NASA Preps Mission To Search For Life On Europa, One Of Jupiter’s Moons
The celestial body with the greatest potential for life in the solar system may not be Mars after all. Europa, one of Jupiter’s moons, is believed to have an ocean just beneath its frozen crust — and some scientists think it may have just the right ingredients for life.
Now, NASA is getting ready to send a spacecraft there to find out more.
“We know that on Earth, everywhere that there’s water, we find life,” Robert Pappalardo, Europa Mission project scientist, said in a video released by the space agency. “So could Europa have the ingredients to support life?”
Pappalardo also wrote a blog post about the Europa mission last month for The Huffington Post. “Finding life elsewhere would end our cosmic isolation: if there is life in our own planetary backyard, then life is probably common throughout the universe,” he wrote at the time.
Europa is one of the four largest moons of Jupiter, which were discovered by Galileo in 1610. Along with its icy crust and the possible ocean beneath, the moon is known for the red streaks across its surface.
“There is too much evidence right now lying around on the surface — the red stuff — that suggests that something’s going on there,” Claudia Alexander, who was mission project manager of the Galileo spacecraft, which circled Jupiter and its moons in the 1990s, said in the clip. “Is that an environment that is habitable for any sort of life form? By golly, we really have got to go back and figure that out.”
The potential mission to Europa passed its first major review last week, and is now headed toward a phase of development called formulation. If everything goes according to plan, the spacecraft will launch in the 2020s —> Read More
