Starship Space Program is out in early alpha.
A Starship + Super Heavy flight sim for Windows PC: hops, hot staging, the booster catch, on to orbit. Built in Unreal Engine with real orbital physics.
Play it now on Patreon: patreon.com/StarshipSpacePro…
Made with @UnrealEngine
🚀 Starship Space Program Alpha 0.2.4 is out!
This one rebuilds the game's foundations so Starship and Super Heavy fly the way the real ones do.
What's new:
• A new physics core: gravity from the Earth, Moon, Sun and planets, plus the Earth's true shape and spin
• Real Starbase winds from Brownsville weather-balloon data, with gusts
• Every Raptor started, shut down and throttled on its own, down to 40%
• Simulated tanks: boil-off, pressure, slosh and heating, with the balance point shifting as they drain
• An autopilot that flies countdown to orbit like Flights 13 & 14: max-Q, MECO, hot staging, booster flip and boostback
• A default flight to a 275 km orbit that deploys 26 Starlink V3s
• Countdown voice calls, a real night sky with the Milky Way, an updated Ship and the Pad 2 tower
It's not the full thing yet. Re-entry, landings and tower catches are being rebuilt for the new physics, and they're next.
📱 A mobile beta featuring the whole low-altitude test campaign is also coming this month on all mobile platforms.

Thank you all for the love on the Starship telemetry tool 🙏
So here's a big one: payload deploy is now in. Watch the door open and the sats roll out, all replayed from real webcast telemetry.
FREE. In your browser.

I'm very happy you guys liked it! It was made possible with all the research I've made for the development of @programstarship . So if sometime you want to fly it, not just watch it, check out Starship Space Program @ starshipspageprogram.com: hot staging, booster + ship chopstick catches, a new Daily Catch every day. Early alpha out now on Patreon (Win/Mac) 👇

Starship flights' telemetry data visualized: free, and right in your browser:
Since I had all that telemetry data lying around, and also all that code from StarshipSpaceProgram, I figured why shouldn't I put 1 and 1 together? so here it is, and FREE for all. Starship webcasts' telemetry visualization. Runs on browser!
There's a lot of margin for improvement, so let me know what you think!

Booster 22 just lit up Pad 2 at Starbase this morning 🔥 and Flight 15 is going to try to catch BOTH the booster and the ship.
I couldn't wait, so I've been doing exactly that in my game 😅
Starship Space Program is a fan-made Starship + Super Heavy spaceflight sim I'm building in Unreal Engine, and version 0.2.0 of the early alpha is out now for patrons:
⏱️ NEW: a real countdown, webcast-style UI and the full Pad 2 tower launch sequence, with new engine plumes
🚀 Low-altitude hops and high-altitude test flights
🔥 Hot staging on the way up
🥢 Super Heavy AND Ship catches on the tower
🎓 Flight School and challenges with medals, plus a new Daily Catch every day
🌍 Low Earth orbit and interplanetary flight planners (Moon and Mars landings come later)
📸 Replays, photo mode, save and load anywhere
It's an early alpha, so things will break and change, and what you tell me shapes what comes next.

Right now I'm working on a major interface overhaul for @programstarship. I really want it to be as familiar as kerbal, but I just HAVE to make the bottom UI look like SpaceX Starship launch webcast, so I'm figuring out where to put UI elements around, and how to make it look consistent with the webcast UI aesthetics.
Luckly @UnrealEngine makes it really a breeze to work with UI in UMG.
Starship Space Program retweeted
I've been quietly building a game for the past few years. and today it finally goes out the door! 🚀
Until recently, I had no idea what shape it would take. It turned into Starship Space Program: a Kerbal-like flight sim for Starship and Super Heavy. You fly the hops, hot staging, the booster catch on the tower, and on to orbit, with real orbital physics. Starbase is built from lidar, so the pads and the tower are exactly where they really are. Catching the booster in the chopsticks yourself is as good as it sounds.
It's an early alpha, and that's the point: I want the people who love this stuff to shape what it becomes from here. Things will break. Tell me what does.

Top tiers get a Cybertruck, and a Roadster with cold-gas thrusters, to drive around Starbase.
