Phoenix transmitted a 360-degree panorama of its frigid Martian world, freed its nearly 8-foot robotic arm, tested a laser instrument for studying dust and clouds, and transmitted its second weather report on Wednesday evening.
Commands were communicated to Phoenix to rotate the robotic arm's wrist to unlatch its launch lock, raise the forearm and move it upright to release the elbow restraint.
"We're pleased that we successfully unstowed the robotic arm. In fact, this is the first time we have moved the arm in about a year," said Matthew Robinson of NASA's Jet Propulsion Laboratory in Pasadena, Calif. The arm deployment brings the Phoenix mission to a significant milestone.
"We have achieved all of our engineering characterization prerequisites, with all the critical deployments behind us," said JPL's Barry Goldstein, Phoenix project manager. "We're now at a phase of the mission where we're characterizing the science payload instruments. That's a very important step for us."After a health check that tests the arm at a range of warmer and colder temperatures, the titanium and aluminum arm will soon be tasked with its first
assignment: to use its camera to look under the spacecraft to assess the terrain and underside of the lander.
The robotic arm will later trench into the icy layers of northern polar Mars and deliver samples to instruments that will analyze what this part of Mars is made of, what its water is like, and whether it is or has ever been a possible habitat for life.
Another milestone for the mission included the activation of the laser instrument called light detection and ranging instrument, or lidar.
"The Canadians are walking on moonbeams. It's a huge achievement for us," said Jim Whiteway Canadian Science lead from York University, Toronto. The lidar is a critical component of Phoenix's weather station, provided by the Canadian Space Agency. The instrument is designed to detect dust, clouds and fog by emitting rapid pulses of green laser-like light into the atmosphere. The light bounces off particles and is reflected back to a telescope.
"One of the main challenges we faced was to deliver the lidar from the test lab in Ottawa, Canada, to Mars while maintaining its alignment within one one-hundredth of a degree," said Whiteway. "That's like aiming a laser pointer at a baseball at a distance from home plate to the center field wall, holding that aim steady after launch for a year in space, then landing," he added.
Lidar data shows dust aloft to a height of 3.5 kilometers (2 miles). The weather at the Phoenix landing site on the second day following landing was sunny with moderate dust, with a high of minus 30 degrees Celsius (minus 22 degrees Fahrenheit) and a low of minus 80 (minus 112 degrees Fahrenheit).The Phoenix mission is led by Smith at the University of Arizona with project management at JPL and development partnership at Lockheed Martin, Denver.
International contributions come from the Canadian Space Agency; the University of Neuchatel, Switzerland; the universities of Copenhagen and Aarhus, Denmark; Max Planck Institute, Germany; and the Finnish Meteorological Institute.

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.
The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...

Nanometer-scale magnetic perforated grids could create new possibilities for computing. Together with international colleagues, scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) have shown how a cobalt grid can be reliably programmed at room temperature. In addition they discovered that for every hole ("antidot") three magnetic states can be configured. The results have been published in the journal "Scientific Reports".
Physicist Dr. Rantej Bali from the HZDR, together with scientists from Singapore and Australia, designed a special grid structure in a thin layer of cobalt in...
