The Robot Mole, designed to measure heat below the surface of Mars, has been in the ground for MONTHS and now needs to be rescued by NASA's InSight Lander.
- The InSight Lander Mole has been trapped underground since March.  According to NASA, the problem is the lack of friction when the ground moves away from the pier.
- A new plan proposes to raise the support structure so that the problem can be investigated.
- From there, the lander's robotic arm moves the ground back to the probe] NASA will launch its first movement tomorrow, taking care not to push the probe
NASA is preparing for a rescue operation and hopes to rescue a critical instrument on its Mars Lander that remains trapped just inches below the surface.
In March, after less than a year on Mars, InSight Lander of NASA reported that a critical instrument – a & # 39; mol & # 39; probe, was designed to bury itself in the planet and assess its heat output – hit a hook.
For several months, the probe, which was supposed to drill 16 feet down, has been trapped just 30 centimeters below the surface of the planet in less than a month.
A newly developed plan could, however, pull out the probe once and for all.

NASA's InSight probe will attempt to rescue a critical instrument trapped beneath the Martian surface.
According to NASA, the team this month will try to use the lander's robotic arm to get the probe with the Heat Flow and Physics Property Pack (HP3) back on track.
First, scientists found that the probe, which consists of a thorn and a rope, could have been stuck on a particularly strong but new rock. The slander shows that the chances for it are only a few percent.
NASA says instead that the device has encountered a problem with the ground itself.
Scientists believed that as soon as the mole began to hammer on the surface, it would break off the rock and form sediments around the probe, creating friction.
Instead, the floor appears to have caked and to move away from the instrument, creating an empty space between the spine and the surface.
"Hooking requires some specific movements of the mole that it may have done, but probably not. The distribution of the stones on the surface shows that the probability of encountering a stone of the correct depth is only a few percent, "said Tilman Spohn, head of the HP3 instrument at the German Space Agency DLR , in a blog post.
"The friction hypothesis is the most likely hypothesis and, importantly, the hypothesis we can do something about to help the mole."
To better understand the problem, NASA has proposed slightly raising the support structure and moving the housing so that a clear image is created.
This solution could, however, tear the mole out of the ground without getting it back, so NASA manages the maneuver in three phases.
The first will take place tomorrow.
From there, NASA will develop a bailout that could use the robotic arm of the lander to bring dirt near the probe.
NASA is no stranger to problems with their Mars missions. In 2009, the Rover Spirit was in a sand pit and could not reach a vantage point high enough to recharge its systems with solar panels.
Similarly, the Mars Rover Opportunity was trapped in a huge sandstorm last year, blocking sunlight long enough to lose communication with the device.
WHAT ARE THE THREE KEY INSTRUMENTS OF INSIGHT?
Seismometer : The InSight lander is equipped with a seismometer equipped] SEIS, listening to the pulse of Mars.
The seismometer detects the waves that travel through the inner structure of a planet.
The study of seismic waves tells us what the waves could produce.
On Mars, scientists suspect that the perpetrators may be Marsquakes or meteorites beating the surface.
Heat Probe: InSight's HP3 heat flow sensor digs deeper than any other blades, drills or probes on Mars.
It is investigated how much heat still flows from Mars.
Radio Antennas: Like Earth, Mars wobbles slightly as it turns around its axis.
To investigate, two radio antennas that are part of the RISE instrument closely track the lander's position.
This helps scientists to test the planet's reflections and explains how the deep internal structure affects the planet's motion around the sun.
