This will be the 50th Dragon vehicle to visit the International Space Station, including the Dragon 1 vehicles that were berthed to the orbiting lab. Docking with the Harmony module is anticipated Monday, Aug. 25, at 7:30 a.m. EDT (1130 UTC).

SpaceX called off a launch attempt in Texas Monday for the Super Heavy booster and Starship launch vehicle, blaming a bad valve on the first stage. The next launch attempt for the world’s largest rocket is scheduled for Thursday, depending on weather and a fix for the valve problem.

NASA officials say the International Space Station’s logistics chain was designed to absorb a launch failure like the mishap that destroyed an Orbital Sciences Corp. cargo craft in October, but pressure is on SpaceX to deliver supplies on time this year.
