New Satellite XRISM Launching to Study Cosmic Objects
Japan’s Tanegashima Space Center is preparing to launch a new satellite, XRISM, on August 25. The mission’s main objective is to study massive cosmic objects, using instruments specifically designed to measure the heat of a single X-ray photon. This groundbreaking technology will allow for detailed analysis of X-rays and provide valuable insights into the mysteries of the universe.
One of the key features of XRISM is its wide field-of-view instrument, which is the largest ever implemented in this type of imaging probe. This instrument will separate high-energy light into an X-ray rainbow, enabling researchers to precisely examine X-rays. The satellite is being led by the Japan Aerospace Exploration Agency (JAXA) in collaboration with NASA, the Canadian Space Agency, and the European Space Agency.
XRISM will explore various phenomena, including the internal structures of neutron stars, near-light-speed particle jets emanating from black holes in active galaxies, and the effects of extreme gravity on matter. To accomplish these tasks, the satellite will employ a spectrometer called Resolve, which can absorb a singular X-ray photon in each of its 6-by-6-pixel detectors.
Maintaining the necessary conditions for accurate measurements is essential for XRISM’s success. The spectrometer’s housing must be chilled to super-cold temperatures near absolute zero, which is achieved by using liquid helium. Additionally, XRISM will feature an instrument called Xtend, which will enlarge Resolve’s field of view, allowing for images within an area 60 percent bigger than a full moon.
Both Resolve and Xtend will utilize twin X-ray mirror assemblies developed at NASA’s Goddard Space Flight Center. These state-of-the-art mirrors are crucial for capturing the X-ray photons emitted by cosmic objects accurately.
With the launch of XRISM, scientists are eagerly looking forward to new discoveries and a better understanding of cosmic objects. The satellite’s advanced instruments and international collaboration promise to take our knowledge of the universe to new heights. Keep an eye on the skies for updates on XRISM’s mission and exciting findings from its cosmic exploration.
