UPDATE: The mission has been postponed because of repairs needed to a pump on the International Space Station, according to NASA. Crew members aboard the space station are slated to take space walks Dec. 21, 23 and 25 to replace the pump, used to keep equipment cool.
A launch to restock the International Space Station with provisions and scientific equipment is expected to be visible across Maryland on Thursday, though it could be delayed.
NASA and Orbital Sciences Corp. have scheduled the launch of an Antares rocket from Wallops Flight Facility on the Delmarva peninsula for no earlier than 9:19 p.m. on Dec. 19. The launch had previously been scheduled for a day earlier but a decision to push it back was made because of a malfunction.
The rocket was rolled out to its launch pad Tuesday morning, according to Orbital, though no decision on a Thursday launch had been made. An update was expected from NASA Tuesday or Wednesday.
