Russian astronauts Oleg Kononenko and Nikolay Chub today marked the one year anniversary of their launch in 2023, thus marking another Russian yearlong mission in space.
The two cosmonauts were sent to the orbit aboard the Soyuz MS-24 manned spacecraft, which blasted off from the Baikonur space launch center on September 15, 2023. The third crew member on board was NASA astronaut Loral O’Hara, who returned to the Earth on April 6, 2024. Kononenko and Chub, as well as NASA astronaut Tracy Dyson, will travel back aboard the Soyuz MS-25 spacecraft, whose departure is scheduled for September 23.
Their return next week will not mark a record for the longest flight in space. That belongs to Valeri Polykov, who occupied the Soviet-built Mir space station in the mid-1990s for one year, two months, and two weeks in the mid-nineties, or 438 days. The second longest flight was by Sergey Avdeev, 380 days on Mir in 1998-1999, with the third longest flight by Sergey Prokopyev, Dmitry Petelin, and Franco Rubio, 371 days in 2022-2023.
When Kononenko and Chub return on September 23rd, their flight will 373 days long, passing the 2022-2023 mission.
Note that only one American is on this list. A few have flown almost a year, but only Rubio has made it, and that was forced on him unplanned because of problems with the Soyuz capsule that brought him into orbit. He was forced to stay up an extra six months and come down on the next Soyuz.
The reason for this lack of long American flights is entirely NASA’s fault. It has consistently resisted doing such long missions, even holding the Russians back during the first two decades of ISS’s operation. The Russians no longer follow NASA’s timidity, and have been doing more such missions, because such missions will be the only way to gather the necessary medical data needed for future missions to Mars.
Meanwhile, NASA hesitates, and sometimes touts eleven-month missions (such as Scott Kelly’s) as year-long missions, a blatant lie that our propaganda press repeats mindlessly. I fully expect the first planned year-long American mission will be done privately, outside of our government, once Starship begins flying regularly.
