SpaceX delays resupply mission to International Space Station with bad weather

Aug. 3 (UPI) -- SpaceX scrubbed plans to launch a re-supply mission to the International Space Station from Cape Canaveral Space Force Station in Florida on Saturday morning because of unfavorable weather conditions.

The Falcon 9 was scheduled to launch from Space Launch Complex 40 at 11:29 a.m. ET.

A backup launch opportunity is 11:02 a.m. ET Sunday. But the 45th Weather Squadron predicts only a 10% chance of favorable conditions then. Florida is affected by a tropical depression's rain and winds.

Also Sunday, SpaceX is planning to launch a Falcon 9 of 23 Starlink satellites from Vandenberg Space Force Base in California.

From Florida, this is the 21st Northrop Grumman Cygnus cargo spacecraft for NASA.

And it's the 10th flight of the first-stage booster supporting this mission, which previously launched Ax-2, Euclid, Ax-3, CRS-30, SES ASTRA 1P, and four Starlink missions. After first-stage stage separation, Falcon 9 will land on Landing Zone 1 at Cape Canaveral Space Force Station.

About 8,200 pounds of science and cargo supplies will be headed to the ISS.

The spacecraft includes water recovery technology, a process to produce stem cells in microgravity, studies of the effects of spaceflight on microorganism DNA, liver tissue growth and live science demonstrations for students.
