06.19.08 - Dice-size crumbs of bright material have vanished from inside a trench where they were photographed by NASA's Phoenix Mars Lander four days ago, convincing scientists that the material was frozen water that vaporized after digging exposed it.
05.25.08 - Landing Day!
05.19.08 - Welcome to the kick-off entry for the Phoenix entry, descent and landing (EDL) blog from the Jet Propulsion Laboratory in Pasadena, CA.
06.17.08 - One of the ovens on Phoenix continued baking its first sample of Martian soil over the weekend, while the Robotic Arm dug deeper into the soil to learn more about white material.
06.16.08 - One of the ovens on Phoenix continued baking its first sample of Martian soil over the weekend, while the Robotic Arm dug deeper into the soil to learn more about white material.
06.13.08 - New observations from Phoenix provide the most magnified view ever seen of Martian soil, showing particles clumping together even at the smallest visible scale.
06.12.08 - NASA's Phoenix Mars Lander has filled its first oven with Martian soil.
06.11.08 - NASA's Phoenix Mars Lander has filled its first oven with Martian soil.
06.10.08 - The team operating Phoenix plans to instruct the spacecraft in the next few days to use its Robotic Arm to sprinkle a spoonful of Martian soil onto a wheel that will rotate the sample into place for viewing by the spacecraft's Optical Microscope.
06.09.08 - Engineers operating the Robotic Arm on NASA's Phoenix Mars Lander are testing a revised method for delivering soil samples to laboratory instruments on Phoenix's deck now that researchers appreciate how clumpy the soil is at the landing site.
06.08.08 - On Sunday, Sol 14 of NASA's Phoenix Mars Lander mission, mechanical shakers inside the Thermal and Evolved-Gas Analyzer will attempt to loosen clumped soils on the device's screens to allow material to fall into the oven for analysis later in the week.
06.07.08 - The arm of NASA's Phoenix Mars Lander released a handful of clumpy Martian soil onto a screened opening of a laboratory instrument on the spacecraft Friday, but the instrument did not confirm that any of the sample passed through the screen.
06.06.08 - NASA's Phoenix Mars Lander made its first dig into Martian soil for science studies and is poised to deliver the scoopful to a laboratory instrument on the lander deck.
06.05.08 - A microscope on NASA's Mars Phoenix Lander has taken images of dust and sand particles with the greatest resolution ever returned from another planet.
06.04.08 - Two practice rounds of digging and dumping the clumpy soil at the Martian arctic site this week gave team members confidence to begin using Phoenix's Robotic Arm to deliver soil samples to instruments on the lander deck.
06.03.08 - Engineers and scientists operating NASA's Phoenix Mars Lander decided early today to repeat a practice test of releasing Martian soil from the scoop on the lander's Robotic Arm.
06.02.08 - One week after landing on far-northern Mars, NASA Phoenix spacecraft lifted its first scoop of Martian soil as a test of the lander's Robotic Arm.
06.01.08 - NASA's Phoenix Mars Lander reached out and touched the Martian soil for the first time on Saturday, May 31, the first step in a series of actions expected to bring soil and ice to the lander's experiments.
05.31.08 - A view of the ground underneath NASA's Phoenix Mars Lander adds to evidence that descent thrusters dispersed overlying soil and exposed a harder substrate that may be ice.
05.30.08 - Scientists have discovered what may be ice that was exposed when soil was blown away as NASA's Phoenix spacecraft landed on Mars last Sunday, May 25.
