Three people will launch on a speedy trip to their orbital destination on a Russian spacecraft today (Sept. 21), and you can watch the whole thing live.
NASA astronaut Frank Rubio and Roscosmos cosmonauts Sergey Prokopyev and Dmitri Petelin are expected to launch to the International Space Station today from the Russian-run Baikonur Cosmodrome in Kazakhstan at 9:54 a.m. EDT (1354 GMT or 6:54 p.m. local time in Baikonur.)
Coverage will start at 9 a.m. EDT (1300 GMT) here at Space.com, via NASA Television, which is also available directly from NASA (opens in new tab). The agency will also carry coverage on its app, social media and website.

The Soyuz spacecraft from Russia’s federal space agency, known as Roscosmos, will take just two orbits and three hours to reach the ISS. The Soyuz will then dock with the orbiting complex, and, roughly two hours later, the hatches connecting the two spacecraft will open and the Soyuz crew will join Expedition 67.
Already on board the ISS are Expedition 67 commander and Roscosmos cosmonaut Oleg Artemyev, cosmonauts Denis Matveev and Sergey Korsakov, NASA astronauts Bob Hines, Kjell Lindgren, and Jessica Watkins, and European Space Agency astronaut Samantha Cristoforetti.
The Soyuz ride of Rubio, Prokopyev, and Petelin will mark the beginning of their six-month space mission. This will be Prokopyev’s second spaceflight and the first for Rubio and Petelin.
While NASA handles most of its ISS personnel needs through SpaceX commercial crew contracts, occasionally the agency tasks Roscosmos with bringing its astronauts aloft for logistical reasons (as there are only so many SpaceX flights available) and international exchange purposes.
And next month, a cosmonaut is scheduled to fly to the ISS with SpaceX for the first time: Anna Kikina is a member of SpaceX’s Crew-5 mission for NASA, which is scheduled to lift off on Oct. 3.

Boeing hopes to have its Starliner spacecraft ready in 2023 for more astronaut taxi trips. NASA has emphasized ISS relations remain normal despite Russia’s ongoing invasion of Ukraine, which started in February 2022.
