NASA Wants To Go To Europa 216
MightyMartian writes "'NASA and the White House are asking Congress to bankroll a new intrastellar road trip to a destination that's sort of like the extraterrestrial Atlantis of our solar system — Jupiter's intriguing moon, Europa.' Since Europa seems one of the most likely worlds in the Solar System other than Earth where we have some hope of finding extant life, let's hope Congress gives the green light to this project."

Ground breaking, paradigm shifting revolutions in science are rarely in applied research, it's in basic research. And likewise, space exploration has rather few immediate gains, but the needs of space exploration often lead to other discoveries that have very earthly applications. When you look at the early space programs, up to and including the moon shot, it sure gave us paradigm changes and developments we would not have seen without. From "hard" science, like electronics, computers and safety to "soft" science in the fields of organization and process analysis and optimization. These things were a necessity for the space programs but they also led to development and a boost to these other fields that we now take for granted but would most certainly not be even close to where we are today without the needs of a space program.
My pet example in this context is lasers. The theory behind them was developed as early as the 1920s. It took until the 1960s for a laser to become reality. Only in 1980 it became economically feasible. But our modern economy, especially our entertainment industry, could not even consider existing without it. That's certainly not what the inventor had in mind, but that's where it is used today, with great success. Who can predict what great developments and discoveries could come out of the obstacles faced by this project? I'd say we could easily end up with revolutionary discoveries in the fields of metallurgy, superconductivity, generation/transfer/storage of electrical energy, information transport, imaging along with a better and more efficient handling of process organization and management.
