SpaceX experienced multiple weather-related delays before successfully launching its Falcon 9 rocket carrying the Starlink 10-30 mission from pad 40 at Cape Canaveral Space Force Station on August 4, 2025. The launch time was repeatedly pushed back from an initial 1:03 a.m. ET to 3:57 a.m. ET due to persistent thunderstorms in the area. Following this, SpaceX prepared for the KF-02 mission to deploy 24 satellites for Amazon's Project Kuiper, also from pad 40. The launch was initially scheduled for 10:02 a.m. ET on August 7, 2025, but was postponed to 10:17 a.m. ET and ultimately scrubbed due to vehicle issues, with SpaceX citing the need for additional vehicle checkouts. The company announced plans to attempt the launch again on August 8, 2025. The KF-02 mission marks the second batch of satellites for Amazon's broadband constellation and the first flight of the Falcon 9 booster B1091.
