NASA has announced more details about its Asteroid Redirect Mission (ARM), which no longer includes an attempt to capture an entire asteroid. When the craft arrives in 2022, it will use robotic arms to pick and secure a small boulder from the asteroid, and will spend a number of years towing the boulder into a stable orbit between the Earth and the Moon. The space agency plans to send a team of astronauts to study the boulder in 2025 using the Orion capsule, the same spacecraft that should eventually bring the first humans to Mars. The three being considered — Itokawa, Bennu, and 2008 EV5 — have all been closely studied or even visited by other spacecraft, so the mission should be less risky than sending a probe to explore a comet that's a half-billion miles away.
