Virgin Orbit and Rocket Lab teams are gearing up for their first missions of the year in the coming days, with Virgin’s air-launched rocket set for its second demonstration flight and Rocket Lab’s Electron booster poised to launch a small German-owned communications satellite.

Christopher Ferguson, commander of the final space shuttle flight and now a Boeing executive, has stepped down as commander of the first piloted test flight of the company’s troubled CST-100 Starliner commercial spacecraft, he and Boeing announced Wednesday. He has been replaced by NASA astronaut Barry “Butch” Wilmore.

The nearly $1.9 billion BepiColombo mission to Mercury jointly developed by the European Space Agency and the Japan Aerospace Exploration Agency lifted off Friday night from French Guiana aboard an Ariane 5 rocket. Launch occurred at 9:45 p.m. EDT Friday (0145 GMT Saturday).
