Q&A with Michel Denis, ExoMars flight director

SpaceX’s Falcon 9 rocket and Crew Dragon Endeavour spacecraft rolled out to pad 39A at NASA’s Kennedy Space Center on Friday. Hydraulics raised the 215-foot-tall rocket vertical on the historic launch pad in preparation for liftoff with four astronauts heading for the International Space Station.

Europe’s Galileo navigation program turned to the workhorse Ariane 5 rocket for a heavy lift Thursday, delivering four new satellites to orbit on the launcher’s 75th successful flight in a row and pushing the growing fleet closer to global coverage.

Two more Galileo satellites successfully catapulted into space from the French Guiana jungle aboard a Soyuz rocket Tuesday, putting Europe’s multibillion-dollar navigation system on track to begin limited global service later this year.
