NASA and industry leaders speak to NASA Social participants about the agency's Transiting Exoplanet Survey Satellite (TESS) in the Press Site auditorium at Kennedy Space Center in Florida. Speaking to the group from center, are Martin Still, TESS Program Scientist, NASA Headquarters, and Jessie Christiansen, Staff scientist, NASA Exoplanet Science Institute, California Institute of Technology. At far left is Jason Townsend, NASA Communications. TESS is the next step in the search for planets outside of our solar system. The mission will find exoplanets that periodically block part of the light from their host stars, events called transits. The satellite will survey the nearest and brightest stars for two years to search for transiting exoplanets. TESS will launch on a SpaceX Falcon 9 rocket from Space Launch Complex 40 at Cape Canaveral Air Force Station no earlier than 6:32 p.m. EDT on Monday, April 16.

The two-stage SpaceX Falcon 9 launch vehicle lifts off from Space Launch Complex 40 at Cape Canaveral Air Force Station, carrying the SpaceX Dragon resupply spacecraft to the International Space Station. Liftoff was at 5:42 a.m. EDT on Friday, June 29, 2018. On the company’s 15th Commercial Resupply Services mission to the International Space Station, Dragon is filled with supplies and payloads, including critical materials to support several science and research investigations that will occur during Expedition 56. The spacecraft’s unpressurized trunk is carrying a Canadian-built Latching End Effector, or LEE. This new LEE will replace a failed unit astronauts removed during a series of spacewalks in the fall of 2017. Each end of the Canadarm2 robotic arm has an identical LEE, and they are used as the “hands” that grapple payloads and visiting cargo spaceships.
