NASA’s MEGANE, developed for the MMX mission to review Mars’ moons, has been delivered to JAXA for integration, representing a milestone in house collaboration and scientific exploration.
On March 14, NASA delivered its gamma-ray and neutron spectrometer instrument to JAXA (Japan Aerospace Exploration Company) for integration onto JAXA’s MMX (Martian Moons eXploration) mission spacecraft and last system-level testing.
NASA’s Mars-moon Exploration with Gamma Ray and Neutrons (MEGANE) instrument, developed by the Johns Hopkins Utilized Physics Laboratory (APL) in Laurel, Maryland, in collaboration with colleagues from Lawrence Livermore Nationwide Laboratory (LLNL) in California, will play a serious function within the MMX mission, which goals to characterize and decide the origin of Mars’ moons Phobos and Deimos and ship a pattern from Phobos to Earth.

Scientific Objectives and Instrument Capabilities
Scientists suspect the asteroid-sized our bodies both are remnants of an historic collision between Mars and a big impactor or are themselves asteroids captured by Mars’ gravity. By measuring the energies of neutrons and gamma rays emitted from the floor of Phobos, MEGANE will let MMX “see” the fundamental composition of the moon’s floor and assist peg the doubtless origin of the moon.
“MEGANE can be a key instrument on MMX, making a giant contribution towards the aim of understanding the origin of the Martian moons,” stated Thomas Statler, MEGANE program scientist at NASA Headquarters in Washington. “NASA is glad to see MEGANE prepared for integration, one other step in NASA’s persevering with collaboration with JAXA on this groundbreaking mission.”
Instrument Growth and Future Missions
The instrument staff acquired the inexperienced gentle final fall to ship MEGANE (pronounced meh-GAH-nay, the Japanese phrase for “eyeglasses”) after the venture’s standing assessment board evaluated the system’s readiness. That milestone marked the tip of a demanding 6-year design and improvement course of, which met NASA’s value and schedule constraints.
“Passing the pre-ship assessment and delivering the {hardware} are vital steps for all these engaged on MEGANE,” stated APL’s David Lawrence, the instrument’s principal investigator. “Like all spaceflight builds, we have now had challenges getting thus far, however we’re excited to see how MEGANE works with all the opposite spacecraft elements for this thrilling MMX mission.”
With MEGANE now in Japan, the MMX staff will start integrating the scientific devices, together with MEGANE, with different spacecraft elements, earlier than placing all the system by way of a collection of assessments in preparation for launch, which is scheduled for fiscal yr 2026, aboard a JAXA H3 rocket.
“For me personally, I’m wanting ahead to all the combination and take a look at operations which can be to return,” stated Sarah Bucior, an area techniques engineer in SES and the MEGANE I&T Lead Engineer. “I really like rockets, so I’m actually to see how they construct their spacecraft after which observe it alongside to launch operations and liftoff.”
MEGANE was developed below NASA’s Discovery Program, which offers low-cost entry to house. The Discovery Program is managed by NASA’s Marshall House Flight Heart in Huntsville, Alabama for the Science Mission Directorate at NASA Headquarters in Washington. The instrument science staff contains investigators from APL, LLNL, Marietta Faculty, NASA’s Ames Analysis Heart in California’s Silicon Valley, and JAXA.
