New Ways to Deal With Astronauts' Health Challenges in Space Revealed

A team of psychologists has revealed new ways to deal with health challenges in space, in a research that is being hailed as groundbreaking one.

As NASA prepares to send humans back to the moon and then on to Mars, psychologists are exploring the challenges astronauts will face on missions that will be much longer and more demanding than previous space flights.

Psychologists said that longer missions mean astronauts will be faced with immense psychological pressures as they adjust to being so far away from Earth, which could lead to depression and interpersonal conflicts.

They have outlined these mental health challenges and introduced a new interactive computer program that will help address psychosocial challenges in space.

"Lessons learned from the past, research in extreme environments, training, conditioning, and countermeasures for psychological stress are some of the things NASA is in the process of addressing for the upcoming age of exploration," said psychologist Marc Shepanek, from the Office of the Chief Health and Medical Officer at NASA.

Historically, astronauts have been reluctant to admit to mental or behavioral health problems for fear of being grounded.

Psychologist James Carter, and his colleagues, are in the process of developing a suite of interactive computer programs, dubbed the Virtual Space Station, using input from 13 veteran long-duration NASA astronauts who have flown on the International Space Station, Mir and Skylab.

The system is being evaluated in a set of randomized controlled clinical trials.

This interactive program will help astronauts prevent, detect, assess and manage their own psychosocial problems. They will learn how to cope with depression and how to resolve conflicts with other astronauts.

"Behavioral health problems can interfere with the success of the mission, especially on long-duration space flights like missions to the International Space Station, the moon and Mars," said Carter.

"These self-guided software tools will provide private and immediate access to treatments even though the patient may be many miles from Earth," he added.

The Virtual Space Station has already been deployed in Antarctica.

However, as astronauts aim to explore a new planet, the one they leave behind could be foremost on their minds. They will have limited contact with their families and radio communications with Mission Control will be delayed, possibly for as long as 40 minutes.

In her presentation, family sociologist Phyllis Johnson, analyzed interviews with astronauts who had spent an extended amount of time in space.

The astronauts identified what they felt was the role of NASA, themselves and their families in creating a "home away from home" during their flights.

According to Johnson, "For example, they emphasized the importance of regular communication regarding work, publicity and education, all of which provide connection to Earth and helped to reduce the perception of isolation."
