First Marsquakes Ever Seen Shake up Science of the Red Planet

For the first time ever, a tremor, similar to a small earthquake, has been recorded on Mars. This marsquake was detected by the Seismic Experiment for Interior Structure (SEIS) probe, carried to Mars with the InSight spacecraft. Researchers believe the event was caused by heating and cooling of the Martian surface, resulting in cracking of the crust on the Red Planet. This is the first discovery in the brand new science of Martian seismology.

Earth’s Oldest Rock Found – It was Hiding on the Moon!

The oldest rock from Earth ever found was recently discovered hiding on the Moon. The four-billion-year-old rock was found among the samples returned from the Moon by the astronauts of Apollo 14.

Once there, the area was hit by an asteroid, burying big Bertha, before another impact raised it, once again, to the surface. It was returned to Earth in 1971 by astronauts Alan Shepard and Edgar Mitchell.
