As #Hera closes in on its destination, it will investigate the many mysteries left by #DART’s impact on Dimorphos. Why was the deflection so large? Where did all the dust come from? We also look forward to new insights from JAXA’s thermal infrared imager #TIRI. 🛰️
ESA's Hera spacecraft is nearing its destination; here are🔟asteroid mysteries that Hera will explore, including...
🤔Why was asteroid Dimorphos so strongly deflected by NASA's DART impact?
🤔Where did all its dust come from?
🤔What lies beneath its surface?
😲(#5 may surprise you!)

#Hera is nearing the Didymos-Dimorphos binary asteroid system and is expected to arrive around 4 November (JST) After the #DART impact, it will study the asteroids’ shapes, masses, rotations, and orbital dynamics. We look forward to more discoveries! 🚀✨

#Dragonfly, a rotorcraft mission to explore Saturn’s moon Titan, successfully completed a flight simulation! The mission demonstrated autonomous landing-site selection and touchdown. ISAS/JAXA is providing a seismometer to explore #Titan’s interior 👀.
NASA’s Dragonfly mission successfully completed its most comprehensive flight simulation yet at @JHUAPL, testing its ability to autonomously navigate and land safely on Saturn's moon Titan. 🚁

On the front line of planetary defense. #Hera has captured its first separate views of asteroids Didymos and Dimorphos! Detailed images of Dimorphos are set to be released on Nov. 25. JAXA's #TIRI thermal infrared camera is onboard to also studying the effects of the DART impact
Our Hera spacecraft can now see Didymos and Dimorphos as two separate asteroids!
Coming closer, it will study the effects of NASA's 2022 DART impact and help advance asteroid deflection as a planetary defence technique.
The first detailed images of Dimorphos are expected on 25 November.

The final countdown! 🎶 #RomanSpaceTelescope is on the final checks before science begins! Japan contributes coronagraph optical components, data reception at our Misasa station, and coordinated observations with the Subaru Telescope & PRIME. We can’t wait for the first images!🔭
It's the final countdown 🎶
We're one step closer to Roman's first images! The observatory is now fully functional and the team is performing their final checks and calibrations before starting science observations.

Thank you, @esascience, for sharing #MMXLIFTOFF and supporting the #MMX mission! 🚀 Together, Japan and Europe will explore Phobos and Deimos, return samples from Phobos, and help uncover the origins and evolution of our Solar System.
Next stop: Phobos & Deimos 🌑
MMX has successfully launched from Tanegashima, Japan. Its mission is to observe Mars’s mysterious moons, collect a sample from Phobos's surface and return it to Earth.
