TUCSON, Arizona – A new satellite has just completed a dangerous high-speed trip to Mars and made a safe landing.
A project from the University of Arizona helped choose the parking spot for
Landing Mars InSight
. The new probe will work to learn what is well below the Martian surface.
They had many reasons to celebrate at NASA's Jet Propulsion Lab in California.
They guided the InSight Lander over millions of kilometers and programmed it to go from over 12,000 kilometers to the hour to a smooth and safe landing in just under seven minutes.
Professor Shane Byrne, from the University of Arizona, attended the successful landing. He knows that AU has contributed to his success.
UA is a world leader in planetary science. He led his own mission on Mars, the
Phoenix Mars
LG
. In just one week
The UA probe of Osiris Rex
will arrive at the asteroid Bennu and begin to prepare to bring back an asteroid sample on Earth.
Shane Byrne works with
HiRise, the powerful camera
designed and managed by the University of Arizona
HiRise is in orbit around Mars and has been studying its surface for 12 years. According to Byrne, the HiRise images in orbit helped mission planners choose a safe place to land, as well as the number of boulders on the surface, as they do not fall over a rock; To do this, we take regular photos but also stereo images from two different angles, which allows us to get an idea of the roughness of the topography of the surface. "
HiRise's role in site selection should help InSight find the facts for which it came. The site is a hard and stable surface that will help InSight's sensitive seismographs measure earthquakes on Mars.
"And by looking at how fast these seismic radio waves arrive for different types of waves, you can probe the inside of the surface and determine how fast the seismic waves can propagate to different depths," Byrne explains. "This information tells you pretty much how the planet is made up of the inside."
And scientists say that the data collected by InSight could teach us how other planets are formed, believing that Mars could be a model of how other rocky planets meet.
