In March this year, a portion of the drill, known as the mole, was rammed into the gritty soil, which made movement impossible. To release it, the drill pack was moved as far away from the belt as possible and, with the help of the machine's robotic arm, pressed the drill against the ground in a move known as "nailing."
This seems to be working, and training starts moving again earlier this month. However, Mars is not yet ready to give up its secrets and NASA has announced that the mole has been thrown out of the ground.
Mars continues to surprise us. While digging this weekend, the mole retreated to about half the earth. The ex ante evaluation indicates the unexpected soil properties as the main cause. A team that looks at the next steps. #SaveTheMole #Tamamwork pic.twitter.com/UURvU8VTwZ

In a blog post, NASA mo has pulled away halfway from its hole over the weekend, probably because of soil conditions. This means that the team now has to calculate whether they can move the robotic arm from the mole to be able to see in more detail what is happening with the soil.
Not all is bad news for InSight, however. The Landscape Seismic Experiment (SEIS) tool on the Lander collects data on sailors who shake the planet's interior, which can help scientists learn about the internal structure of Mars, and there are even audio recordings of planet sounds that you can to listen.
The InSight team will continue to test ways to save a stuck workout. "One possibility observed when testing the Earth is that the soil can fall at the top of the bank as it bounces, gradually filling the hole in front of it, as the mole pulls back," they say in Twitter . They will announce their new workout plan in the next few days.
