Japanese astronaut sorry for 9cm ISS growth mistake

A Japanese Astronaut has gained more than a few centimeters while spending time on the International Space Station, and is now anxious he might not be able to return home due to his growth in space. We had our bodies measured after reaching space, and wow, wow, wow, I had actually grown by as much as 9cm!

Norishige Kanai told his social media followers on Twitter that he is now anxious he might not fit into the seat of the Russian Soyuz vehicle that is due to bring him home in June. "I am a bit anxious whether my body will fit in the return Soyuz seat".

The Soyuz MS-07 spacecraft carrying the crew to the International Space Station from the launchpad at the Baikonur Cosmodrome, Kazakhstan December 17, 2017.

NASA scientists say astronauts can grow up to three percent taller while in space or around five centimetres for someone 1.8 metres high.

It is the first space mission for Kanai, who previously served as a diving medical officer with the Japan Maritime Self-Defense Force.

The news of a Japanese astronaut who shot up nine centimetres in height after just a month in spaceflight turned out to be too out-of-this-world to be true.

The absence of gravity allows the vertebrae in the spine to spread apart in order to grow in height or stretch out.

When asked if Kanai should be concerned about making it back to Earth, Anderson said he is not anxious because once you return to Earth your spine shrinks back to normal.

Astronauts are tightly measured for their placement in the Soyuz capsules which return them to Earth.

"According to my quick calculations here, I seem to have grown about an inch or so", formerly 191 centimetres-tall astronaut Richard Hieb told controllers in 1994. A growth of a couple of centimeters might be tolerated, but a growth of 9cm could pose a problem.
