Opportunity Bids Farewell To Victoria![]() Opportunity has completed one of the most fantastic scientific campaigns of the Mars Exploration Rover mission -- the interior investigation of "Victoria Crater." After spending more than 340 Martian days, known as sols -- almost one Earth year -- inside the crater, Opportunity climbed back out on sol 1634 (Aug. 28, 2008). To do so, Opportunity retraced the wheel tracks the robotic ... more NASA's Phoenix Lander In A Whirlwind ![]() NASA's Phoenix Mars Lander has photographed several dust devils dancing across the arctic plain this week and sensed a dip in air pressure as one passed near the lander. These dust-lofting whirlwinds had been expected in the area, but none had been detected in earlier Phoenix images. The Surface Stereo Imager camera on Phoenix took 29 images of the western and southwestern horizon on Sept ... more Looking For Life On Mars - In A Canadian Lake ![]() On the surface, Pavilion Lake, nestled among the peaks of Canada's Marble Range, looks like a thousand other mountain lakes. It's not unusually large or deep. It's not especially acidic, or alkaline; it's not overly salty; nor are there high concentrations of minerals dissolved in its water. Locals come here to fish, to boat, to swim, and to watch the summer clouds drift by. But underwater ... more Next Mars Soil Scoop Slated For Last Wet Lab Cell ![]() The next soil sample that NASA's Phoenix Mars Lander will deliver to its deck instruments will go to the fourth of the four cells of Phoenix's wet chemistry laboratory, according to the Phoenix team's current plans. The chosen source for that sample is from the "Snow White" trench on the eastern end of the work area reachable with Phoenix's robotic arm. In July that trench yielded a ... more Underneath Phoenix Lander 97 Sols After Touchdown ![]() The Robotic Arm Camera on NASA's Phoenix Mars Lander took this image on Sept. 1, 2008, at about 4 a.m. local solar time during the 97th Martian day, or sol, since landing. The view underneath the lander shows growth of the clumps adhering to leg strut (upper left) compared with what was present when a similar image was taken about three months earlier. The view in this Sol 97 image is south ... more |

![]() ![]() A fork-like conductivity probe has sensed humidity rising and falling beside NASA's Phoenix Mars Lander, but when stuck into the ground, its measurements so far indicate soil that is thoroughly and perplexingly dry. "If you have water vapor in the air, every surface exposed to that air will have water molecules adhere to it that are somewhat mobile, even at temperatures well below freezing ... more Opportunity To Exit Victoria Crater ![]() Like a backpacker hiking up a steep grade, Opportunity has been trying to gain elevation using a "switchback" approach inside "Victoria Crater." The rover's goal was to zigzag back and forth across a steep slope toward an outcrop nicknamed "Nevada," where scientists had hoped to do scientific analysis and collect high-resolution, panoramic images of the cliff face known as "Cape Verde." ... more Billion-dollar European probe set for asteroid encounter ![]() Far from Earth, a robot spacecraft has been prodded from deep slumber to make a rare encounter with an asteroid, the intriguing orbital debris that could offer clues into the making of the Solar System. The pride of the European Space Agency (ESA), the probe Rosetta has been ordered out of hibernation four and a half years into a 10-year trek that will take it into the dark chill of deep ... more Phoenix Mission Conducting Extended Activities On Mars ![]() NASA's Phoenix Mars Lander, having completed its 90-day primary mission, is continuing its science collection activities. Science and engineering teams are looking forward to at least another month of Martian exploration. Due to the spacecraft's sufficient power and experiment capacity, NASA announced on July 31 that the mission would continue operations through Sept. 30. Once the lander ... more |

![]() ![]() Hans Amundsen is a Norwegian geologist and the expedition leader of AMASE (Arctic Mars Analog Svalbard Expedition). AMASE is an international, interdisciplinary scientific research project that since 2003 has traveled to Svalbard, a group of islands in the High Arctic that provides some of the best sites on Earth for doing Mars-related field research. Among the most valuable geologic ... more Taking The Opportunity To Escape From Crater Victoria ![]() NASA's Mars Exploration rover Opportunity is heading back out to the Red Planet's surrounding plains nearly a year after descending into a large martian crater to examine exposed ancient rock layers. Opportunity will continue its mission to characterize the environment of Mars and help scientists determine if the planet could have been a habitat for past life in our solar system. "We've do ... more Phoenix Mission Conducting Extended Activities On Mars ![]() NASA's Phoenix Mars Lander, having completed its 90-day primary mission, is continuing its science collection activities.

Once the lander ... more NASA Mars Rover Opportunity Ascends To Level Ground ![]() NASA's Mars Exploration Rover Opportunity has climbed out of the large crater that it had been examining from the inside since last September. "The rover is back on flat ground," an engineer who drives it, Paolo Bellutta of NASA's Jet Propulsion Laboratory, announced to the mission's international team of scientists and engineers. Opportunity used its own entry tracks from nearly a ... more
