This episode of This Week @NASA reports on:

The Antares rocket remains at the Mid-Atlantic Regional Spaceport’s Pad 0-A at Wallops Flight Facility — awaiting launch on its first test flight under NASA’s Commercial Orbital Transportation Services, or COTS program. Orbital Sciences Corporation canceled the countdown during Wednesday’s initial launch attempt when a data umbilical connection prematurely separated from the rocket. On this demonstration flight, Antares will carry a simulated Cygnus spacecraft to orbit. The real Cygnus will deliver cargo to the International Space Station. Also, Orion’s Progress , Gathering for Impact!, Three More Planets for Kepler , Station Spacewalk, Moonbuggy Preps, Hubble’s Infrared Horsehead and more!
