The Red Planet

(Newser) - NASA’s Phoenix Mars lander extended its robotic arm for the first time late last night, the AP reports, a day late because of a temporary radio blackout. The arm, which will unfurl over a 2-day period, will eventually be used to take samples of ice below the surface in Mars’ arctic regions to search for evidence of life. More »

(Newser) - The Mars Phoenix Lander is sending NASA the first photos of the red planet's northern polar region, CNN reports. On its 3-month mission, the lander will “taste and sniff the northern polar site’s soil and ice,” the agency said. The photos show brown polygons checkering the landscape as far as the eye can see.

(Newser) - The Phoenix probe has landed safely on Mars' icy surface and begun its search for life, Space.com reports. Exultant NASA scientists are now awaiting a second radio signal to see how much power it has left—a critical element of the mission. And they await the probe's first snapshots. "I can't wait for even that first look at the surface," the mission's main investigator said. More »

(Newser) - The latest NASA mission searching for signs of life on Mars comes to a heart-pounding climax Sunday as the Phoenix Lander attempts to touch down at the red planet's pole in a hunt for water. The lander must perform complex maneuvers in which the whole mission is at risk for a full 7 minutes, reports the Christian Science Monitor . More »

(Newser) - If a comet ever obliterates life on Earth, don't worry—space rocks could later fall in and reseed a few basic life forms. A new study shows that organisms can survive being hit by a meteor, ejected into space, and hurtled back to Earth on the face of a rock—which is good news should we ever go the way of the dinosaurs, Astrobiology reports.

(Newser) - Scientists have found what look like the remains of hot springs on Mars—a sign life could have existed there, reports the Washington Post . Sophisticated equipment returned images of “mounds” that appear remarkably similar to springs found in Australia, according to scientists. They appear to have dried up tens of millions of years ago--fairly recently, in planetary terms. More »

(Newser) - The first mammal on Mars may be a monkey. Russia is testing radiation and weightlessness effects on macaques for a possible trip to the red planet. Scientists also want to see how the animals react to isolation and the special diet the 520-day mission would require, reports the BBC. Twelve monkeys have been passengers on previous Soviet and Russian space flights. More »

(Newser) - NASA has spared its far-flung Mars rovers from budget cuts, reports the Washington Post, after its administrator got wind of the plan to hibernate Spirit and roll Opportunity back to part time. "Closing down either of the rovers is not on the table," his spokesman said, and underlings are looking elsewhere for cuts. More »

(Newser) - NASA confirmed and denied plans today to scuttle a Mars rover and fire 300 employees, CNN reports. The space agency first announced a $4 million cut to the Mars program's $20 million budget and vowed to unplug one of two rovers roaming the red planet. Then a NASA spokesman told CNN that "the cancellation of the Mars Exploration Rovers is not under consideration." More »
