Mars lander starts digging on red planet
NASA’s newest Mars lander has started digging into the red planet, but hit a few snags, scientists said. The German drilling instrument on the InSight lander struck what appeared to be a couple of stones.
It only managed to burrow between half a foot (18cm) and about 1.5ft (50cm), far short of the first dig’s goal, said the German Aerospace Centre.
The hammering device in the “mole” was developed by the Astronika engineering company in Poland.
“This is not very good news for me because although the hammer is proving itself… the Mars environment is not very favourable to us,” said the company’s chief engineer, Jerzy Grygorczuk.
Over time, the team is shooting for a depth of up to 16ft (five metres), which would set an otherworldly record.
The lander is digging deep to measure the planet’s internal temperature.
InSight landed on Mars last November.
Flight controllers at Nasa’s Jet Propulsion Laboratory in California sent commands to the lander on Thursday to begin digging.
It will rest for a bit before burrowing again.
The spacecraft already has a seismometer on the surface, listening for potential quakes.
The lander is stationary, but has a robot arm to manoeuvre these two main experiments.
