The fifth and final trip by shuttle astronauts to the Hubble Space Telescope will leave the historic satellite more capable than it has ever been, senior NASA officials said this week.
A shuttle mission scheduled for mid-October is set to deliver new components and undertake extensive in-space repairs a first on broken instruments attached to the orbiting observatory.

It is the only known gamma-ray burst to have had a visible component bright enough to see with the naked eye.
This was the brightest optical and infrared event that mankind has ever recorded, said Joshua Bloom, an assistant professor of astronomy at the University of California, Berkeley, and first author of an analysis of the event submitted to The Astrophysical Journal (ApJ) less than a week after the burst and accepted this week. When more of these events are detected, we will open up the possibility of studying the infant universe with this new tool.
The gamma-ray burst was first detected by NASA's Swift satellite on March 19, after which many Earth- and space-based telescopes slewed into position to observe the rapidly fading light. Situated within the constellation Bootes, its flash eventually was pinpointed at a distance of about 7.5 billion light years.
Bloom's group, using a robotic telescope in Arizona, began observing the intense infrared light just 54 seconds after the event began. The telescope, called the Peters Automated Infrared Imaging Telescope (PAIRITEL), was operating autonomously on a direct link from the Swift satellite. Bloom's graduate students Daniel Perley and Adam A. Miller analyzed the data.
This was the most powerful event ever seen in human existence, enthused Bloom's coauthor Alex Filippenko, UC Berkeley professor of astronomy
