"The InSight team can rest a little easier tonight now that we know the spacecraft solar arrays are deployed and recharging the batteries", Tom Hoffman, a project manager at NASA's Jet Propulsion Laboratory, which leads the mission, said in a statement.
InSight will operate on the surface for one Martian year, plus 40 Martian days, or sols, until November 24, 2020.
The National Aeronautics and Space Administration (NASA)'s InSight spacecraft on Monday touched down safely on Mars, kicking off its two-year mission as the first spacecraft created to explore the deep interior of another world.
If all continues to go to plan, the $1-billion worldwide mission will see the InSight spend the next two years exploring Mars' interior.
NASA TV featured live-streaming coverage of the landing.
InSight's 1.8m robotic arm will be used to place the instruments on the Martian surface, where they will be calibrated.
The spacecraft took the image of itself from the red dusty planet, arguably making it the first selfie on Mars. It will now operate from there for the next two years, trying to study the red planet. InSight will also emit radio waves that will let scientists on Earth determine how much Mars moves when it rotates, giving them a sense for the makeup of the core of the planet.

The US space agency tweeted one photograph, showing part of the InSight spacecraft and the Martian surface in the distance.
InSight, part of a $1 billion worldwide mission, features a German-led mechanical mole that will burrow down 16 feet to measure the planet's internal heat.
"[The mission] will tell us the difference between Mars and the Earth, and that's fundamental in terms of understanding what has made the Earth's evolution so specific that it harboured life".
It will take weeks for InSight to get started on its primary work, and months to years for the mission to get solid science results about the interior of Mars, but that is the kind of mission that we've signed on to with this lander.
The CNES provided the Seismic Experiment for Interior Structure (SEIS) instrument, and the DLR provided the Heat Flow and Physical Properties Package (HP3) instrument, Bridenstine said.
Shortly after touchdown, the lander relayed an image of the Martian surface.
On Monday, NASA celebrated the successful journey of a lander on Mars.
In 2020, it will land another rover in an ancient lake bed to directly look for evidence of microbes, dead or alive.
