On 3 January 2012, one of the most productive X-ray observatories of all time ceased its science operations. The Rossi X-ray Timing Explorer (RXTE) observed the high-energy cosmos for 16 years. During that time RXTE made a host of discoveries, and its results were used in about 2000 refereed publications. My favourite Rossi finding? The discovery of a black hole with a mass just 3.8 times that of the Sun!
