#OTD 10 years ago @ESA_Rosetta came to rest on comet 67P closing an extraordinary chapter of European exploration ☄️ Today @ESA_Hera is 330,000 km from Didymos — less than the distance from Earth to the Moon 🌍🌙 One journey ended. Another is about to begin. #Europe keeps daring

This is truly historic ! First time @esa and any space agency will stay several months studying a binary asteroid
ESA's Hera mission
@ESA_HeraOct 23
Hera’s second braking manoeuvre yesterday proved successful, reducing the spacecraft’s velocity relative to the Didymos and Dimorphos system by 70 m/s from a distance of 2300 km away. Some 90% of the 31-minute thruster firing took place in the early morning, followed by a cross-check of performance, with the remaining 10% occurring that afternoon. Hera is now moving at 20 m/s relative to the asteroids; a trio of smaller ‘transition’ manoeuvres this coming week will reduce Hera’s relative velocity down to near zero. hera.esa.int/

In @esa's Hera mission design, the small Juventas CubeSat carries radar to probe inside Dimorphos, while Hera relays its signals. Small spacecraft can take on specialized measurements. This is the planned investigation, not a completed map of the interior. esa.int/Space_Safety/Hera/He…

The European Space Agency's Hera mission is set to provide critical insights into planetary defense against asteroid threats. Experts involved in space, science, and culture have highlighted the importance of such missions in understanding our place in the universe.

🚀🇯🇵 C’est le grand jour pour MMX ! Le lanceur japonais H3 F10, emportant la sonde de la JAXA, décollera le 19 octobre à 21h41 (heure de Paris). Objectifs : rapporter des échantillons de Phobos, lune de Mars, et y déployer le rover européen Idefix. Une première mondiale !

That moment when the fairing leaves facilities to meet its launch vehicle is really emotional. Years of hard work, worries, failures, sleepless nights are all mixed with hope, excitement, and high pressure knowing a million things can go wrong. Per aspera, ad astra 🚀💪🏻

📣Launch announcement The Martian Moons eXploration (MMX) mission is set to launch on a H3 rocket from the Tanegashima Space Center at 21:41 CEST on 19 October 2026 👉esa.int/Science_Exploration/… 1/4
Infographic explaining the MMX mission (part 1) in the style of a comic strip. At the top we see several logos: ESA, JAXA, NASA, DLR and CNES. Below there are three panels showing a timeline of the mission: October 2026 launch, August 2027 arrival at Mars, September 2027 arrival at Phobos. Two other panels show the mission observing Phobos from orbit and scouting for a landing site for the rover and a sample retrieval sites, and the release of the Idefix rover.

Several panels show the mission collecting samples from Phobos, the return module separating from the exploration module, dropping a capsule over Australia and a scientist holding the samples. A last panel lists the scientific questions scientists hope to answer using the samples: 'Where did Mars's moons come from?', 'What can they tell us about habitability in the Solar System?', and 'How has Mars and its environment changed over time?'.
