Two NASA spacecraft have recorded the biggest meteor strikes and impact craters on Mars than ever before. One of the spacecraft is on Mars’ surface. The other is orbiting the planet. The impacts last year produced seismic waves that travelled thousands of kilometers across Mars. These are the first seismic waves scientists have ever found near the surface of another planet. The hits produced craters nearly 150 meters wide, scientists reported Thursday in the journal Science. The larger of the two strikes threw out large pieces of ice. That information may help researchers find ways future astronauts can use Mars’ natural resources. The Insight lander measured the seismic waves, while the Mars Reconnaissance Orbiter provided pictures of the craters.
