Mars spacecraft record meteor strikes that made craters hundreds of feet wide

Nasa's InSight lander measured the seismic waves as the Reconnaissance Orbiter sent images of the impact

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 500ft (150 metres) across, scientists reported on Thursday in the journal Science.
