Mars Lander Sees Falling Snow

Tuesday, September 30th, 2008

According to an article on NASA’s website the Mars Lander has detecting falling snow that is vaporizing before hitting the ground. Canadian researchers are behind the experiment and equipment used to determine this.

From the article:

PASADENA, Calif. — NASA’s Phoenix Mars Lander has detected snow falling from Martian clouds. Spacecraft soil experiments also have provided evidence of past interaction between minerals and liquid water, processes that occur on Earth.

A laser instrument designed to gather knowledge of how the atmosphere and surface interact on Mars has detected snow from clouds about 4 kilometers (2.5 miles) above the spacecraft’s landing site. Data show the snow vaporizing before reaching the ground.

“Nothing like this view has ever been seen on Mars,” said Jim Whiteway, of York University, Toronto, lead scientist for the Canadian-supplied Meteorological Station on Phoenix. “We’ll be looking for signs that the snow may even reach the ground.”

It has finally happened, the Mars Phoenix rover has confirmed the existence of water on Mars.

“We have water,” said William Boynton of the University of Arizona, lead scientist for the Thermal and Evolved-Gas Analyzer, or TEGA. “We’ve seen evidence for this water ice before in observations by the Mars Odyssey orbiter and in disappearing chunks observed by Phoenix last month, but this is the first time Martian water has been touched and tasted.”
