SpaceX is targeting Sunday afternoon for the launch of its Transporter-14 mission from Vandenberg Space Force Base.
The launch window for the Falcon 9 rocket is scheduled to open at 2:18 p.m.
SpaceX officials say the Transporter-14 rideshare mission will carry 70 payloads into low-Earth orbit.
Those payloads reportedly include microsatellites, nanosatellites, re-entry capsules, and orbital transfer vehicles.
Following stage separation, the Falcon 9 is set to land on the Of Course I Still Love You droneship in the Pacific Ocean.
If needed, SpaceX representatives say a backup launch window is available on Monday at 2:18 p.m.
