secured the boom to the outside of the space station. After finishing that task, Foreman inspected a jammed rotating joint that has restricted the use of a set of solar wings for months. NASA hopes to have a plan for dealing with the jammed joint by the end of the month, space station flight director Dana Weigel said. March 24 (Flight day 14) The crews of Space Shuttle Endeavour and the International Space Station completed their last full day together. Much of the astronauts' morning was off-duty time. Afterward, the crews wrapped up transfers of equipment and supplies between Endeavour and the station, and out the tools needed for undocking and subsequent activities. The STS-123 and Expedition 16 crews also held a joint crew news conference, answering questions from members of the media on Earth. March 25 (Flight day 15) The hatches between Endeavour and the International Space Station closed around 21:49 UTC, ending a 12-day stay at the ISS, with a scheduled undocking of 23:57 UTC. Because of problems with a command sent to solar arrays in the ISS, the undocking was delayed 28 minutes and occurred at 00:25 UTC. March 26 (Flight day 16) The crew of Space Shuttle Endeavour spent Tuesday getting ready for its journey home and the end of the STS-123 mission. Early in their day, the crew members performed a test of the thrusters that will be used to position the orbiter for re-entry and the control surfaces for its flight through the atmosphere. The STS-123 astronauts also set up the recumbent seat for Mission Specialist Léopold Eyharts, who joined the crew of Endeavour on the International Space Station. The recumbent seat is a special seat designed to reduce the stress of gravity on those who have spent long periods of time in the weightless environment of space. March 27 (Flight day 17, landing) Flight controllers gave a no-go on de-orbit for the first landing opportunity at 23:05 UTC (19:05 EDT), due to unfavorable weather conditions at the Shuttle Landing Facility at Kennedy Space Center. Weather conditions were acceptable for the second landing opportunity, planned for 00:39 UTC March 27, 2008 (20:39 EDT March 26, 2008). The landing occurred at the Shuttle Landing Facility, and was the sixteenth night landing of the Space Shuttle at KSC, 22nd Shuttle night landing overall. Coincidentally, this mission also began with a night launch. The second landing opportunity
