NASA’s Europa Clipper spacecraft, set to launch in October 2024, may hold the key to uncovering evidence of alien life on Jupiter’s moon Europa. A new experiment has shown that capturing a single ice grain from Europa could potentially reveal signs of life lurking beneath the moon’s icy surface.
Scientists believe that Europa’s subterranean ocean and ice shell could be home to life forms yet to be discovered. The spacecraft’s Surface Dust Analyzer is designed to detect life that may be carried up from the ocean in icy moon plumes. In a laboratory simulation using a bacterium called Sphingopyxis alaskensis, researchers found that even a minuscule amount of cellular material could be detected by the mass spectrometer on board Europa Clipper.
While the spacecraft’s instruments are not able to identify DNA, they can detect fatty acids and lipids, which are essential components of biological cell membranes. This discovery has boosted scientists’ confidence that Europa Clipper’s upcoming instruments will be capable of detecting lifeforms similar to those found on Earth in Europa’s ocean.
The potential discovery of lipid membranes in Europa’s ocean opens up the possibility of detecting even more biological components with Europa Clipper’s instruments. If successful, this could revolutionize our understanding of life beyond Earth and bring us one step closer to answering the age-old question of whether we are alone in the universe. Stay tuned as NASA’s Europa Clipper mission prepares to embark on this groundbreaking journey to explore the mysteries of Jupiter’s intriguing moon.
