When Does SpaceX’s Starship V3 Blast Off? The Full Flight‑12 Timeline

SpaceX has been teasing the next big step for its massive Starship system – the V3 configuration, slated for what the company calls Flight 12. After a string of sub‑orbital hops and a few higher‑altitude tests, this will be the first flight that truly pushes the vehicle toward orbital capability.

So, when will the rockets roar into the sky? The launch window is pegged for a narrow slot on April 20, 2024, lasting roughly 15 minutes. That window opens at 12:38 p.m. UTC and closes at 12:53 p.m. UTC. In Texas time (CST), that translates to 7:38 a.m. to 7:53 a.m., right when the desert air is still a bit cool – a condition engineers love.

Here’s a quick glance at the day‑of schedule:

• 06:00 CST – Arrival and prep: Workers, media, and the occasional curious on‑lookers pour into the Boca Chica launch site. Trucks roll in, equipment is double‑checked, and the crew runs through safety briefings.
• 07:00 CST – Tanking begins: The gigantic Super Heavy booster starts filling with liquid methane and liquid oxygen. It’s a slow, deliberate process – you can hear the hiss of cryogenic fuels as they cascade into the tanks.
• 07:30 CST – Final checks: The flight director and his team run through a checklist that feels almost endless. Sensors, avionics, software loads – everything gets a once‑over.
• 07:45 CST – Go/No‑Go poll: Engineers vote. If the majority says “go,” the countdown proceeds. If not, the launch is scrubbed and they’ll revisit the timeline.
• 07:50 CST – Countdown resumes: A series of automated events kick in – autopilot systems engage, guidance computers align, and the vehicle readies its engines.
• 12:38 UTC – Launch window opens: The clock starts ticking. If the weather stays within limits (no high winds, lightning, or thick clouds), the engines will fire.
• 12:40 UTC – Liftoff (if all is well): Super Heavy’s 33 Raptor engines roar, lifting the 5‑million‑pound Starship off the pad. The booster separates after about two minutes, and the Starship continues toward orbit.

What’s the mission’s goal? In plain English, SpaceX wants to prove that the upgraded V3 design can survive the stresses of a near‑orbital flight, re‑enter the atmosphere, and land safely – a full “hop” that mimics the profile of a future Mars mission.

There’s also a lot of fanfare built into the event. A live‑stream will be hosted on SpaceX’s website and YouTube channel, with a dedicated commentary crew explaining each phase as it happens. Social media will light up with #StarshipV3 and #Flight12 – expect a mix of awe‑struck memes and technical deep‑dives.

If the launch is delayed, the reason will likely be weather. The Texas Gulf Coast can be fickle; a sudden thunderstorm or gusty winds can push the window to the next day. SpaceX usually communicates any shift via a brief tweet, so keep an eye on their official account.

All told, the Starship V3 flight marks a pivotal moment. It’s not just another rocket launch; it’s a concrete step toward the massive, reusable spacecraft that could someday ferry humans to the Moon, Mars, and beyond. Whether you’re a die‑hard space nerd or just someone who enjoys watching a massive metal bird take off, this launch is worth marking on your calendar.
