Tiny ovens are expected to begin testing soil samples on the Martian North Pole this week. In its seventh day on Mars, the Phoenix Mars Lander successfully deployed its shovel and dug a sample of dirt. A close-up, enhanced photo of the sample showed traces of white materials, a promising development for the expedition.
"That bright material might be ice or salt. We're eager to do testing of the next three surface samples collected nearby to learn more about it," says Ray Arvidson of Washington University in St. Louis, Phoenix co-investigator for the robotic arm.
The shovel deployment came later than expected, heightening tension at missions headquarters at the Jet Propulsion Laboratory in Pasadena, CA. There were fears a plastic casing around the shovel had been damaged in the landing. But the shovel did eventually successfully deploy.
Instruments on board have been tested since the vehicle landed May 25. There was a glitch with the Thermal and Evolved Gas Analyzer. Tests on Thursday, May 29 showed electrical behavior consistent with an intermittent short circuit in the spectrometer portion of TEGA. The mass spectrometer will be used to examine vapors given off by heat from the soil samples. "We have developed a strategy to gain a better understanding of this behavior, and we have identified workarounds for some of the possibilities," says William Boynton of the University of Arizona, Tucson, lead scientist for the instrument.
By experimenting with the photovoltaic reaction in solar cells, researchers at MIT have made a breakthrough in energy efficiency that significantly pushes the boundaries of current commercial cells on the market.
In a world that's going green, industrial operations have a problem: Their processes involve materials that are potentially toxic, flammable, corrosive, or reactive. If improperly managed, this can precipitate dangerous health and environmental consequences.
A quick look into the merger of two powerhouse 3D printing OEMs and the new leader in rapid prototyping solutions, Stratasys. The industrial revolution is now led by 3D printing and engineers are given the opportunity to fully maximize their design capabilities, reduce their time-to-market and functionally test prototypes cheaper, faster and easier. Bruce Bradshaw, Director of Marketing in North America, will explore the large product offering and variety of materials that will help CAD designers articulate their product design with actual, physical prototypes. This broadcast will dive deep into technical information including application specific stories from real world customers and their experiences with 3D printing. 3D Printing is
