Mars Phoenix Probe Successfully Launched

necro81 writes "The Mars Phoenix lander, built from the ashes of two earlier Mars missions, successfully launched atop a Delta II rocket from Canaveral this morning. The mission takes the 350-kg lander to northern latitudes (comparable to Greenland or Siberia) to investigate subsurface ice for the chemical precursors of life. The lander should arrive on Mars on May 25, 2008. 'NASA has never attempted to land a spacecraft on Mars at such a high northern latitude. A lander intended for the red planet's South Pole went silent immediately upon arrival in 1999. That failure, combined with the loss of the companion Mars orbiter, prompted NASA to cancel a 2001 lander mission. The parts from that scrapped mission were used for Phoenix, thus its name, which alludes to the mythological bird that rises from its own ashes.'"

      The Canadian contribution to the mission is a meteorological station that includes a pressure sensor, three temperature sensors on a mast, a wind telltale, and a lidar (laser radar) system. The lidar will be used to obtain profiles of dust in the atmosphere, and uses a technique very similar to radar or sonar but using pulses of laser light instead.

The Can con will be complemented by other instruments for atmospheric measurements, including the Stereoscopic Surface Imager (SSI) which will take pictures of the sky through a variety of filters, and the MECA which will measure water vapour. You can read more about the Phoenix instruments at http://phoenix.lpl.arizona.edu/science05.php. This programme, as all space programmes are, is massively collaborative. It is a partnership between NASA, the Canadian Space Agency (CSA), and other international contributors. Peter Smith from the University of Arizona is the Science Team lead. On the Canadian side the Science Team is composed of researchers from York University, Dalhousie University, University of Alberta, and the Geological Survey of Canada. The meteorological station was built by MDA (who also built the Canadarm), Optech and Passat. The launch this morning was quite a thrill.

      What it does is deflect the solar wind from hitting our atmosphere and blasting our atmosphere away like a firehose. The reason it can do anything to solar wind is that the solar wind is electrically charged. Anything with an electrical charge gets pushed or pulled by magnetic fields, neutral particles like the atoms of gas in our atmosphere are not affected.

      So, if you set up a wicked strong magnetic field near a crater, and then released gas in the crater, the gas would react the same was as if there was no field... it would whoosh out into the rest of the martian atmosphere and be lost. The martian atmosphere would of course be just a teeny bit thicker, but not so much that you could notice, or probably even measure.
