Here in Minnesota, we've turned the corner and we're now heading toward winter. Snow can't be that far behind. This week on Mars, NASA's Phoenix explorer has dectected snow falling on the Red Planet. Here's a complete video report. Unfortunately for Martian school children, the snow was so light that it melted before touching down on land, removing the possiblity of having a snow day off from school.

Rumors are circulating that NASA's Phoenix Lander team has held briefings with the White House regarding some sort of forthcoming big announcement. It's unclear whether any briefings actually took place, but some folks wonder if NASA is hiding something. It could be the space agency is just doing their usual pre-hype of an upcoming announcement. Whatever the case, you can join in the speculation by going here and here or even here. Or you can listen to today's Phoenix Media Telecon and see if you can get some clues of what's happening.

We've had a number of post about private space travel recently. Here's the story of a private rocket shot off over the weekend that's disappeared just a couple minutes after launch. Where did it go? If it was one of those model rockets I shot off when I was a kid, it would be wedged between some tree branches.

NASA scientists have confirmed that on-board analysis of ice samples scooped up by the Phoenix Mars Lander earlier this summer prove water exists on the planet.

"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."

-- William Boynton, lead scientist for the Thermal and Evolved-Gas Analyzer.

The mission has been extended through September 30.

Man on the Moon

On this day in 1969, less than nine years after President John F. Kennedy set the seemingly impossible goal of sending a man to the Moon and back, Apollo 11 astronaut Neil Armstrong became the first human to walk on the Moon. He was joined a short time later by astronaut Edwin Aldrin. The two explorers spent two-and-a-half hours gathering moon rocks, setting up experiments, and planting the American flag, while astronaut Mike Collins orbited the Moon waiting to rendezvouz with the Lunar Module for the return trip to Earth. Here are lots of links about the Apollo lunar program

Two NASA scientists propose building giant telescopes on the Moon, using Moon dust as raw material. If successful, the telescopes would be larger than anything on Earth. And with no atmosphere to distort images, the pictures would be sharper, too.

Ice on Mars

A few days ago on Mars, the robotic scoop on NASA’s Phoenix Lander uncovered some white, dice-sized chunks of material in a trench it was digging. Today, some of those same bright chunks are nowhere to be seen leading NASA scientists to think they were ice that has since evaporated.

"These little clumps completely disappearing over the course of a few days, that is perfect evidence that it's ice,” said Principal Investigator Peter Smith of the University of Arizona, Tucson. There had been some question whether the bright material was salt. Salt can't do that."

Junk food or junk science?: Six hours worth of advertising for Doritos chips have been beamed out in to space as a signal to other life forms that there's crispy, tasty, good times available on Earth.

We can’t escape advertising, can we? It’s there along the roadside, imbedded on the results of our web search and even on the bathroom stall wall. And now it’s off into space.

Six-straight hours of Doritos advertising have been beamed out into space from a European space station located on a Norwegian island in the Arctic Circle. The message is directed at the Ursa Major constellation, which is just 42 light years from Earth. That location was targeted as astronomers figure it has the best chances of hosting a planet that can support life forms, and potential Doritos eaters.

And while the effects of advertising are always hard to measure, these space scientists aren’t expecting the message to have a huge impact on Doritos sales. The actual advertisement has been broken down into a MPEG file that is just a series of “0s” and “1s”. The hope is that any one receiving the message will understand it as a message coming across with some intelligence and to perk the receiver’s curiosity in wanting to see where it came from.

But I ask you, is it really intelligent to try to entice an alien to come 42 light years to Earth in the hope of getting some Doritos? After all, the package expiration date doesn’t come close to lasting that long.

Actually, Doritos made a donation to the space station in exchange for having its advertisement sent into space. But I ask you, what kind of message would you send out into space to encourage intelligent life to come investigate Earth?

When this image first appeared on computers at the Jet Propulsion Laboratory in California, scientists there were head-over-heels about the possibility that the Phoenix lander that settled on Mars last week had finally discovered tangible evidence of the Abominable Snowman. They even named it Yeti after the legendary Himalayan creature.

But their excitement soon turned to disappointment when they realized the marking was just a test scraping made by the Mars lander's robotic arm. All was not lost however. Their emotional rollercoaster was soon headed upward again as they discovered that the lander's descent engines had blown away the topsoil and uncovered a large patch of ice right beneath the spacecraft. Exactly what it was sent there to find!

Scientist are hopeful the ice extends into the region the lander will be sampling in the coming days. They may even hope to find evidence of Elvis, but personally I think they should lower their expectations and stick to searching for other, less iconic, signs of life on the planet.
