    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.

New Horizons Trajectory Animation

This animation illustrates the trajectory (path through the Solar System) of the New Horizons space mission to Pluto and beyond.

Note: If you cannot see the movie you may need to download the latest QuickTime player.

Movie courtesy of NASA/Johns Hopkins University Applied Physics Laboratory/Southwest Research Institute.

The animation begins with the launch of New Horizons from Earth on January 19, 2006. New Horizons zoomed away from our planet at the highest speed of any spacecraft leaving Earth so far... it was traveling at 16.21 km/s (36,300 mph) when its engine shut down!

New Horizons crossed the orbit of Mars on April 7, 2006. The spacecraft safely passed through the asteroid belt between the orbits of Mars and Jupiter during a five month period lasting from May through October 2006.

Next, the animation shows the spacecraft during its Jupiter flyby in February 2007. A gravity assist from the gas giant planet increases New Horizon's speed, cutting years off its journey to Pluto.

The spacecraft is expected to fly past Pluto and its largest moon Charon in July 2015. After that, scientists hope to steer New Horizons on to a close encounter with one or more Kuiper Belt Objects.
