A SpaceX Falcon 9 rocket soars upward after lifting off from Space Launch Complex 40 at Cape Canaveral Air Force Station in Florida, carrying NASA's Transiting Exoplanet Survey Satellite (TESS). Liftoff was at 6:51 p.m. EDT. 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.

STS130-S-031 (8 Feb. 2010) --- Against a black night sky, space shuttle Endeavour and its six-member STS-130 crew head toward Earth orbit and rendezvous with the International Space Station. Liftoff was at 4:14 a.m. (EST) on Feb. 8, 2010 from launch pad 39A at NASA's Kennedy Space Center. Onboard are NASA astronauts George Zamka, commander; Terry Virts, pilot; Robert Behnken, Kathryn Hire, Nicholas Patrick and Stephen Robinson, all mission specialists. This was the second launch attempt for Endeavour's STS-130 crew and the final scheduled space shuttle night launch. The first attempt on Feb. 7 was scrubbed due to unfavorable weather. The primary payload for the STS-130 mission to the International Space Station is the Tranquility node, a pressurized module that will provide additional room for crew members and many of the station's life support and environmental control systems. Attached to one end of Tranquility is the Cupola module, a unique work area with six windows on its sides and one on top. The Cupola resembles a circular bay window and will provide a vastly improved view of the station's exterior. The multi-directional view will allow the crew to monitor spacewalks and docking operations, as well as provide a spectacular view of Earth and other celestial objects. The module was built in Turin, Italy, by Thales Alenia Space for the European Space Agency.

The first stage of a two-stage SpaceX Falcon 9 rocket makes its descent toward Landing Zone 1 at Cape Canaveral Space Force Station after lifting off from NASA Kennedy Space Center’s Launch Complex 39A in Florida for the Axiom Mission 2 (Ax-2) on May 21, 2023. Ax-2 is the second all private astronaut mission to the International Space Station, sending Commander Peggy Whitson, Pilot John Shoffner, and Mission Specialists Ali Alqarni and Rayyanah Barnawi to the orbiting laboratory, where they will spend about 10 days conducting scientific research, outreach, and commercial activities. Liftoff occurred at 5:37 p.m. EDT.

STS-32 Columbia, Orbiter Vehicle (OV) 102, atop the external tank (ET) and flanked by two solid rocket boosters (SRBs) rises above the mobile launcher platform and is nearly clear of the fixed service structure (FSS) tower at Kennedy Space Center (KSC) Launch Complex (LC) Pad 39A. Plumes of smoke billow from the SRBs and cover the launch pad in a cloud. Liftoff occurred at 7:34:59:98 am Eastern Standard Time (EST) some 24 hours after dubious weather at the return-to-landing site (RTLS) had cancelled a scheduled launch. OV-102's launch is highlighted against the early morning darkness.

S71-17620 (31 Jan. 1971) --- The huge, 363-feet tall Apollo 14 (Spacecraft 110/Lunar Module 8/Saturn 509) space vehicle is launched from Pad A, Launch Complex 39, Kennedy Space Center, Florida, at 4:03:02 p.m. (EST), Jan. 31, 1981, on a lunar landing mission. This view of the liftoff was taken by a camera mounted on the mobile launch tower. Aboard the Apollo 14 spacecraft were astronauts Alan B. Shepard Jr., commander; Stuart A. Roosa, command module pilot; and Edgar D. Mitchell, lunar module pilot.

S68-27364 (4 April 1968) --- The Apollo 6 (Spacecraft 020/Saturn 502) unmanned space mission was launched from Pad A, Launch Complex 39, Kennedy Space Center (KSC), Florida. The liftoff of the huge Apollo/Saturn V space vehicle occurred at 7:00:01.5 a.m. (EST), April 4, 1968.

STS-34 Atlantis, Orbiter Vehicle (OV) 104, lifts off from Kennedy Space Center (KSC) Launch Complex (LC) Pad 39B at 12:53:39:983 pm Eastern Daylight Time (EDT). This aerial view shows OV-104, its external tank (ET), and two solid rocket boosters (SRBs) rising high above LC Pad 39B atop a plume of exhaust smoke. Atlantic Ocean is visible in the background. The liftoff marks the beginning of a five-day mission in space.

Air-to-air view, taken from the weather-monitoring Shuttle Training Aircraft (STA), shows STS-42 Discovery, Orbiter Vehicle (OV) 103, as it soars above the Atlantic Ocean after liftoff from a Kennedy Space Center (KSC) Launch Complex (LC) Pad at 9:52:33 am (Eastern Standard Time (EST)). The exhaust plume traces OV-103's flight path.

STS075-S-007 (22 Feb. 1996) --- A remote camera at Launch Pad 39B, at the Kennedy Space Center (KSC), recorded this profile view of the space shuttle Columbia as it cleared the tower to begin the mission. The liftoff occurred on schedule at 3:18:00 p.m. (EST), Feb. 22, 1996. Onboard Columbia for the scheduled two-week mission were astronauts Andrew M. Allen, commander; Scott J. Horowitz, pilot; Franklin R. Chang-Diaz, payload commander; and astronauts Maurizio Cheli, Jeffrey A. Hoffman and Claude Nicollier, along with payload specialist Umberto Guidoni. Cheli and Nicollier represent the European Space Agency (ESA), while Guidoni represents the Italian Space Agency (ASI).

STS-31 Discovery, Orbiter Vehicle (OV) 103, is hidden in low-lying cloud cover as it rises above Kennedy Space Center (KSC) Launch Complex (LC) Pad 39B just after its liftoff at 8:33:51.0492 am (Eastern Daylight Time (EDT)). The glow of the solid rocket booster (SRB) and the space shuttle main engine (SSME) firings appears just below the cloud cover and is reflected in the nearby waterway (foreground). An exhaust plume trails from OV-103 and its SRBs and covers the launch pad area.

STS-41 Discovery, Orbiter Vehicle (OV) 103, lifts off from the Kennedy Space Center (KSC) Launch Complex (LC) Pad 39 mobile launcher platform at 7:47 am (Eastern Daylight Time (EDT)). OV-103 riding atop the external tank (ET) and flanked by two solid rocket boosters (SRBs), is captured just moments after liftoff. Not yet clear of the fixed service structure (FSS) tower, OV-103 is highlighted against the cloudless morning sky. Exhaust smoke billows from the SRBs and the space shuttle main engines (SSMEs) creating a cloud over the launch pad area.

Columbia, Orbiter Vehicle (OV) 102, heads skyward after clearing the fixed service structure (FSS) tower at Kennedy Space Center (KSC) Launch Complex (LC) Pad 39A. Florida plant life appears in the foreground. The exhaust cloud produced by OV-102's solid rocket boosters (SRBs) covers the launch pad area with the exception of the sound suppression water system tower. OV-102's starboard side and the right SRB are visible from this angle. Launch occurred at 12:43 pm Eastern Daylight Time (EDT). Once in Earth orbit, STS-65's six NASA astronauts and a Japanese Payload Specialist aboard OV-102 will begin two weeks of experimentation in support of the second International Microgravity Laboratory (IML-2).

STS-31 Discovery, Orbiter Vehicle (OV) 103, rides above the firey glow of the solid rocket boosters (SRBs) and space shuttle main engines (SSMEs) and a long trail of exhaust as it heads toward Earth orbit. Kennedy Space Center (KSC) Launch Complex (LC) Pad 39B is covered in an exhaust cloud moments after the liftoff of OV-103 at 8:33:51.0492 am (Eastern Daylight Time (EDT)). The exhaust plume pierces the low-lying clouds as OV-103 soars into the clear skies above. A nearby waterway appears in the foreground.

In this distant view, STS-31 Discovery, Orbiter Vehicle (OV) 103, is seen as it heads skyward after liftoff from Kennedy Space Center (KSC) Launch Complex (LC) Pad 39B at 8:33:51.0492 am (Eastern Daylight Time (EDT)). OV-103's silhouette atop the external tank (ET) appears above the glow of the solid rocket booster (SRB) and space shuttle main engine (SSME) firings. An exhaust plume trails behind and covers the launch pad area below the orbiter. A nearby waterway reflects the SRB/SSME glow in the foreground. At the far right and barely discernible is KSC LC Pad 39A and the Sound Supression Water System tower. Columbia, OV-102, is on LC Pad 39A which is separated by a distance of 1.6 miles. This was the first time since January 1986 that there was a shuttle on each pad.
