The Hubble Space Telescope was repaired and enhanced during the STS-125 mission of Space Shuttle Atlantis. Launched on May 11, 2009, the 11 day mission included some five spacewalks to make repairs and upgrades to the telescope, leaving it more capable and hopefully prepared to last another five years.

Seven astronauts blasted off on the space shuttle Atlantis on Monday for one last flight to the Hubble Space Telescope — an extraordinarily ambitious mission that NASA hopes will lift the celebrated observatory to new scientific heights.
The six men and one woman who will attempt the complicated, riskier-than-usual job shouted, waved and raised their fists as they headed out to the pad, eager to get going after waiting seven months to fly. Their flight was delayed last fall, two weeks before the scheduled launch, after the orbiting telescope broke down.
The 19-year-old Hubble, last visited by astronauts seven years ago, is way overdue for a tuneup.
In this fifth and final repair mission, two spacewalking teams will replace Hubble's batteries and gyroscopes, install two new cameras and take a crack at fixing two broken science instruments, something never before attempted. Those instruments, loaded with bolts and fasteners, were not designed to be tinkered with in space.

The right tools can make any job easier, and that will be especially true this week when the Hubble Space Telescope gets its last tuneup.
When space shuttle Atlantis blasts off Monday on the final flight to Hubble, the astronauts will be carrying 180 special tools, and 116 of them were designed just for this mission, which involves tricky repairs to two science instruments that were never intended to be fixed in space. Liftoff is scheduled for 2:01 p.m. EDT.
The Hubble Space Telescope was launched in 1990. It has been serviced four times before, with the last servicing mission occurring in 2002.
"Over the last few years, we've seen significant deterioration within the set of scientific instruments that we provide to the astronomical community," says David Leckrone, senior project scientist for Hubble at NASA.
He says that after this visit, if all goes well, Hubble should be more powerful than ever before.
Astronauts are scheduled to go on five spacewalks to give the telescope an upgrade that includes new batteries and gyroscopes, and additional science instruments.
But some of the most ambitious repair work involves "actually going into the very guts of instruments that have suffered failures that were never meant to be touched on orbit," says Michael Weiss, deputy program manager for Hubble at NASA's Goddard Space Flight Center in Greenbelt, Md.The right tools can make any job easier, and that will be especially true this week... more

Peering more than 100 million light-years across the universe, the Hubble Space Telescope caught three galaxies interacting, which is an astronomer's euphemism for a gravitational struggle of colossal proportions. The three galaxies—NGC 7173 (left), NGC 7174 (center right) and NGC 7176 (lower right)—are locked in a battle for supremacy that may result in NGC 7174 being torn to shreds. The three galaxies may also someday merge into a single massive entity.Peering more than 100 million light-years across the universe, the Hubble Space... more

This new Hubble photo reveals a strange galaxy in a far off cluster of galaxies called the Coma cluster.
The galaxy, NGC 4921, is unusual because of its light, wispy swirls. These aren't as distinguished and bright as the spiral arms in most spiral galaxies, which are powered by the active creation of new stars. This weak-limbed galaxy belongs to a class called "anemic spirals," named for their wimpy arms and weak star formation.This new Hubble photo reveals a strange galaxy in a far off cluster of galaxies called... more

The University of Leicester has launched a new course which will teach students the basics of living and working in space. Staff at the university have employed former Nasa astronaut Jeff Hoffman to teach the course.
Students will gain lessons on how to survive in space, cope with the psychological demands of long-term space travel, and how to conduct a spacewalk.
Hoffman took part in spacewalks to fix cameras on the Hubble Space Telescope. He will teach at Leicester as a visiting professor.The University of Leicester has launched a new course which will teach students the... more

A violent merger between two galaxy clusters appears to have split ordinary matter from dark matter.
NASA's Hubble Space Telescope and Chandra X-ray Observatory show dark matter from each cluster appearing to pass through the cosmic mess unscathed, leaving ordinary matter behind in the galactic pileup.
Nobody knows what dark matter is, and it has never been directly detected. Its mysterious presence is known by observations of how it affects regular matter or light, which can be bent by gravity. Astronomers say dark matter makes up as much as 90 percent of all matter in the universe.
Hubble helped map out the distribution of dark matter in the collision by seeing the bending of light around areas with dark matter. Chandra spotted X-rays from the hot gas that makes up the bulk of ordinary matter in the clusters.
The latest observations of the MCSJ0025 cluster appear to to back up earlier findings from another cosmic collision in what's called the Bullet Cluster. That impact also tore normal and dark matter apart and demonstrated the forcible separation of ordinary and dark matter.
The same separation suggests that dark-matter particles interact only weakly outside of gravity's influence, given that they passed by one another inside the collision zone with little visible effect.
The research team also estimated the mass distribution of both dark and ordinary matter by using Hubble's visible-light images. Each cluster boasted almost a quadrillion times the mass of the sun.
Results from the new study of collision, a scene that's about 5.7 billion light-years away and involved speeds of millions of miles per hour, are detailed in an upcoming issue of The Astrophysical Journal.A violent merger between two galaxy clusters appears to have split ordinary matter... more
