NASA plans a robotic mission to search for life on Europa | io9
It looks like it’s finally going to happen, an actual mission to Jupiter’s icy moon Europa — one of the the solar system’s best candidates for hosting alien life.
Yesterday, NASA announced an injection of $17.5 billion from the federal government (down by $1.2 billion from its 2010 peak). Of this, $15 million will be allocated for “pre-formulation” work on a mission to Europa, with plans to make detailed observations from orbit and possibly sample its interior oceans with a robotic probe. Mission details are sparse, but if all goes well, it could be launched by 2025 and arriving in the early 2030s.
This is incredibly exciting. Recent evidence points to a reasonable chance of habitability. Its massive subsurface ocean contains almost twice as much water as found on Earth. The water is kept in liquid state owing to the gravitational forces exerted by Jupiter and the moon’s turbulent global ocean currents. The good news is that a probe may not have to dig very deep to conduct its search for life; the moon’s massive plumes are ejecting water directly onto the surface.
I was just a 17-year old kid from the Bronx with dreams of becoming a scientist, and somehow the world’s most famous astronomer found time to invite me to Ithaca in upstate NY and spend a Saturday with him.
I remember that snowy day like it was yesterday. He met me at the bus stop. He showed me his laboratory at Cornell University. Carl reached behind his desk, and inscribed this book (Cosmic Connection) for me:
For Neil Tyson,
With all good wisdom to a future astronomer.
- Carl Sagan
At the end of the day, he drove me back to the bus station. The snow was falling harder. He wrote his phone number, his home phone number, on a scrap of paper. And he said, “If the bus can’t get through, call me. Spend the night at my home, with my family.”
I already knew I wanted to become a scientist, but that afternoon I learned from Carl the kind of person I wanted to become. He reached out to me and to countless others. Inspiring so many of us to study, teach, and do science. Science is a co-operative enterprise, spanning the generations. It’s the passing of a torch from teacher to student to teacher. A community of minds reaching back from antiquity and forward to the stars.
