The Dragon spacecraft will deliver 6,000 pounds of supplies, such as the Neutron star Interior Composition Explorer, or NICER, designed to study the extraordinary physics of these stars, providing insights into their nature and behavior.

A Falcon 9 rocket stands ready for liftoff at the Kennedy Space Center's Launch Complex 39A. The historic launch site now is operated by SpaceX under a property agreement signed with NASA. The rocket will boost a Dragon resupply spacecraft to the International Space Station. Liftoff is scheduled for 10:01 a.m. EST on Feb. 18. On its 10th commercial resupply services mission to the space station, Dragon will bring up 5,000 pounds of supplies, such as the Stratospheric Aerosol and Gas Experiment (SAGE) III instrument to further study ozone in the atmosphere. Once mounted on the space station, SAGE III will measure the Earth’s sunscreen, or ozone, along with other gases and aerosols, or tiny particles in the atmosphere.

Behind him, from left, are Kennedy Space Center Director Bob Cabana and Gwynne Shotwell, president and chief operating officer of SpaceX. On Feb. 18, a Falcon 9 rocket with a Dragon spacecraft atop is scheduled to lift off from the launch pad for the SpaceX CRS-10 mission. The historic site is where American astronauts first launched to the moon and was last used in 2011 for the final mission of the Space Shuttle Program. In April 2014, NASA officials signed a 20-year property agreement with SpaceX for use and operation of the launch pad for their Falcon 9 and Falcon 9 Heavy rockets. The SpaceX CRS-10 liftoff is another milestone further establishing Kennedy as a premier, multi-user spaceport. The Dragon spacecraft will deliver 5,000 pounds of supplies and research materials to the space station.

CAPE CANAVERAL, Fla. -- A crawler-transporter begins its climb toward Mobile Launcher Platform-2, or MLP-2, on the hardstand at Launch Pad 39A at NASA's Kennedy Space Center in Florida. Operations are underway to move the MLP to a nearby park site in Launch Complex 39. The historic launch pad was the site from which numerous Apollo and space shuttle missions began and is beginning a new mission as a commercial launch site. NASA signed a property agreement with Space Exploration Technologies Corp., or SpaceX, of Hawthorne, California, on April 14 for use and occupancy of the seaside complex along Florida's central east coast. It will serve as a platform for SpaceX to support their commercial launch activities. For more information on Launch Pad 39A, visit http://www.nasa.gov/centers/kennedy/pdf/167416main_LC39-08.pdf.
