This Thursday, the OSIRIS-REx robotic probe will launch from Cape Canaveral in Florida, destined for asteroid Bennu. I can’t ride with the probe, but I’m doing the next best thing: going to Florida to watch the launch, alongside scientists involved in the project. Here’s a preview, written for New Scientist:

NASA probe about to leave for asteroid Bennu and bring bits home

For New Scientist:

Bennu or bust. On 8 September, the OSIRIS-REx probe will leave Earth for the asteroid Bennu, and will return with souvenirs: up to 2 kilograms of material from its surface.

OSIRIS-REx (Origins, Spectral Interpretation, Resource Identification, Security-Regolith Explorer) is the latest in a string of sample return missions, following the Stardust mission to the comet Wild 2 and the Hayabusa mission to asteroid Itokawa. Both of those missions hit hurdles, and neither brought more than a few grains of material back to Earth.

OSIRIS-Rex will pioneer a new and ambitious technique for gathering samples: a robotic arm equipped with a vacuum cleaner. [Read the rest at The New Scientist]
