NASA Mars Insight Mars has been prepared with a number of instruments to explore the interior of the red planet.
One of them is a heat flow probe built by the German Aerospace Center (DLR) to bury itself in the surface of Mars in the manner of a mole in order to take the temperature of Mars. The data collected could give us new clues about the formation of the neighbor of the Earth.
But InSight had a setback: orders from Earth did not reach Mars in time for the planned deployment for "unknown technical reasons," according to a statement released yesterday. InSight will therefore have to delay the deployment of the two-day thermal probe from Earth as a result.
Bad news for our mole #March: Unfortunately, scheduled orders could not be linked yesterday, resulting in a 2 day delay for the start of pounding. Find more details in Tilman Spohns #DLRblog-register. #MarsMaulwurf https://t.co/r3iJMbEQ8o

The thermal probe, called the heat flux and physical properties probe (HP3), is intended to sink into the first five meters (5 meters) of the Martian surface – if all goes as expected – to measure the heat coming out of the planet. According to NASA, this is deeper than any other scientific instrument made by humans on Mars.
Other instruments on board are built to measure gravitational movement, seismic activity and the magnitude of Mars movement when it revolves around the Sun.
But nothing guarantees that the mission of the thermal probe will proceed without additional complications. There is always the major risk of hitting an impenetrable rock – which would end the thermal probe until it installs a new dig site.
"Although we have tested the mole thoroughly and diligently, there is uncertainty," said Tilman Spohn, chief engineer of the mission, in an article in the DLR blog. "This has never been done before on Mars or on another terrestrial planet."
