The potential of a human mission to Mars has captured the imagination of many recently. However, before astronauts set foot on the Red Planet, NASA first plans to visit Near-Earth asteroids and potentially to the moons of Mars.

QE2 Asteroid Hurtles Past Earth On May 31
2013-05-30 13:20:39

On May 31, a 1.7-mile-wide asteroid called QE2 will hurtle past Earth at a distance of 3.6 million miles. While that distance is far enough for the asteroid to be considered non-threatening, it is close enough to excite NASA astronomers.

Scientists Gathering To Discuss NEO Threat Mitigation
2013-05-08 18:57:57

Scientists around the world are meeting in Spain this week to talk about the threats that asteroids pose to Earth.

Monitoring Elusive Collisions In Space
2013-04-24 06:09:40

Asteroids and other objects in our solar system collide often, but researchers are not always able to detect or track such impacts from Earth. This means that we are sometimes caught unaware by the "rogue debris" created by the impacts.

Human Asteroid Exploration: The Long And Storied Path
2013-04-17 10:43:01

Within NASA’s new FY2014 budget proposal lies a project known as the Asteroid Retrieval and Utilization Mission. This project would be the first to capture a small near-Earth asteroid and safely redirect it to a lunar orbit so that astronauts can visit and explore it. Such a mission would expand scientific knowledge of the origins of both humanity and the universe.

Targeting An Asteroid

Near-Earth Object -- Near-Earth Objects (NEO) are asteroids, comets and large meteoroids whose orbit intersects Earth's orbit and which may therefore pose a collision danger. Due to their size and proximity, NEO's are also more easily accessible for spacecraft from Earth and are important for future scientific investigation and commercial development. In fact, some near-Earth asteroids can be reached with much less ΔV (change in velocity) than the Moon. In the United States, NASA...

Near-Earth Asteroid -- Near-Earth asteroids (NEAs) are asteroids whose orbit intersects Earth's orbit and which may therefore pose a collision danger, as well as being most easily accessible for spacecraft from Earth. In fact, some near-Earth asteroids can be reached with much less ΔV than the Moon. The most famous near-Earth asteroid is 433 Eros that was visited by NASA's Near Earth Asteroid Rendezvous probe. A few hundred such near-Earth asteroids are known, ranging in size up...

433 Eros -- The asteroid 433 Eros was named after the Greek god of love Eros. It is an S-type asteroid approximately 13 x 13 x 33 km in size, the second-largest near-Earth asteroid. It was visited by the NEAR Shoemaker probe, which first orbited it taking extensive photographs of its surface and then in 2001 at the end of its mission was landed on the asteroid's surface using only its maneuvering jets. Depending on where they stood on Eros, a person who weighed 200 pounds (90...
