The dramatic arrival of the $993 million spacecraft - created to listen for quakes and tremors as a way to unveil the Red Planet's inner mysteries, how it formed billions of years ago and, by extension, how other rocky planets like Earth took shape - marked the eighth successful landing on Mars in Nasa's history.
On clear days, the panels will provide InSight with between 600 and 700 watts, which is roughly enough to power a standard kitchen blender.
The suite of geophysical instruments will take measurements of Mars' internal activity like seismology and the wobble as the sun and its moons tug on the planet.
But as expected, the dust kicked up during the landing obscured the first picture InSight sent back, which was heavily flecked. The photo was captured after solar panels fruitfully convoluted from its sides so that its batteries can be charged and was transmitted through the Mars Odyssey orbiter that hovers around the planet and transmits the messages back to the Earth.
Once the dust settles this is what In Sight will look like when it starts performing science experiments
NASA has successfully landed a probe on the surface of Mars. Because the satellites are at Mars, they can communicate much faster with vehicles like InSight on the planet's surface. MarCO shared data about InSight when it entered the Martian atmosphere for the landing.
The German Aerospace Center (DLR) provided a self-hammering mole that can burrow 16 feet (five meters) into the surface - further than any instrument before - to measure heat flow.
The area where InSight is landing is called Elysium Planitia, a particularly flat area of Mars where hazardous loose rocks are absent. NASA's next mission, the Mars 2020 rover, will prowl for rocks that might contain evidence of ancient life.
"I'm embedded in meetings pretty much all day, as we go over the technical details", said Banfield. "It's been exciting to see the view from nearly 1,000 miles (1,600 kilometers) above the surface".
"CubeSats have incredible potential to carry cameras and science instruments out to deep space", said John Baker, JPL's program manager for small spacecraft. "The best of NASA is yet to come, and it is coming soon". Dozens of operations and thousands of lines of code were pre-programmed into the machinery and memory of the spacecraft and by all accounts they executed perfectly.
The MarCO and InSight projects are managed for NASA's Science Mission Directorate, Washington, by JPL, a division of the California Institute of Technology, Pasadena.
