History Flashback: Space shuttle mission STS-51A
When Discovery blasted off on November 8, 1984 it marked the start of arguably the most daring and complex space shuttle mission. The astronauts successfully launched two communications satellites and then recovered two others during extraordinary spacewalks using jet-propelled backpacks and muscle power. Over the next few days we'll present video clips of the mission for our Spaceflight Now Plus subscribers. Today, we offer launch day coverage:

Disk resembling asteroid belt found around star
When unusually warm dust was first discovered around a nearby star, called zeta Leporis, infrared astronomers begun hunting in detail for the heat source. According to the latest research at UCLA, what the star may be undergoing is asteroid and planet formation similar to that of our own early solar system.

Odyssey continues moving closer to mapping orbit
Flight controllers of NASA's 2001 Mars Odyssey mission report that the aerobraking phase is proceeding right on schedule and should be completed in early January. During the aerobraking phase of the mission, the spacecraft is controlled so it skims the upper reaches of the martian atmosphere on each orbit, to reduce the vehicle's speed.
