'''Simplified Aid For EVA Rescue''' ('''SAFER''') is a small, self-contained, propulsive backpack system ([[jet pack]]) worn during [[spacewalk]]s, to be used in case of emergency only. If an untethered astronaut were to lose physical contact with the vessel, it would provide free-flying mobility to return to it. It is worn on spacewalks outside the [[International Space Station]] (ISS), and was worn on spacewalks outside the [[Space Shuttle]]. So far, there has not been an emergency in which it was needed.<ref name="day8-92">{{Cite web|url=http://science.ksc.nasa.gov/shuttle/missions/sts-92/sts-92-day-08-highlights.html|title=STS-92 Day 8 Highlights|access-date=October 6, 2008|publisher=NASA|year=2000|author=NASA}}</ref><ref name="A Flying Astronaut Over Earth">{{Cite web|url=http://www.sai.msu.su/apod/ap011002.html|title=Astronomy Picture of the Day A Flying Astronaut Over Earth  |access-date=October 6, 2008|publisher=NASA|year=2001|author=APOD}}</ref> SAFER is a small, simplified version of the [[Manned Maneuvering Unit]] (MMU), which was used for regular maneuvering.<ref name="assembly">{{Cite web|url=http://images.jsc.nasa.gov/luceneweb/caption.jsp?searchpage=true&keywords=SAFER&textsearch=Go&hitsperpage=5&pageno=3&photoId=S93-50137|title=SAFER Assembly|access-date=October 6, 2008|publisher=NASA|year=1993|author=NASA|url-status=dead|archive-url=https://web.archive.org/web/20110613224209/http://images.jsc.nasa.gov/luceneweb/caption.jsp?searchpage=true&keywords=SAFER&textsearch=Go&hitsperpage=5&pageno=3&photoId=S93-50137|archive-date=June 13, 2011}}</ref>
