Guardians of the Galaxy

Every hero needs a sidekick. Or, at the very least, a personal videographer.

Case in point: NASA's asteroid-smashing Direct Asteroid Redirection Test (DART) spacecraft, slated to crash into the asteroid Dimorphos on September 26, is currently racing towards its target. But it's not alone! reports that trailing behind the doomed DART craft is a tiny Italian micro-satellite, which, equipped with two optical cameras, will transmit real-time footage of the collision for Earthbound scientists.

Sidecar Vibes

The small Italian craft, dubbed the Light Italian Cubesat for Imaging of Asteroids, or LICIACube, piggybacked its way into space when DART was launched late last year. But we all must fly alone eventually, and on Sunday, LICIACube was deployed from the main craft.

If it's giving big-dog-driving-the-motorcycle-with-little-dog-in-the-sidecar-energy, we concur. Basically: DART will smash into moonlet Dimorphos, which orbits the asteroid Didymos. LICIACube, hovering closeby — but not too closeby — will watch what happens.

"The cubesat will point its cameras toward the asteroid system," Elena Mazzotta Epifani, an astronomer at Italy's National Institute for Astrophysics (INAF), told, "but also to DART, and will probably take some pictures of it."

Cosmic Camcorder

Hopefully, LICIACube will reveal a wealth of information about the unprecedented collision, nevermind the asteroids themselves. Very little is actually known about this asteroid system — so this little cosmic camcorder might just reveal some new, exciting truths about these and other rocks floating through our solar system.

"We do not know almost anything about Dimorphos, which is too small to produce an effect disentangled from the one coming from the main body," Epifani told "We presume from theoretical models on formation of binary asteroids that Dimorphos is very similar to Didymos, but we know virtually nothing about the degree of cohesion of surface materials, the size distribution of the surface debris, and so on."

"Together, DART and LICIACube will analyze for the first time and with high detail the physical properties of a binary near-Earth asteroid," she continued, "allowing us to investigate its nature and have hints on its formation and evolution."

Exciting stuff! One thing's for sure: we'll be watching. Word's still out on Bruce Willis, though.
