    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.

News story originally written on February 11, 1998

Thanks to a recent Earth swing-by, the NEAR spacecraft is on its final approach. NEAR stands for Near Earth Asteroid Rendezvous. This is the spacecraft that flew by asteroid Mathilde in June 1997, past Earth in January 1998 and is now on its way to asteroid Eros, the final mission target!

NEAR is scheduled to arrive at Eros in December 1998. It will orbit the asteroid at an altitude of 600 miles. The spacecraft will descend to 200 miles altitude by February and will continue to lessen its altitude during a year long study of the 25 mile long asteroid. Scientists hope to map the surface of the asteroid as well as determine its composition and chemical characteristics. On February 6, 2000, the mission will come to its climax as the NEAR spacecraft decends onto the asteroid (hopefully in a controlled fashion!).

This is an unique and exciting mission - stay tuned for more details!
