Being in space presents a host of unique challenges. Astronauts need to stay mentally well and focused to keep themselves, their crew and spacecraft safe, and achieve their mission objectives.

As we prepare to return to the Moon and eventually travel to Mars, the impact on astronauts' mental health will be even greater.

Environment

Living in a cramped environment without being able to go out for a walk can be draining. The constant fan noises, recycled air, limited privacy and overall lack of comfort add to the mental charge.

Overview effect

When astronauts first see our planet from space, it is a life-changing experience. This perspective leads to a greater appreciation for Earth and its fragility, and a deep connection to humanity as a whole.

Isolation

Astronauts often live and work in space for long periods with limited connection to family and friends. They share a small space with a handful of crewmates.

Delays and distance

Communications delays between space and Earth can be frustrating and affect operations. Astronauts can't return home quickly in case of emergency, and few resupply missions are possible.

Disrupted sleep cycle

A good night's sleep is crucial to staying healthy and performing well. Astronauts in space experience 16 sunrises and sunsets a day aboard the International Space Station, which can greatly affect their sleep patterns.

Performance and safety

Space is a dangerous place where tasks that would be simple on Earth become more complex. Astronauts have lots of work to do and are required to be productive. Sometimes, they need to make life or death decisions with limited information.
