On September 26, when NASA's DART mission collides with the asteroid Dimorphos, there will be a silent witness:
LICIACube, an Italian cubesat that will stream the groundbreaking experiment live for interested researchers on Earth.
A 31-pound (14 kilogramme) micro-satellite called LICIACube, or the Light Italian Cubesat for Imaging of Asteroids,
has travelled to the Didymos-Dimorphos binary asteroid system through DART (the Double Asteroid Redirection Test).
The cubesat was launched by DART on September 11 at 7:14 p.m. EDT (2314 GMT),
allowing LICIACube 15 days to position itself safely to see DART collide with Dimorphos.
The impact is a groundbreaking experiment intended to modify a space rock's orbit as a critical test of a planetary defence idea that
