The Northrop Grumman Pegasus XL rocket containing NASA's Ionospheric Connection Explorer (ICON) is seen outside the cleanroom after assembly at Vandenberg Air Force Base in California on Sept 19, 2019. ICON launched on the Pegasus XL rocket, attached beneath the company's L-1011 Stargazer aircraft, on Oct. 10, 2019, after takeoff from the Skid Strip at Cape Canaveral Air Force Station in Florida. ICON will study the frontier of space - the dynamic zone high in Earth's atmosphere where terrestrial weather from below meets space weather above. The explorer will help determine the physics of Earth's space environment and pave the way for mitigating its effects on our technology, communications systems and society.

The Ocean Color Instrument (OCI) team transports the instrument on its dolly to a cleanroom at Goddard Space Flight Center for final operations prior to integration to the Plankton, Aerosol, Cloud, ocean Ecosystem (PACE) spacecraft. OCI is a highly advanced optical spectrometer that will be used to measure properties of light over portions of the electromagnetic spectrum. It will enable continuous measurement of light at finer wavelength resolution than previous NASA satellite sensors, extending key system ocean color data records for climate studies. OCI is PACE's primary sensor built at Goddard Space Flight Center in Greenbelt, MD.

NASA Administrator Charles Bolden listens to Magnetospheric Multiscale (MMS) Mission Project Manager Craig Tooley talk about the MMS mission outside of a Naval Research Laboratory cleanroom where one of four Magnetospheric Multiscale (MMS) spacecraft is currently undergoing testing, Monday, August 4, 2014, in Washington. The Magnetospheric Multiscale, or MMS, mission will study the mystery of how magnetic fields around Earth connect and disconnect, explosively releasing energy via a process known as magnetic reconnection. The four identical spacecraft are scheduled to launch in 2015 from Cape Canaveral and will orbit around Earth in varying formations through the dynamic magnetic system surrounding our planet to provide the first three-dimensional views of the magnetic reconnection process. The goal of the STP Program is to understand the fundamental physical processes of the space environment from the sun to Earth, other planets, and the extremes of the solar system boundary.

A number of Kennedy employees presented their proposals as part of the Chief Technologist Innovation Call. The event sought out ideas based on relevance, benefit, innovativeness, likelihood of success and sustainability.

NASA’s Psyche spacecraft is made available to media for viewing inside a cleanroom at the Astrotech Space Operations Facility near Kennedy Space Center in Florida on Aug. 11, 2023. Psyche will launch atop a SpaceX Falcon Heavy rocket from Launch Complex 39A at Kennedy to explore a metal-rich asteroid. Launch is targeted for Oct. 5, 2023. Riding with Psyche is a pioneering technology demonstration, NASA’s Deep Space Optical Communications (DSOC) experiment.

Inside the Payload Hazardous Servicing Facility at NASA's Kennedy Space Center in Florida, a Cygnus cargo spacecraft is being prepared for the upcoming Orbital ATK Commercial Resupply Services-6 mission to deliver hardware and supplies to the International Space Station. Technicians and engineers are clad in "bunny suits." The cleanroom garments are worn to prevent contamination in the controlled environment. The Cygnus is scheduled to lift off atop a United Launch Alliance Atlas V rocket on March 22.

S89-25281 (8 Oct 1988) --- The Magellan spacecraft is hoisted from the transport trailer of the Payload Environmental Transportation System (PETS) to the floor of the cleanroom in the SAEF-2 planetary checkout facility at the Kennedy Space Center (KSC). The spacecraft, destined for unprecedented studies of Venusian topographic features, is to be deployed by the crew of NASA's STS-30 mission in April 1989.
