It had a radiation detector, an X-ray crystallographer, and a complete weather station.

When we talk about telescopes, we're usually referring to devices that "see" the visual spectrum of light, but astronomers also build telescopes that gather radiation like radio waves and X rays in order to peer deep into outer space.
