With Mars InSight Lander Stuck, NASA is trying to penetrate the Earth Branches



  Nassa Penetration Devices

Engineers prepare NASA's Mars InSight NAVAR NAVIGATOR for launch on the Red Planet. Last month, NASA's Mars InSight navigation system began digging into the Red Planet. The HP Tool 3 is designed to excavate and measure Mars from the underground, revealing new geological evidence of how heat passes through the Martian soil. The part of this instrument that actually rises in the ground is known as the mole. It had to penetrate deep up to 16 feet. But he stopped only a few hours after he started digging. The mall made it only one foot deep.

Since then, mission scientists have worked hard, trying to figure out how to get it back. Their best presumption, according to Tilman Sponn's principal investigator, is that the moth hit rock or gravel. But he admits that this is partly speculation. It is also possible that the training will somehow be pressed against its own supporting structure. The team should explore all the options before acting.

To understand, NASA's team turned to a set of diagnostic tools, such as the InSight camera and other sensors. But they also try to recreate the problem of engineering models here on Earth. InSight has a twin, currently in Berlin, and many more copies of his various tools, including the mole. Engineers have been practicing these cloning cassettes since they failed, trying to recreate the problem they see on Mars, and then figure out a way to get earth mills to dig up again. Only then will they try them in the real InSight.

Spohn points out that the whole process is slow and may be another month before the team is ready to try Mars repair attempts. Even after they make a decision, they may have to write new software, test it on Earth's models, and then send it to the real InSight before any action happens. The aerospace center that provided the HP tool 3 and NASA's Jet Propulsion Laboratory, which runs the larger InSight mission, are working together to find the cause and possible solutions to the InSight digging problem.

Conclusions

There are scenarios that could stop the mission where it stands. "If there's a 1-meter block of stone, Sponn says, there's no way we can handle that." The hope is that what we are fighting for is a small rock, say half the length of a mall. We can repel it by continuing to get stuck. "Span called this" brute force "approach. In the hand of White to give him more strength and limit the withdrawal. At the moment, the problem may be that the moon bounces off the rock instead of moving through it, so adding more pressure can help it dig it. But pressure is not what the hand is intended for, so testing with Earth's models would be so important before testing them on the 800 million dollar vessel on Mars. the cabin, no repairs to the Red Planet. "If you make a mistake, it's gone," says Span. But he also points out that if the moon starts digging again freely, it can reach its target depth within about four hours and there is still much energy to do. InSight itself is solar powered and designed for two Earth years. InSight arrived on Mars only in November, so he has a long time left.

If the worst case occurs and the mole is unable to continue, Spohn admits: "We will lose a significant part of science." go down at least 10 feet to reach your goal of measuring the heat flow from the inside of Mars. "But there are still things to be done," he says. Other InSight tools work as planned and will still receive information from the bottom of the dirt on Mars, which InSight has digested. "This will still be something that has not been done before," Span says. "Not as brave as we originally planned, but it is still a good science."
