WATCH LIVE: SpaceX Falcon 9 Lights Up California Sky with 24 New Starlinks
SpaceX Launches Another Batch of Starlink Satellites from California
Quick Summary: SpaceX is sending 24 more Starlink internet satellites into space from Vandenberg Space Force Base in California. This is their 51st launch from the West Coast this year!
What’s Happening?
SpaceX is getting ready to launch a Falcon 9 rocket carrying two dozen Starlink satellites into orbit around Earth. These satellites will join thousands of others already circling our planet, helping provide internet access to people all over the world.

Meet the Rocket: Falcon 9 Booster B1103
The rocket doing the heavy lifting is a Falcon 9 first stage booster with the tail number B1103. Think of this booster like a reusable airplane — it flies to space, comes back down, and can be used again!
This Booster’s Resume (5th Flight!)
This will be B1103’s fifth trip to space. Here’s what it’s launched before:
- SDA-T1TL-E — Military missile-tracking satellites
- NROL-179 — National security mission for the National Reconnaissance Office
- Starlink 17-35 — Previous batch of Starlink satellites
- Starlink 17-42 — Another batch of Starlink satellites
- Starlink 17-49 ← This mission!
The Landing: Catching the Booster at Sea
Important Point: The Falcon 9’s first stage doesn’t just fall into the ocean — it flies itself back and lands on a floating platform!
How the Landing Works:
- Liftoff — Rocket launches from California
- Stage Separation — ~2.5 minutes in, the first stage (booster) separates from the second stage
- Boostback Burn — Booster flips around and fires engines to head back toward the landing zone
- Entry Burn — Engines fire again to slow down through the atmosphere
- Landing Burn — Final engine burn to gently touch down
- Touchdown — ~8.5 minutes after liftoff, the booster lands on the droneship
The Drone Ship: Of Course I Still Love You
- Name inspired by: A spaceship in Iain M. Banks’ sci-fi novels
- Location: Floating in the Pacific Ocean
- Landing Count: This would be the 163rd landing on this specific ship
- Total Falcon 9 Landings: Would be the 648th successful booster recovery overall
Why This Matters
Building the Starlink Constellation
- Goal: Provide high-speed internet everywhere on Earth
- Current Status: Thousands of satellites already in orbit
- This Launch: Adds 24 more satellites to the network
- Orbit: Low Earth Orbit (LEO) — much closer than traditional satellites, meaning faster internet!
West Coast Launch Leadership
- 51st launch from Vandenberg in 2024 — that’s nearly one per week!
- Shows SpaceX’s rapid, reliable launch cadence
- Vandenberg is perfect for southward launches into polar orbits

FAQ
What is Starlink?
Starlink is SpaceX’s satellite internet service. Think of it like a giant mesh of Wi-Fi routers in space that beam internet down to dishes on the ground. It’s especially useful for rural areas, ships at sea, airplanes, and places where laying fiber cables is too expensive or impossible.
Why does the rocket land on a boat instead of back at the launch pad?
Great question! The rocket launches southward over the Pacific Ocean. By the time the booster separates, it’s already far out over the water and moving fast. It doesn’t have enough fuel to turn around and fly all the way back to California — so a droneship (robot boat) waits in the ocean to catch it!
What does "B1103" mean?
B1103 is the booster’s serial number. The "B" stands for Booster, and "1103" is its unique ID. SpaceX tracks every booster like a car’s VIN number — they know exactly how many times it’s flown, what it’s launched, and how it performed.
How many times can a Falcon 9 booster be reused?
SpaceX has certified boosters for up to 20 flights (with inspections and refurbishment between flights). Some boosters have already flown 20+ times! The goal is to make rockets as reusable as airplanes.
What happens to the second stage (the top part of the rocket)?
The second stage carries the satellites the rest of the way to orbit. After deploying the satellites, it typically performs a deorbit burn and burns up in Earth’s atmosphere over the ocean. It’s the only part of the Falcon 9 that isn’t reused (yet!).
Fun Fact: The droneship name "Of Course I Still Love You" comes from a spaceship in Iain M. Banks’ "Culture" science fiction novels. SpaceX’s other droneships have similar literary names: "Just Read the Instructions" and "A Shortfall of Gravitas."
Stay tuned for launch updates — and clear skies for a successful mission!
