At two hours into the mission, the payload doors opened and the astronauts prepared to deploy the Chandra X-ray Observatory. For six hours, while Columbia silently orbited Earth, all the systems on the Chandra spacecraft were checked out and the satellite reached equilibrium with the conditions in space.
Solar and Heliospheric Observatory: Solar and Heliospheric Observatory (SOHO), satellite managed jointly by the European Space Agency (ESA) and the U.S. National Aeronautics and Space Administration (NASA) that is equipped with a battery of novel instruments to study the Sun. SOHO was launched by NASA on an Atlas rocket on Dec. 2, 1995. In order to provide continuous observations, it was maneuvered to orbit the first Lagrangian point (L1), a point some 1.5 million km (900,000 miles) from Earth toward the Sun where the gravitational attraction of Earth and the Sun combine in such a way that a small body remains approximately at rest relative to both.
