Engineers at NASA's Jet Propulsion Laboratory in Southern California integrate the magnetometer instrument into the agency's Psyche spacecraft on June 28, 2021. Psyche, set to launch in August 2022, will investigate a metal-rich asteroid of the same name, which lies in the main asteroid belt between Mars and Jupiter. Scientists believe the asteroid could be part or all of the iron-rich interior of an early planetary building block that was stripped of its outer rocky shell as it repeatedly collided with other large bodies during the early formation of the solar system. Scientists know that the asteroid doesn't generate a magnetic field the way Earth does; but if Psyche had a magnetic field in the past, that magnetic field could still be recorded in Psyche's material today. With sensors mounted onto a 6-foot (2-meter) boom, the magnetometer can determine if Psyche is still magnetized. If so, that would confirm that the asteroid is part of the core of a planetesimal, the building block of an early planet. This photo shows one of the magnetometer's sensors. https://photojournal.jpl.nasa.gov/catalog/PIA24893

A test model of the boom that will be used for the magnetometer aboard NASA's Europa Clipper spacecraft is readied in NASA's Jet Propulsion Laboratory in Southern California. Called a dynamic test model, it is an exact duplicate of the Europa Clipper Magnetometer (ECM) boom that will fly on Europa Clipper. To fit aboard the rocket, the boom will be stowed in a canister and will deploy to its full length of 25 feet (8.5 meters) in the days after launch. The ECM will allow scientists to measure Europa's magnetic field and to measure the salinity and depth of Europa's internal global ocean. NASA scientists believe Jupiter's moon Europa may have the potential to harbor existing life, because of the internal ocean. Europa Clipper will swoop around Jupiter on an elliptical path, dipping close to the moon on each flyby. Understanding Europa's habitability will help scientists better understand how life developed on Earth and the potential for finding life beyond our planet. Europa Clipper is set to launch in 2024. https://photojournal.jpl.nasa.gov/catalog/PIA24786

STS061-23-005 (8 Dec 1993) --- Three members of the STS-61 crew prepare covers to be placed on magnetometers near the top of the Hubble Space Telescope (HST). Left to right are Richard O. Covey, mission commander; Kenneth D. Bowersox, pilot and Claude Nicollier, mission specialist. On the following day, astronauts Jeffrey A. Hoffman and F.

S70-56721 (December 1970) --- A close-up view of the Lunar Portable Magnetometer (LPM), which will be used by the crew of the Apollo 14 lunar landing mission during the second extravehicular activity (EVA). The LPM's components, a tripod-mounted flux-gate magnetometer sensor head and an electronics data package, connected by a 50-feet flat cable, function together to measure variations in the lunar magnetic field at several points on the geological traverse. Data gathered will be used to determine the location, strength and dimensions of magnetic sources, as well as knowledge of the local and total selenological structure. The LPM will be carried on the Modular Equipment Transporter (MET), and deployed by the lunar module pilot, who will align the sensor head at least 35 feet from the data package. The LM pilot will then return to the MET and verbally relay the LPM readouts to Earth. Astronaut Edgar D. Mitchell is the lunar module pilot for the Apollo 14 lunar landing mission.

Astronaut Alan L. Bean, lunar module pilot, deploys the Lunar Surface Magnetometer (LSM) during the first Apollo 12 extravehicular activity on the Moon. The LSM is a component of the Apollo Lunar Surface Experiments Package (ALSEP). The Lunar Module can be seen in the left background.

Sitting on the lunar surface, this magnetometer provided new data on the Moon’s magnetic field. This was one of the instruments used during the Apollo 12 mission. The second manned lunar landing mission, Apollo 12 launched from launch pad 39-A at Kennedy Space Center in Florida on November 14, 1969 via a Saturn V launch vehicle. The Saturn V vehicle was developed by the Marshall Space Flight Center (MSFC) under the direction of Dr. Wernher von Braun. Aboard Apollo 12 was a crew of three astronauts: Alan L. Bean, pilot of the Lunar Module (LM), Intrepid; Richard Gordon, pilot of the Command Module (CM), Yankee Clipper; and Spacecraft Commander Charles Conrad. The LM, Intrepid, landed astronauts Conrad and Bean on the lunar surface in what’s known as the Ocean of Storms while astronaut Richard Gordon piloted the CM, Yankee Clipper, in a parking orbit around the Moon. Lunar soil activities included the deployment of the Apollo Lunar Surface Experiments Package (ALSEP), finding the unmanned Surveyor 3 that landed on the Moon on April 19, 1967, and collecting 75 pounds (34 kilograms) of rock samples. Apollo 12 safely returned to Earth on November 24, 1969.

NASA's Psyche spacecraft is shown in a clean room on Dec. 8, 2022, at Astrotech Space Operations Facility near the agency's Kennedy Space Center in Florida. The spacecraft was powered on and connected to ground support equipment, enabling engineers and technicians to prepare it for launch in 2023. Teams working at Astrotech and at NASA's Jet Propulsion Laboratory in Southern California continue to monitor the health of its systems. After a one-year delay to complete critical testing, the Psyche project is targeting an October 2023 launch on a SpaceX Falcon Heavy rocket. NASA's Deep Space Optical Communications (DSOC) technology demonstration, testing high-data-rate laser communications, is integrated into Psyche and will travel with it when it launches to its target, a metal-rich asteroid, also named Psyche, that lies in the main asteroid belt. The silver-colored cylinder shown in the photo is the sunshade for DSOC, and the gold blanketing is the aperture cover for the DSOC payload. The spacecraft's target may be the partial core of a planetesimal, a building block of rocky planets in our solar system. Researchers will study Psyche using a suite of instruments including multispectral cameras, a Gamma Ray and Neutron Spectrometer (GRNS) and a magnetometer. The GRNS and magnetometer sensors are visible in the photo as the tips of the two black protrusions at the far end of the spacecraft. Also visible is the large, disc-shaped high-gain antenna, which will enable the spacecraft to communicate with Earth. https://photojournal.jpl.nasa.gov/catalog/PIA25664

S71-2250X (June 1971) --- A close-up view of the Scientific Instrument Module (SIM) to be flown for the first time on the Apollo 15 lunar landing mission. Mounted in a previously vacant sector of the Apollo Service Module (SM), the SIM carries specialized cameras and instrumentation for gathering lunar orbit scientific data. SIM equipment includes a laser altimeter for accurate measurement of height above the lunar surface; a large-format panoramic camera for mapping, correlated with a metric camera and the laser altimeter for surface mapping; a gamma ray spectrometer on a 25-feet extendible boom; a mass spectrometer on a 21-feet extendible boom; X-ray and alpha particle spectrometers; and a subsatellite which will be injected into lunar orbit carrying a particle and magnetometer, and the S-Band transponder.

This artist's concept depicts the 140-mile-wide (226-kilometer-wide) asteroid Psyche, which lies in the main asteroid belt between Mars and Jupiter. Psyche is the focal point of NASA's mission of the same name. The Psyche spacecraft is set to launch in August 2022 and arrive at the asteroid in 2026, where it will orbit for 21 months and investigate its composition. Scientists think that Psyche, unlike most other asteroids that are rocky or icy bodies, is made up of mostly iron and nickel — similar to the Earth's core. Exploring the asteroid could give valuable insight into how our own planet and others formed. The Psyche team will use a magnetometer to measure the asteroid's magnetic field. A multispectral imager will capture images of the surface, as well as data about the Psyche's composition and topography. Spectrometers will analyze the neutrons and gamma rays coming from the surface to reveal the elements that make up the asteroid itself. https://photojournal.jpl.nasa.gov/catalog/PIA23876

S61-E-017 (6 Dec 1993) --- Astronaut F. Story Musgrave uses one of the handrails on the Hubble Space Telescope (HST) during the second of his three sessions of STS-61 extravehicular activity (EVA-3). Astronauts Musgrave and Jeffrey A. Hoffman used this particular EVA to change out the Wide Field/Planetary Camera (WF/PC) and two magnetometers (also known as magnetic sensing systems). The photo was recorded with the Electronic Still Camera (ESC) inside Endeavour's cabin. Electronic still photography is a relatively new technology which provides the means for a handheld camera to electronically capture and digitize an image with resolution approaching film quality. The electronic still camera has flown as an experiment on several other shuttle missions.

This artist's concept shows NASA's InSight lander with its instruments deployed on the Martian surface. InSight's package of weather sensors, called the Auxiliary Payload Subsystem (APSS), includes an air pressure sensor inside the lander -- its inlet is visible on InSight's deck -- and two air temperature and wind sensors on the deck. Under the deck's edge is a magnetometer, provided by UCLA, to measure changes in the local magnetic field that could also influence SEIS. InSight's air temperature and wind sensors are actually refurbished spares built for Curiosity's Rover Environmental Monitoring Station (REMS). Called Temperature and Wind for InSight, or TWINS, these two east- and west-facing booms sit on the lander's deck and were provided by Spain's Centro de Astrobiología (CAB). https://photojournal.jpl.nasa.gov/catalog/PIA22957

This diagram depicts conditions observed by NASA's Cassini spacecraft during a flyby in Dec. 2013, when Saturn's magnetosphere was highly compressed, exposing Titan to the full force of the solar wind. In analyzing data from the encounter, scientists with Cassini's magnetometer team observed that the giant moon interacted with the solar wind much like the planets Mars and Venus, or a comet -- none of which possess their own internal magnetic field. Specifically, they saw that the solar wind draped itself around Titan, creating a shockwave that formed around Titan where the full-force solar wind rammed into the moon's atmosphere. Previously, researchers had thought Titan would have a different sort of interaction with the solar wind because of the moon's complex atmospheric chemistry. http://photojournal.jpl.nasa.gov/catalog/PIA19055

NASA's Psyche spacecraft is captured here on August 18, 2021, in a clean room at the agency's Jet Propulsion Laboratory in Southern California – in the midst of system integration and test. The mission's launch period opens August 1, 2022. The nitrogen tanks are visible in the center of the spacecraft chassis, encased in red protective "remove before flight" covers. Mounted on the right is the strut tower, which will host the sensors for two of the science instruments – the magnetometer and the Gamma Ray and Neutron Spectrometer (GRNS). By spring of 2022, the fully assembled Psyche spacecraft will ship from JPL to NASA's Kennedy Space Center for launch. In early 2026, the spacecraft will arrive at its target, an asteroid of the same name in the main asteroid belt between Mars and Jupiter. Scientists believe asteroid Psyche, which is about 140 miles (226 kilometers) wide, is made largely of iron and nickel and could be the core of an early planet. The spacecraft will spend 21 months orbiting the asteroid and gathering science data. Besides the magnetometer and the GRNS, Psyche will carry a multispectral imager. The mission also will test a sophisticated new laser communications technology, recently completed by JPL, called Deep Space Optical Communications (DSOC). The technology demonstration will focus on using lasers to enhance communications speeds and prepare for data-intensive transmissions, which could potentially include livestream videos for future missions. Arizona State University leads the mission. JPL is responsible for the mission's overall management, system engineering, integration and testing, and mission operations. Maxar Technologies is providing a high-power solar electric propulsion spacecraft chassis. Psyche is the 14th mission selected as part of NASA's Discovery Program. https://photojournal.jpl.nasa.gov/catalog/PIA24787
