NASA Scrubs Attempted Launch of Shuttle Atlantis
8 September 2006 10:56 a.m. EDT
CAPE CANAVERAL, Fla. – For the second time in three days, NASA has scrubbed the attempted launch of its space shuttle Atlantis, this time due to an errant fuel tank sensor reading inside the orbiter’s 15-story fuel tank.
The decision comes after a series of discussions and debates over one of four engine cutoff sensors inside the liquid hydrogen portion of Atlantis’ external tank. The sensor failed a standard prelaunch check.
NASA is providing live coverage of Atlantis’ launch. You are invited to follow the briefing using SPACE.com’s NASA TV, which is available by clicking here or using the button at the left.
