    Atmospheric CO2 Level Tops 400 ppm

    During the week of May 13th, the CO2 level at the Mauna Loa Observatory in Hawaii topped 400 ppm repeatedly. Daily levels of CO2 can vary due to weather, and there are seasonal trends as well. The level of atmospheric greenhouse gases continues to increase, now over 120 ppm since the Industrial Revolution began. For more on the Keeling Curve, see http://keelingcurve.ucsd.edu/.

    Massive Tornado Outbreak on Tornado Alley

    The week of May 19 brings dozens of tornadoes to Tornado Alley in the states of Oklahoma, Kansas, Iowa, Illinois and Missouri. On May 20th, a massive tornado struck Moore, Oklahoma, devastating communities - destroying over 100 homes and hitting two elementary schools and a hospital - with many casualties and deaths. Our thoughts are with our friends and colleagues suffering from these storms. For more on the May 20th storms, see the NOAA Storm Prediction Center Storm Report.

    Kansas Legislator Proposes Bill to Outlaw Sustainability Education

    A bill has been introduced in the Kansas legislature this week that would prohibit the promotion of sustainability. Here is a link to the one-page bill: http://www.kslegislature.org/li/b2013_14/measures/documents/hb2366_00_0000.pdf. See report on Bloomberg News.

Mars Reconnaissance Orbiter

Mars Reconnaissance Orbiter (MRO) is a robot spacecraft that is orbiting Mars. It will study Mars from November 2006 to November 2008. It will take lots of pictures and gather lots of data about Mars.

MRO is a big spacecraft. It is bigger than other Mars orbiters that went to Mars before MRO. MRO also has the most powerful camera that has ever flown on mission to another planet. That camera is called HiRISE (High Resolution Imaging Science Experiment). Cameras on earlier Mars orbiters could spot objects on Mars the size of a dinner table. HiRISE will zoom in to spot objects on Mars as small as a dinner plate.

MRO has two other cameras. One of those cameras, plus an instrument called a radiometer, will study the atmosphere of Mars. MRO carries another instrument called a spectrometer. The spectrometer will make a map of the minerals on the surface of Mars. MRO also has radar that will search for ice underground on Mars.

MRO will make better maps of Mars. It will help scientists decide where future missions to Mars should go. It might even help us decide where the first people who go to Mars should land!
