CPUT MDASat-1 Launch - SpaceX Mission Plan

An overview of the mission stages An overview of the mission stages SpaceX

SpaceX is targeting Thursday, January 13 for a Falcon 9 launch of Transporter-3 to orbit from Space Launch Complex 40 (SLC-40) at Cape Canaveral Space Force Station in Florida. The Transporter-3 will be carrying the CPUT MDASat - 1 constellation. The 29-minute launch window opens at 10:25 a.m. EST, or 15:25 UTC, and a backup opportunity is available on Friday, January 14 with the same window.

Falcon 9’s first stage booster previously launched Crew Demo-2, ANASIS-II, CRS-21, Transporter-1, and five Starlink missions. Following stage separation, SpaceX will land Falcon 9’s first stage on Landing Zone 1 (LZ-1) at Cape Canaveral Space Force Station.

Transporter-3 is SpaceX’s third dedicated rideshare mission, and onboard this launch are 105 spacecraft (including CubeSats, microsats, PocketQubes, and orbital transfer vehicles). A live webcast of this mission will begin about 15 minutes prior to liftoff.
