Prelaunch activities are well under way at Space Launch Complex 41 on Cape Canaveral Air Force Station, where NASA's MAVEN spacecraft and its ride into space, the United Launch Alliance Atlas V rocket, are being readied for liftoff at 1:28 p.m. EST. The countdown has resumed following a built-in hold at the T-2 hour mark, and the launch team is beginning the process of loading cryogenic propellants aboard the rocket.
Weather forecasters continue to expect a 60 percent chance of favorable conditions during the two-hour launch window.
