Here Are the Science Instruments NASA Will Use to Explore Europa
NASA just announced the science instruments that will be used to understand the enigmatic ocean moon of Europa. The mission is planned to launch sometime in the early 2020s.
NASA's Mission to Europa May Get More Interesting Still
NASA officials have asked their European counterparts if they would like to propose contributing a small probe to NASA's Europa mission planned for the mid-2020s.
It's Official: We're On the Way to Europa
NASA's 2016 budget request increases the space agency's budget by $519 million, starts a new mission to Europa, increases funds to Commercial Crew, and threatens some long-running planetary missions.
JUICE at Europa
Europe's JUICE spacecraft will provide us with a detailed regional study of this icy moon of Jupiter.
A Mission to Europa Just Got a Whole Lot More Likely
Rep. John Culberson, an outspoken supporter of Europa exploration, will assume leadership of an influential congressional committee that funds NASA.
Europa: How Less Can Be More
Van Kane explains three factors that make exploring Europa hard—factors that can make a mission concept that seems like less actually be more.
Mars and Europa: Contrasts in Mission Planning
Several announcements for proposed missions to Mars and on the planning for a NASA return to Europa that highlight the contrasts in planning missions for these two high priority destinations.
Capitol Hill Responds to the Lure of Europa
A standing-room only crowd learned the lure of Europa, the moon of Jupiter with more liquid water than the Earth, at a special Planetary Society event on capitol hill.
A Reluctant Dance Towards Europa
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.
Your Europa Mission Primer of the Day
Trying to understand NASA's current efforts to explore Europa? Read this excellent piece on the recent, frustrating history to scout out this watery moon of Jupiter.
[Updated] To Europa!...Slowly. First Impressions of NASA's New Budget Request
Europa may get a mission...eventually. We give our first take on the 2015 NASA Budget request. How does Planetary Exploration fare? Which projects were cancelled? Will NASA capture an asteroid? And most importantly, what can you do about it?
NASA Wants to Explore Europa On the Cheap
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 New Frontiers Mission? (Or why I like the Europa Clipper concept even more now)
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.
Europa: No Longer a "Should," But a "Must"
We've waited long enough, Europa cries out for exploration and discovery. It's time to heed that cry.
Planetary Radio: Rise of the Europa Underground?
This week's PlanRad talks to one of the creators of a new effort to build support for the Europa Clipper, a spacecraft that would tell us far more about what's going on under that icy moon's surface.
NASA's Europa Mission Concept Rejects ASRGs -- May Use Solar Panels at Jupiter Instead
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.
First Analysis: the NASA Planetary Science Budget for 2014
No mission to Europa, diminished funding for outer planets missions, a small bump to small spacecraft missions, and an increase for asteroid detection are part of the White House's proposal for NASA in 2014.
Europa on the Ropes
For now, Mars continues to eclipse Jupiter's moon Europa (shown here to scale) in NASA's flagship mission plans, but not in its appeal to many planetary scientists.
