Asteroids, Mars, and a vision for space beyond colonialism

Who owns an asteroid?

Celestial bodies like Bennu could help us tell Earth’s origin story. Or they could be strip-mined for resources

Discussions around space travel are saturated in colonialist language and narratives, from “space colonies” on Mars to multiple proposals for mining asteroids. These concepts are often treated as inevitable, with conversations about when and how, rather than if we should do any of this in the first place. In The Nib, artist extraordinaire Maki Naro and I look at how colonialist attitudes have colored our dialog on asteroids and Mars, with a focus on the ethical and — dare we say — the spiritual component of conservation on other worlds.

There (to an asteroid) and back again: a robot’s journey

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]
