The International Space Station was thrown briefly out of control on Thursday when jet thrusters of a newly arrived Russian research module inadvertently fired a few hours after it was docked to the orbiting outpost, NASA officials said.

The seven crew members aboard — two Russian cosmonauts, three NASA astronauts, a Japanese astronaut and a European space agency astronaut from France — were never in any immediate danger, according to NASA and Russian state-owned news agency RIA.

But the malfunction prompted NASA to postpone until at least Aug. 3 its planned launch of Boeing's new CST-100 Starliner capsule on an uncrewed test flight to the space station. The Starliner had been set to blast off atop an Atlas V rocket on Friday from the Kennedy Space Center in Florida.
