STS-72, the 74th flight of the Space Shuttle program and the 10th of the orbiter Endeavour was launched at 4:41AM EST 11 January 1996 after a brief hold at the T−5-minute mark due to communication issues.
[2]: 3 The nighttime launch window was in support of the mission's primary objective, the capture and return to Earth of a Japanese microgravity research spacecraft known as Space Flyer Unit (SFU).
On flight day four, Wakata again operated Endeavour's robot arm to deploy the Spartan, sending the experiment-laden platform on its way to a 50-hour free-flight at a distance of approximately 45 miles (72 kilometers) from the orbiter.
After taking a few minutes to acclimate themselves in the payload bay, first-time spacewalkers Chiao and Barry attached a portable work platform to the end of the robot arm, operated by Pilot Brent Jett and Mission Specialist Koichi Wakata.
Jett used the arm to grapple various pieces of hardware designed to hold large modular components, mimicking the way equipment boxes and avionics gear will be moved back and forth in assembling the Space Station.
Chiao and Barry then unfolded a cable tray diagonally across the forward portion of the cargo bay housing simulated electrical and fluid lines similar to those which would later connect modules and nodes of the Space Station.
The result was a 90-minute documentary narrated by Bill Nye titled Astronauts which first aired on PBS on 17 July 1997 and was later released on VHS home video.
