NASA's Phoenix Mars lander was not the only one doing the shaking.
An image from the Phoenix lander shows two trenches it has dug in the Martian soil.
Scientists operating the spacecraft broke into song and dance Wednesday after learning that their latest effort to shake lumps of Martian soil into a tiny testing oven worked.
Mission scientist William Boynton, who leads the oven experiment, recalled how he danced to the disco tune "(Shake, Shake, Shake) Shake Your Booty" after announcing the good news to his team.
"The dirt finally did start to flow, and we actually got a full oven," said Boynton, of the University of Arizona in Tucson. "So that problem is now behind us."
