Imagine throwing a ball up into the sky so hard & fast it just keeps going - that's our Hera mission, now nearing its target asteroids across millions of km of space.
🛰️ 🪨
But how does Hera know where it is & where it needs to go? That's the task of ESA's Flight Dynamics team https://t.co/caNz4Fnu8k

"NEARLY!"

🚨🚨🚨On its second birthday in space, ESA's Hera mission for planetary defence has spotted its asteroid destination for the first time, from an approximate distance of 236 500 km away!

The Didymos system is actually two asteroids, seen as a single pixel for now

Launched two years ago today, ESA's Hera mission for planetary defence is preparing for its single most challenging activity since lift-off: the sustained braking manoeuvre allowing it to approach its target asteroids: https://t.co/zObl2XgmFa

🎂Happy birthday Hera🛰️! ESA’s asteroid mission for planetary defence lifted off two years ago today!

📽️But where is Hera about to arrive at, and how might its discoveries one day help save planet Earth...?

The ESA-JAXA Ramses planetary defence spacecraft has been turned on for the first time by its prime contractor @OHB_SE in Italy – marking a major milestone in its time-critical development schedule: https://t.co/pnqsYvrOeu

[ESA's Hera mission @ESA_Hera]

Currently speeding through space at 12 km/s, ESA’s Hera spacecraft is due to reach its target Dimorphos asteroid this November. But if an astronaut were magically teleported onto Hera, what would they see & what would it happen if they let themself fall? https://t.co/1dNnAW7seT

Any questions? You can ask our Hera Space Companion right now - our AI fed with approved operational, scientific and technical knowledge, making ESA’s first planetary defence mission accessible to everyone! https://t.co/KpoYIU1AvT

[Josef Aschbacher @AschbacherJosef]

The International Space Summit marked an important step in shaping a common European vision for space exploration. Europe has now started a course towards greater autonomy in low Earth orbit, a stronger role in lunar exploration, and a more competitive European space sector, while remaining a reliable partner in international exploration efforts.

@ESA will work closely with its Member States in the months ahead, to support decisions later this year. The work continues from the Summit, through to ESA's Intermediate Ministerial Meeting in December, and onto our Council Ministerial in 2028 and beyond✨

An asteroid killed the dinosaurs because they didn’t have a space agency – so ESA’s Hera asteroid mission has a dino mascot (also aboard in real life!).

But our dino needs a name – that’s where you come in!

Suggest a winning name to join us at the unveiling of Hera’s 1st image in November: https://t.co/lswnHOS0la

Will we be passengers or pilots? Customers or service providers? Tenants or architects? At the International Space Summit, I argued that Europe must take steps now to shape its own future in space.

[Josef Aschbacher @AschbacherJosef]

Last night we brought together astronauts, ministers, industry leaders and space enthusiasts to celebrate the imagination, innovation and cooperation that define Europe's journey in space.

From Earth orbit to deep space, we were reminded that today's ambitions become tomorrow's achievements.

Today we begin to shape Europe's future in space. #ParisSpaceSummit

Metre-sized meteoroid 2026 RW1 (previously known as CERNQ52) hit the ocean off NW Australia on Sunday afternoon - but the impact was forecast roughly six hours in advance, using ESA’s Meerkat automated system for predicting imminent impactors!

[ESA's Hera mission @ESA_Hera]

The mysteriously smooth, youthful face of Mars moon Deimos could be due to an asteroid impact - a thick layer of dust from the impact serving as the planetary equivalent of cosmetic fillers.

The study was guided by Hera's 2025 Mars flyby, with help from Sir Brian May: https://t.co/YlUv944USV

[ESA's Hera mission @ESA_Hera]

The Hera planetary defence mission and its two CubeSats are being prepared by their controllers to fly themselves in deep space, to avoid crashing into their asteroid targets - and each other!
