Project Excelcius

The flagship mission of LetSpace is to send a rocket into internationally recognized space, or above the Karman Line (100km, 62 miles or 328,000 ft): Project Excelcius. The Excelcius launch vehicle will be a fully-reuseable, two-stage, solid-fueled sounding rocket, entirely designed, built and operated by undergraduate students. This includes casting handmade motors and building our own flight computers. The primary objective is to return video and pictures of the Earth from space. Currently, Technology Demonstration Rockets (TDR) and Sub-scale SpaceShot Prototypes (S4P) are being produced to develop the technologies and techniques needed to design and build such a vehicle, as well as enhance organizational experience. The STELLA flight computer has already been mostly completed and is gaining reliablilty with every test flight. Read more on the latest updates here. 

Project Trepid

Project Trepid is LetSpace's motor development program. LetSpace anticipated the need for custom motors for a spaceshot and has been working to develop the capabilities for such a motor's construction since 2023. The project has three phases.

Phase 1: Develop low-power rocket motor. This involves developing the ideal propellant mixture, building a test stand and creating nozzle machining practices and techniques. This phase was completed in 2024.

Phase 2: Develop a high-power rocket motor. This required scaling up the machining and propellent casting, as well as development of a program that can accurately measure thrust of the motors. This phase was completed in 2025.

Phase 3: Fly the Phase 2 rocket motor in a real rocket flight. This phase is currently in progress
