Scientists say NASA’s plan in 2030 He said he could confirm alien life when he launched his $178 million ship at Jupiter’s moon. explained.
American Space Agency NASAwill launch the Europa Clipper in October for its five-and-a-half voyage to Europa, where it will spend four years investigating the icy moon.
Now, a new study analyzed instruments on board to find that they were able to harvest a single living cell in a tiny grain of ice thrown from the moon’s oceans.
University of Washingtondetermined that the instruments could detect microbes in one of hundreds of thousands of ice grains and identify chemicals that are essential components of life on Earth.
Editor-in-Chief Fabian Klenner “For the first time, we have shown that even a small fraction of cellular material can be identified with a mass spectrometer on a spacecraft. Our results give us further evidence that, using upcoming instruments, we will be able to detect life forms similar to those on Earth that we increasingly believe could be found on ocean-bearing satellites,” he said. It gives a lot of confidence.”
NASA chose to study Europa because it is full of water and certain nutrients—all of which could mean the Moon supports life.
Scientists have previously determined that for a planet to have life, it must have three main components: temperatures that allow liquid water to exist; the presence of carbon-based molecules and an energy input such as sunlight. Jupiter’s moon Europa seems to have it all.
A total of five spacecraft have visited the distant planetary body, but Clipper is set to include the most powerful instruments of any previous mission and was developed for the purpose of searching for life.
The new study focused on a common bacterium called Sphingopyxis alaskensis, found in waters off the coast of Alaska.
The researchers chose this specimen because it is tougher than most modeled organisms and because of its ability to survive in cold environments with sparse nutrients – characteristics similar to those that life on Europa would encounter.
The Clipper mission aims to find out whether Europa, Jupiter’s fourth largest moon, hosts conditions suitable for life using a ‘sophisticated suite of science instruments’.
Smaller“They are extremely small, so in theory they could fit in grains of ice emitted from an ocean world like Enceladus or Europa,” he said.
The simulation included a scenario of Clipper’s Surface Dust Analyzer (SUDA); This will collect the ice grains that come into force and identify their chemistry.
SUDA can uniquely detect salts in dust/ice grains. The speed and direction of the grains will tell Suda their origin on Europa’s surface, NASA said in a statement.
The device will also detect negatively charged ions, allowing it to harvest fatty acids and lipids.
“For me, looking for lipids or fatty acids is more exciting than looking for the building blocks of DNA, and that’s because fatty acids seem to be more stable,” Klenner said.
Senior author Frank Postberg, professor of planetary sciences at Freie Universität Berlin He said: ‘With appropriate instrumentation, such as the Surface Dust Analyzer on NASA’s Europa Clipper space probe, finding life or traces of it on icy moons may be easier than we thought. “Of course, if there is life there and it takes care to be enclosed in ice grains originating from an environment such as an underground water reservoir.”
The spacecraft will be launched from NASA’s Kennedy Space Center in Florida on a Falcon Heavy rocket belonging to Musk’s company.
