Curiosity's Worst Nightmare: Stuck Rock on the Martian Surface #marsrover #disaster

[00:00:00]on Mars, and a story that is part engineering drama, part slapstick, and entirely endearing. Drilled into a rock, and the rock wouldn't let go. It just grabbed on and refused to release. On April 25th, Curiosity extended its robotic arm and drilled into a rock that the team nicknamed Atacama, after the Chilean desert. When the rover tried to retract the arm, the entire rock lifted off the Martian surface. It had dislodged onto the fixed sleeve surrounding the drill bit and simply came with it. How big was this rock?

[00:00:35]About 45 cm across at its base, around 15 cm thick, and roughly 13 kg, or about 4 and 1/2 kg on Mars due to the lower gravity.

[00:00:48]A substantial chunky rock dangling off the end of a rover arm, 140 million kilometers from the nearest mechanic.

[00:00:56]And the solution isn't as simple as just shaking it off.

[00:01:00]Every command you send to Curiosity takes up to 30 minutes to arrive. Which is what made the next week so dramatic.

[00:01:08]The engineering team spent several days trying different approaches, repositioning the arm, vibrating the drill, trying different angles. For days, Atacama refused to budge. They even watched the rock slowly shed sand as the arm moved, but it stayed put.

[00:01:26]Finally, on May the 1st, the team went all in, tilting the drill, rotating it, vibrating it, and spinning the drill bit simultaneously.

[00:01:35]They were prepared to try a multiple rounds. The rock came off on the first attempt. And promptly shattered when it hit the Martian ground. Atacama's last stand.

[00:01:46]>> And Curiosity, for its part, is now happily back to its regular science operations.
