An expert warns that astronauts stuck in space might face an oxygen shortage within 96 hours if problems occur.

Recently, an expert has raised concerns about a potential oxygen shortage for astronauts who might be stranded in space.

The warning suggests that astronauts could face a critical situation where they have only 96 hours of breathable oxygen left if they become stuck.

Expert warns astronauts stuck in space could face oxygen shortage in 96 hours

Sunita Williams and Butch Wilmore, two American astronauts, began their space journey on June 5 with plans for a short stay.

However, technical difficulties with the Boeing Starliner spacecraft have unexpectedly extended their time in space.

Williams and Wilmore initially expected to return to Earth within a week.

However, they have now been aboard the International Space Station for over two months.

NASA recently updated that both astronauts are in good spirits.

They are also staying busy with various activities while onboard the ISS.

Possible risks and scenarios for astronauts’ return

There is a possibility that the astronauts might stay for up to eight months.

This depends on whether a SpaceX craft or the Boeing Starliner is available for their return.

Rudy Ridolfi, a former commander of US military space systems, highlighted the importance of proper alignment of the Starliner’s service module for safe re-entry.

He described three severe scenarios that could occur if the alignment is incorrect.

Ridolfi’s most alarming scenario involves the Starliner re-entering at the wrong angle.

This could cause the craft to bounce off the Earth’s atmosphere and stay in orbit.

This outcome could result in the spacecraft being stranded in space with malfunctioning thrusters and only 96 hours’ worth of oxygen remaining on board.

Potential risks of starliner re-entry and NASA’s plan for safe return

Additionally, a faulty alignment could prevent the Starliner from re-entering the Earth’s atmosphere.

This would leave the spacecraft drifting in space indefinitely.

In the gravest scenario, a re-entry angle that is too steep could create extreme heat and friction on the craft’s heat shield.

This may cause the shield to fail and the spacecraft to burn up upon re-entry.

These possible scenarios show how serious the situation is for the astronauts.

NASA is working to find the safest way to bring Williams and Wilmore back before the end of August.
