Understand

X-ray Multi-Mirror Mission (XMM-Newton) has been one of the most successful astronomy missions launched by the European Space Agency.

• It exploits innovative use of replication technology for the X-ray reflecting telescopes that has resulted in an unprecedented combination of effective area and resolution.
• Three telescopes are equipped with imaging cameras and spectrometers that operate simultaneously, together with a coaligned optical telescope.
• The key features of the payload are described, and the in-orbit performance and scientific achievements are summarised.
