United Launch Alliance’s Kuiper KA-01 mission was scrubbed last night due to persistent high winds and offshore showers. SpaceX has the range scheduled for a Starlink launch from KSC this evening, so ULA will be pushed back to at least Monday.

According to ULA CEO Tory Bruno on X.com, “Mighty Atlas’ count was very clean. Unfortunately, weather stayed rough. [We] appreciate support from the USSF Weather team.”

The Monday date is pending Eastern Range approval, among others, and may shift. As always, stay tuned.

Starlink 12-17

SpaceX is planning to launch another set of Starlink satellites to orbit from pad LC-39A at Kennedy Space Center this evening. The launch window opens at 9:54 PM ET and extends to 1:43 AM Friday morning. According to SpaceX, “If needed, additional launch opportunities are also available on Friday, April 11 starting at 9:15 p.m. ET.”

Mission	Falcon 9 Block 5 | Starlink Group 12-17
Organization	SpaceX
Location	Kennedy Space Center, FL, USA
Rocket	Falcon 9 Block 5
Pad	Launch Complex 39A
Status	Go for Launch
Status Info	Current T-0 confirmed by official or reliable sources.
Window Opens	Thursday, 04/10/2025 9:54:40 PM EDT
Window Closes	Friday, 04/11/2025 1:43:00 AM EDT
Destination	Low Earth Orbit
Mission Description	A batch of 21 satellites for the Starlink mega-constellation—SpaceX’s project for a space-based Internet communication system.

After concluding its duty powering the payload towards orbit, the first stage booster, B1083, will land on ASDS ‘A Shortfall of Gravitas’ which will be stationed on the Atlantic Ocean near The Bahamas. Since the booster is not returning directly to the Cape Canaveral region after liftoff, there will not be a sonic book over the Space Coast region.

Weather looks good, with only a 5% chance of a weather-related range violation. That said, it should be a beautiful evening to go to space.

This will be the 10th flight of B1083. Previously, it has launched Crew-8, Polaris Dawn, CRS-31, Astranis: From One to Many, IM-2, and four Starlink missions.

The trajectory is southeast, and Starlink 12-17 will pass just east of The Bahamas on its way to orbit.

ULA Atlas V Kuiper KA-01 Now Slated For Monday

Due to the SpaceX launch, this evening is not an option for United Launch Alliance to fly Atlas V and the Kuiper KA-01 mission. At this point in time, secondary sources (FAA, etc) are pointing to an attempt this coming Monday, April 14th.

Mission Description	Project Kuiper is a mega constellation of satellites in Low Earth Orbit that will offer broadband internet access. This constellation will be managed by Kuiper Systems LLC, a subsidiary of Amazon. It is planned to be composed of 3,276 satellites, projected to be placed in 98 orbital planes across three orbital layers at altitudes of 590 km, 610 km, and 630 km.

Keep in mind that is not official, and it could easily change. Stay tuned for any schedule shifts.
