"The oven is working very well and living up to our expectations," said Phoenix co-investigator Bill Boynton of the University of Arizona, Tucson. Boynton leads the Thermal and Evolved-Gas Analyzer (TEGA), or oven instrument, for Phoenix.
Phoenix has eight separate tiny ovens to bake and sniff the soil and look for volatile ingredients, such as water. This baking is performed at three different temperature ranges.
On Sol 18 (June 12), the lander's Robotic Arm dug deeper into the two trenches, informally called "Dodo" and "Goldilocks," where white material was previously found. This created one large trench, now called "Dodo-Goldilocks."
"We have continued to excavate in the Dodo-Goldilocks trench to expose more of the light-toned material, and we will monitor the site," said Robotic Arm lead scientist Ray Arvidson of the University of Washington, St. Louis. "If the material is ice, it should change with time. Frost may form on it, or it could slowly sublimate." Sublimation is the process where a solid changes directly into gas.
The Dodo-Goldilocks trench is 22 centimeters wide (8.7 inches) and 35 centimeters long (13.8 inches). The trench is seven to eight centimeters (2.7 to 3 inches) deep at its deepest. The deepest portion is closest to the lander.
The white material is located only at the shallowest part of the trench, farthest from the lander, indicating that it is not continuous throughout the excavated site. The trench might be exposing a ledge, or only a portion of a slab, of the white material, according to scientists.
The Phoenix mission is led by Peter Smith with project management at JPL and development partnership at Lockheed Martin, located in 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.MEDIA CONTACTS:

At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...
There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?
At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...

A team led by Austrian experimental physicist Rainer Blatt has succeeded in characterizing the quantum entanglement of two spatially separated atoms by observing their light emission. This fundamental demonstration could lead to the development of highly sensitive optical gradiometers for the precise measurement of the gravitational field or the earth's magnetic field.
The age of quantum technology has long been heralded. Decades of research into the quantum world have led to the development of methods that make it possible...
