have decided to postpone the launch of the Antares rocket and its
Cygnus cargo craft on the first Orbital commercial resupply mission to
the space station to no earlier than Wednesday, Jan. 8 due to the
forecast of cold temperatures for Tuesday, Jan. 7 at the launch site at
NASA’s Wallops Flight Facility in Virginia.
The forecast for Wednesday also calls for cold temperatures, but the
station program and Orbital plan to revisit the weather forecast at the
beginning of the week. The main concern with the weather is the cold
temperatures coupled with likely precipitation. Orbital says the Antares
rocket has a lower limit temperature constraint of 20 degrees
Orbital still plans to roll out its Antares rocket to Launch Pad 0A at
Wallops on Saturday night because the weather is forecast to be
favorable at that time.
The launch time for Wednesday, Jan. 8 is 1:32 p.m. Eastern time. NASA TV coverage of launch will begin at 1 p.m.
A launch on Wednesday will result in a grapple of Cygnus by the
Expedition 38 crew aboard the station on Sunday, Jan. 12 at 6:02 a.m.
NASA TV coverage will begin at 5 a.m. Coverage of the installation of
Cygnus on the Earth-facing port of the Harmony module will begin at 7
