Look at stars!

Astronauts from the Atlantis on Thursday gifted the Hubble Space Telescope with a deeper insight into the universe in the form of a new farsightedness-special camera eye during the arduous spacewalks to fix the renowned observatory. It gives Hubble the power of looking substantially further into the horizontals and verticals of the universe than earlier models.

“We gave Hubble a hug, and in traditional Hubble fashion it threw us a few curves” said Grunsfeld, who led the spacewalk and along with his partner Andrew Feustel fixed the telescope in a more than seven hour outside expedition.

Replacing Hubble’s old imager with a $132 million “Wide Field Camera 3” will offer it the power of probing deeper into the evolution of universe and revealing the unsolved mysteries of dark energy and matter. The universe being 13.7 billion years old, it is designed to look back 500 million years post birth of the universe. They also fixed a key computer controller unit that beams images to Earth, sending information about our planet.

Astronauts John Grunsfeld and Andrew Feustel installed wide field camera and data router on the Hubble Space Telescope. The 7 hour, 20 minute expedition took almost an hour longer than scheduled.

The other items of Space Agenda:

The spacecraft Atlantis was launched on Monday on an 11-day shuttle mission to renovate the telescope and extend its life till 2014. Wide field camera installment was among a total of five outside applications in the “Hubble” which was anchored with the claw of the shuttle on Wednesday.

For Friday the substitution of several batteries and gyroscopes is aforethought. The gyroscope measures the attitude when Hubble is changing its pointing from one target (a cosmic body) to another, helping to control the telescope’s pointing while scientists are observing those targets.

While the third space walk on Saturday is about the installment of “Cosmic origins Spectograph”. This will allow hubble to have unique looks at weakly radiating cosmic objects in the range of the ultraviolet (UV) to visible radiations.

The most necessitating task is the repair and equipping of “Space Telescope Imaging Spectrographs” which is scheduled during the seventh day which is no more functioning since 2004. Besides, the astronauts also have to attach about 100 small screws. In addition, they should back the isolating “steel covers” which will protect the very sensitive parts of Hubble against the huge temperature variations, which is normal in space.
