100 Days From Mars

At 10:31 p.m. PDT on April 27 NASA's Mars Science Laboratory, carrying the one-ton Curiosity rover, was within 100 days from its appointment with the Martian surface. At that moment, the mission had about 119 million miles (191 million kilometers) to go and was closing at a speed of 13,000 mph (21,000 kilometers per hour).

Mars Express Gravity Results

Five years of Mars Express gravity mapping data are providing unique insights into what lies beneath the Red Planet's largest volcanoes. The results show that the lava grew denser over time and that the thickness of the planet's rigid outer layers varies across the Tharsis region.

A Washington State University astrobiologist is leading a group of 20 scientists in calling for a mission to Mars with "a strong and comprehensive life detection component." At the heart of their proposal is a small fleet of sensor packages that can punch into the Martian soil and run a range of tests for signs of ancient or existing life.

Life After Mars

Seventeen months of isolation on a simulated trip to Mars came to an end five months ago. Their mission was over and they breathed fresh air again. What have ESA 'marsonauts' Diego Urbina and Romain Charles been doing since they left their 'spacecraft'?

At last week's media telecon NASA representatives stressed that this review process and this meeting were going to be "transparent and open" and that people from outside NASA would be encouraged to attend. This does not synch with the meeting description that has been posted.

This image covers a region of Mars near Nili Fossae that contains some of the best exposures of ancient bedrock on Mars. The enhanced-color subimage shows part of the ejecta from an impact crater.

Mars: Summer is on Its Way

These dark sand dunes in the North polar region, basking in the sunshine of late spring, have shed most of their seasonal layer of winter ice. A few bright ice deposits remain sequestered in "cold traps" shadowed from the sun on the poleward-facing side of the dunes.

ESA: The latest images released from ESA's Mars Express reveal a series of 'pit-chains' on the flanks of one of the largest volcanoes in the Solar System. Depending on their origin, they might be tempting targets in the search for microbial life on the Red Planet.

Sols 2901-2906, March 22-27, 2012: Opportunity is positioned on the north end of Cape York on the rim of Endeavour Crater with an approximate 15-degree northerly tilt for favorable solar energy production.

If you have to chose just one night in April to go out and look at the stars, NASA scientists say it should be April 21st when the Lyrid meteor shower from the Comet Thatcher peaks. This week's ScienceCast explains what makes that one night so special.

NASA CTO Peck Visits Pasadena's Honeybee Robotics Wednesday

"NASA Chief Technologist Mason Peck will visit Honeybee Robotics in Pasadena, Calif., on Wednesday, March 14. Peck's visit will highlight how government can partner with small business to help create the jobs of the future through investment in science and technology. Honeybee Robotics has been a technology supplier to the last three Mars missions. It has received multiple NASA Small Business Innovation Research (SBIR) awards to develop mechanisms that could be used on future NASA missions, many of which also have potential in the commercial marketplace. These include excavation and drilling tools for potential use in harsh environments on Earth and other planets."

Hacking Curiosity: Adding an aftermarket sample collection capability to the Mars Science Lab, Doug Mohney

"NASA's withdrawal from a joint ExoMars 2016/2018 mission has left the planetary science community grieving the at loss of the first step in a sample return mission: collection of samples. However, there's a $2.5 billion rover with a mechanical arm and plenty of power scheduled to land on Mars in August. Can the Mars Science Lab (MSL) Curiosity be fitted with a couple of "aftermarket" sample collection racks once it completes its primary mission of one Martian year? The author believes there is the potential to do so."

Jim Rice, NASA Mars Landing Site Specialist

"Jim Rice, now a veteran of the site-selection process, got his first taste in 1994 with NASA's Mars Pathfinder mission. "I was just a graduate student then, and I can't tell you how excited I was," he says. "It was the first mission to land on Mars in more than 20 years, and my site was chosen for the landing!"

Orcus Patera is an enigmatic elliptical depression near Mars's equator, in the eastern hemisphere of the planet. Located between the volcanoes of Elysium Mons and Olympus Mons, its formation remains a mystery. A new image from the High Resolution Stereo Camera aboard ESA's Mars Express orbiter shows the unusual feature with unprecedented clarity.

A team of researchers from the CSIC-INTA Astrobiology Centre in Madrid has confirmed that the type of mineralogical composition on the surface of Mars influences the measuring of its temperature.
The outcome of the bilateral meeting was an agreement to create a Mars Exploration Joint Initiative (MEJI) that will provide a framework for the two agencies to define and implement their scientific, programmatic and technological goals at Mars.
