Asteroid & Comet Missions

Hey NASA, you've just landed your first samples from an asteroid! Where are they going next? Houston, of course.

The Virtual Telescope Project will point its telescopes towards NASA's OSIRIS-REx spacecraft on Sept. 23 as it approaches Earth to return a sample of the asteroid Bennu.

The first asteroid samples ever collected by NASA are closing in on Earth for a historic landing in Utah today (Sept. 24).

NASA's OSIRIS-REx mission is set to deliver its asteroid sample to Earth on Sunday morning (Sept. 24), and you can watch the historic action live.

Asteroid Bennu is the space rock with the highest known probability of hitting Earth in the next 200 years. NASA's OSIRIS-REx mission will help us protect ourselves.

Space germs will not piggyback on bits of Bennu that NASA's OSIRIS-REx delivers to Earth this Sunday. Here's why.

Scientists with NASA's OSIRIS-REx mission are confident that the planned Sept. 24 asteroid sample landing will go as planned.

NASA's first asteroid sample mission has landed at post offices two days before the spacecraft's return capsule is set to land on Earth. The USPS released a stamp celebrating the OSIRIS-REx probe.

NASA's OSIRIS-REx spacecraft is carrying the first ever asteroid samples recovered by the agency. Now, after a 1.2 billion-mile journey back to Earth, it's about to land.

A ground-based telescope in the Canary Islands snapped a photo of NASA's OSIRIS-REx probe on Sept. 16, eight days before its asteroid sample lands on Earth.
