Slide of the Month Extra: Manned Maneuvering Unit (MMU)


November 2023

Time to make: 1 hours

Finishing: 1 hour

Original design: MaxGrueter

The Manned Maneuvering Unit (MMU) was first craft to allow untethered astronaut space walks in 1984 during the  STS-41-B mission. On it's final mission on STS-51-A the MMU was used to capture the Palapa B2 and Westar 6 satellites and return them to the shuttle bay for return to earth for repair. Interestingly, the first planned device, the Astronaut Maneuvering Unit (AMU), was planned for Gemini/MOLE project using a rocket power propulsion. It was aboard Gemini 9A but because of difficulties during Gene Cernan's EVA the testing of the AMU was cancelled. Deke Slayton suggested in his autobiography, Deke!: U.S. Manned Space from Mercury to the Shuttle, the reason it was developed for the MOLE program was "they might have the chance to inspect somebody else's satellites". 

A very interesting 3d print to make as I needed lots of supports to successfully print it. When it was done, I first painted it with flat white Krylon fusion paint that sticks well to PLA plastic. Next I painted the visor with gold hobby paint. All the logos and stripes were done using water slide paper and I finished it off with a couple coats of poly
