Most Space missions start with spectacular launches and end with successful albeit dangerous Space Walks. While Shuttle Endeavor's mission started off exactly as expected, it has already encountered a couple of unusual twists and the mission is nowhere close to the end.

Shuttle Endeavor and its crew of five, left for Space from the Kennedy Space Center in Florida on Friday, November 15th, in a rare but spectacular evening launch.

The shuttle's mission is to add more living space to the International Space Station, so that six astronauts can stay there for extended periods at any given time, and also to repair one of its damaged solar wings and restore full power to the Station.

It was during an attempt to fix the solar panels when the first incident occured. Lead spacewalker Heide Stefanyshyn-Piper was busy repairing the panel when one of the grease guns she was using leaked on her glove. While trying to clean up the mess, she accidentally let go of the tool bag. She tried to retrieve it, but to her dismay, the bag with tools which cost about $100,000USD simply drifted away into space (see pic above).

Luckily, the scientists have an extra tool bag, which Heide will now share with another astronaut to complete the repairs. As for floating tools - scientists believe they will burn out near the Earth's atmosphere and disappear.

If that wasn't excitement enough, yesterday the astronauts revealed that one of the two spiders that they took to Space had gone missing. The two had been carried to Space to observe how they weave webs and feed in zero gravity. While nobody is sure where it is, scientists are guessing that it may have sneaked into the other spider's cage.

However, they can't confirm that since the other spider has weaved a heavy tangle of web all around his cage, making it impossible to peek inside. Their only hope is that the errant spider will show up soon.

While yesterday's second spacewalk went without any incident - there are still two more planned before the mission ends and anything could happen between now and then - Stay tuned for further Adventures in Space!
