description Overview

COBE

The COBE (Cosmic Background Explorer) mission, operated by NASA from 1989 to 1993, provided crucial data about the early universe. It precisely measured the cosmic microwave background radiation—the afterglow of the Big Bang—and identified subtle temperature variations within it. These anisotropies offered invaluable insights into the formation of large-scale structures in the cosmos. The observat...

Its working mission continued until 1972, using an orbital viewpoint to map the surface and investigate the planet's physical features. A major dust storm initially obscured much of Mars, so observations had to wait for clearer views before the spacecraft could carry out much of its mapp...
