These are the missions that we use in research into high energy astrophysics.
The X-ray Multi-Mirror Mission (XMM) is an observatory developed by the European Space Agency (ESA) and will provide X-ray images and spectra for the world community. XMM will be used to probe very hot plasmas (temperatures in the range of millions to hundreds of millions of degrees).
The Swift observatory is one of NASA's Explorer missions, and is designed to locate and study one of the most intense explosions in the universe, Gamma Ray Bursts (GRBs). These bursts occur randomly across the sky and can last from a few seconds to more than a minute.
INTEGRAL is the European Space Agency's INTErnational Gamma-Ray Astrophysics Laboratory satellite. Its mission is to observe objects producing the most energetic radiation in the Universe and it will help to solve some of the biggest mysteries in Astronomy.
Athena – Advanced Telescope for High-ENergy Astrophysics – will be an X-ray telescope designed to answer two key astrophysical quetions: how does ordinary matter assemble into the large-scale structures we see today and how do black holes grow and shape the Universe?
