Three times smitten by my spear he pressed the dust
The Phoenix lander
has picked up some stuff, and, yup, it is red...,
and we have microscopic images of Martian dust.
30-150 micron dust on the optical microscope - dust kicked up by the lander, probably.
The scoop picked up some white stuff - probably salts they think - hope not all the hard shiny stuff they've seen in the trenches and under the lander is salt deposits.
Getting there.
