A NASA astronaut and two Russian cosmonauts will launch to space later today (Sept. 15), and you can watch live.
NASA astronaut Loral O’Hara, alongside Russian counterparts Oleg Kononenko and Nikolai Chub, will launch aboard a Soyuz spacecraft to the International Space Station. Launch is scheduled for 11:30 a.m. EDT (1530 GMT or 8:30 p.m. local time at the Baikonur Cosmodrome in Kazakhstan.)
You can watch the launch live here at Space.com, courtesy of NASA Television. Coverage starts about 45 minutes before launch. The crew will then make one of the fastest-ever trips to the ISS, potentially arriving as soon as 2:56 p.m. EDT (1856 GMT). We will also carry that coverage live, from NASA. Hatch opening will follow around 4:45 p.m. EDT (2045 GMT) as the Soyuz astronauts join the Expedition 69 crew already on station.
The trio will launch aboard the MS-24 spacecraft as a relief crew for NASA astronaut Frank Rubio and Roscosmos‘ Sergey Prokopyev and Dmitry Petelin. Rubio and his colleagues were already scheduled for a six-month mission, which was delayed to a year following a leak in their own Soyuz spacecraft (MS-22) in December 2022.
The agencies eventually decided to rapidly send up an empty replacement vehicle, MS-23, which safely arrived in February. But prior to the leak, MS-23 was supposed to hold O’Hara and her relief crew, who were still in training at the time of its faster-than-expected launch. For Rubio and his crewmates, coming home required an even longer wait until the new MS-24 and O’Hara’s crew would be ready this month to relieve them.
In the meantime, Rubio, Prokopyev and Petelin unintentionally set records. At an expected 371 days in space (assuming a Sept. 27 landing), they are the first crew to spend more than a year on the ISS. And only four people have spent longer in space than that, all cosmonauts who visited the Soviet-era Mir space station for as long as 427 days.
