NASA has tacked on an additional day to the final mission of the space shuttle Discovery, giving crews more time to work on the International Space Station. The extension, the second one-day addition granted by shuttle managers this week, means that the shuttle will undock from the station on Monday and land at the Kennedy Space Center mid-day Wednesday. The additional time will allow the STS-133 crew to unpack the Leonardo cargo module installed on the station earlier this week as well pack trash into the Japanese HTV-2 cargo spacecraft that will undock from the station later this month. Thursday was largely an off-day for the STS-133 crew, which performed a series of media interviews and also talked with President Obama.
