    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 Mission Movie

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

This animation illustrates 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.

This animation begins shortly after the launch of New Horizons on January 19, 2006. It opens with the spacecraft separating from the upper stage (a Boeing STAR-48B third-stage kick motor) of its launch vehicle just above Earth's atmosphere. 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!

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 animation then shows a reddish Pluto appearing reflected in the lens of the spacecraft's camera, and the swath of the camera's field of view as it sweeps across Pluto. New Horizons pivots to keep Pluto in the field of view of its cameras as is swings past that icy world. As the spacecraft's motion plunges it into Pluto's shadow, New Horizons studies Pluto's thin atmosphere by observing changes in the sunlight passing through it near the edge of Pluto's disc. Just minutes after its encounter with Pluto, New Horizons zips by Pluto's large moon Charon. Finally, some time after the Pluto flyby, the spacecraft passes one of the many Kuiper Belt Objects and studies that frozen time capsule of our Solar System's formation.
