Live flip rover simulation. 1000+ simulated parameters Thx @OfficialMoonDAO

Elon said the roadster sucks.. We rebuilt it in LunCoSim and drew the forces straight onto simulation, it is Al generated in our sim educational video In our model: 40 kN of suction against a 1.95-tonne car - about 2 g Worth making more of these? Hit like, or tell us what to take apart next

Just back from @IAC2026Antalya. We were ready to dive back into space... and then we saw the @Tesla Roadster doing a mid-air kickflip 🚀🚗 We couldn't ignore it - it’s the perfect use case for LunCoSim. We built this moving model from scratch with a single prompt. Next week, we tackle the physics: rigid-body, thermodynamics, valve electronics. While we share our IAC takeaways, the model will be cooking in the background. Engineers: how would you approach the thruster control logic? Drop your thoughts👇

🌕 LunCo at IAC 2026 — Antalya 🛠️ Hands-on side event: Run a Lunar Mission Together 7 Oct, 18:30–20:00 | DM us 🎤 Our talks 8 Oct, 11:05 | Hall 6 — Open-source simulation testbed for cooperative lunar surface ops 8 Oct, 16:12 | Hall 34 — Interoperability barriers and the case for open rover standards 9 Oct, 14:15 | G2 — Bridging architecture and systems engineering: simulation for lunar habitat design 👋 There @0xIonRod @CatFaber 💻 What we do LunCo makes open-source simulation software for lunar mission engineering. It runs on an ordinary laptop and lets a team run a mission together: driving rovers, managing power and comms, coordinating a lander — so lunar ops can be tested before hardware. Come find us after a session or DM us to set a time

In Modelica it becomes equations — sun angle, battery state of charge, the draw from driving and comms. In USD it becomes a place: a slope near the pole, at an hour when the terrain casts a shadow across the panel. Only the 3 step tells you whether the 1st one holds, because the shadow is part of the physics. It is still an answer under your assumptions, not a validated design.

Our IAC session is now an official International Moon Day 2026 event. IMD runs worldwide Jul–Oct under the UN proclamation, organised by @MoonVillageAssn Antalya, 7 Oct: bring a laptop, take a role, and the room runs a lunar surface mission together in our open-source simulator. Free. Same event, one registration — the IMD listing just puts it on the global map.

LunCoSim Update for @Artizen youtu.be/Mdze7MvcFf4 (Collabortavite interactive multiphysics robotic cosimulator for Space Mission)

Depending on the terrain you rover driving on your solar production changes significantly

Summer Space School: wrapped LunCoSim's first external stress test — driven for a week by testers aged 15 to 50. Real bugs filed, physics validated against real LRO terrain, first-day operator curriculum proven in the wild. Plus one moment for the history: full mission simulation, 250 participants, run 55 years to the day after the first drive on the Moon — on the same terrain. The operator pipeline is open. Free, open source: ⭐️ Workshop for your team/uni? DMs open 🚀

Proud to be among the contributors to the Modelica Association’s latest newsletter. At LunCoSim, we are continuing to advance the integration of #OpenUSD and #Modelica for next-gen simulation workflows. Thanks to the Modelica Association for the feature! Check out our article and the full list of vendor updates below. linkedin.com/posts/modelica-…

🚀 We’re in the Modelica Newsletter 2026-02 Vendor News! Meet LunCoSim: an open‑source, Rust‑based simulator for lunar & orbital mission engineering. Multi‑physics (electrical, thermal, propulsion, GNC…) is described in Modelica and compiled in‑process by rumoca. The kicker? Edit your assembly and it regenerates + recompiles on the fly—no restart. USD prims name Modelica classes, connections become connect() equations. Seamless. Read the full piece 👉 modelica.org/newsletter/2026…

For high-fidelity simulation we generate modelica models on the fly. The model is being tested near Apollo 15 landing site. Everything nominal, except rover can move with battery depleted. But it turned out to be a feature - motors have unlimited energy for easier of testing. PS The model has around 100 trackable parameters

Today LunCoSim met its toughest users yet: the Summer Space School - 250 participants, and the first operator cohort at the console this morning. Fewer than 10 machines have driven on the Moon in 55 years. Dozens launch this decade. Someone has to train the operators. The part we care most about: this is LunCoSim's first external stress test.
