In brief

  1. Liftoff is scheduled for 11:54 a.m. CST Friday from Space Launch Complex 41 at Cape Canaveral Space Force Station.
  2. The Vulcan VC6L rocket (V-012) stands about 215 feet tall and generates roughly 3.9 million pounds of thrust at liftoff.
  3. Forecasters predict a 90% probability of favorable launch weather, ULA said.
  4. The mission is the first to use ULA's new Track A processing lane for Amazon flights.
  5. ULA's live launch blog starts at 7:30 a.m. EST Friday; the webcast begins about 20 minutes before liftoff.

A United Launch Alliance Vulcan rocket is cleared to loft 40 broadband satellites for Amazon's Leo constellation on Friday, with liftoff set for 11:54 a.m. CST from Cape Canaveral Space Force Station in Florida.

The mission, called Vulcan Leo 1, will fly from Space Launch Complex 41 and marks another major launch for Florida's Space Coast industry.

Forecasters put the odds of acceptable weather at 90%, according to ULA.

What happened at the readiness review?

Representatives from ULA, Amazon, the U.S. Space Force and the Federal Aviation Administration wrapped up the Vulcan Leo 1 Launch Readiness Review on Wednesday morning at the Advanced Spaceflight Operations Center.

ULA Launch Director Eric Richards led the review. The group checked the rocket's readiness, its 40-satellite payload and the infrastructure supporting the flight.

Officials also went over prelaunch processing work, technical assessments of the countdown and flight sequence, and the expected weather picture for launch day. Everything checked out. The rocket flies Friday.

Why is this launch a first for Amazon missions?

The flight introduces a new ULA processing configuration called the Track A lane, built specifically for Amazon missions as the company scales up its satellite network.

The setup includes:

  • A new Amazon Vertical Integration Facility, where the rocket gets stacked with its payload
  • A specialized Amazon Vulcan Launch Platform
  • Dedicated handling designed for Amazon's expanding deployment schedule

ULA builds, assembles and integrates its Vulcan rockets at a production facility in Decatur, Alabama, then ships them to the launch site.

How powerful is the rocket?

The mission uses ULA's Vulcan VC6L rocket, designated V-012. It stands roughly 215 feet tall and generates about 3.9 million pounds of thrust at liftoff.

Three features define this configuration:

  • Six side-mounted solid rocket boosters for extra punch off the pad
  • A Centaur V upper stage optimized for low Earth orbit
  • An extended-length payload fairing to house the 40 satellites

That thrust is what the heavy-lift rocket needs to push its full satellite payload into low Earth orbit, the region a few hundred miles up where broadband constellations like Leo operate.

When can you watch?

ULA will post live mission updates from its launch control center starting at 7:30 a.m. EST Friday through an automatically refreshing online blog.

The official launch webcast begins about 20 minutes before the planned liftoff.

What does this mean for the Space Coast?

The mission adds a major commercial satellite deployment to Cape Canaveral's crowded launch schedule, underscoring the Space Coast's growing role in building next-generation broadband satellite networks.

Bottom line: if the weather holds, Friday's flight delivers 40 more satellites toward Amazon's Leo network and debuts a launch lane built just for Amazon.
