As of September 21, 2022, NASA has not made any conclusive statements regarding the potential extension of the two NASA astronauts' mission at the International Space Station (ISS) until next year. The final decision lies with NASA, in coordination with international partners and mission stakeholders.

NASA typically operates on a rotational basis, with astronauts spending an average of 6 months on the ISS before returning to Earth. However, due to various factors such as launch delays or logistical challenges, mission durations can be adjusted.

If there were a decision to extend the astronauts' stay, NASA would consider factors like the availability of resources, the overall health and safety of the crew, and the scientific and operational objectives of the mission. They would also coordinate closely with the international partners involved in the ISS program.

It's worth noting that the dynamic nature of space missions means that plans can change based on unforeseen circumstances. For the most up-to-date and accurate information, I recommend referring to official sources such as NASA's website or press releases.
