Phoenix Mars Lander Working With Sticky Soil University of Arizona

Scientists and engineers on NASA’s Phoenix Mars Mission spent the weekend examining how the icy soil on Mars interacts with the scoop on the lander’s robotic arm, while trying different techniques to deliver a sample to one of the instruments.
“It has really been a science experiment just learning how to interact with the icy soil on Mars – how it reacts with the scoop, its stickiness, whether it’s better to have it in the shade or the sunlight,” said Phoenix Principal Investigator Peter Smith of The University of Arizona.
