Space station astronauts focused today on preparations for a contingency spacewalk to be conducted in the next week or so. Meanwhile station program managers and SpaceX officials are working toward scheduling dates for the next launch attempt for Dragon cargo spacecraft and that contingency spacewalk, while managing all this around the planned undocking and redocking of a Russian cargo craft next week. Monday's launch attempt of the SpaceX Dragon cargo craft, loaded with nearly 5,000 pounds of supplies and experiment hardware, was scrubbed due to a helium leak on the Falcon 9 rocket's first stage. The next launch opportunity would be Friday at 3:25 p.m. EDT if the issue can be resolved.
