Mars Lander Sees Falling Snow

Riding with Robots writes "NASA reports that the Phoenix Mars Lander has detected snow falling from Martian clouds. According to the Canadian team running a weather experiment, a laser instrument designed to study how the atmosphere and surface interact on Mars has detected snow from clouds about 4 kilometers above the landing site. Data shows the snow vaporizing before reaching the surface, but one of the mission scientists said, 'We'll be looking for signs that the snow may even reach the ground.' Spacecraft soil experiments have also provided evidence of past interaction between minerals and liquid water."

NASA Mars Lander Sees Falling Snow, Soil Data Suggests Liquid Past

WASHINGTON, Sept. 29 /PRNewswire-USNewswire/ -- NASA's Phoenix Mars Lander has detected snow falling from Martian clouds. Spacecraft soil tests 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, detected snow from clouds about 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

Rover Sand Traps Provide Clues on Mars Climate

If you watched the "Five Years on Mars" documentary on the National Geographic channel about the Mars Exploration Rovers, you probably saw how both rovers have gotten stuck in some of the small sand dunes on Mars surface. These dune fields on Mars are a bit of a mystery to planetary geologists, and in fact, there is nothing like them on Earth. The fields of rippled sand on Mars, called Transverse Aeolian Ridges (TARs), are found over large areas across Mars. The dunes themselves are smaller than the gigantic dunes also found on Mars, but the fields are bigger than any sand ripple fields found on Earth. TARs hold clues to past and present climate processes, and since they can be death traps for rovers, scientists want to know more about these unusual features.

5 Years At Mars: The Best of Mars Express

In December, the Mars Express spacecraft will celebrate the fifth anniversary of its arrival at Mars. In observation of this milestone the German Aerospace Center DLR has put together a collection of some of the best images from the High-Resolution Stereo Camera (HRSC), the main camera on board the spacecraft. The stunning, high resolution images this instrument has produced of Mars' surface are nothing short of jaw dropping, and they have provided new perspectives and new discoveries about our neighboring planet. One of the iconic images from Mars Express is the image above of water ice inside a crater near Mars North Pole.

Mars Satellite's First Weather Report

The Mars Reconnaissance Orbiter has been circling Mars for over two years now, and has provided unprecedented views of the Red Planet with its HiRISE Camera. But did you also know that MRO is a weather-monitoring satellite, too? The Mars Climate Sounder instrument is examining the Martian atmosphere and has issued its first Mars weather report. "It has taken 20 years and three missions but we finally have an instrument in orbit that gives us a detailed view of the entire atmosphere of Mars and it is already giving us fresh insights into the Martian climate," said Professor Fred Taylor of Oxford University. Within a paper issued by the Mars 'weather team' comes surprising news: during the freezing Martian winter the atmosphere above the planet’s South Pole is considerably warmer than predicted.

Mars Science Laboratory: Still Alive, For Now

The Mars Science Laboratory, the next generation of Mars rovers slated to head to Mars in 2009, is still alive, for the time being. The car-sized rover designed to look for life on Mars is over budget and behind schedule due to technical problems, and NASA officials met today to discuss their options. Potentially, Congress could pull the plug on the mission if cost overruns go too high. NASA Administrator Mike Griffin and Science Associate Administrator Ed Weiler were briefed, and met with mission managers in attempt to work out a potential solution. In a press briefing today, Doug McCuistion, director of the Mars Exploration Program at NASA headquarters said the rover's progress will be assessed again in January, but the mission will need more money.

Precious Gems Discovered on Mars

The discovery of a water-based mineral on Mars by the spectrometer on board the Mars Reconnaissance Orbiter suggests liquid water remained on the planet's surface a billion years later than was previously thought, and it likely played an important role in shaping the planet's surface and possibly hosting life. Hydrated silica, commonly known as opal, has been found across large region of Mars. "This is an exciting discovery because it extends the time range for liquid water on Mars, and the places where it might have supported life," said Scott Murchie, the principal investigator for the Compact Reconnaissance Imaging Spectrometer for Mars (CRISM) at the Johns Hopkins University Applied Physics Laboratory in Laurel, Md. "The identification of opaline silica tells us that water may have existed as recently as 2 billion years ago.

Energizer-Bunny Odyssey Spacecraft Will Keep Going

Seems like everyone at Mars is getting an extended mission these days – every spacecraft, that is. The Mars Odyssey orbiting spacecraft, the longest-serving of six spacecraft now studying Mars, has gotten another two-year extension of its mission. And mission extensions are great opportunities to try something new, so Odyssey is altering its orbit to get a different and better look at Mars with its Thermal Emission Imaging System which maps minerals on Mars in infrared. During this third mission extension, which goes through September 2010, Odyssey will also be able to point its camera with more flexibility than ever before. Odyssey is another Energizer Bunny-like spacecraft: it has been going and going since it reached Mars in 2001.

Reveal the Mars Phoenix's Classified Discoveries With Photoshop

The Mars Phoenix said goodbye last week. It's very sad, like the end of Wall-E. Publicly, the Mars Phoenix was sent to study the planet's water history and whether it could have ever supported life. But we've all seen enough sci-fi movies involving the government to know that there's probably more to it than that, especially if Tommy Lee Jones is involved. So, use Photoshop to show us what the Mars Phoenix really discovered that the government doesn't want us to know about. Here's some Mars Phoenix images to get started.

NASA Selects Mission to Study Mars Atmosphere

WASHINGTON, Sept. 15 /PRNewswire-USNewswire/ -- NASA has selected a Mars robotic mission that will provide information about the Red Planet's atmosphere, climate history and potential habitability in greater detail than ever before. Called the Mars Atmosphere and Volatile EvolutioN (MAVEN) spacecraft, the $485 million mission is scheduled for launch in late 2013. The selection was evaluated to have the best science value and lowest implementation risk from 20 mission investigation proposals submitted in response to a NASA Announcement of Opportunity in August 2006. "This mission will provide the first direct measurements ever taken to address key scientific questions about Mars' evolution," said Doug McCuistion, director of the Mars Exploration Program at NASA Headquarters in Washington.

TV Alert: Five Years on Mars

On Sunday evening Nov. 2, at 7 pm CST,(in the US; check your local listings) the National Geographic channel will be showing a special documentary on the Mars Exploration Rovers. It's called "Five Years on Mars," and dramatizes the trials and tribulations of the rovers Spirit and Opportunity and highlights new scientific information on the planet’s geology and water history. If you saw the "Mars: Dead or Alive" and "Welcome to Mars" shows, this one should be even better. The show will feature photo-realistic animation based on the actual landscape as captured by the rovers’ cameras, and interviews with MER PI Steve Squyres and others on the rover team.

Phoenix Lander Will Listen to the Sounds of Mars

We may be able to hear, for the first time, what it sounds like on the surface of Mars. The Phoenix Lander has a microphone on board, which will be switched on in upcoming days of operations. "This is definitely a first," said Phoenix principal investigator Peter Smith. The microphone is a part of the Mars Descent Imager (MARDI) system on the underside of the lander designed to take images of Mars' surface during the lander's descent. However, the system was never used. Tests of the system during the flight to Mars revealed the possibility that using it might cause other parts of the landing system to not function correctly. But using it later wasn't ruled out. So, after updated software is sent to the lander, the microphone will be turned on.
