Rover Exiting Crater To Continue Martian Marathon

Thu, 28 Aug 2008 15:27:50 +0000

Riding with Robots writes "The robotic geologist Opportunity has nearly reached the rim of Victoria Crater, which it is leaving after a year of exploration inside. Rover handlers decided to abandon attempts to approach the crater's cliff walls when they saw a power spike similar to the one that preceded a broken wheel on its twin, Spirit. Opportunity is already making do with a stuck robotic arm. The mission's manager said, 'Both rovers show signs of aging, but they are both still capable of exciting exploration and scientific discovery.' Opportunity is set to continue trekking across the Meridiani Plains of Mars, even though its wheels have already seen 10 times the use they were designed for. Meanwhile, Spirit has survived yet another harsh Martian winter to produce another striking panorama." Adam Korbitz notes other Mars-related news that funding has been approved for the Search for Extra-Terrestrial Genomes (SETG) Project. The project was one of 15 selected to receive funds through a NASA research opportunity program. The stated goal of the proposal is to "develop a PCR detector for in situ analysis on other planets, most immediately, Mars. This instrument is so sensitive it should allow the detection very low levels of microbial life on Mars, and will determine its phylogenetic position by analysis of the DNA sequence of the genes detected in situ."

Mars Soil Frustrates Phoenix Again

Mon, 28 Jul 2008 01:11:17 +0000

Tablizer writes "The Phoenix Mars lander has been frustrated yet again by Mars' odd soil. The wet nature of the soil they are targeting appears to have made it get stuck in the scoop rather than drop into the oven. Past problems with similarly clumpy soil may have damaged the lander because the vibrator had to be used longer than designed, resulting in a short circuit."

xaositects writes "Now I know all of you have your 3D glasses from 1985 still, so don them once again to check out these cool 3D images of Mars's Arctic landscape from the Phoenix Lander's stereoscopic imager. There are also a few close-ups of the parts of Phoenix that are in view and a link to more pictures on the Phoenix Image Gallery."

Water Ice On Mars

Sun, 22 Jun 2008 23:07:31 +0000

cathector sends along a story from SpaceWeather.com on the discovery of water ice on Mars. "Scientists have figured out the mysterious white substance unearthed by NASA's Phoenix lander on Mars. It's frozen water. The breakthrough came last week when Phoenix's stereo camera caught the substance in the act of disappearing. Bathed in martian sunlight for four days, the white substance sublimated — i.e., it transformed from solid to gas without passing through the liquid state. This is how water behaves on Mars.... Some readers have asked, how do we know the white substance is not frozen CO2 (dry ice) instead of frozen water? Answer: Phoenix's landing site is too warm for dry ice. The average daily temperature is about -70 F while dry ice requires temperatures lower than about -109 F." The animated GIF showing the ice sublimating is pretty nice too.

The Mars Phoenix Twitters?

Tue, 10 Jun 2008 06:57:08 +0000

In all the bad press of Twitter lately, here is a good reason to use it. The Mars Phoenix Lander is Twittering. The Jet Propulsion Laboratory (JPL) set up the account to keep the legions of followers up to date. It not only gives updates but also answers questions about it's interplanetary soil-digging device.

Phoenix Mars Lander Deploys Robotic Arm, Possibly Finds Ice

Fri, 30 May 2008 23:37:13 +0000

The Phoenix Mars Lander has successfully deployed its robotic arm and tested other instruments including a laser designed to detect dust, clouds, and fog. The arm will be used to dig up samples of the Martian surface which will be analyzed as a possible habitat for life. A camera on the arm will allow pictures to be taken of the ground directly beneath the lander. The camera has already seen what may be ice, which was exposed when the soil was disturbed by the landing. The data collected by the arm will be compared to recent findings which suggest that water on Mars may have been too salty for most known forms of life.

First Pictures From Mars Phoenix Lander

Mon, 26 May 2008 13:46:08 +0000

Now that the solar panels have been deployed, the Mars Phoenix Lander has begun sending back pictures of the red planet to the hungry space geeks of earth. In just a few weeks the claw will deploy and they'll start digging a hole. The scientists expect to use the dirt to construct a little sand castle which they will defend with several GI Joe action figures, and a bald barbie stolen from their sisters. Oh, and maybe find water or bacteria.

Phoenix Mars Lander To Touch Down In 2 Hours

Sun, 25 May 2008 21:59:02 +0000

AFP has a good summary of the pre-touchdown jitters the Phoenix Mars Lander crew is living through. The spacecraft has been under way for 10 months. If the landing goes according to plan — and only about half of the three dozen such attempts have — mission controllers at the University of Arizona will receive radio signals from the Martian surface at 23:53 GMT. Here's the Mars mission home. You can (in theory) track the lander here, but at the moment the JPL Solar System Simulator is "experiencing technical difficulties."

NASA Phoenix Mission Ready For Mars Landing

Wed, 14 May 2008 09:40:16 +0000

Several readers relayed the press release from JPL about the upcoming landing of NASA's Phoenix Mars Lander on May 25. It's going to set down in the north polar regions and look for indications of whether conditions have even been favorable for microbial life. "Phoenix will enter the top of the Martian atmosphere at almost 21,000 kilometers per hour... In seven minutes, the spacecraft must complete a challenging sequence of events to slow to about 8 kilometers per hour... before its three legs reach the ground. Confirmation of the landing could come as early as 7:53 p.m. EDT. 'This is not a trip to grandma's house. Putting a spacecraft safely on Mars is hard and risky,' said Ed Weiler, associate administrator for NASA's Science Mission Directorate. 'Internationally, fewer than half the attempts have succeeded.'"

Evidence Of Glaciers On Mars Suggests Recent Climate Activity

Wed, 23 Apr 2008 23:02:26 +0000

Last year, the Mars Reconnaissance Orbiter captured high-resolution images of the Red Planet which showed many mesas, valleys, and rock debris which appeared to be (geologically speaking) recent formations. A team of scientists from Brown University analyzed the photographs and found evidence that the terrain was carved by large glaciers much more recently than they thought possible. Climate activity on Mars was thought to have quieted over 3 billion years ago, but these glaciers would have been around within the last 10-100 million years. "The finding could have implications for the life-on-Mars argument by strengthening the case for liquid water. Ice can melt two ways: by temperature or by pressure. As currently understood, the Martian climate is dominated by sublimation, the process by which solid substances are transformed directly to vapor. But ice packs can exert such strong pressure at the base to produce liquid water, which makes the thickness of past glaciers on its surface so intriguing."

Will Mars be a One-way Trip?

Thu, 06 Mar 2008 01:56:33 +0000

alexj33 writes "Will humans ever really go to Mars? Let's face it, the obstacles are quite daunting. Not only are there numerous, difficult, technical issues to overcome, but the political will and perseverance of any one nation to undertake such an arduous task is huge. However, one former NASA engineer believes a human mission to Mars is quite possible, and such an event would unify the world as never before. But Jim McLane's proposal includes a couple of major caveats: the trip to Mars should be one-way, and have a crew of only one person." Read more of this story at Slashdot.

Meet the Drivers Behind NASA's Mars Rovers

Fri, 16 Nov 2007 20:23:18 +0000

StonyandCher writes "Scott Maxwell must have one of the best IT jobs in the solar system, driving NASA's Mars Rovers. Behind every robot is a driver. He's one of 14 Rover Drivers that work in NASA's California-based Jet Propulsion Laboratory. Maxwell discusses what makes up an average work day, the highlights of the project, how he got the job, and the tools he uses in his work. A great look at the team of dedicated IT workers behind the robots, plotting the every move of NASA's twin robot geologists, Spirit and Opportunity, since they first landed on Mars at the start of 2004."

Potential Landing Sites for EU Mars Rover Selected

Fri, 16 Nov 2007 16:21:09 +0000

kfz versicherung writes "In 2013 the European Space Agency will launch its mission to Mars - ExoMars. The multi-million-euro mission calls for a rover weighing just over 200kg that can trundle over the martian soil in search of past and present life. Now prime landing spots have been selected. The list includes two sites at Meridiani Planum, the flat expanse near Mars' equator where Nasa's Opportunity found possible evidence for an ancient sea. Early in Earth's history, all the primordial biochemistry took place in phyllosilicates, some kind of mineral that is a good matrix for preserving organic matter. Scientists are guessing that a similar site is the best place to start looking for fossil life on the Red Planet." Read more of this story at Slashdot.
