The SpaceX Falcon 9 rocket with the Dragon cargo module climbs upward after liftoff from Space Launch Complex 40 on Cape Canaveral Air Force Station in Florida in the early morning May 4, 2019. Liftoff was at 2:48 a.m. EDT. This is SpaceX’s 17th Commercial Resupply Services (CRS-17) mission for NASA to the International Space Station. The Dragon cargo module will deliver about 5,500 pounds of science and research, crew supplies and vehicle hardware to the orbital laboratory and its crew.

The two-stage Falcon 9 launch vehicle lifts off Space Launch Complex 40 at Cape Canaveral Air Force Station carrying the 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.

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.

The SpaceX Falcon 9 rocket is ready to roll out to Space Launch Complex 40 at Cape Canaveral Air Force Station in Florida, with NASA's Transiting Exoplanet Survey Satellite (TESS) secured in its payload fairing. TESS will launch on the Falcon 9 no earlier than 6:51 p.m. EDT on April 18. TESS will 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.
