ESA’s solar eclipse-making Proba-3 mission is about to leave Europe, to head to its launch site in India. The mission’s two spacecraft – which will manoeuvre precisely in Earth orbit so that one casts a shadow onto the other – have departed the facilities of Redwire Space in Kruibeke, Belgium. The pair will be flown to the Satish Dhawan Space Centre, near Chennai, for the launch campaign to begin.
