Astronauts on space shuttle Discovery will enjoy some well-deserved off-duty time in the morning, then continue to transfer substance from the Leonardo Multi-Purpose Logistics Module and prepare for the final spacewalk of the mission in the afternoon.

Mission Specialists Clayton Anderson and Rick Mastracchio will end their day reviewing the new timeline for Tuesday’s finishing spacewalk and then spend the night in the Quest airlock, sealed off from the rest of the station, at a reduced atmospheric pressure.
