Norishige Kanai was concerned when he appeared to grow over 3 inches in space.
After Norishige Kanai, a Japanese astronaut, initially measured over 3 inches taller since arriving in space, he worried he wouldn’t be able to return home.
Kanai, who arrived at the ISS on Dec. 19, according to a press release, first posted on Twitter that he thought he’d grown more than 3.5 inches in the three weeks since his arrival at the International Space Station.
?????????????????????????????????????????????????????????????????????????
????????9cm?????????????????????????????????????????182cm?????+2cm????
In his tweet, Kanai said the crew had their bodies measured after reaching space and initial measurements put him at over 3.5 inches taller than on Earth, making the astronaut fearful because the Soyuz spacecraft he needs to use to come home has a height limit.
However, Kanai re-measured himself and, in a follow-up tweet, said he came in at a much more normal 0.
