    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.

Dan Brandenstein

Dan Brandenstein is an American astronaut who was born on January 17, 1943 in Wisconsin. Before he became an astronaut, Brandenstein served as a Navy pilot in the Vietnam War. He has flown over 5600 hours in 24 different types of aircraft.

Brandenstein became an astronaut in 1979. He has made four spaceflights spending over 576 hours in space.

In 1983, Brandenstein piloted the first nighttime launch and landing of a space shuttle. In 1985, he commanded an international mission. The crew included Saudi Prince Sultan al-Saud and French Patrick Baudry.

In 1990, Brandenstein commanded shuttle Columbia in a mission that set a shuttle endurance record. The crew spent 10 days in space and retrieved the Long Duration Exposure Facility.

During his last mission in 1992, Brandenstein and his crew performed one of the most difficult space shuttle missions to date. Brandenstein and pilot Kevin Chilton performed some risky flying aboard the new Endeavour shuttle in an attempt to retrieve a satellite. They flew within a few feet of the rotating satellite, allowing the rest of the crew to literally grab it and pull it into the shuttle.
