A successful launch for the CRS-5 mission would see the Dragon spacecraft arrive at the International Space Station on Monday, January 12th for a 6:00 AM (EST) berthing. If launch takes place on Tuesday, berthing would happen on Thursday.

NASA had previously estimated a 90% chance of “go” weather conditions for the original backup date of Friday, January 9th, and while there has not been formal declaration for Saturday, a similarly favorable outlook can be expected.

While SpaceX VP of Mission Assurance Hans Koenigsmann told reporters at pre-launch  press conference that high seas in the 16 foot range would not be a problem for the recovery platform, the issue of wind speeds was not addressed.

Launch coverage will begin at 3:30 AM EST on NASATV and at
