ESA's Hera mission

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…

@NASAJPL @NASAMars Congratulations to @NASA's @MissionToPsyche spacecraft for their successful flyby of Mars! It brought back happy memories of ours, last year esa.int/Space_Safety/H…

Hello Mars, goodbye Mars 👋 NASA’s #MissionToPsyche spacecraft was speeding by the Red Planet on May 15 when it snapped this rare, crescent view of Mars. The successful flyby flung the Psyche spacecraft toward its final destination: the metal-rich asteroid Psyche. 1/2

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

Hera is part of ESA's Space Safety programme, protecting our planet, people & infrastructure from space hazards. 🚨Last call! 🚨On 16 June our Space Safety Industry Day at #ESTEC in 🇳🇱 shares how European industry can partner in our work - come join us! 👉 indico.esa.int/event/646/over…

A successful deep-space manoeuvre has put ESA’s Hera spacecraft on course for arrival at the Didymos binary asteroid system later this year! At Didymos, Hera will help turn asteroid deflection into a reliable technique for protecting Earth 🛡️🌍 esa.int/Space_Safety/H…

Surprising new study on @NASA's DART mission collision in 2022: not only did it change the orbit of the smaller Dimorphos asteroid, but it also shifted the solar orbit of its parent body Didymos. Hera's arrival this autumn will reveal more: nasa.gov/missions/dart/…

One year ago #HeraMission was stranded on Earth, its launcher grounded, as a hurricane closed in on its launch site. 12 months later sees it cruising on the far side of the Sun. Learn the story of Hera in space: esa.int/ESA_Multimedia…

ESA welcomes JAXA's interest in participating in the Ramses mission to the asteroid Apophis, which will make a safe but exceptionally rare and scientifically valuable flyby of Earth in April 2029. esa.int/Space_Safety/P…

Hera's team @esaoperations used the spacecraft to observe two asteroids at short notice. This is a hot topic, as scientists discuss the possibility of using existing spacecraft to observe high-priority, deep-space objects like 2024 YR4 or 3I/ATLAS. Asteroid (1126) Otero 👇

ESA's Hera mission has spotted its first asteroids! Hera is on the way to the Didymos binary asteroid system to explore the aftermath of humankind's first attempt to move an asteroid. Though faint, these observations are very encouraging for the performance of Hera's camera.

ESA's astronomers are actively tracking 3I/ATLAS, which is now the third confirmed interstellar comet to pass through our Solar System! More info at: esa.int/Space_Safety/P…

Astronomers may have just discovered the third interstellar object passing through the Solar System! ESA’s Planetary Defenders are observing the object, provisionally known as #A11pl3Z, right now using telescopes around the world.

"Every time we have interacted with an asteroid, the reaction has been totally different from what we expected." Check out the replay from Saturday's @AsteroidDay Festival, featuring great speakers from @ESA_Hera, @VirtualTelescop and @NASAJPL! youtube.com/live/HI5RQeVbL…

Today, we are at the @AsteroidDay Festival in Luxembourg to share the excitement of ESA's Planetary Defence activities with visitors of all ages! Come and visit us at the ESA stand, or follow the event online at: youtube.com/watch?v=HI5RQe… Event programme: asteroidday.org/events-in-luxe…

All aboard for asteroid Apophis! ESA's Ramses mission aims to rendezvous with the asteroid Apophis as it passes Earth in 2029. Ramses will deploy a CubeSat led by @emxys just a few kilometres from the surface of the asteroid to study it up close. esa.int/Space_Safety/P…
