SpaceX CRS-4 Launch

In the early morning hours of September 21, 2014, a Dragon cargo spacecraft launched from SLC-40 in Cape Canaveral, Florida. It was the sixth flight for SpaceX's uncrewed Dragon cargo spacecraft, and the fourth SpaceX operational mission contracted to NASA under a Commercial Resupply Services contract. The mission brought equipment and supplies to the ISS, including the first 3D printer to be tested in space, a device to measure wind speed on Earth, and small satellites to be launched from the station.
