CAPE CANAVERAL, FL (WAFF) -

About 5,000 pounds of NASA science investigations and cargo are on their way to the International Space Station aboard SpaceX's Dragon spacecraft. The cargo ship launched on the company's Falcon 9 rocket from Space Launch Complex-40 at Cape Canaveral Air Force Station in Florida early Sunday morning.

The mission is the company's fourth cargo delivery flight to the space station through a $1.6 billion NASA Commercial Resupply Services contract. Dragon's cargo will support experiments to be conducted by the crews of space station Expeditions 41 and 42.

One of the new Earth science investigations heading to the orbital laboratory is the International Space Station-Rapid Scatterometer, a remote sensing instrument that uses radar pulses reflected from the ocean's surface from different angles to calculate surface wind speed and direction. This information will be useful for weather forecasting and hurricane monitoring.

Dragon also will deliver the first-ever 3-D printer in space. The technology enables parts to be manufactured quickly and cheaply in space, instead of waiting for the next cargo resupply vehicle delivery. The research team also will gain valuable insight into improving 3-D printing technology on Earth by demonstrating it in microgravity.

Other experiments and equipment carried aboard the spacecraft include biomedical hardware and a plant study research project.

Dragon is scheduled to be grappled Tuesday morning. Dragon is scheduled to depart the space station in mid-October for a splashdown in the Pacific Ocean, west of Baja California, bringing from the space station almost 3,200 pounds of science, hardware and crew supplies.

NASA recently awarded contracts to SpaceX and The Boeing Company to transport U.S. crews to and from the space station with the goal of certifying those transportation systems in 2017.
