Mission Roadmap
From initial setup to full-scale development — every milestone on our journey to reusable space access.
Established Cosmo Crawler with a clear vision: build a fully reusable launch vehicle using hybrid landing technology to lower cost and risk for space access.
Researched next-generation rocket propellants and selected an electric pump feed architecture — enabling cleaner combustion and simplified engine design.
Designed the reaction control engine in CAD with full thermal and flow considerations. Partnered with Onshape and cloud tools for collaborative engineering.
3D-printed engine components in super aluminum-silicon alloy (Al-Si) — an aerospace-grade material that enables rapid iteration and complex internal geometries.
Assembled the first reaction control engine prototype with electric pump motors and integrated feed lines — validating mechanical fit and system integration.
Step 06 — Cold Fire Test
Real ignition and burn footage from our reaction control engine — recorded from two camera angles on the test stand.
Side-angle capture showing engine ignition, flame stability, and exhaust plume during the cold-fire test.
Second camera perspective documenting the complete firing event from another vantage point.
One of the critical parts of a rocket engine is the ignition system. We developed a small methane + gaseous oxygen based direct-ignition ignitor. The test article melted during the test, but the experiment successfully validated several aspects of the design.
The test also produced a clearly visible Mach diamond, indicating a supersonic exhaust jet. While an ignitor does not necessarily need to operate with a supersonic jet, the observed flow characteristics are relevant to improving ignition reliability, particularly for our kerolox-based Mugger engine.
Based on the results, we are incorporating design changes and will conduct another test with an updated ignitor.
Scaling propulsion to the CAIMAN 2000 — a micro-category liquid engine delivering 1,000 kgf at 60 bar and 2,200+ kgf at full thrust, with continuous restart capability.
Developing hybrid landing systems that combine proven recovery methods with novel control logic — reducing landing risk and enabling rapid vehicle turnaround.
Integrating engines, avionics, structures, and landing systems into a complete reusable launch vehicle architecture ready for ground and flight testing.
The culmination of every milestone — demonstrating reusable launch capability and proving that affordable, reliable access to space is within reach.
