The fifth SpaceX cargo mission to the International Space Station (ISS) under NASA's Commercial Resupply Services contract now is scheduled to launch about 6:18 a.m. EST Tuesday, Jan. 6, from Space Launch Complex 40 at Cape Canaveral Air Force Station in Florida. NASA Television coverage of the launch begins at 5 a.m.

The new launch date will provide SpaceX engineers time to investigate further issues that arose from a static fire test of the Falcon 9 rocket on Dec. 16, and will ensure proper sun angles for thermal and operational conditions to berth Dragon.

The prelaunch news conferences also have moved to Monday, Jan. 5, at the agency's Kennedy Space Center in Florida. All briefings, which are subject to a change in time, will air live on NASA TV and the agency's website.

The first briefing of the day will air at noon and cover the Cloud-Aerosol Transport System (CATS) Earth science instrument headed to the space station. Participants for this briefing will be:

Julie Robinson, ISS Program chief scientist at NASA's Johnson Space Center in Houston

The second briefing will air at 1:30 p.m. and cover some of the numerous science investigations headed to the space station. Participants for the science briefing will be:
