Snow spotted in Martian clouds, NASA says

Snow spotted in Martian clouds, NASA says Washington  - The Phoenix Mars lander has found snow falling from clouds above Mars, NASA said Monday.

The snow evaporated before it reached the ground, Phoenix's instruments showed.

"Nothing like this view has ever been seen on Mars," researcher Jim Whiteway of York University in Toronto said. "We'll be looking for signs that the snow may even reach the ground."

Scientists also said they had found calcium carbonate - the main component of chalk - and possibly clay, both of which form only in the presence of liquid water.

Awful mood for NASA jubilee: Is China headed for the moon?Washington  - NASA celebrates its 50th anniversary Wednesday, but the US space agency is hardly in the mood for partying.

Even NASA boss Michael Griffin, who is usually rather a cold technician, recently sounded the alarm. After all, the agency's greatest triumphs, notably the first moon landing, took place almost 40 years ago.

In public, Griffin restrains himself, but in private, he bluntly expresses his concern that US dominance in space could soon give way to China.
