🛰️🪨After 2 years in deep space, ESA's Hera mission for planetary defence is closing in on its target - Dimorphos, the 1st object in the Solar System to have had its orbit changed by human action, when NASA's DART impacted it in 2022

At last ESA's Hera spacecraft for planetary defence has come close enough to resolve both bodies in the Didymos binary asteroid system separately - the smaller one was deflected by NASA's DART back in 2022 esa.int/Space_Safety/Hera/Fi…

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/

📣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?'.
