Nasa’s InSight lands in good Martian area, only at slight angle

LOS ANGELES: NASA’s unmanned Martian quake sensor, InSight, has landed at a slight angle on the Red Planet, and experts are hopeful the spacecraft will work as planned, the US space agency said Friday.

The US$993mil ( RM4.15bil) 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 neighbour formed.

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

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

Therefore, experts are hopeful that its two main instruments – a quake sensor and a self-hammering mole to measure heat below the surface – will work as planned.

“We couldn’t be happier,” said InSight project manager Tom Hoffman of NASA’s Jet Propulsion Laboratory.

“Coming down in an area that is basically a large sandbox without 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 near a rocky area would have made deployment of the solar arrays and instruments tricky.

Better images are expected in the coming days 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 are accurate, it bodes well for both instrument deployment and the mole penetration of our subsurface heat-flow experiment.”
