Discovery Missions for an Icy Moon with Active Plumes

Posted by Van Kane on 2014/04/02 07:31 CDT | 8 comments

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.

Europa New Frontiers Mission? (Or why I like the Europa Clipper concept even more now)

Posted by Van Kane on 2014/01/07 05:14 CST | 3 comments

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

Posted by Van Kane on 2013/12/27 04:49 CST | 2 comments

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.

NASA's Europa Mission Concept Rejects ASRGs -- May Use Solar Panels at Jupiter Instead
Untested technology is too risky

Posted by Casey Dreier on 2013/09/05 06:41 CDT | 6 comments

The Advanced Stirling Radioisotope Generator (ASRG) is no longer an option for powering a potential Europa mission. The ASRG uses Plutonium-238 to generate electricity, but is far more efficient than past RTGs.
