Our Pathway to Exploration Should Start with the Asteroid Redirect Mission

Louis D. Friedman and Tom Jones • June 30, 2014 • 51

Despite its rejection by the NRC Committee, we argue that the Asteroid Redirect Mission (ARM) is an affordable and logical first step in such a sequence. ARM is not only consistent with the NRC Committee’s own principles, but is also the only near- term initiative that can shape their recommendations into a sustainable human space exploration program. ARM would launch U.S. explorers into deep space beyond the Moon, and fits logically into an exploration program aimed at Mars.

Discovery Missions for an Icy Moon with Active Plumes

Van Kane • April 02, 2014 • 8

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.
