The International Space Station (ISS) U.S. National Laboratory is preparing to receive a powerful new 3D holographic microscope named ELVIS (Extant Life Volumetric Imaging System), which could help scientists in the search for extraterrestrial life.
Spearheaded by researchers from Portland State University in collaboration with NASA’s Jet Propulsion Laboratory, ELVIS will hitch a ride on SpaceX’s 32nd Commercial Resupply Services (CRS) mission, currently scheduled to lift off from NASA’s Kennedy Space Center no earlier than 4:15 a.m. EDT on Monday, April 2.
“Using innovative holographic technology to deliver detailed 3D views of cells and microbes, the system allows scientists to study the adaptability and resilience of life under extreme conditions,” explained the ISS U.S. National Lab in a statement. “Knowledge gained could reveal how life might persist on distant moons and planets, significantly enhancing our search for life outside Earth.
Following the potentially historic news that researchers using the James Webb Space Telescope may have discovered the first proof of life on another planet, the delivery of ELVIS marks yet another step in the increasing efforts to leverage advanced tools and technologies that could assist in confirming the presence of extraterrestrial life. However, unlike the powerful tools aboard the JWST that can capture light from distant stars and galaxies, ELVIS allows scientists to study microbiological samples in an unprecedented 3D holographic format.
According to the announcement, Elvis goes beyond the typical 3D microscope, allowing scientists to study the “intricate structure, volume, and environmental interactions of organisms at a cellular level.” This enhanced visualization and detail will enable the scientists aboard the International Space Station to make increasingly accurate biological assessments “that could shed light on the ability of life to thrive in the most extreme environments of space.”
Alongside current efforts to search for extraterrestrial life on Mars, the world’s space agencies are eying several potential missions to the solar system’s icy worlds, including the upcoming Europa Clipper Mission, which some believe will be the first mission to find extraterrestrial life. The most tantalizing targets include the subsurface oceans on Jupiter’s moon Europa, Saturn’s moons Enceladus and Mimas, and the dwarf planet Pluto.
Although several inventive methods have been proposed to tackle the difficulty of collecting samples from these moons, including capturing seawater droplets from Enceladus and Europa that are ejected into space and robots that drill beneath the ocean surface, identifying whether or not a sample collected from somewhere beyond Earth is biological is still an unkn own factor. According to the ISS U.S. National Lab team, this is precisely the type of work ELVIS was designed to do.
“This study goes beyond merely observing organisms; it tests their observable and genetic adaptations to microgravity,” they explained. “The insights gained could illuminate how life might survive beneath the icy shells of distant moons like Europa and Enceladus.”
Once aboard the ISS, scientists will use ELVIS to study two of the most resilient life forms found on Earth: Euglena gracilis, a microalga known for its high adaptability, and Colwellia psychrerythraea, a bacterium that has been found thriving in frigid ocean waters. Understanding how organisms like these survive and thrive in extreme environments, such as the flourishing ecosystem found beneath deep-sea hydrothermal vents or the life-filled lake underneath 14 meters of Antarctic ice, is considered critical to astrobiologists who are preparing to encounter life that is specifically adapted to life in environments like those found in subsurface oceans.
“We are thrilled to leverage the ISS National Lab to prepare ELVIS for its future roles in space exploration missions,” said Jay Nadeau, a physics professor at PSU and the project’s principal investigator. “The successful operation of ELVIS in the demanding conditions of space not only paves the way for its use in off-Earth environments but also holds implications for enhancing biomedical and microbiological research on our planet.”
