The road to lower costs outer planet missions has been paved by NASA’s first two New Frontiers missions, the $700M New Horizons mission to Pluto and the $1.1B Juno mission to Jupiter. But can the cost of a mission to the outer solar system be cut to $450M, the limit for a Discovery mission?
A newly published paper confirms a subsurface ocean at Ganymede. An ocean there was already suspected from its magnetic field and predicted by geophysics; new Hubble data confirms it, and even says it is in the same place we thought it was before. Such consistency is rare enough in planetary science to be worth celebration.

Rep. John Culberson, an outspoken supporter of Europa exploration, will assume leadership of an influential congressional committee that funds NASA.
Jason Perry brings us a report on recent ground-based observations that shed new light on the most powerful of Io’s volcanic eruptions.
Watch Bill Nye and Special Guests in The Lure of Europa
Video from The Planetary Society's recent congressional event

We've posted the full video of our Washington, D.C. event exploring the lure of Europa, the moon of Jupiter with more liquid water than the Earth.
A Reluctant Dance Towards Europa
or, Why A Credible Europa Mission is Likely to Cost ~$2B
For the last two years, NASA has been the shy partner refusing to get on the dance floor, and Congress has been the aggressive partner insisting on a dance now. The dance is the continuing attempt by Congress to have NASA commit to a mission to explore Europa, and NASA’s attempts to delay a mission well into the 2020s.

Simon Kattenhorn and Louise Prockter may finally have found subduction zones on Europa, which would it the only other place in the solar system besides Earth that is known to have active plate tectonics.
NASA Wants to Explore Europa On the Cheap
Will science suffer with this arbitrary cost-cap?
NASA announced today that their Europa mission concept studies will be for a sub-$1 billion spacecraft, a lower level than previously imagined for a mission to this watery moon.
Europa remains a top priority for a future mission to explore whether it could host life. While the Europa Clipper mission, remains the current front runner, a senior NASA manager has suggested that the agency may look at still lower cost options. Van Kane looks at what those options might be.
NASA’s New Planetary Mission Woes
Budget cuts slow down the rate of new missions
NASA’s planetary science program depends on regular missions to solar system bodies to gather data. A combination of budget cuts and previous commitments to develop missions currently in the pipeline means that development of follow on missions may slow to a crawl. Van Kane looks at the current situation and NASA’s plans and then look at options the agency may consider if budgets remain tight into the next decade.
It's time to reassess Europa exploration, past, present and future. The Destination Europa! session at AGU, inspired by the eponymous website and movement, didn't take exactly that message as its theme, but it's what I got from the presentations. What an ELECTRIFYING meeting this has been for Europa exploration!
