Flight hardware for NASA’s Orbital Syngas Commodity Augmentation Reactor, or OSCAR, is inside the Applied Physics Lab inside the Neil Armstrong Operations and Checkout Facility at the agency’s Kennedy Space Center in Florida on July 21, 2022. OSCAR began as an Early Career Initiative project at the spaceport that studies technology to convert trash and human waste into useful gasses such as methane, hydrogen, and carbon dioxide. By processing small pieces of trash in a high-temperature reactor, OSCAR is advancing new and innovative technology for managing waste in space.

Nurge recently completed optical metrology testing and evaluation of all flight windows on the Orion capsule for Artemis 1. The interferometer uses a laser source to do wavefront and transmission measurements, as well as evaluation of the color balance. Artemis 1 is an uncrewed flight that will pave the way for future crewed missions and enable future missions to the Moon, Mars, and beyond.

CAPE CANAVERAL, Fla. – Students and their teachers get some hands-on experience inside the applied physics lab in the Operations and Checkout Building. The 26 honor students in chemistry and biology and their teachers got a chance to visit a number of high-tech labs at Kennedy Space Center as part of an effort to encourage students in the areas of science, technology, engineering and math. The tenth and eleventh grade students from Terry Parker High School in Jacksonville, Fla., visited a number of vastly different labs during their one-day tour. The group's visit to Kennedy was hosted by the Education Office as part of a nationwide effort by the National Lab Network to help introduce the nation's students to science careers.

KENNEDY SPACE CENTER, FLA. - At their consoles in the Atlas V Spaceflight Operations Center on Cape Canaveral Air Force Station, members of the New Horizons team take part in a dress rehearsal for the launch scheduled in mid-January. Seen here (left to right) are David Kusnierkiewicz, New Horizons mission system engineer; Glen Fountain, Applied Physics Lab project manager; and Alan Stern, principal investigator from Southwest Research Institute. New Horizons carries seven scientific instruments that will characterize the global geology and geomorphology of Pluto and its moon Charon, map their surface compositions and temperatures, and examine Pluto's complex atmosphere. After that, flybys of Kuiper Belt objects from even farther in the solar system may be undertaken in an extended mission. New Horizons is the first mission in NASA's New Frontiers program of medium-class planetary missions. The spacecraft, designed for NASA by the Johns Hopkins University Applied Physics Laboratory in Laurel, Md., will launch aboard a Lockheed Martin Atlas V rocket and fly by Pluto and Charon as early as summer 2015.

Principal investigator, Dr. Janine Captain, attaches a mass spectrometer sensor to electronics inside a vacuum chamber in the Space Station Processing Facility high bay at NASA’s Kennedy Space Center on Dec. 12, 2018. The Mass Spectrometer observing lunar operations (MSolo) instrument is a commercial off-the-shelf mass instrument modified to work in space, and can identify molecules at lunar landing sites. These MSolo instruments are part of NASA’s efforts to return to the Moon with the Commercial Lunar Payload Services Landers Program.

Principal investigator, Dr. Janine Captain, demonstrates the effects of moving a magnet against metal in the Applied Physics Laboratory at NASA’s Kennedy Space Center on Dec. 12, 2018. When dropped or tipped over on a plate of copper, the magnet decelerates and slowly touches down on the plate visually demonstrating the physics of the magnetic field.

KENNEDY SPACE CENTER, FLA. -- NASA's Comet Nucleus Tour (CONTOUR) spacecraft successfully launches at 2:47 a.m. EDT aboard a Boeing Delta II rocket from Cape Canaveral Air Force Station, Fla. Designed and built by The Johns Hopkins University Applied Physics Laboratory (APL) in Laurel, Md., the 2,138-pound (970-kilogram) spacecraft was placed into an elliptical Earth orbit 63 minutes after launch. About 19 minutes later the mission operations team at APL acquired a signal from the spacecraft through the Deep Space Network antenna station in Goldstone, Calif., and by 5:45 a.m. EDT Mission Director Dr. Robert W. Farquhar of the Applied Physics Lab confirmed the craft was operating normally and ready to carry out its early orbit maneuvers. CONTOUR will orbit Earth until Aug. 15, when it is scheduled to fire its main engine and enter a comet-chasing orbit around the sun. The mission's flexible four-year plan includes encounters with comets Encke (Nov. 12, 2003) and Schwassmann-Wachmann 3 (June 19, 2006), though it can add an encounter with a "new" and scientifically valuable comet from the outer solar system, should one be discovered in time for CONTOUR to fly past it. CONTOUR's four scientific instruments will take detailed pictures and measure the chemical makeup of each comet's nucleus -- a chunk of ice and rock -- while analyzing the surrounding gas and dust.

Technicians test the spring-activated door on the Interstellar Dust Experiment (IDEX) instrument of NASA’s IMAP (Interstellar Mapping and Acceleration Probe) observatory inside the high bay at the Astrotech Space Operations Facility near the agency’s Kennedy Space Center in Florida on Tuesday, June 3, 2025. The door will remain closed to protect IDEX from contamination during integration and launch. Once in space, the door will swing open permanently to allow interstellar and interplanetary dust to flow into the instrument for measurement. The IMAP observatory will study how the Sun shapes the boundaries of the heliosphere, the protective bubble around our solar system. Launch is targeted for no earlier than September 2025 aboard a SpaceX Falcon 9 rocket from Launch Complex 39A at NASA Kennedy.

Technicians test the spring-activated door on the Interstellar Dust Experiment (IDEX) instrument of NASA’s IMAP (Interstellar Mapping and Acceleration Probe) observatory inside the high bay at the Astrotech Space Operations Facility near the agency’s Kennedy Space Center in Florida on Tuesday, June 3, 2025. The door will remain closed to protect IDEX from contamination during integration and launch. Once in space, the door will swing open permanently to allow interstellar and interplanetary dust to flow into the instrument for measurement. The IMAP observatory will study how the Sun shapes the boundaries of the heliosphere, the protective bubble around our solar system. Launch is targeted for no earlier than September 2025 aboard a SpaceX Falcon 9 rocket from Launch Complex 39A at NASA Kennedy.

Included in the payload of science instruments for NASA's Europa Clipper is the Plasma Instrument for Magnetic Sounding (PIMS). Scientists will use PIMS to study the characteristics of plasma around Europa to better understand the moon's ice-shell thickness, ocean depth, and ocean salinity. PIMS will have four sensors, called Faraday cups, to measure the electrical current produced by charged particles (or plasma) as they strike a detector plate inside each sensor. In this photo, the Plasma Instrument Calibration Chamber at the Johns Hopkins Applied Physics Laboratory (APL) in Laurel, Maryland, recreates the plasma environments that PIMS and other instruments will encounter in space. The equipment in this lab simulates these environments with ion beams that reproduce plasma energy ranges found at Jupiter and Europa. Once PIMS is fully assembled in the clean room attached to the chamber, the team will direct these ion and electron beams into the Faraday cup sensors for calibration. This will be used specifically to simulate the plasma in Europa's ionosphere and Jupiter's magnetosphere, which PIMS will later measure directly. With an internal global ocean twice the size of Earth's oceans combined, Europa may have the potential to harbor life. NASA's Europa Clipper spacecraft will swoop around Jupiter on an elliptical path, 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. https://photojournal.jpl.nasa.gov/catalog/PIA24330
