The briefing start time has been pushed back to 6 p.m. EDT.
From the launch briefing...Launch is on for Friday, and if weather doesn't permit, launch is possible on Saturday for a full duration mission. The non-working phase of the freon motor will be turned off for the ride uphill. Even if no launch this week, the fuel cell won't be swapped out for flight in late September. The press was wringing their hands (hehe).
