NASA ISS On-Orbit Status 24 September 2010
“Last night, during the 22S undock attempt the MRM2 hooks failed to open, causing deferral of the departure to tonight after a number of troubleshooting attempts. New times are: Undocking – 9:59pm EDT; Landing – 1:31am. Descent timeline will change commensurably.”
Crew Sleeps In, Prepares for Second Undocking Attempt
“Expedition 24 Commander Alexander Skvortsov and Flight Engineers Tracy Caldwell Dyson and Mikhail Kornienko will re-enter the Soyuz TMA-18 spacecraft for a second undocking attempt at 10:02 p.m. EDT. The first undocking attempt Thursday was delayed after hooks failed to open and mission controllers in Moscow had not received the expected “hatch locked” signal from the Poisk module.”
