Overview
Archive NoteThe EVA began at the Wentian airlock and involved debris protection and adjustment of external hardware, using China's Feitian suits.
The often-cited earlier NASA record of 8 h 56 min by Susan Helms and James Voss in 2001 uses battery time. A comparison must state which clock-start and clock-stop conventions apply.
