Topped with the Russian Progress 69 cargo resupply ship, the Soyuz will lift off from the Baikonur Cosmodrome in Kazakhstan at 3:58 a.m. EST (0858 GMT). The Progress spacecraft will then dock at the International Space Station at 7:24 a.m. EST (1224 GMT), completing the rendezvous in a record time of 3 hours and 26 minutes.

Russia's space agency, Roscosmos, planned to debut this new fast-track route to the ISS with its last cargo launch of the Progress 68 spacecraft, in October. But a last-minute delay forced the agency to resort to the old two-day rendezvous due to the orbital mechanics involved with reaching the ISS. Postponing that launch meant that Roscosmos missed the launch window to try out the new, shorter rendezvous, NASA officials said.
"If any technical issues are identified by Russian flight controllers in the early stage of the flight, the spacecraft will be capable of defaulting to a standard, two-day rendezvous profile," NASA officials said in a statement.

In 2013, the agency cut the two-day travel time to just 6 hours for both Progress and Soyuz capsules, making the cramped crewed flights to the ISS a little more bearable for the astronauts and cosmonauts on board.
This uncrewed cargo mission will deliver 3 tons of food, fuel and other supplies to the Expedition 54 crew, NASA officials said. The record-breaking flight comes just one week after the two Russian crewmembers at the ISS, Alexander Misurkin and Anton Shkaplerov, set a record for the longest Russian spacewalk.
