Device to Measure Wind on Mars Will Soon be Landing
A University of Alberta researcher is counting down the days until the Phoenix Mars Lander spacecraft lands on Mars. He created an instrument on the lander called the Telltale. It will be used to measure winds in the polar region of Mars.
University of Alberta scientist Carlos Lange is still amazed that an instrument he dreamed up, a wind sensor called the Telltale, will soon be landing on Mars.
This is the first time Canadians have been involved with an interplanetary mission and Lange, a mechanical engineering professor, spent four years in preparation for this mission, including helping to create the Telltale, which is able to measure winds in the polar region of Mars. Mars is typically windy and learning more about this aspect of the planet’s climate will help scientists understand the cycle of water on the planet and identify possible zones that could sustain life.
“For all of us, this interplanetary Lander mission is an extraordinary experience,” said Lange.
Lange is available to comment on the mission Monday May 26.
The concept of the Telltale was created at the U of A and the instrument was constructed in Denmark. The device is a small piece of the Phoenix Mars Lander spacecraft that will be landing on Mars on Sunday, May 25. The lander, a joint mission between NASA, the University of Arizona and the Canadian Space Agency, launched from Florida on August 4, 2007.
Once the craft lands, Lange says they must first spend time seeing how well the instruments survived the landing. Lange leaves in June for Arizona, where he will be spending part of the summer at the Science Operation Centre doing research and analysis.

For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.
To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...
For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.

Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.
A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...
