Recent controversies over alcohol use among NASA astronauts and the case of Lisa Nowak, who was charged with attempted murder in February, have brought the issue of stress in space to the fore.

NASA is testing a handheld device that could help. It is designed to warn an astronaut if they are in an unfit condition to perform critical procedures like a spacewalk or a shuttle docking.

The device gives a person a three-minute test that involves pressing a button as quickly as possible after a light flashes. The test detects the cognitive deterioration caused by a lack of sleep or by stress, something that may be less apparent to the person taking the test.
