The Nuclear Spectroscopic Telescope Array (NuSTAR) is a small NASA mission launched on 13th June 2012 into a low Earth orbit. It observes in the 3-79 keV range. It has two focal plane detectors of 13’ x 13’, with spectral...
Integral was a European Space Agency mission that was active between 17 October 2002 and 28th February 2025. It functioned in a highly elliptical orbit with observations of ~50 h possible. The four onboard instruments were SPI, a gamma-ray spectrograph...
The Neutron star Interior Composition Explorer (NASA) mission was launched on the 3rd June 2017 and installed on the International Space Station in low Earth orbit. This instrument observes in the 0.2-12;0 keV band and reaches ~3 x 10⁻¹⁴ erg...
The X-Ray Imaging and Spectroscopy Mission (XRISM) is a JAXA/NASA collaborative mission, with ESA participation. XRISM was launched on September 7, 2023 into a low Earth orbit. The XRISM payload consists of two instruments: Resolve provides non-dispersive 5-7 eV...
Swift was launched by NASA on 20th November 2004 in a low Earth orbit which allows for roughly hour long observations of a source. The Burst Alert telescope observes in the 15-150 keV domain down to a sensitivity of ~1 …
