The Phoenix spacecraft on Mars is finally getting to grips with the clumpy soil at its landing location.Early efforts to grab samples for study in the onboard lab had been frustrated by the cloddy nature of the ground.
But by shaking the scoop bucket on the end of its robotic arm, Phoenix now has a very effective technique to deliver fine samples to test instruments.
Mission scientists report that Phoenix has made a very delicate dusting of material across a microscope.
This Microscopy, Electrochemistry and Conductivity Analyzer (MECA) unit can view the structure of grains at scales never before seen on Mars - down to as small as about 100 nanometres, one one-hundredth the width of a human hair.
The success in getting a good sample onto MECA comes off the back of news that a usable sample has also now finally made its way into the first of eight ovens on Phoenix.
