NASA Administrator Jim Bridenstine said this week the space agency is not unduly delaying the debut of new SpaceX and Boeing commercial crew capsules as engineers gear up for a challenging rapid-fire sequence of test flights in the next few months, all against the backdrop of in-depth safety reviews before clearing the privately-owned ships to carry astronauts.

A day after launching from the Kennedy Space Center, NASA astronauts Doug Hurley and Bob Behnken docked with the International Space Station aboard SpaceX’s Crew Dragon spacecraft at 10:16 a.m. EDT (1416 GMT) Sunday to complete a 19-hour transit on the new commercial crew capsule.

Seven astronauts and cosmonauts are gearing up for launches April 9 and April 22 to the International Space Station, replacing seven outgoing crew members set to land in Kazakhstan and off the coast of Florida on April 17 and April 28.
