Phrase: XMM-Newton mission | Statement: [ESA Horizon 2000 programme, notableWork, XMM-Newton mission]

Target entity: XMM-Newton mission
Context triple: [ESA Horizon 2000 programme, notableWork, XMM-Newton mission]

• A. Einstein Observatory
  The Einstein Observatory was NASA’s first fully imaging X-ray telescope in space, pioneering high-resolution X-ray astronomy of cosmic sources.
• B. Chandra X-ray Observatory
  The Chandra X-ray Observatory is a space-based telescope that observes high-energy X-ray emissions from hot regions of the universe, such as exploded stars, galaxy clusters, and matter around black holes.
• C. RXTE
  RXTE (Rossi X-ray Timing Explorer) was a NASA satellite observatory dedicated to studying time-variable X-ray sources such as neutron stars, black holes, and active galactic nuclei.
• D. Uhuru X-ray satellite
  The Uhuru X-ray satellite was the first Earth-orbiting mission dedicated to X-ray astronomy, pioneering the systematic study of cosmic X-ray sources and laying the foundation for modern high-energy astrophysics.
• E. Spektr-RG observatory
  The Spektr-RG observatory is a Russian-German space telescope mission designed to conduct an all-sky X-ray survey, particularly focused on studying galaxy clusters, black holes, and other high-energy cosmic phenomena.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.
