Speaking to members of the media in the Kennedy Space Center’s Press Site auditorium, Dr. Michael Freilich of the Earth Science Division at NASA Headquarters in Washington, D.C., left, and Dr. Richard Blakeslee of NASA’s Marshall Space Flight Center in Huntsville, Alabama, discussed instruments to be delivered to the International Space Station on the SpaceX CRS-10 mission. The Lightning Imaging Sensor (LIS) is to measure the amount, rate and energy of lightning around the world. The SAGE III instrument is designed to study ozone in the atmosphere. A Dragon spacecraft is scheduled to be launched from Kennedy’s Launch Complex 39A on Feb. 18 atop a SpaceX Falcon 9 rocket on the company's 10th Commercial Resupply Services mission to the space station.

Mike Cisewski, Stratospheric Aerosol and Gas Experiment (SAGE) III Project manager at NASA’s Langley Research Center in Hampton, Virginia, speaks to members of social media in the Kennedy Space Center’s Press Site auditorium.

A SpaceX Falcon 9 rocket lifts off from Launch Complex 39A at NASA's Kenney Space Center in Florida. This is the company's 10th commercial resupply services mission to the International Space Station. Liftoff was at 9:39 a.m. EST from the historic launch site now operated by SpaceX under a property agreement with NASA. The Dragon spacecraft will deliver about 5,500 pounds of supplies to the space station, including the Stratospheric Aerosol and Gas Experiment (SAGE) III instrument to further study ozone in the atmosphere.
