SpaceX’s Starship Flight 12: Countdown to the Next Orbital Leap

It’s almost surreal to watch another massive stainless‑steel booster line up on the launch pad. By the time the clock hits 12:00 p.m. CDT on May 18, 2026, SpaceX hopes Starship Flight 12 will finally break the sound barrier on its maiden orbital attempt.

Since the last test flight, the team at Boca Chica has been pulling all‑nighters—literally. They’ve swapped out the Raptor 2 engines, re‑inspected the heat shield tiles, and even gave the massive nose cone a fresh coat of protective paint. Engineers say the new “full‑flow” Raptor upgrade promises a 10‑percent thrust bump, which could make a noticeable difference when the vehicle hits vacuum.

Here’s the live‑update timeline you’ll want to keep an eye on:

• 08:00 CDT – Final Systems Check: Ground controllers will run a complete diagnostics sweep, confirming that fuel lines, avionics, and the new methane‑liquid oxygen tanks are all green.
• 09:30 CDT – Weather Briefing: A quick look at the Gulf of Mexico’s afternoon forecast. So far, the models show clear skies and winds under 12 knots—just the sweet spot for a clean ascent.
• 11:00 CDT – Fueling Begins: Approximately 1,200 tonnes of liquid methane and liquid oxygen will flow into the vehicle, a process that can take up to 90 minutes.
• 12:00 CDT – Liftoff: The Super Heavy booster will roar to life, delivering about 72 meganewtons of thrust. If all goes well, the stack should clear the pad in roughly 2.5 minutes.

What’s different this time? For starters, Flight 12 will carry a new set of scientific payloads for NASA’s Artemis program, including a compact lunar‑surface sensor that will test radiation shielding in deep space. There’s also a high‑resolution Earth‑observation camera, intended to give us fresh views of weather patterns across the Pacific.

And, of course, the big question on everyone’s mind: will Starship reach orbit? The company says the flight profile includes a planned engine shutdown at 150 kilometers altitude, followed by a controlled re‑entry burn. If the vehicle survives that stretch, it will splash down in the Atlantic after a 12‑hour orbit.

Space enthusiasts worldwide have already set up livestreams, and the official SpaceX YouTube channel promises multiple camera angles—from the pad to an onboard view of the first stage separating. So grab your popcorn, settle in, and keep those notifications on. This could be the moment we finally see a fully reusable star‑ship soar beyond Earth’s atmosphere.
