The Ariel VI mission, known as UK6 prior to orbit, was launched from the Wallops Island Launch Center in the United States on 2 June 1979. The orbit obtained was a 600 km x 650 km elliptical orbit, at an inclination of 55 degrees.

Mission Characteristics

Lifetime
Jun 1979–Feb 1982
Special Features
Three scientific instruments, of which one was a cosmic-ray experiment and the other two were X-ray detectors. The scientific output of these experiments was severely limited by electromagnetic interference from ground-based radar hampering the pointing operations.

Payload

X-ray detectors

Energy Range
1–50 keV
Effective Area
∼300 cm2

X-ray collector system

Energy Range
0.25 keV
