A space station supply ship will have to wait another day to fly.
 
Orbital Sciences Corp. counted down to the final several minutes Monday evening for the launch of its unmanned Cygnus capsule from Wallops Island, Virginia. But a boat was in the restricted danger zone, and the liftoff was called off.
 
The Virginia-based company is expected to try again Tuesday.
 
Just five hours earlier, the space station had to sidestep a piece of treacherous junk. NASA says debris from an old, wrecked Russian satellite would have come dangerously close to the orbiting lab if not for the maneuver.
 
The unmanned Cygnus holds 5,000 pounds of space station cargo for NASA.
