STS -8 was the first flight of a space shuttle, in which both the start and landing are done at night. The launch took place due to the weather with 17 minutes delay.
The payload was essentially the Indian multi-purpose Satellite Insat 1-B. There have also been stress testing the shuttle itself. The cockpit of the shuttle faces away from the sun is kept for 14 h, so as to examine the influence of the intense cold of the life support systems.
Also, various research experiments have been performed. Inter alia the behavior of six rats in microgravity was examined.
With Guion Bluford was the first time in NASA's history an African American into space.
