NASA Mars Lander Captures Strikes by 4 Incoming Space Rocks
The InSight team expected to pick up numerous meteoroid strikes, given Mars' proximity to the asteroid belt and the planet's thin atmosphere, which tends to keep entering space rocks from burning up. But the lander's French-built seismometer may have missed impacts because of interfering noise from the Martian wind or seasonal changes in the atmosphere. Now scientists know what to look for, according to NASA, likely resulting in a surge of detections.
“Impacts are the clocks of the solar system,” French lead author Raphael Garcia said in a statement from the Higher Institute of Aeronautics and Space in Toulouse. “We need to know the impact rate today to estimate the age of different surfaces.” Launched in 2018, InSight has already detected more than 1,300 marsquakes. The largest measured a magnitude 5 earlier this year. By comparison, the marsquakes generated by the meteoroid impacts registered no more than a magnitude 2.The Associated Press Health and Science Department receives support from the Howard Hughes Medical Institute’s Department of Science Education.
