    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.

Cassini arrives at Saturn
News story originally written on June 30, 2004

A spacecraft named Cassini will get to Saturn on June 30, 2004. Cassini's rocket engine will burn for 96 minutes to slow the robot spaceship down. If it works, Cassini will be captured into orbit around Saturn. Cassini was launched in 1997, so it has taken nearly seven years to complete its long journey to Saturn.

Cassini will orbit Saturn for at least four years. It will use its 12 instruments to study Saturn, its rings, and its moons. Cassini is also carrying a smaller probe named Huygens. Huygens will land on Titan, Saturn's largest moon, in January 2005.

Cassini will get its closest views of its entire mission of Saturn and of Saturn's rings during this first swing by the planet. In fact, Cassini will pass through the rings twice while braking into orbit. Cassini will turn its main antenna dish forward when it passes through the ring, to act as a shield against high-speed collisions with ring particles.
