Rocket launches to be grounded while mid-air failure is investigated

Problem with Soyuz's thrusters must be identified before space flights can resume, say experts

The Russian Soyuz rocket that launches astronauts to the International Space Station will be grounded for months after two crew members were forced to make an emergency landing in Kazakhstan.

American Nick Hague and Alexey Ovchinin from Russia were aboard the Soyuz rocket when it developed a thruster problem nearly two minutes after takeoff and were forced to make an emergency landing in their capsule. The Russian space agency, Roscosmos, announced an immediate investigation into the incident.
