    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.

CONTOUR Lost in Space
News story originally written on August 27, 2002

We are sad to report that the Comet Nucleus Tour (CONTOUR) is currently lost in space. The CONTOUR spacecraft was launched July 3, 2002 to explore the nucleus of comets. It was scheduled to fly by at least two comets over the next few years, taking pictures and collecting dust from the nucleus of each.

Controllers lost contact with CONTOUR on Aug. 15, when its rocket ignited 140 miles above the Earth to boost the spacecraft out of Earth's orbit. Controllers expected to regain contact within an hour, but there has been no contact with CONTOUR since the rockets ignited.

By searching the skies with the telescope in Kitt Peak, Arizona, scientists found three objects in the location where CONTOUR should be. Since CONTOUR was originally in one piece, these pictures may indicate that it has broken apart.

Mission controllers may have lost CONTOUR but they have not lost hope! There is a possibility that the main part of the spacecraft is still intact if only non-essential parts fell off. They will continue listening for signals from the spacecraft until early December, when CONTOUR will be in a better location to receive a signal from Earth.
