Why Can't the Russians Bring Back the Stranded American Astronauts?

The ongoing situation with the American astronauts astronaut Dyson and Williams stranded on the International Space Station (ISS) has garnered significant attention. The issue arises from the constraints of the Russian Soyuz capsule, which has limited seating capacity and operational protocol. This article explains the reasons behind this situation and the ongoing efforts to ensure the safe return of these astronauts.

Current Constraints and Protocols

The Russian Soyuz capsule, as of now, is already carrying three astronauts: Nikolai Chub, Oleg Kononenko, and Tracy Dyson. NASA and Roscosmos, the Russian space agency, follow a strict policy for arrivals and departures to the ISS, which is planned well in advance. This means that it is not possible to open up additional seats for the American astronauts immediately.

No Extra Capacity

The current transport vehicle being considered is a Progress cargo vehicle, which does not have the necessary life support or heat shield and is designed to burn up during re-entry. It is not meant for human transport and thus cannot be used to bring the astronauts back. Additionally, the Soyuz capsule has a capacity of three seats, and there are no extra seats available for the two American astronauts.

Upcoming Solutions

The situation will be resolved in February 2025, when the American astronauts will return to Earth aboard a SpaceX Dragon spacecraft. This vehicle is capable of carrying four astronauts, providing much-needed relief to the current seating constraints. Until that time, the astronauts will continue to perform their duties at the ISS, which include maintaining the station's operations and conducting scientific experiments.

Role of SpaceX

SpaceX has significantly changed the landscape of space transportation, making it a more affordable and reliable option. In the past, before SpaceX began manned flights, the cost of a seat on a Russian Soyuz capsule was as high as $90 million. Today, that price has dropped to approximately $55 million per seat, making SpaceX a much more feasible solution for NASA's needs.

Addressing Misconceptions

Some have speculated that the situation with the American astronauts will lead to a conflict with Russia. However, the current embargo and strained relations between the US and Russia do not extend to their space programs. The US and Russia collaborate on many space projects, including the ISS, and this cooperation remains intact despite political tensions. Therefore, the focus remains on ensuring the safe and controlled return of the astronauts.

Future of Astronaut Rotation

The upcoming use of the SpaceX Dragon for astronaut rotation to and from the ISS marks a significant shift in the way space agencies manage astronaut transit. It showcases the progress in commercial space ventures and the potential for cost-effective and efficient space travel.

In summary, the constraints of the Soyuz capsule and the tightly scheduled nature of ISS operations are the primary reasons why the Russian space agency cannot bring back the stranded American astronauts immediately. The upcoming use of SpaceX's Dragon spacecraft in 2025 provides a solution that is both feasible and efficient. The collaboration between space agencies continues, ensuring a smooth return for the astronauts and safeguarding the ongoing success of the ISS.
