NASA InSight lander's long journey to Mars

Technicians and engineers inspect the heat shield for the InSight spacecraft at Vandenberg Air Force Base in California.

After a 300-million-mile journey that lasted more than six months, NASA's Mars Insight lander has touched down on the red planet. It is NASA’s first landing on Mars since the space agency’s Curiosity rover in 2012. 

The planned landing site for NASA's InSight lander is in the Elysium Planitia region of Mars.

The landing ellipse on this map covers an area within which the spacecraft has about a 99 percent chance of landing when targeted for the center of the ellipse. It is about 81 miles long and about 17 miles wide.

The mobile service tower is rolled back to reveal the United Launch Alliance Atlas V rocket with NASA's InSight spacecraft onboard on May 4, 2018.

The Atlas V rocket carrying the Mars InSight probe lights up the sky, as seen from the San Gabriel Mountains, more than 100 miles away, on May 5.

Ensconced inside its heat-protecting “aeroshell” capsule, the 800-pound lander descended 70 miles through the thin Martian atmosphere. 

A supersonic parachute and a series of descent engines slowed the spacecraft before it touched down on shock-absorbing legs.

Insight won’t be able to move about on Mars. Instead, using a suite of instruments and a seven-foot-long robotic arm, it will drill up to 16 feet below the surface at its landing site.
