Phoenix Lander’s Arrival on Mars & Anniversary of JFK’s Moon Challenge

Forty-seven years ago, today, President John F. Kennedy stood before a Joint Session of Congress and announced the United States’ ambitious goal of sending an American to the Moon before the end of that decade. While he did not live to see that goal achieved, millions of others did, on July 20, 1969, when Neil Armstrong stepped down onto the lunar surface and uttered those famous words, “That’s one small step for man, one giant leap for mankind.”

It is fitting that tonight, some four decades later, humans will once again turn their attention to space as NASA strives for another first, this time on a world much more distant than the moon. At 7:46 PM EDT, the Mars Phoenix Lander will enter the Martian atmosphere to attempt a touch-down landing that hinges on the success of a complex seven-minute series of events. The unmanned craft will set down in a region further north than any previous Mars’ missions, and it will sample a distant world like has never before been done – all in a quest that seeks an answer to the question, “Can Mars, or could it ever, support life?”

NASA expects that more than half-a-million viewers will tune into the live broadcast of this next major step in Mars exploration on NASA TV, not only as many people watch from their own home computers, but as dozens of museums host large-scale viewing events and Discovery Communications airs live coverage on their Science Channel, as well.

SLOOH, too, intends to tune into this momentous event. If missions are running, we’ll stream NASA’s live broadcast through SLOOHRadio, and we’ll even play that dramatic Kennedy speech, during the Phoenix broadcast’s quieter moments, or immediately following.

Mars Orbiter Captures First Extra-Terrestrial Avalanche In Progress

mars avalanche

Fate truly smiled on NASA’s MRO mission last month, and the team scientists are sharing their good fortune with the world this week. Newly released images show billowing clouds of Martian dust during an avalanche as it happened – an extra-terrestrial event that has never been seen before in progress.

The images, obtained with the Mars Reconnaissance Orbiter’s HI-RISE camera on February 19, were a complete surprise for the team. They are not yet sure what triggered the event, but it was located at the Martian north pole region during the spring - with warmer weather likely affecting the ice to trigger the massive fall. The avalanche occurred along a 2300 ft. tall cliff inclined by more than 60 degrees in some places. Other possible mechanisms include a nearby meteorite impact or a Marsquake.

The false-color image below reveals at least four individual landslides. The white region at image left illustrates a thick layer of carbon dioxide frost along the top of the cliff, while the reddish fractured area at center is the highly-inclined slope. The dusty debris clouds on the right measure about 600 feet across and are also 600 feet above the cliff base.

The MRO launched in August 2005, arrived to Mars seven months later, and began working full-time November 2006. In addition to collecting data about the red planet, MRO will also serve as a communication satellite for future surface missions, including NASA’s Phoenix Lander. While the current mission timeline ends December 2010, the craft is equipped to continue through 2015 if needed.
