BepiColombo mission is about to arrive at Mercury! It's a pretty nifty design: ESA's Mercury Planetary Orbiter (MPO) and JAXA's Mercury Magnetospheric Orbiter (Mio) are travelling to #Mercury as a compostive spacecraft, stacked on top of a transfer module. So separation & arrival will happen in stages. ▶️ https://www.esa.int/ESA_Multimedia/Images/2018/10/BepiColombo_arrival_at_Mercury_timeline?p Planetary science is a good reminder that science needs long-term planning and foresight. #BepiColombo was launched in 2018! #astrodon #space #ESA #JAXA #VicisAstro
