The countdown is on! 🛰️
The MMX space probe is now complete, with the Idefix rover mounted and ready for launch towards the Mars system.
JAXA recently unveiled the finished spacecraft to the public at the Tanegashima Space Center in Japan, ahead of final preparations for mounting it onto the launch rocket.
Idefix, built together by DLR and CNES, is clearly visible here in its travel position between the probe's landing legs. 🤏 Roughly the size of a crate of drinks, it weighs just 25 kilograms.
Around the turn of 2028/2029, the MMX mothership will release the rover into free fall towards Phobos, from a height of approximately 40 metres above the surface.
Once it lands, Idefix will make history as the first wheeled rover to drive on a celestial body with such extremely low gravity – less than a thousandth of Earth’s.
The MMX mission is scheduled to launch on 19 October 2026 at 21:41 CEST. 🚀
