KENNEDY SPACE CENTER, FLA. - A solid rocket booster (SRB) is lifted to vertical on Launch Complex 17-B, Cape Canaveral Air Force Station. The SRB will be attached to the Delta II Heavy rocket that will launch the Space Infrared Telescope Facility (SIRTF). The Delta II Heavy features nine 46-inch-diameter, stretched SRBs. Consisting of three cryogenically cooled science instruments and an 0.85-meter telescope, SIRTF is one of NASA's largest infrared telescopes to be launched. SIRTF will obtain images and spectra by detecting the infrared energy, or heat, radiated by objects in space. Most of this infrared radiation is blocked by the Earth's atmosphere and cannot be observed from the ground.

The SpaceX Falcon Heavy rocket’s two side cores separate from the center core as the vehicle performs its demonstration flight. The rocket lifted off at 3:45 p.m. EST from Launch Complex 39A at NASA's Kennedy Space Center in Florida. This is a significant milestone for the world's premier multi-user spaceport. In 2014, NASA signed a property agreement with SpaceX for the use and operation of the center's pad 39A, where the company has launched Falcon 9 rockets and prepared for the first Falcon Heavy. NASA also has Space Act Agreements in place with partners, such as SpaceX, to provide services needed to process and launch rockets and spacecraft.

At Cape Canaveral Air Force Station's Launch Complex 37, United Launch Alliance engineers and technicians prepare to lift the agency's Orion spacecraft for mounting atop its Delta IV Heavy rocket. Orion is the exploration spacecraft designed to carry astronauts to destinations not yet explored by humans, including an asteroid and Mars. It will have emergency abort capability, sustain the crew during space travel and provide safe re-entry from deep space return velocities. The first unpiloted flight test of Orion is scheduled to launch Dec. 4, 2014 atop a United Launch Alliance Delta IV Heavy rocket, and in 2018 on NASA’s Space Launch System rocket.

The first stage of a United Launch Alliance Delta IV Heavy rocket is prepared to be lifted vertical at the Vertical Integration Facility near Space Launch Complex 37 at Cape Canaveral Air Force Station in Florida. The Delta IV Heavy will launch NASA's upcoming Parker Solar Probe mission in July 2018. The mission will perform the closest-ever observations of a star when it travels through the Sun's atmosphere, called the corona. The probe will rely on measurements and imaging to revolutionize our understanding of the corona and the Sun-Earth connection.

Teams offload NASA’s largest planetary mission spacecraft, Europa Clipper, from a United States Air Force C-17 Globemaster III transport aircraft onto the flatbed of a heavy-lift truck at the Launch and Landing Facility at NASA’s Kennedy Space Center in Florida on Thursday, May 23, 2024. Crews transported Europa Clipper to the Payload Hazardous Servicing Facility at Kennedy to prepare it for launch aboard a SpaceX Falcon Heavy rocket later this year from Launch Complex 39A at the Florida spaceport. Europa Clipper will help determine if conditions exist below the surface Jupiter’s fourth largest moon, Europa, that could support life.

Scheduled to lift off Aug. 2, bound for Mercury, the spacecraft is expected to reach orbit around Mercury in March 2011. MESSENGER was built for NASA by the Johns Hopkins University Applied Physics Laboratory in Laurel, Md.

KENNEDY SPACE CENTER, FLA. - A second Solid Rocket Booster (SRB) for the MESSENGER spacecraft launch is raised from its transporter to lift up the mobile service tower at Pad 17-B, Cape Canaveral Air Force Station. The first SRB is seen at right. The SRBs will be mated to the Boeing Delta II Heavy rocket for the Aug. 2 launch to the planet Mercury.

CAPE CANAVERAL, Fla. -- At NASA's Kennedy Space Center in Florida, crawler-transporter No. 2 has been undergoing modifications in high bay 2 of the Vehicle Assembly Building. It has been undergoing a test drive checking out modifications to ensure its ability to carry the space agency's Space Launch System heavy-lift rocket to the launch pad. In the background is the mobile launcher being prepared to support launch vehicles such as space agency's the Space Launch System heavy-lift rocket and Orion spacecraft. NASA's Ground Systems Development and Operations Program is leading the 20-year life-extension project for the crawler. A pair of behemoth machines called crawler-transporters has carried the load of taking rockets and spacecraft to the launch pad for more than 40 years at NASA’s Kennedy Space Center in Florida. Each the size of a baseball infield and powered by locomotive and large electrical power generator engines, the crawler-transporters will stand ready to keep up the work for the next generation of launch vehicles projects to lift astronauts into space.

CAPE CANAVERAL, Fla. – At NASA's Kennedy Space Center in Florida, the agency's Orion spacecraft passes the spaceport's iconic Vehicle Assembly Building as it is transported to Launch Complex 37 at Cape Canaveral Air Force Station. After arrival at the launch pad, United Launch Alliance engineers and technicians will lift Orion and mount it atop its Delta IV Heavy rocket. Orion is the exploration spacecraft designed to carry astronauts to destinations not yet explored by humans, including an asteroid and Mars. It will have emergency abort capability, sustain the crew during space travel and provide safe re-entry from deep space return velocities. The first unpiloted flight test of Orion is scheduled to launch Dec. 4, 2014 atop a United Launch Alliance Delta IV Heavy rocket, and in 2018 on NASA’s Space Launch System rocket.
