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.

With an internal global ocean under a thick layer of ice, Jupiter's moon Europa may have the potential to harbor existing life. Europa Clipper will swoop around Jupiter in an elliptical orbit, dipping close to the moon on each flyby to collect data. Understanding Europa's habitability will help scientists better understand how life developed on Earth and the potential for finding life beyond our planet.

Inside the Payload Hazardous Servicing Facility at NASA's Kennedy Space Center in Florida, members of the news media get a close-up view of a Cygnus cargo vessel. The spacecraft is scheduled for the upcoming Orbital ATK Commercial Resupply Services-6 mission to deliver hardware and supplies to the International Space Station. Reporters, 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.

Technicians transfer the Sentinel-6B spacecraft from the NASA hangar to the Astrotech Space Operations payload processing facility at Vandenberg Space Force Base in California on Thursday, Sept. 25, 2025. Sentinel-6B will undergo detailed inspections, tests, and fueling in a cleanroom as it prepares for a November launch on a SpaceX Falcon 9 rocket. The spacecraft is designed to measure sea levels down to roughly an inch for about 90% of the world’s oceans. Sentinel-6B also will extend the record of atmospheric temperatures, begun by Sentinel-6 Michael Freilich, out to a decade.

MMS Spacecraft Animation The Magnetospheric Multiscale (MMS) mission is a Solar Terrestrial Probes mission comprising four identically instrumented spacecraft that will use Earth's magnetosphere as a laboratory to study the microphysics of three fundamental plasma processes: magnetic reconnection, energetic particle acceleration, and turbulence. These processes occur in all astrophysical plasma systems but can be studied in situ only in our solar system and most efficiently only in Earth's magnetosphere, where they control the dynamics of the geospace environment and play an important role in the processes known as "space weather."

NASA’s PACE (Plankton, Aerosol, Cloud, ocean Ecosystem) spacecraft is pictured during pre-launch processing on Wednesday, Jan. 3, 2024, inside a cleanroom at the Astrotech Space Operations Facility near the agency’s Kennedy Space Center in Florida. NASA invited members of the media to speak with mission subject matter experts and view the spacecraft before it is encapsulated into its payload fairing for its launch aboard a SpaceX Falcon 9 rocket no earlier than Tuesday, Feb. 6, 2024, from Space Launch Complex 40 at Cape Canaveral Space Force Station in Florida.

The Ocean Color Instrument (OCI) is configured for vibration testing. OCI is bagged with Dun-Shield to protect the instrument from contamination outside of a cleanroom environment, and also provides protection from static electricity. 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 (Plankton, Aerosol, Cloud, ocean Ecosystem) primary sensor built at Goddard Space Flight Center in Greenbelt, MD.
