Adventures in near-Earth object exploration.

چکیده
Asteroids, because of the hazard they pose to Earth, are compelling targets for robotic and human space exploration. Yet because of their exotic low-gravity environment, simply landing on an asteroid appears to be much more challenging than we had appreciated 5 or 10 years ago. Thanks to a bold new mission from Japan that has made the first asteroid sample return attempt, this goal is now within our reach.

Among proposed flexible path destinations are near-Earth objects, those asteroids and comets having perihelions of less than 1.3 astronomical units and periods of less than 200 years. Heliocentricorbit element criteria have been developed with the objecti...
متن کاملInto the Beyond: a Crewed Mission to a Near-earth Object
ABSTRACT Aside from the exploration of Mars, the objects that most capture our interest for a new human visit are the Near-Earth Objects (NEOs). These objects are ideal candidates for deep space operations and explorations as we extend the human presence out into the solar system. The notion of a crewed mission to a NEO was first discussed in the Apollo era. The most recent assessment has been ...
متن کاملNear - Earth Objects
Because the NEO population is constantly evolving and being replenished from the main asteroid belt and cometary reservoirs, it consists of objects with a variety of compositions and internal structures. These objects present unique opportunities for future planetary science goals and exploration. In order to realize these opportunities for future NASA studies, an expanded program for NEO disco...

Within the context of both manned and robotic spaceflight activities, orbits near the Earth-Moon L1 and L2 libration points could support lunar surface operations and serve as staging areas for future missions to near-Ear...
متن کاملFrom Inner Earth to Outer Space
On a cold day in February 2001, a spacecraft landed on 433 Eros, an asteroid between the orbits of Mars and Jupiter. The spacecraft had completed its five-year journey to investigate fundamental questions about the nature and origin of near-Earth objects for the first time. The technical demands of the Near Earth Asteroid Rendezvous NEAR-Shoemaker (NEAR) mission were immense. A multidisciplinar...
