## Executive Summary
Astronauts return to Earth temporarily taller than when they left, as microgravity causes the human spine to lengthen by up to five centimetres.

## Intelligence Brief
Returning astronauts face a body that may feel like a betrayal, starting with a spine that has lengthened in microgravity. This growth means they come home taller than when they departed, though gravity compresses the spinal column again within days of landing. Some returning from 241 days aboard the ISS must even relearn how to walk.


Space Daily reports that this physical shift is part of a broader impact on the body. Other physiological changes include effects on the blood, eyes, and bone density. An Iowa State University lab is currently examining how muscle and bone deteriorate both in space and on Earth to better understand these shifts.


While the immediate spinal compression is documented, the long-term effects on the body's overall stability and the recovery process for those spending a year in space remain the central focus of inquiry.

## Verified Facts & Key Claims
### How much does the spine lengthen in space?
In microgravity, the human spine can lengthen by as much as five centimetres.

### How long does the increased height last after landing?
The height increase is temporary, as gravity compresses the spinal column again within days of returning to Earth.

### What other bodily systems are affected by space travel?
According to coverage, space travel affects the bones, blood, eyes, and muscles.
