the dusty surface shortly before 8pm GMT on Monday after a nail piece that began when the spacecraft entered the Mediterranean atmosphere at 12,300mya and later later records with the setter in settling on the ground, its ditches are quiet.

Mission scientists were abducted, abducted and destroyed at Nasa's Lab Propulsion Laboratory in California when the real estate was signaling to reach the planet. "It was intense, you could feel the emotion," said Jim Bridenstine, the administrator of Nasa. "Which day to Nasa."

InSight cleaning areas, the Elysium Planitia, are one of the most boring places in the foreign world: a spacious, smooth plaque, the United States space agency calls "the largest car park on the Mars ". But a characteristic landscape, and I hope, quietly, exactly what InSight needs for its mission to map inside the planet.

"This is the first chance we look deep inside another planet, look at the structure and discover why it ends in the way it did," said Rain Irshad, leader of the autonomous systems group at RAL Space in Oxfordshire, and one of several UK Scientists who worked on InSight instruments.

The $ 814m (£ 633m) lander will draw on a series of instruments to study the composition and core dimensions, mantle and planet crest. Based on that data, scientists are hoping to learn how Mars – and other rocky worlds – formed at the bottom of the solar system 4.6 billion years ago.

Sending a messenger to Mars, either to land, orbit or fly past, is a dangerous business: only 40% of the flights have been successful. Nasa is the only space agency that has taken off Marsh's wharf, recently in 2012 when the curiosity cracked to the surface with a "hover" air crane. In 2016, the European Space Agency tried to put itself on a launcher on Mars, but the Schiaparelli search closed its retro rockets too soon and was cut into the ground.

The InSight lander had to perform smoothly to touch safely. Shortly after he arrived at the Martian tenaneous atmosphere, he released a parachute, then throwing off his heater and breaking off-impellers to slow down. He confirmed that InSight survived what Nasa calls "the seven minutes of terrorism" and to touch it down to Earth through cube satellites that pointed to the destination to & # 39; w destination.

InSight, who stands for Internal Audit Using Seismic Investigations, Geodesi and Transport, will use three tools to study Mars. A seismometer used by a robot arm will act as an ear to the floor and listen to cruelty generated when slippery rock faces slide together on geological deficiency lines. These pressure waves bounce around the planet, and they can reveal essential information about its structure.

Mission scientists are expecting InSight to record anything from a dozen to 100 Pictures of a size of 3.5 or more over the two-year mission of the heater. The seismometer is so sensitive that it can find vibrations less than our width.

"The most important question is whether Mars is active in seismic," said Neil Bowles, a planetary scientist at Oxford University, who worked on the spacecraft. "We have indirect evidence for shaking on the surface, for example by looking at boulders that turn down slopes in orbit images, but InSight will be the first mission to install a seismometer directly on the surface of Mars.

"The Marsquakes Bill will provide information about the Mars structure and hope to reveal more about how the planet was formed. Why is Mars smaller and lower than Earth and Venus? It suggests that the formation and evolution Mars is somehow different from the Earth's process or some process in the early solar system and prevents Mars from growing more. "

Another instrument, heat auditor, will fall 5m into the ground and measure the rate of heat rising through the planet. In a third experiment, mission scientists will use the antenna on the banks to track their site with such accuracy that they can deduct how much Mars carries on its axis. How much wobble reflects the size of the planet's core and it is melting or firm.

The yellow rotation of the Earth's iron iron creates the magnetic field that transmits life from harmful radiation, and helps to prevent the high energy particles in the solar wind from being removed from the air. At some point in its history, Mars lost its magnetic field, and much of its atmosphere, causing the temperature to discharge and expose the surface to intense radiation. InSight can help explain why, says Irshad.

"Are there conditions under the surface that could have led life to go there to survive?" He said. "If he had returned under the surface, future trips might have it there."
