航天：“奮進(jìn)號(hào)”航天飛機(jī)成功發(fā)射
The second time was the charm for NASA as the space shuttle Endeavour took off early Monday morning. It was supposed to launch on Sunday, but as we told you about yesterday, that plan was delayed because of weather. The shuttle and its crew are on a two-week mission to the international space station. When they get there, they’ll deliver some new components to the station, and they’ll do a few spacewalks. The mission is scheduled to last two weeks, all together. This is actually one of the last missions for the space program. It’s scheduled to end in 2011. And with just four more flights to go, Endeavour’s 4 a.m. departure might have been the shuttle program’s last night launch.
