# Tag name for MMU, SAFER, and similar?

What would be a good tag name for devices that help propel a spacewalking astronaut? Such devices include the MMU, SAFER, and the canned gas that Ed White used during his spacewalk. I have a pending question for the "jet boots" that were considered for Skylab.

Suggestions?

• astronaut-propulsion seems like an okay variation, if nothing else better is suggested. Jun 17 at 20:47
• astronaut-articulation? (humor)
