Q&A with Scott Bolton, principal investigator on NASA’s Juno mission

A robotic arm extended from NASA’s OSIRIS-REx spacecraft briefly contacted the rugged surface of asteroid Bennu Tuesday to gobble up pristine samples, a climactic moment in the $1 billion mission to bring asteroid material back to Earth in 2023.

Watch a replay of the launch of an Atlas 5 rocket carrying the $1.2 billion SBIRS GEO Flight 4 satellite into orbit.

NASA’s robotic Juno spacecraft wil spend another three years probing the inside of Jupiter, giving the mission more time to meet its primary science objectives after concerns over the health of the probe’s engine prevented it from dropping into a lower, shorter orbit around the solar system’s biggest planet.
