NASA is about to grab its first-ever taste of an asteroid. On 20 October, some 334 million kilometres from Earth, the agency’s OSIRIS-REx spacecraft will approach a dark-coloured, diamond-shaped asteroid named Bennu, with the aim of touching its surface for a few seconds — long enough to hoover up a collection of dust and pebbles. If successful, the spacecraft will then fly this carbon-rich rubble back to Earth, where scientists can probe it for clues to the history of the Solar System.
OSIRIS-REx spacecraft is about to execute a nail-biting manoeuvre to scoop up rock samples from the asteroid Bennu and send them back to Earth. OSIRIS-REx spacecraft is about to execute a nail-biting manoeuvre to scoop up rock samples and send them back to Earth.
