NASA detects largest meteor strikes on Mars through InSight, Orbiter missions

Two NASA spacecraft at Mars — one on the surface and the other in orbit — have recorded the biggest meteor strikes and impact craters yet.

The high-speed barrages last year sent seismic waves rippling thousands of miles across Mars, the first ever detected near the surface of another planet, and carved out craters nearly 150 meters across, scientists reported Thursday.

The larger of the two strikes churned out boulder-size slabs of ice, which may help researchers look for ways future astronauts can tap into Mars’ natural resources.

The Insight lander measured the seismic shocks, while the Mars Reconnaissance Orbiter provided stunning pictures of the resulting craters.

Participants addressing media during the press conference included: Lori Glaze, director of NASA's Planetary Science Division, NASA Headquarters; Bruce Banerdt, InSight principal investigator, NASA's Jet Propulsion Laboratory in Southern California; Liliya Posiolova, MRO, orbital science operations lead at Malin Space Science Systems, San Diego, California; and Ingrid Daubar, InSight impact science lead, Brown University, Providence, Rhode Island.
