NASA launches Space Shuttle Endeavour on a mission lasting almost ten days to test the SPACEHAB pressurized lab module. A long-term exposure experiment is retrieved for ESA, though a spacewalk must be undertaken when its antennae fail to stow themselves away automatically for insertion into the cargo bay. Aboard Endeavour for her fourth flight into orbit are Commander Ronald Grabe, Pilot Brian Duffy, Payload Commander G. David Low, and mission specialists Nancy Sherlock, Peter Wisoff and Janice Voss.
