The mission intends to employ the robotic arm in burying the tether that conveys data and power between the lander and InSight’s seismometer, which has recorded more than 480 marsquakes. They’ll put their hard-earned wisdom to use in the future. Planning the moves and getting them just right with the commands they were sending up to InSight pushed the team to grow. In fact, they used the arm and scoop in ways they never intended to at the outset of the mission, including pressing against and down on the mole. “Having had the opportunity to take this all the way to the end is the greatest reward.”īesides learning about the soil at this location, engineers have gained invaluable experience operating the robotic arm. What we attempted to do – to dig so deep with a device so small – is unprecedented,” said Troy Hudson, a scientist and engineer at NASA’s Jet Propulsion Laboratory in Southern California who has led efforts to get the mole deeper into the Martian crust. For two years, the team worked to adapt the unique and innovative instrument to these new circumstances. The mole’s design was based on soil seen by previous Mars missions – soil that proved very different from what the mole encountered. The unexpected properties of the soil near the surface next to InSight will be puzzled over by scientists for years to come. In that sense, we’ve been successful: We’ve learned a lot that will benefit future missions to Mars and elsewhere, and we thank our German partners from DLR for providing this instrument and for their collaboration.” “This is why we take risks at NASA – we have to push the limits of technology to learn what works and what doesn’t. It was amazing to see them troubleshoot from millions of miles away,” said Thomas Zurbuchen, associate administrator for science at the agency’s headquarters in Washington. “We are so proud of our team who worked hard to get InSight’s mole deeper into the planet. Doing so is important for a variety of reasons: Future astronauts may need to dig through soil to access water ice, while scientists want to study the subsurface’s potential to support microbial life. While NASA’s Phoenix lander scraped the top layer of the Martian surface, no mission before InSight has tried to burrow into the soil. 28, 2019, to bury the probe, the mission team called an end to their efforts. 9, 2021, the 754th Martian day, or sol, of the mission. InSight’s ‘Mole’ Comes to Rest: The “mole,” a heat probe that traveled to Mars aboard NASA’s InSight lander, as it looked after hammering on Jan. “Fortunately, we’ve learned a lot that will benefit future missions that attempt to dig into the subsurface.” “We’ve given it everything we’ve got, but Mars and our heroic mole remain incompatible,” said HP 3’s principal investigator, Tilman Spohn of DLR.

These sensors are designed to measure heat flowing from the planet once the mole has dug at least 10 feet (3 meters) deep.

Part of an instrument called the Heat Flow and Physical Properties Package (HP 3), the mole is a 16-inch-long (40-centimeter-long) pile driver connected to the lander by a tether with embedded temperature sensors. 9, with no progress, the team called an end to their efforts. After the probe conducted 500 additional hammer strokes on Saturday, Jan. But the soil’s unexpected tendency to clump deprived the spike-like mole of the friction it needs to hammer itself to a sufficient depth.Īfter getting the top of the mole about 2 or 3 centimeters under the surface, the team tried one last time to use a scoop on InSight’s robotic arm to scrape soil onto the probe and tamp it down to provide added friction.

28, 2019, the probe, called the “mole,” has been attempting to burrow into the Martian surface to take the planet’s internal temperature, providing details about the interior heat engine that drives the Mars’ evolution and geology. The heat probe developed and built by the German Aerospace Center (DLR) and deployed on Mars by NASA’s InSight lander has ended its portion of the mission. The heat probe hasn’t been able to gain the friction it needs to dig, but the mission has been granted an extension to carry on with its other science.
