Science in the News this Weekend
First, Mt. Redoubt continued to erupt several times on Saturday, March 28, sending volcanic ash to Anchorage, 100 miles to the northeast. The ash plume was 45,000 to 50,000 feet high on Saturday. After the first eruption, there was also strong seismic activity. The Ted Stevens Anchorage International Airport shut down due to the ash, but reopened on Sunday and is expected to be fully operational on Tuesday. On Sunday, Mt. Redoubt did not erupt, but it did have low-level tremors. For more information, see the Associated Press article here.
Second, the Space Shuttle Discovery landed in Florida on Saturday, ending its 13 day mission to the International Space Station (ISS). Discovery brought Dr. Sandra Magnus back to Earth after four months in space at the International Space Station. She was replaced aboard the ISS by Koichi Wakata, a Japanese astronaut, who arrived via Discovery. Additionally, a Russian Soyuz capsule with an American tourist on board has docked safely at the International Space Station just a few days after Discovery’s departure.
