This is the archived website of the first two years of the MaCH-SR1 project during the first half of Phase I, and does not contain information about what is currently happening. For information on the current project, please visit:


The MaCH-SR1 hybrid rocket launch vehicle is a student-driven project that is currently under development at the University of Colorado in Boulder. The core team consists of eight students, but there are also advisors and many other interested people contributing in one way or another.

The specific long-term technical goal of this project is to build a sub-orbital rocket that is capable of:

  • Altitude goal of 75 miles (sub-orbital space flight)
  • Payload weight goal of 10 lbs
  • Reliable 12,000 lbf throttled LOX/HTPB hybrid engine
  • Recoverable/Reusable airframe

There are five phases to the project. Currently we are in Phase I.

  • Phase 0: Logistics- build up the team, get funding, set up accounts, lay down the infrastructure, learn rocket science, do initial designs. [Sept 2000 - July 2001]
  • Phase I: Design, build, and test the Mx1-L and M1-P class hybrid rocket engines. Data and experience gathered from these tests will be used to design the Phase II engines. [July 2001 - Now]

  • Phase II: Design, build, and test the M5-R class hybrid engines. These will be optimized for thrust and Isp, built for flight, and then flight-tested to gather data on static vs. dynamic performance.
  • Phase III: Design, build and test the M10-T class hybrid engine based off of experience and data from the prior engines, and prepare it for the first space shot. The MaCH-SR1 airframe will embody the M12-T hybrid engine.
  • Phase IV: Optimize the designs from flight data and build the MaCH-SR2. This rocket will be in active University service for use with research payloads that need high-altitude delivery.

As soon as testing starts, we'll have lots of documentation going into this website so that everyone can see what's going on with it
