Pluto Mission To Launch Wednesday Afternoon Following High Wind Abort

NASA controllers scrubbed the New Horizons mission to the outer solar system due to persistent hazardous ground winds at the launch site at Cape Canaveral Air Force Station, Fla. The next launch attempt will begin Wednesday, Jan. 18 at 1:16 p.m. Eastern Time.

Controllers postponed the launch of the probe to Pluto and beyond seven times due to wind gusts exceeding 33 knots, the maximum safe velocity for launch of the Atlas V booster and its payload.

Other problems contributed to the delay. The 200-foot-tall rocket also was held past its original 1:24 p.m. launch time because a slight malfunction with the main fuel tank's fill-and-drain valve occurred during the topping operation. That glitch eventually was resolved. Also, one of NASA's Deep Space downrange tracking stations suffered a systems outage, but engineers quickly restored power.

Had Tuesday's liftoff proceeded on schedule, the New Horizons Observatory, as the spacecraft is formally named, would have been launched exactly nine years after the death of astronomer Clyde W. Tombaugh, who discovered Pluto in 1930.

The mission's launch window extends until Feb. 14.
