After many tests, SpaceX's first real try at launching a reusable rocket will attempt flight again in just a few minutes -- watch the live stream here or embedded after the break. Scrubbed due to weather a couple of days ago, the Falcon 9 rocket is once again facing gloomy skies, but according to launch control, everything is a go. Weather permitting, the launch is scheduled for 3:25PM ET, and there's more to it than just this rocket. SpaceX is already working on more reusable rockets, and you can see its latest one in a video embedded after the break. Also important is what's onboard the Dragon cargo ship this rocket is launching. Headed to the ISS, it's bringing new supplies and a pair of bendable legs for our friend Robonaut 2.
