ESA Technology

Dear space community, we are expanding our horizons! You can now find us on: 🟦 Bluesky: bsky.app/profile/techno… 🟨 LinkedIn: linkedin.com/company/esatec… See you there! 👋

Hera's space odyssey across the cosmos is underway! Much like Odysseus learned the mysteries of his world, #Hera too will probe the possibilities of our universe and its celestial bodies. Learn more about why so many space missions are connected to Greek mythology here: esa.int/Space_Safety/H…

Operating across 140 million km of space from ESOC's Interplanetary Control Room (left), ESA’s Hera mission team has upgraded the software running it - leaving the spacecraft ready to explore the distant Dimorphos and Didymos asteroids this autumn esa.int/Space_Safety/H…

Views of 2 new asteroids! The Hera team congratulates @JAXA_en 's Hayabusa2 for flying by 450-m diameter Torifune (l) and @CNSA_en's Tianwen2 for arriving at tiny 18-m Kamoʻoalewa (r). Hera reaches Dimorphos this autumn - the 1st asteroid to have been changed by human action!

The European Space Agency has contracted Spanish company @emxys for the first CubeSat designed to operate on an asteroid's surface. It will be deployed by ESA's Ramses mission onto asteroid Apophis as it passes close by Earth on Friday 13 April 2029 esa.int/Space_Safety/P…

Humans changed an🪨asteroid - now we find out how! Especially for Asteroid Day,🎥watch the full story so far of our Hera mission🛰️, on its way thru deep space to probe the first Solar System body transformed by human action💥: esa.int/ESA_Multimedia…

Want to know about our Hera asteroid mission for🪨Asteroid Day, which is on its way to the 1st asteroid changed by human action? Watch our cartoon series, starting here 👉 esa.int/ESA_Multimedia…

Happy #AsteroidDay ! But why today of all days? Find out here, along with eight other key dates in asteroid history! esa.int/Space_Safety/P…

It's hot outside, and the 1-km-scale asteroid (152637) 1997 NC1 flies by at lunchtime. Why not stay in and follow the Asteroid Day Festival, live from Luxembourg? Bringing together astronauts, asteroid experts and space mission engineers, the action starts at 10 am: youtube.com/watch?v=FacoaT…

🚀 Visit ESTEC, our technology centre in the Netherlands, on 26-27 September! ✨ Saturday 26 September - dedicated to visitors with a disability and their carers ✨ Sunday 27 September - general open day 🔗 Registration opens later this summer, keep an eye on our socials! In the meantime, save the date! 👇

🛰️I'm currently speeding my way thru deep space to the Dimorphos🪨asteroid, the only Solar System body whose orbit has been shifted by human action - when NASA's DART spacecraft💥impacted it - to check what happened to it next! See where I am right now: whereis.space/hera/

Saturday’s sonic boom heard over Boston was due to an airbursting meteor, as confirmed by US weather satellite GOES-19. A European geostationary weather sat performs a comparable skywatch, read more here: esa.int/Space_Safety/F…

Everything you wanted to know about asteroids but were afraid to ask... ! Hera Principal Investigator Patrick Michel has a new book out on planetary defence & asteroids - in 🇫🇷 - odilejacob.fr/catalogue/scie…

Congratulations to @NASA's @MissionToPsyche for their spectacular Mars flyby. The images brought back memories of our visit last year - asteroid missions like Mars; its gravity comes in handy for modifying course! esa.int/Space_Safety/H…

The international #HeraMission science community is meeting at Thessaloniki 🇬🇷 this week, preparing for Hera's arrival in 6 months time to the Dimorphos asteroid orbiting the larger Didymos, to see how it was transformed by the impact of @NASA's spacecraft back in 2022

You’re left with a showstopper bake that is sure to impress the judges – oh wait – we mean the planetary protection experts, of course! 😉 Your squeaky-clean parachute is ready to safely land the #ExoMars Rosalind Franklin rover on Mars. Here’s how the experts do it: esa.int/ESA_Multimedia… @ESA_Exomars @esaspaceflight

Dear bakers, the judges would like you to decontaminate a parachute that will land on Mars. 🪂🔴 On your marks, get set… bake! 1️⃣ Place your parachute into an oven 2️⃣ Set the oven to 125°C for ~50 hours 3️⃣ When the centre of the parachute reaches 125°C, continue to bake for 36 hours

🌕 Electronics from moondust: a new ESA Discovery project led by the Danish Technological Institute is studying how lunar soil could be transformed into printable circuits, enabling in situ repair and manufacturing on the Moon. esa.int/Enabling_Suppo…

Congratulations, @esaspaceflight! 🌒🚀 Europe is proud to have enabled #Artemis II with the European Service Module (ESM) - delivering propulsion, power and life support for Orion and its crew. Built by European industry led by @AirbusSpace and monitored 24/7 by ESA teams, the ESM is a strong example of ESA technologies.

January–March 2026 was a busy season for us! Get up to speed on European space with our new ESA Impact visual report, out now 👉 esamultimedia.esa.int/multimedia/pub…
