NASA picks up 'Marsquake' for the first time

The space agency's InSight lander has successfully picked up a seismic event on the Red Planet.
The quake, which is the first ever to be detected on a planetary body beyond the Earth and the Moon, was picked up on April 6th using a seismometer placed on the surface by the probe's robotic arm.

Scientists believe that the seismic event was caused by either a meteor impact or movement within a crack deep beneath the surface.

"It's probably only a Magnitude 1 to 2 event, perhaps within 100km or so," said Professor Tom Pike. "There are a lot of uncertainties on that, but that's what it's looking like."

It is hoped that seismic readings from Mars will help to build up a picture of its interior.

"This particular Marsquake - the first one we've seen - is a very, very small one," said InSight mission chief scientist Dr Bruce Banerdt. "In fact, if you live in Southern California like I do, you wouldn't even notice this one in your day-to-life."

"But since Mars is so quiet, this is something that we're able to pick up with our instrument."

You can listen to what the seismometer picked up for yourself in the video below.

The heat probe is apparently still stuck. They've been trying to work out the problem at JPL, using an Earth-bound duplicate of the InSight Lander. The three likeliest answers are: The mechanism that reels out the cable attached to the heat probe is jammed. The probe created a hollow in the soil, or encountered a natural one, so that the hammer-drill has nothing to brace itself against, as it bores. The drill merely rebounds after each hammer blow. A rock too large for the hammer drill to either break through or dislodge has been encountered.  They have apparently used the camera to check the ... [More]

The Russians were probably digging a trench by dropping a series of nukes on the far side, nothing to worry about.
