Deep down, in an ocean beneath its ice shell, Jupiter’s moon Europa might be temperate and nutrient-rich, an ideal environment for some form of life — what scientists would call “habitable.” NASA’s Europa Clipper mission aims to find out.
“The EIS imagers will give us incredibly high-resolution images to understand how Europa’s surface evolved and is continuing to change,” Cable said.
More About Europa Clipper Europa Clipper’s three main science objectives are to determine the thickness of the moon’s icy shell and its interactions with the ocean below, to investigate its composition, and to characterize its geology.
The Planetary Missions Program Office at Marshall executes program management of the Europa Clipper mission.
NASA’s Launch Services Program, based at Kennedy, manages the launch service for the Europa Clipper spacecraft, which will launch on a SpaceX Falcon Heavy rocket from Launch Complex 39A at Kennedy.
The mission’s goal is to determine whether the ocean beneath Europa’s icy crust contains elements that could support life. A spacecraft is scheduled to launch soon.
Europa, the moon of Jupiter, may be home to a temperate, nutrient-rich ocean beneath its ice sheet, which would make it the perfect habitat for life as we know it. “To find out is the goal of NASA’s Europa Clipper mission.
NASA is now aiming for a launch on Monday, October 14. 14, from Launch Complex 39A at NASA’s Kennedy Space Center in Florida, on a SpaceX Falcon Heavy rocket.
The Europa Clipper spacecraft will be exposed to less intense radiation due to its elongated, looping orbit around Jupiter, which also enables it to make close passes by Europa. Science will be able to “see” the thickness of the moon’s icy shell and learn more about the enormous ocean underneath thanks to a powerful array of instruments used for each of the mission’s 49 flybys. The materials that may have come up from below will be inventoried, organic compounds that are the building blocks of life will be looked for, and any gases released from the moon will be sampled in order to look for signs of habitability.
In order to look for evidence of a water world that could support life, mission scientists will examine the data and probe beneath the moon’s frozen crust.
Morgan Cable, an astrobiologist and member of the Europa Clipper science team at NASA’s Jet Propulsion Laboratory in Southern California, which oversees the mission, said, “It’s important to us to paint a picture of what that alien ocean is like—the kind of chemistry or even biochemistry that could be happening there.”.
Ice Research.
Finding the kinds of salts, ices, and organic matter that are essential components of a planet that can support life is at the heart of that work. This is the role of an imager known as MISE (Mapping Imaging Spectrometer for Europa). The spacecraft’s MISE system, which operates in the infrared, splits reflected light into different wavelengths in order to identify the matching atoms and molecules.
Using an infrared instrument called E-THEMIS (Europa Thermal Emission Imaging System), the mission will also attempt to locate possible hot spots near Europa’s surface, where plumes could bring material from the deep ocean closer to the surface.
The mission of the Europa Imaging System (EIS) is to take precise, high-definition images of Europa’s surface using both a narrow and a wide-image camera. For us to comprehend how Europa’s surface has changed and is changing, the EIS imagers will provide extraordinarily high-resolution images, according to Cable.
Grains and Gazes.
The ice-covered moon Enceladus of Saturn has a massive plume of water vapor erupting from several jets close to its south pole, which was observed by NASA’s Cassini mission. Additionally, Europa has the ability to release hazy water plumes that are drawn from its ocean or internal reservoirs. The Europa-UVS (Europa Ultraviolet Spectrograph) instrument on board Europa Clipper is designed to investigate any material that may be leaking into space and to look for plumes.
MASPEX (MAss SPectrometer for Planetary EXploration/Europa) and SUDA (SUrface Dust Analyzer) will capture the minute pieces of material ejected from the surface, turning them into charged particles to reveal their composition. Whether or not Europa has plumes, the spacecraft carries two instruments to analyze the small amount of gas and dust particles ejected from the moon’s surface by impacts with micrometeorites and high-energy particles.
“The spacecraft will investigate the gas and grains emanating from Europa by extending its tongue to taste the grains and inhaling the gases,” stated Cable.
both within and outside.
Because both aspects have significant effects on whether or not the moon is habitable, the mission will examine Europa’s exterior and interior structure in many ways.
The mission will measure the moon’s induced magnetic field with the ECM (Europa Clipper Magnetometer) and combine that data with measurements of electrical currents from charged particles flowing around Europa — data provided by PIMS (Plasma Instrument for Magnetic Sounding) — in order to obtain insights into the thickness of the ice shell and the existence, depth, and salinity of the ocean.
Additionally, using REASON (Radar for Europa Assessment and Sounding to Near-surface), which can see up to 18 miles (29 kilometers) into the shell, which is itself a potentially habitable environment, scientists will search for information on everything from the existence of the ocean to the structure and topography of the ice. Determining the ice thickness and ocean depth should be made easier by measuring the changes in radio signals caused by Europa’s gravity.
According to Steve Vance, an astrobiologist and geophysicist who works with JPL’s Europa Clipper science team, “non-icy materials on the surface could get moved into deep interior pockets of briny water within the icy shell.”. Some might be big enough to be ponds, or at least big enough to be called lakes. “.
Vance stated that estimates of the temperature profile of the ocean could be obtained by utilizing the collected data to guide comprehensive computer modeling of Europa’s interior structure.
The discovery will usher in a new era in the hunt for extraterrestrial life, regardless of the circumstances. “It is highly likely that Europa Clipper will create just as many questions as it solves—a completely different class than the ones we have been considering for the last 25 years,” Vance stated.
More About Europa Clipper.
The three primary science goals of Europa Clipper are to examine the composition, characterize the geology, and measure the thickness of the moon’s icy shell and its interactions with the ocean below. By thoroughly exploring Europa, the mission will contribute to scientists’ understanding of the astrobiological potential for planets beyond our solar system that may be habitable.
