Novae and supernovae play a key role in many fields of Astrophysics and Cosmology. Despite their importance, an accurate description of which objects explode and why and how they explode is still lacking. One of the main characteristics of such explosions is that they are the main suppliers of newly synthesized chemical elements in the Galaxy. Since some of these isotopes are radioactive, it is possible to use the corresponding gamma-rays as a diagnostic tool of the explosion thanks to their independence on the thermal state of the debris. The drawback is the poor sensitivity of detectors in the MeV energy domain. As a consequence, the radioactive lines have only been detected in one core collapse supernova (SN 1987A), one Type Ia supernova (SN 2014J), and one supernova remnant (Cas A). Nevertheless these observations have provided and are providing important information about the explosion mechanisms. Unfortunately, novae are still eluding detection. These results emphasize the necessity to place as soon as possible a new instrument in orbit with enough sensitivity to notice-

“…The main achievement of the observatory was the discovery and study of the hard Xray emission from Supernova 1987A. But it also contributed a lot in broad-band X-ray spectroscopy of black hole transients (X-ray novae) and X-ray imaging of the Galactic center field (Sunyaev et al, 1990a).…”

“…The Röntgen X-ray observatory was launched in 1987 aboard the Kvant module which docked to the MIR space station. The complement of detectors [127] included a sensitive high energy 15-200 keV X-ray experiment (HEXE, [128]), a codedmask system for imaging high-energy photons (TTM, [129]), and a gas scintillation proportional counters (GSPC, [130]). It also carried two gamma-ray experiments, which reached down to 30-40 keV [127].…”

In this chapter we briefly review the history of X-ray Astronomy through its missions. We follow a temporal development, from the first instruments onboard rockets and balloons to the most recent and complex space missions. We intend to provide the reader with detailed information and references on the many missions and instruments that have contributed to the success of the exploration of the Xray Universe. We have not included missions that are still operating, providing the world-wide community with high quality observations. Specific chapters for these missions are included in a dedicated section of the handbook.
