Nasa’s Martian quake sensor, InSight, has landed at a slight angle on the Red Planet, but experts hope the spacecraft will still work as planned, the US space agency said on Friday.

The nearly billion-dollar lander arrived on Monday at its target, a lava plain named Elysium Planitia, for a two-year mission aimed at better understanding how Earth’s neighbouring planet formed.

“The vehicle sits slightly tilted (about 4 degrees) in a shallow dust- and sand-filled impact crater known as a ‘hollow’,” Nasa said in a statement.

InSight was designed to operate on a surface with an inclination up to 15 degrees.

So experts are hopeful its two main instruments – a quake sensor and self-hammering mole to measure heat below the surface – will still work properly.

“We couldn’t be happier,” said InSight project manager Tom Hoffman of Nasa’s Jet Propulsion Laboratory. “There are no landing pads or runways on Mars, so coming down in an area that is basically a large sandbox without any large rocks should make instrument deployment easier and provide a great place for our mole to start burrowing.”

The first pictures from the lander show just a few rocks in the vicinity, more good news since touching down right near a rocky area would have made deployment of the solar arrays and instruments tricky.

Better images are expected once InSight sheds the dust covers on its two cameras.

“We are looking forward to higher-definition pictures to confirm this preliminary assessment,” said Bruce Banerdt, principal investigator of InSight at Nasa. “If these few images – with resolution-reducing dust covers on – are accurate, it bodes well for both instrument deployment and the mole penetration of our subsurface heat-flow experiment.”
