They made a number of ultraviolet observations and provided learning experiences for the manufacture and launch of future space observatories.

The objectives were to make ultraviolet observations of deep space or nearby galaxies.

He has used optical, X-ray, radio, infrared and ultraviolet observations to understand how the transformations of galaxies are related to their local and global environment.

Secondary objectives of the mission include studies of the effects of weightlessness on living tissues and ultraviolet observations of stars.

In January 1974, Mariner 10 made ultraviolet observations of Comet Kohoutek.

Since the Shuttle could be oriented in only one direction at a time, X-ray observations had to be coordinated carefully with ultraviolet observations.

The orbiting Hubble telescope is designed for optical and ultraviolet observations.

Mariner 10's ultraviolet observations have established an upper bound on the exospheric surface density at about 10 particles per cubic centimeter.

It also makes ultraviolet observations not at all possible from Earth.

It was optimized for visible and ultraviolet light observations of variable stars and other astronomical objects varying in brightness.
