NASA’s Mars Exploration Analysis Group (MEPAG) recently reviewed plans by Europe, the Japanese, and NASA for future Mars exploration. The prognosis is for another exciting decade of Mars exploration.
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.
In December, scientists announced the discovery of possible plumes of water being ejected from Jupiters’s moon Europa. If confirmed, Europa would be the second moon with confirmed plumes after Saturn’s moon Enceladus. Two Discovery mission proposals for Enceladus suggest the types of missions that may be proposed for Europa.

The President’s proposed Fiscal Year 2015 budget details were released last week. For the next several years, the budget proposes a steady as she goes plan, but with two “what are they thinking?” surprises.
Imagine flying deep within the asteroid belt to study the most unreachable location in the solar system: the deep core of a terrestrial world.
To paraphrase Forrest Gump, the Discovery program is like a box of chocolates – you never know what you’re going to get. The creativity of the scientific community has given us a wide assortment of missions in the past and is likely to surprise and delight us again.
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 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.
ASRGs could have stretched NASA's limited supply of plutonium to potentially enable missions to the perpetually-shadowed polar craters on our moon, to flyby Uranus, or to float for months on a Titan lake.
