Nasa check for 'unlikely' survival of Mars lander
Nasa's Mars Odyssey orbiter is set to listen for possible radio transmissions from the Phoenix Mars lander, to check if it has survived the Martian winter. The agency said that communication from the lander was "extremely unlikely". Phoenix's last communication was on 2 November 2008, after it completed its study of an arctic Martian site. Since then, this landing site has gone through autumn, winter and part of spring, and Phoenix was not designed to survive such temperature extremes. Its electronics are likely to have broken up as temperatures plummeted. But, just in case, Odyssey will pass over the Phoenix landing site approximately 10 times each day during three consecutive days of listening, beginning on 18 January. It will undertake two longer "listening campaigns" in February and March. |

Mars' ancient lake beds spied by Nasa probe
New images of Mars suggest the Red Planet had large lakes on its surface as recently as three billion years ago. The evidence comes from Nasa's Mars Reconnaissance Orbiter (MRO) which spied a series of depressions linked by what look like drainage channels. Scientists tell the journal Geology that the features bear the hallmarks of being produced by liquid water.But they appear to have formed much later in Mars' history than many thought possible, the researchers add. The team, from Imperial and University Colleges London, studied pictures of several flat-floored depressions located above Ares Vallis, a giant gorge running some 2,000km across Mars' equator.The hollows are about 20km in diameter. |

| Tests on Earth to Help Free Spirit Rover on Mars: Live Webcast, Chat The team that operates rovers on Mars is using a test rover in southern California to assess maneuvers the Mars rover Spirit might use to get out of soft, loose soil where its wheels have sunk hub-deep. A live videocast and chat from NASA's Jet Propulsion Laboratory, Pasadena, Calif., will give viewers a chance to ask questions of rover team members working to get Spirit rolling again. The live event will air on the "NASAJPL" channel available on Ustream Web TV at: http://www.ustream.tv/channel/nasajpl on Thursday, July 23, beginning at 3 p.m. PDT (6 p.m. EDT and 2200 UTC). |

Human on Mars Next Big Mission?
While some of the Apollo astronauts are suggesting putting humans on Mars is the next big challenge for NASA, one expert says there's a lot to be worked out first. Hugh Kieffer is a consultant for NASA and Genoa resident. In current dollars the entire Apollo program is estimated to have a $150 billion dollar price tag in current dollars. Kieffer says going to Mars would also come with a hefty bill. "The cost will be substantially larger than the best estimates before the project starts." |

Spirit and its twin, Opportunity, landed on Mars in January 2004 for what were planned as three-month missions to study sites on opposite sides of the planet. Both are still active and returning streams of scientific information. Spirit has not driven since May 6, 2009, when it had become partially embedded in the soil. To minimize the risk of worsening Spirit's predicament, operators decided to conduct a series of experiments with a test rover before driving Spirit again. |

  NASA Launches 'Free Spirit' Web Site for Stuck Mars Rover
NASA's Jet Propulsion Laboratory has launched Free Spirit, a Web site dedicated to keeping track of the agency's efforts to free the stuck rover on the surface of Mars, Space.com reports. NASA currently has an entire team of engineers working to simulate the rover's predicament using a test rover and several tons of simulated Mars dirt.
"People really like the whole 'free Spirit,' idea and we thought we should make it really easy for people to find updates," said Veronica McGregor, a NASA spokesperson at JPL, in the article. "In a way, we're trying to make it a campaign that everyone can get involved in."

| One Mars Rover Sees a Distant Goal; The Other Takes a New Route PASADENA, Calif. -- On a plain that stretches for miles in every direction, the panoramic camera on NASA's Mars rover Opportunity has caught a first glimpse on the horizon of the uplifted rim of the big crater that has been Opportunity's long-term destination for six months. Opportunity's twin, Spirit, also has a challenging destination, and last week switched to a different route for making progress. Endeavour Crater, 22 kilometers (14 miles) in diameter, is still 12 kilometers (7 miles) away from Opportunity as the crow flies, and at least 30 percent farther away on routes mapped for evading hazards on the plain. Opportunity has already driven about 3.2 kilometers (2 miles) since it climbed out of Victoria Crater last August after two years of studying Victoria, which is less than one-twentieth the size of Endeavour. |
