Space shuttle Endeavour sits atop launch pad 39A after arriving from the Vehicle Assembly Building to prepare for Mission STS-134 at the Kennedy Space Center in Cape Canaveral, Florida, Florida March 11, 2011.
Reuters  Astronaut Mark Kelly says doctors have cleared his wife, Arizona Congresswoman Gabrielle Giffords, now recovering from a gunshot wound to the head, as healthy enough to attend his space shuttle launch on Friday.
Word that Giffords had been given a medical approval to make the trip to Cape Canaveral, Florida, for the blastoff, which President Barack Obama also plans to attend, came in CBS Evening News interview slated to be broadcast on Monday.
The network released excerpts from Katie Couric's interview with Kelly on Sunday.
"Yes, I've met with her doctors, her neurosurgeon and her doctors. And ... they've given us permission to take her down to the launch," Kelly said.
Asked Giffords' reaction to hearing that she's been given the green light to attend the launch, Kelly said, "I think she said, 'awesome,' and she pumped her fist."
James Campbell, a spokesman for the Houston hospital where she is undergoing rehabilitation, told Reuters in an e-mail on Sunday the hospital plans to issue a statement about her plans to travel on Monday.
The event would mark the first extended outing the Arizona Democrat has made from a hospital environment since she was gunned down as she met with a group of constituents outside a Tucson, Arizona supermarket on January 8.
Six people were killed and 13 others were wounded, Giffords among them, when a gunman opened fire on the congresswoman and bystanders. Jared Loughner, 22, a college dropout with a history of erratic behavior, is charged with the shooting.
Kelly, the commander of NASA's next-to-last scheduled shuttle mission, took a leave of absence after Giffords was wounded but returned to work in February after she was transferred to the Houston rehabilitation center.
The Endeavour mission led by Kelly will be delivering equipment to the International Space Station. NASA plans to fly one last mission with sister ship Atlantis in June before ending the 30-year-old shuttle program.
Kelly told Couric that the injury to the left side of his wife's brain has made it difficult for her to regain her ability to walk to and to speak but left the right hemisphere, which controls personality and cognitive functions, intact.
"Her personality's a hundred percent there," he told Couric.
The Arizona Republic reported on Sunday that Giffords still struggles to piece together lengthy sentences but can articulate brief phrases such as "love you" and "I miss Tucson."
The newspaper said she is working to improve the use of her right arm and leg through therapy that involves pushing a grocery cart, bowling and indoor golf.

Rose Galaxies captured by Hubble telescope


Friday 22 April 2011
NASA's Hubble space telescope celebrates its 21st birthday with the release of the stunning image of two galaxies linked by a bridge of stars, creating a "rose" of galaxies



The image shows a large spiral galaxy apparently attached to another one by a swirl of stars – a rose-like effect caused by the gravitational pull of the galaxy below it.

The sprinkling of blue jewel-like points across the top of the larger galaxy is the combined light from clusters of intensely bright and hot young blue stars. These massive stars glow fiercely in ultraviolet light.
The two galaxies, known as ARP 273, are in the Andromeda constellation 300m light years from Earth.
The picture, which was captured in December last year, shows a bridge of material between the two galaxies that are separated from each other by tens of thousands of light-years.
The image was released by NASA to celebrate the 21st anniversary of the Hubble space telescope's deployment into space.

Hubble was launched in April 1990 aboard Discovery's STS-31 mission, and has since revolutionised current astronomical research from planetary science to cosmology.
In its 21-year lifetime the telescope has made more than 115,000 trips around Earth, flying nearly 3 billion miles in total – which is roughly Neptune's average distance from the Sun.
sing Hubble's data, astronomers have published almost 10,000 scientific papers, making it one of the most productive scientific instruments ever built.
A series of heroic missions by astronauts have been made to service Hubble, helping to make it the longest-operating space observatory.

Senator Barbara Mikulski of Maryland said. "Its jaw-dropping images have rewritten the textbooks and inspired generations of schoolchildren to study math and science. It has been documenting the history of our universe for 21 years."
