Mars Soil Clumpier Than Expected

Mars Soil is Clumpy

“We’re a little surprised at how much this material is clumping together when we dig into it,” said Doug Ming a Phoenix science team member from NASA’s Johnson Space Center, Houston.

The soil’s physical properties are proving to be a challenge for getting a sample intended for one instrument to pass through a screen over a delivery opening. The instrument is the Thermal and Evolved-Gas Anaylzer, or TEGA, designed to bake and sniff samples to identify some key ingredients. The analyzer vibrated the screen for 20 minutes on Sunday but detected only a few particles getting through the screen, not enough to fill the tiny oven below.

“We are going to try vibrating it one more time, and if that doesn’t work, it is likely we will use our new, revised delivery method on another thermal analyzer cell,” said William Boynton of the University of Arizona, lead scientist for the instrument.
