The space shuttle Endeavour was hauled to launch pad 39B at the Kennedy Space Center early Friday for work to prepare the ship for a flight NASA managers hope will never happen: a mission to rescue the astronauts charged with repairing and upgrading the Hubble Space Telescope.

The shuttle Atlantis is scheduled for launch May 12 from pad 39A on NASA's fifth and final mission to the space telescope. Because Hubble operates in a different orbit, the Atlantis astronauts would not be able to seek safe haven aboard the International Space Station if any problems develop that might prevent … Read more

Even factoring in a recent satellite collision, a threat analysis found that the crew of space shuttle Atlantis will not face a dramatically higher risk of catastrophic damage due to space debris when it travels to the Hubble Space Telescope in May, according to NASA.

The overall risk of impact damage is higher for a mission to Hubble, which is 350 miles from Earth, than it is for a flight to the International Space Station, which orbits at a lower, less debris-choked altitude. However, the actual numbers are better than flight planners initially expected, a NASA official said Thursday.

The space shuttle Endeavour, the designated rescue ship for next month's Hubble Space Telescope servicing mission in case something goes awry, was hauled from its processing hangar to the vehicle assembly building at the Kennedy Space Center in Orlando, Fla., early Friday.

Inside the vehicle assembly building, the shuttle will be attached to an external tank and solid-fuel boosters. Rollout to pad 39B is planned for April 17.

The shuttle Atlantis already is mounted atop pad 39A for work to ready the ship for blastoff on May 12, at 10:31 a.m. PDT, on a fifth and final … Read more

The space shuttle Atlantis, bolted to a mobile launch platform atop an Apollo-era crawler-transporter, was hauled to launch pad 39A at the Kennedy Space Center on Tuesday for work to ready the ship for blastoff May 12 on a fifth and final mission to service the Hubble Space Telescope.

Originally scheduled for launch on October 14, the long-awaited Hubble overhaul was delayed when one channel of a critical data-processing system unit aboard the telescope failed just two weeks before liftoff. NASA managers decided to replace Hubble's entire science instrument command and data handling unit, or SI/C&DH, to restore redundancy and improve reliability.

But testing a spare ground unit at the Goddard Space Flight Center in Greenbelt, Md., getting it certified for flight, and working the mission back into NASA's shuttle manifest ended up delaying Atlantis and Hubble Servicing Mission 4, or SM-4, for seven months, when all was said and done.

The replacement SI/C&DH was delivered to the Kennedy Space Center on Monday, and Atlantis, attached to an external fuel tank and two solid-fuel boosters, took its first step toward space with a six-and-a-half-hour, 3.2-mile trip from the Vehicle Assembly Building to pad 39A on Tuesday.

Shuttle commander Scott Altman, pilot Gregory C. Johnson, flight engineer Megan McArthur, and spacewalkers John Grunsfeld, Michael Massimino, Andrew Feustel, and Michael Good plan to fly to Kennedy late this week to inspect the replacement computer unit before it is moved to the pad April 18, along with the rest of the Hubble payload, for installation in Atlantis' cargo bay.… Read more

If you think the new Google Earth update that shows even more about Mars' surface is cool, Microsoft thinks what's it's about to offer is even cooler.

The company, together with NASA, announced on Tuesday plans to make planetary images and data available via the Internet. The two organizations will jointly develop the technology and infrastructure necessary to make NASA content--including high-resolution scientific images and data from Mars and the moon--explorable on Microsoft's online virtual telescope for exploring the universe, called WorldWide Telescope.

The WorldWide Telescope is a Web 2.0 visualization environment that functions as a … Read more

Last year, Microsoft introduced its answer to Google Earth's Sky mode, Stellarium, and other celestial mapping programs with WorldWide Telescope, and it's now making it available via any browser that's been bolstered by Silverlight. The basic features of the downloadable program have been ported to the Web, though some of the higher-end renderings didn't make the cut.

As in the desktop version, users can whip around the galaxy using their mouse's scroll wheel to zoom in and out, and hold down the left mouse button to drag the sky from one position to another.

HAT CREEK, CALIF.--From the perspective of an extraterrestrial, I wonder if there would be much difference between a human and a deer.

You might think that's an odd question, but on Wednesday, as I stood in an open plain here, at around 5,000 feet, with Mount Shasta visible far off to the north, a stunning blue sky, I watched a deer poking around at the base of what on its own would be an odd piece of astronomy equipment.

In fact, though, the 20-foot-diameter antenna the deer was investigating was just one of 42 identical units that … Read more

Microsoft's Worldwide Telescope has a new celebrity tour guide: Wall-E.

One of the features of the telescope software is the ability for both experts and amateur stargazers to offer their own guided tour of the universe to share with others. The latest such tour is by Wall-E, the animated robot from the Disney/Pixar movie of the same name.

"WorldWide Telescope is about making science fun for everyone," Curtis Wong, manager of Microsoft's Next Media Research Group, said in a statement. "By working with Disney/Pixar, we're enabling kids and families to discover the … Read more

SAN FRANCISCO--If you're one of the many people who doubt there's intelligent life anywhere else in the universe, or even someone who thinks there is but that it will take centuries to find it, get ready to be surprised.

"We'll find E.T. within two dozen years," senior SETI astronomer Seth Shostak said Tuesday night at an event held at Yahoo's Brickhouse here.

That is, he said, if the assumptions of many researchers within the SETI Institute are correct, assumptions that are based on a collision of computing power under Moore's Law and … Read more
