A Mission That Could Reach Mercury on Solar Sails Alone

An innovative proposal would be a first for planetary exploration. Turns out, it’s as tough to drop inward into the inner solar system, as it is to head outward. The problem stems from losing momentum from a launch starting point on Earth. It can take missions several years and planetary flybys before capture and arrival in orbit around Mercury or Venus. Now, a new proposal would see a mission make the trip, using innovative and fuel efficient means.
