ASTRONAUTS COMPLETE SECOND SPACEWALK
Astronauts Mike Gernhardt and Jim Reilly spent six and half hours in space Tuesday night, as they added supply tanks to the new airlock they installed on the International Space Station over the weekend. The spacewalk went very smoothly, despite come computer glitches at the beginning, and the had enough time to install an extra tank. The crews of both the station and the shuttle will have another day to prepare for the third and final spacewalk on Friday night. Atlantis is expected to return back to Earth on July 24.

JUPITER'S CLOUDS PUZZLE ASTRONOMERS
NASA technicians have assembled a kaleidoscopic movie from 1,200 images taken by the Cassini spacecraft as it flew by Jupiter earlier this year. This movie shows that storms in the polar regions are just as stable as those around the equator. This is different from what the Astronomers were expecting, as photos of Jupiter generally show the poles to be a much more mottled in appearance.
SOLAR SAIL IS READY TO FLY
Despite setbacks earlier this year, the Planetary Society is nearly ready to launch an unmanned solar sail on board a converted intercontinental ballistic missile from a Russian nuclear submarine. The 30-second suborbital flight will test how the lightweight sail sections unfurl in the sunlight, and will pave the way for future tests later this year. The launch is scheduled for Thursday from the port at Severomorsk.
