Space shuttle Discovery is on its way to the International Space Station. Discovery and seven astronauts blasted off shortly before sunrise Monday. They're delivering supplies and experiments to keep the station running long after the shuttles retire later this year, according to a report of the Associated Press. Three women are riding aboard Discovery. A fourth is already at the space station. She arrived Sunday, courtesy of the Russians. That sets a record for the most women flying on spacecraft at the same time. This was NASA's last scheduled shuttle launch in darkness. Only three missions remain after this one.
