ESA's newest planetary defender has opened its eye to the cosmos for the first time

The Flyeye telescope’s ‘first light’ marks the beginning of a new chapter in how we scan the skies for new near-Earth asteroids and comets.

It’s a question of when, not if, Earth will be hit by a large asteroid causing catastrophic consequences. How do we keep Earth safe? #PlanetaryDefence has innovative strategies, including kinetic impactors & nuclear deflection techniques, designed to alter the trajectory of these cosmic intruders. 🧪

Ramses and the Apophis flyby will be super exciting for #PlanetSci and #PlanetaryDefence. On top of all the detailed science, the closeness should allow near real-time streaming of HD video from the surface of the #asteroid at the same time as some parts of the world can see it from the ground!

It's 1500 days until the asteroid Apophis makes a close but entirely safe flyby of Earth on 13 April 2029! ESA's proposed Ramses mission would rendezvous with Apophis and study how it changes during the flyby. The mission's first CubeSat has been selected. 🪨🛰️

My favourite thing about these asteroid missions is the low-key implication that we are bigmad that space rocks wiped out the dinosaurs, and we are avenging their extinction with missions like DART and Hera.

Two men stand next to a large television display showing an artist's depiction of the Hera spacecraft passing by Mars. On a table next to one of the men astride a laptop are two cute dinosaur plushies, one a dark green T-rex, and the other a light blue herbivore, maybe a brachiosaur.
