List of spacewalks 2000–2014 explained

This list contains all spacewalks performed between 12 May 2000 and 22 October 2014 where an astronaut fully or partially left a spacecraft.^[1]

Since 1981, NASA has measured spacewalk duration from when the suits went to internal power until the start of airlock re-pressurization. Roscosmos has always measured spacewalk duration from the time of hatch opening to hatch closure. These charts typically follow the agency's measurements of spacewalk duration, because those figures tend to be the most readily available, as they are most often provided by the agency.

2000–2004 spacewalks

Spacewalk beginning and ending times are given in Coordinated Universal Time (UTC).
