small astronomy satellite a

Launched on this day in 1970, Uhuru (also known by the above designation) embarked on fourteen-month mission to perform a comprehensive scan of the entire sky in a first of its kind demonstration of x-ray astronomy. Scanning space for cosmic x-ray sources, Uhuru, among other achievements, identified the first strong candidate for the then theoretical black hole and triangulated an entire catalogue of extragalactic sources. The satellite was named after the Swahili word for freedom in recognition of the hospitality of Kenya, where the launch took place, from a former Italian operated off-shore oil platform converted into a spaceport near Mombasa and on the equator.
