If Uranus could reveal so much, providing us with a huge piece of the solar system puzzle, why haven't we already sent a probe?
Mark Hofstadter, planetary scientist at NASA's Jet Propulsion Laboratory and U.S.-lead investigator for Uranus Pathfinder, points out that before now the logistics of such a mission have been considered too expensive when considering the science that can be gathered.
"Being farther away makes it more difficult (read more expensive) to get there than to, say, Jupiter or Saturn," Hofstadter said. It's for this reason that missions to the inner gas giants have been preferred. But, in light of technological advancements, the cost of sending a robotic mission to Uranus now is more manageable.
In addition, the relative scientific importance of Uranus has been on the rise.
"This is due to past missions answering some questions at Jupiter and Saturn, but just as importantly, recent research - both theoretical and observational - has made us appreciate that the Ice Giants are very important if we are to understand the formation and evolution of planets both in our solar system as well as around other stars," he said.
