Next month’s shuttle flight to the Hubble Space Telescope faces an increased risk of getting hit by space junk because it will be in a higher, more littered orbit than usual, NASA said Monday.

New number-crunching puts the odds of a catastrophic strike by orbital debris including bits of space junk at about 1-in-185 during Atlantis’ upcoming mission to Hubble. That compares to 1-in-300 odds for a shuttle flight to the International Space Station, shuttle program director John Shannon said Monday.

Orbital debris is the newest, biggest threat to an orbiting space shuttle, surpassing even the liftoff dangers of the main engines and booster rockets, and the always-dangerous re-entry, Shannon said.
