ACME is focused on advanced combustion technology via fundamental microgravity research. The primary goal is to improve efficiency and reduce pollutant emission in practical terrestrial combustion. A secondary objective is fire prevention, especially for spacecraft.

Currently, ACME includes five independent experiments (see ACME Experiments below) investigating laminar, gaseous, non-premixed flames.

The ACME experiments will be conducted with a single modular set of hardware (see ACME Implementation) in the Combustion Integrated Rack (CIR) on the International Space Station (ISS).

An ACME precursor, Structure & Liftoff In Combustion Experiment (SLICE), was conducted in the ISS’ Microgravity Science Glovebox (MSG) in early 2012.

The ACME design is complete and the engineering hardware is being assembled for integrated testing. On-orbit testing is expected to begin in 2016 and continue for a few years.


  • Undergraduate engineering student Angel Rodriquez (U. Washington) is contributing to the project as a summer intern by conducting 2.2-second drop tests and analyzing experimental data.
  • Nine papers and 1 poster from the ACME project were presented at the 9th U.S. National Combustion Meeting held in Cincinnati, OH in May 2015. ACME plans were further described at this meeting as part of an exhibit on the Combustion Integrated Rack (CIR) research. Furthermore, astronaut Don Pettit, who conducted an ACME precursor, SLICE, on the space station in 2012, was the meeting’s banquet speaker.
  • An ACME fact sheet has been created.
