"NASA Plans Another 1-Year Astronaut Mission: Timing Uncertain"

NASA is considering running more year-long astronaut missions following successful near-year-long planned missions aboard the International Space Station (ISS). The challenge is getting new spacecraft ready to support yearlong missions, with SpaceX and Boeing's vehicles being relatively new options for the 25-year-old ISS. The agency is accumulating years in orbit to prepare for long-duration space missions to more distant locales, including Artemis program missions to the moon later in the 2020s and human Mars missions. The ISS is currently approved to fly until 2030, providing six more years of opportunity to run longer missions than the usual six months each, but the timeline could potentially be extended.
