Is the ground around Phoenix darker due to the landing thrusters do you reckon?

I like what Bad Astronomy had to say about the parachute picture:

That is exactly what you think it is: Phoenix descending to the Martian surface underneath its parachute. This incredible shot was taken by the HiRISE camera on board the Mars Reconnaissance Orbiter. You can easily see the ‘chute, the lander (still in its shell) and even the tether lines!

Think on this, and think on it carefully: you are seeing a manmade object falling gracefully and with intent to the surface of an alien world, as seen by another manmade object already circling that world, both of them acting robotically, and both of them hundreds of million of kilometers away.

Never, ever forget: we did this. This is what we can do.

Yeah, what he said^.
This is what the word "awesome" was invented for.

Sublime, in the truest sense of the word.

ICE IS NICE

A view of the ground underneath NASA's Phoenix Mars Lander adds to evidence that descent thrusters dispersed overlying soil and exposed a harder substrate that may be ice.

The image received Friday night from the spacecraft's Robotic Arm Camera shows patches of smooth and level surfaces beneath the thrusters.

"This suggests we have an ice table under a thin layer of loose soil," said the lead scientist for the Robotic Arm Camera, Horst Uwe Keller of Max Planck Institute for Solar System Research, Katlenburg- Lindau, Germany.

"We were expecting to find ice within two to six inches of the surface," said Peter Smith of the University of Arizona, Tucson, principal investigator for Phoenix. "The thrusters have excavated two to six inches and, sure enough, we see something that looks like ice. It's not impossible that it's something else, but our leading interpretation is ice."

I also want to add that "lead scientist for the Robotic Arm Camera, Horst Uwe Keller of Max Planck Institute for Solar System Research," is the greatest name/title/affiliation combination ever.

is the DVD copy protected?

This isn't really coming from Mars though, is it?

Well the data is coming from Mars, scientists are interpreting it and an intern is anthropomorphising it and posting it to twitter.

what a job!

OK, this is from Spirit not Phoenix, but whatevs. Holy shit.

alien!

In phoenix news I hear they are having problems getting the dirt in the oven for mass spec.

xpost -- Well it's nice to know what the new Jesu album cover will be.

That Spirit shot is gorgeous.

Snowfall!

Remember the movies of clouds floating above the Phoenix Lander? Further study with the lander's Lidar instrument has detected snow falling from Martian clouds. "The clouds are composed of ice crystals, and some of the crystals are large enough to fall through the atmosphere," said Jim Whiteway, lead scientist for the Meteorological Station on Phoenix. Whiteway and several researchers shared recent findings from Phoenix at a press briefing today. "So snow is falling from the clouds and we are going to be watching very closely over the next month for evidence that the snow is actually landing on the surface. This is a very important factor in the hydrological cycle on Mars, with the exchange of water between the surface and the atmosphere."

"Nothing like this view has ever been seen on Mars," Whiteway added.

From Phoenix images and data, scientists have observed water condensing in the atmosphere. In recent weeks, as the temperatures fall in onset of winter on Mars' northern plains, frost, ground fog and clouds are prevalent. "This is now occurring every night," said Whiteway. "The Lidar is able to probe the inner structure of the clouds. It emits pulses of light upward into the atmosphere and detects what is scattered back. The laser emits pulses of light 100 times per second, so if you were standing beside the lander looking upward, you'd see a continuous green beam." Data and images of the beam show bright spots in beam is where it is reflecting off ice crystals, and also where it reflects off clouds, a few miles above the surface.

The snow starts falling from a height of 4 km and fall down to 2 km. At that point the observations stopped, as they were initially set up for a limited amount of time. Further observations will be done to see if the snow is actually falling down to the surface of the planet.

:-D I love stuff like this.

Snow on Mars! Such a beautiful image, would love to see it.

More on the snowfall at night

By the way, there's carbon-dioxide snow on Mars too

In 2008, we learned from the Phoenix Mars lander that it snows in Mars northern hemisphere — perhaps quite regularly – from clouds made of water vapor. But now, Mars Reconnaissance Orbiter data has revealed the clearest evidence yet of carbon-dioxide snowfalls on Mars. Scientists say this is the only known example of carbon-dioxide snow falling anywhere in our solar system.

“These are the first definitive detections of carbon-dioxide snow clouds,” said Paul Hayne from the Jet Propulsion Laboratory, lead author of a new study published in the Journal of Geophysical Research. “We firmly establish the clouds are composed of carbon dioxide — flakes of Martian air — and they are thick enough to result in snowfall accumulation at the surface.”

Scientists have known for decades that carbon-dioxide exists in ice in Mars’ seasonal and permanent southern polar caps. Frozen carbon dioxide, sometimes called “dry ice” here on Earth, requires temperatures of about -125 Celsius (- 193 degrees Fahrenheit), which is much colder than needed for freezing water.

Even though we like to think Mars is a lot like Earth, findings like this remind us that Mars is indeed quite different. But just as the water-based snow falls during the winter in Mars’ northern hemisphere, the CO2 snowfalls occurred from clouds around the Red Planet’s south pole during winter in the southern hemisphere.
