SpaceX has announced that the SSO-A: Smallsat Express mission, previously scheduled for 28th November 2018, has been postponed due to extreme high-altitude winds at Vandenberg Air Force Base. A new launch date will be announced once coordinated with the range.
The SSO-A mission will carry several amateur radio satellites, including AMSAT’s Fox-1Cliff, FUNcube on ESEO, JY1-SAT, K2SAT, and ExseedSat.
The launch window each day opens at 18:31:47 UTC and extends for approximately 30 minutes.
