At 4:43 PM, EDT, the Soyuz 34 Capsule was launched from the Baikonur Cosmodrome in Kazahkstan, carrying a three-man crew. Six hours later they docked with the ISS, forty-two hours ahead of schedule.
The Soyuz 34’s record-setting pace depended on a strategic launch time, lifting off just as the ISS passed over the Baikonur Cosmodrome. Still, by the time the capsule had cleared Earth’s atmosphere, the station had a thousand mile head start. To make up the difference the Soyuz 34 made a series of carefully calculated engine burns to regulate its speed, trajectory, and orientation using newly upgraded thrusters controlled by an improved maneuvering system.
For the next 6 months, the Soyuz 34’s crew will be guests on the ISS. After completing their scientific missions, the three astronauts will return to Earth using the same capsule.
