A reminder

1 p.m. – Prelaunch news conference with representatives from NASA’s International Space Station Program, SpaceX and the U.S. Air Force’s 45th Space Wing.

Bet I can guess what the first question will be...

Thought I'd provide you with the generic forecast for May 1st at 4 AM, which is the closest hour-on-the-dot for the T0.

At 4 AM, it'll be mostly clear skies with a temperature of 73 degrees Fahrenheit, 11% precipitation, 25% cloud cover, 86% humidity, and east-southeast winds at 10 mph.

This just popped up. Power problem on ISS. Might affect CRS-17. "Discussions are underway to determine any impacts to SpaceX’s CRS-17 cargo resupply mission targeted for launch May 1."

Highlights of Science Launching on SpaceX's Dragon Spacecraft

NASA
Published on Apr 29, 2019

A SpaceX Dragon cargo spacecraft scheduled to launch May 1, 2019, takes supplies and a variety of scientific experiments to the International Space Station. Lifted into orbit by a Falcon 9 rocket from Cape Canaveral Air Force Station in Florida, the craft represents the 17th SpaceX Commercial Resupply Services contract mission for NASA.

Article by Bill Harwood. A failed MBSU has taken out power channels 3A and 3B, including one of the two Canadarm feeds. Dragon can’t launch until redundant power is restored.

Dragon Cargo Mission Launch No Earlier than May 3

NASA has requested SpaceX move off from May 1 for the launch of the company’s 17th commercial resupply mission to the International Space Station.

On April 29, the space station team identified an issue with one of the station’s Main Bus Switching Units that distributes power to two of the eight power channels on the station. There are no immediate concerns for the crew or the station. Teams are working on a plan to robotically replace the failed unit and restore full power to the station system. Additional information will be provided as it becomes available. The earliest possible launch opportunity is no earlier than Friday, May 3.
