The NASA earthquake sensor, Insight's Earthquake, landed in a small corner of the Red Planet, and experts hope the spacecraft will work according to the plan, the US space agency announced on Friday.
The $ 993 million arrivator arrived at its goal, a lion plane named Elisium Planinia, for a two-year mission to better understand how the neighboring planet on Earth is formed.
"The vehicle is slightly tilted (about 4 degrees) in a shallow crater for dust and sand impacts known as" hollow, "the NASA statement said.
InSight was designed to work on an area with a slope of up to 15 degrees.
Therefore, experts hope that its two main instruments – the earthquake sensor and the scroll wheel for measuring heat below the surface – will work according to the plan.
"We could not be happier," said InSight Project Manager Tom Hoffman from the NASA laboratory for a dip laboratory.
"There are no places to land or run on Mars, so we are coming down to an area that is basically a large sand without large rocks to facilitate the deployment of the instruments and provide a great place for our mole to begin to bury."
The first pictures of the lander show only a few rocks in the vicinity, even more good news, because touching down near the rocky space would make the deployment of the solar arrays and instruments poor.
Better picture is expected in the coming days after InSight throws the dust of its two cameras.
"We look forward to photographs with a greater definition to confirm this preliminary assessment," said Bruce Bannert, chief inspector of InSight at NASA.
"If these few images – by covering the dust to reduce the resolution – are correct, it's good for the deployment of the instrument and for breaking the moths of our underwater heat experiment."
Safe on Mars, InSight breaks down its arrays and snaps some pictures
