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 circumstances appropriate for all times.
The MAss Spectrometer for Planetary EXploration (MASPEX) instrument can be one in all 9 science devices within the mission payload, which additionally consists of 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 trade materials.
“MASPEX has a mass decision lots of of instances finer than something that has flown to area earlier than,” mentioned SwRI Senior Vice President Jim Burch, who serves as MASPEX principal investigator. Burch leads the Institute’s Area Sector, with three divisions dedicated to area science, photo voltaic system science and area techniques.
“SwRI has used inner funding and NASA assets to develop an instrument capable of differentiate between molecules with nearly similar lots based mostly on the power binding the atoms. It additionally differentiates isotopes – atoms with equal numbers of protons however a special variety of neutrons. These capabilities are crucial 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 forwards and backwards throughout the instrument. By timing their transit by way 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 workforce effort to get this next-generation area mass spectrometer constructed, examined and delivered,” mentioned Steve Persyn, challenge supervisor for MASPEX and a program director in SwRI’s Area Methods Division. “SwRI has many years of expertise designing and constructing devices for area 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 way of plumes and different sources of fuel venting from cracks in Europa’s icy floor,” mentioned 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, reminiscent of natural molecules that is likely to be sourced from hydrothermal vents on the backside of a deep ocean. The info from this thrilling mission will give us a a lot richer perspective on the habitability of Europa.”

Mix a space juice to celebrate ESA’s Juice mission
Paris (ESA) Jan 03, 2023
ESA is kicking off the brand new 12 months by inviting you to create a novel juice mocktail to symbolize the JUpiter ICy moons Explorer – often known as Juice – launching in April. The winner of probably the most imaginative recipe can be invited to ESA’s Social Area launch occasion in Darmstadt, Germany, the place our favorite area juices can be served!
Juice the mission can be exploring fuel large Jupiter and its three giant ocean moons: Europa, Ganymede and Callisto. One in every of its key objectives is to grasp if the ocea … read more
