So around 2 pm EDT space shuttle Atlantis will launch for the last time to the Hubble Telescope. The risk is that Hubble is about 350 miles up, the space station is 200, so in the event of a problem there is no way to get to the station. Endeavour is waiting on the pad for a rescue mission in the event of a problem.
Hubble will get a new camera with a higher res that will make it 70% more powerful then its launch. New batteries and new gyroscopes that will allow it to operate until 2014.
