More Frost on Mars Phoenix Lander
More early morning frost is showing up on the Phoenix spacecraft. The Surface Stereo Imager (SSI) took several pictures of the "Telltale" on the Phoenix Mars Lander, the device used to measure wind velocities at the landing site on Mars and created a movie of bright specks of frost accumulating on the mirror of [...]

Phoenix Camera Snaps Frost on Mars
It's getting a little nippy in the mornings on Mars. The Phoenix lander's Surface Stereo Imager took this image at 6 a.m. on Sol 79 (August 14, 2008 here on Earth), and a thin layer of water frost is visible on the ground around the landing area. From subsequent images, the frost begins [...]

Mars Dust Grains Imaged by Atomic Force Microscope
What is Mars ubiquitous dust really like, close-up? Scientists from the Phoenix missions are finding out with the Atomic Force Microscope (AFM), an instrument that is providing the highest magnification of anything seen from another world. A couple of months ago the Phoenix Mars Lander used its optical microscope to image small grains [...]

Evidence for Widespread Water on Early Mars
Images and data from the Mars Reconnaissance Orbiter (MRO) have revealed layers of clay-rich rock that suggests abundant water was once present on Mars. Scientists from the SETI Institute, the Jet Propulsion Laboratory and several universities have been studying data focused on the Mawrth Vallis area on Mars’ northern highland region. This is [...]

Perchlorate on Mars Could be Potential Energy Source for Life; Phoenix Team Fires Back at Alligations
It's been a busy few days for the Phoenix Mars lander rumour-mill. On Friday, an article was published in Aviation Week reporting an undisclosed source from the NASA team analysing results from the Microscopy, Electrochemistry, and Conductivity Analyzer (MECA) had come forward saying Phoenix scientists were in communication with the White House. Apparently there had [...]

The White House is Briefed: Phoenix About to Announce "Potential For Life" on Mars
It would appear that the US President has been briefed by Phoenix scientists about the discovery of something more "provocative" than the discovery of water existing on the Martian surface. This news comes just as the Thermal and Evolved Gas Analyzer (TEGA) confirmed experimental evidence for the existence of water in the Mars regolith on [...]

Latest from HiRISE: Stairs, Polygons, Dunes and Troughs
Meridiani Planum on Mars, where the Mars Rover Opportunity has been traversing the past four plus years, is not just covered with flat, endless plains. Of course, Opportunity has been entering and studying a few of the craters in the region. Here's a crater in Meridiani that's a whopper. This image from [...]

"We Have Water" on Mars, TEGA Test Confirms
The Phoenix Mars lander finally was successful in delivering a fairly fresh sample of Martian soil to the Thermal and Evolved Gas Analyzer (TEGA) oven on Wednesday and a "bake and sniff" test identified water in the soil sample. "We have water," said William Boynton of the University of Arizona, lead scientist for TEGA. [...]

Phobos Up Close from Mars Express
On July 23, Europe's Mars Express spacecraft flew only 93 kilometers from Mars' moon Phobos, and took the most detailed images ever of the small, irregular moon. Additionally, the spacecraft made other close flybys during the past few weeks, and creating a variety of images. The moon's grooved surface can be seen in [...]

Area Beneath Phoenix Lander Is Changing
The bright, hard surface feature beneath the Phoenix Mars Lander has visibly changed from when it was first imaged shortly after the lander touched down on the Red Planet. Scientists believe the area, called "Snow Queen" could possibly be ice. Thruster exhaust blew away surface soil covering Snow Queen as Phoenix landed, exposing [...]

Mars' Sticky Soil Strikes Again
NASA's Phoenix Mars Lander scraped up some icy soil with its robotic arm and scoop and then attempted to quickly deliver the sample to the oven on board. But not enough soil made it to the oven; the icy soil stuck to the scoop. Engineers determined the rasping and scraping activity collected a [...]

Phoenix in the Land of Mars' Midnight Sun
This panorama mosaic of images was taken by the Surface Stereo Imager on board NASA's Phoenix Mars Lander. This mosaic documents the midnight sun during several days of the mission, from Sol 46, or the 46th day of the mission to Sol 56 (that would be to July 12 - 22, 2008 here on Earth.) [...]

Phoenix Lander Couldn't Sleep At All Last Night
For the first time, the Phoenix lander stayed up all night. But there was no partying for the little lander, just hard work. Phoenix coordinated its schedule to work together with the Mars Reconnaissance Orbiter to make joint observations to study Mars' atmosphere. More on that in a minute, [...]

Mars Arctic in 3D from Phoenix
OK, everyone: get out your funky 3-D glasses for a whole new look at Mars! We've seen the smooth plains of Meridiani from Opportunity in 3-D; we've gazed upon the rocky terrain of Gusev Crater from Spirit in more than two dimensions. But now it's time to feast your eyes on Mars' [...]
