Revolving around space!

Here is a view of space brought to you from Book club. These are a few images captured by Hubble Camera! The log states some of the parts on Hubble are almost welded after being in service. For their first spacewalk of the STS-125 mission, Massimino and Good will spend the bulk of their time replacing the Hubble Space Telescope’s three rate sensing units with a detailed illustrated map for you below. Each unit is part of a rate gyro assembly, which senses vehicle motion and provides rate data to help point the telescope precisely for its science observations.

After the new rate sensor units are installed, Massimino and Good are scheduled to perform the first half of the mission’s battery replacement work. They will be working in the telescope’s Bay 2 to replace the first of two battery modules. Each module weighs 460 pounds and contains three batteries, providing electrical power to support Hubble operations during the night portion of its orbit. The second battery module will be installed during the fifth and final spacewalk the the wfpc2 with the wide field camera proved to be a challenge. only when the seven astronauts reach earth will the true difficulty be known remembering that they have to work in zero gravity which makes space suit ripping or any material a very probable likelihood!

The task of updating and repairing Hubble is to be carried out by Astronaut John Grunsfeld and he likens the intricacy of the tasks he and his colleagues will perform to "performing brain surgery in space" They will face major hurdles, such as unscrewing dozens of minute screws, as the design didn't incorporate such, he will have to do this while wearing gloves five layers thick and removing razor-sharp circuit boards capable of piercing the $10 million spacesuits. with these the only barrier that keep them alive in the vacuum of space!"I would consider this the climbing Mount Everest of spacewalking missions," said Mr Grunsfeld, 51.'The big unknowns are where we’re pushing the envelope further than its been done before in spaceflight. we’re trying some techniques that haven’t been done before.

"In training it’s been going very well…the only hesitation I have is that Hubble has a way of surprising us. There have been previous servicing missions to the Hubble, but this will be the last – and the most risky.'You could say "Oh it’s going to be a piece of cake, we’ve done this five times" - except on this mission we are going to be repairing instruments that were never designed to be repaired in orbit,' explained Ed Weiler, NASA’s associate administrator for science missions. He added: 'This is really going to be tough, the toughest servicing mission we have ever attempted."NASA promises that, if successful, Atlantis’s mission will allow Hubble to once more 'push the boundaries of how deep in space and how far back in time humanity can see.'Cdr Altman said: 'It’s going to be a busy time, it is challenging - and it’s going to be amazing.'

With no competition NASA certainly has the monopoly to deploying any amount of cargo into space at the ready and almost at any time. But the space shuttle is nearing it life cycle at almost nearly thirty years. Here is a picture of what Atlantis hopes to do with this "historic mission". As down here on earth people are hoping to twitter taking it all for granted you can even post a message to the shuttle crew. As their are so many variables, these seven astronauts are taking a terrible gamble as they clamber around space.
