    SAN ANTONIO — Jan. 5, 2023 — A groundbreaking new mass spectrometer designed and constructed by Southwest Analysis Institute (SwRI) has been delivered for integration onto NASA’s Europa Clipper spacecraft. Scheduled to launch in 2024 and arrive within the Jovian system by 2030, Europa Clipper will conduct an in depth science investigation of the moon Europa and research whether or not it may harbor situations appropriate for all times.

    The MAss Spectrometer for Planetary EXploration (MASPEX) instrument will probably be one in all 9 science devices within the mission payload, which additionally contains Europa-UVS, an SwRI-developed Ultraviolet Spectrograph, the newest in a sequence of spacecraft devices. MASPEX will analyze the gases close to Europa to grasp the chemistry of Europa’s floor, ambiance and suspected subsurface ocean. MASPEX will research how Jupiter’s radiation alters Europa’s floor compounds and the way its icy floor and subsurface ocean alternate materials.

    “MASPEX has a mass decision a whole lot of instances finer than something that has flown to house earlier than,” stated SwRI Senior Vice President Jim Burch, who serves as MASPEX principal investigator. Burch leads the Institute’s House Sector, with three divisions dedicated to house science, photo voltaic system science and house programs. “SwRI has used inner funding and NASA assets to develop an instrument capable of differentiate between molecules with nearly equivalent plenty based mostly on the vitality binding the atoms. It additionally differentiates isotopes — atoms with equal numbers of protons however a special variety of neutrons. These capabilities are important to revealing the secrets and techniques of Europa.”

    As soon as it arrives, Europa Clipper will orbit Jupiter and carry out repeated shut flybys of the icy moon. MASPEX works by taking in fuel molecules lofted from the floor of Europa and changing them into charged particles referred to as ions. It bounces the ions (atoms and molecules lacking an electron) as much as 400 instances backwards and forwards throughout the instrument. By timing their transit by means of the instrument, MASPEX measures the mass of those ions, which reveals every molecule’s identification, which in flip helps decide whether or not Europa is liveable.

    “It has been an enormous group effort to get this next-generation house mass spectrometer constructed, examined and delivered,” stated Steve Persyn, mission supervisor for MASPEX and a program director in SwRI’s House Methods Division. “SwRI has many years of expertise designing and constructing devices for house missions.”

    SwRI-developed devices embrace a number of of these onboard NASA’s New Horizons spacecraft to Pluto and the Kuiper Belt, the Lunar Reconnaissance Orbiter (LRO), the Juno spacecraft now orbiting Jupiter, and ESA’s JUpiter ICy Moons Explorer (JUICE) deliberate for a 2023 launch to orbit each Jupiter and its moon Ganymede.

    “We hope to establish and fly by means of plumes and different sources of fuel venting from cracks in Europa’s icy floor,” stated SwRI’s Dr. Christopher Glein, MASPEX co-investigator and a planetary geochemist. “We all know microbes on Earth exploit any molecule that may function a meals supply. MASPEX goes to assist Europa Clipper decide whether or not there’s something for microbes to eat, equivalent to natural molecules that could be sourced from hydrothermal vents on the backside of a deep ocean. The information from this thrilling mission will give us a a lot richer perspective on the habitability of Europa.”

    NASA’s Jet Propulsion Laboratory (JPL) manages the Europa Clipper mission for NASA’s Science Mission Directorate in Washington, D.C. The Europa Clipper mission is being developed in partnership with the Johns Hopkins College Utilized Physics Laboratory (APL), Laurel, Maryland.
