At T-60 minutes, all remains on track for the SpaceX-3 mission to lift off on time at 3:25 p.m. EDT. The spacecraft carries no people, but is loaded with about 5,000 pounds of supplies, experiments and equipment for the International Space Station and its crew of astronauts. Six people live on the space station now conducting research and learning about long-duration spaceflight. Launch Weather Officer Mike McAleenan just improved the forecast to a 60 percent chance of acceptable conditions at launch time. Again, all conditions are “go” now and there are no technical concerns.
