The Einstein Probe (EP), launched successfully on January 9, 2024, is a space mission dedicated to X-ray time-domain astrophysics with a broad range of scientific goals. EP carries a wide-field X-ray telescope to monitor the soft X-ray sky in 0.5–4 keV with a 3600 square-degree field-of-view and a narrow-field X-ray telescope for follow-up observations in 0.3–10 keV and precise source locating. The satellite is currently in the commissioning phase, undertaking in-orbit tests and calibration of the spacecraft and payloads, and tests for the data telemetry and space-ground communication. The test and calibration results achieved so far show that the spacecraft and instruments are working normally, and all the performances meet the requirements of the project design. EP is expected to start normal science operations from late June or early July, 2024.
The enhanced x-ray timing and polarimetry mission (eXTP) is a flagship observatory for x-ray timing, spectroscopy and polarimetry developed by an international consortium. Thanks to its very large collecting area, good spectral resolution and unprecedented polarimetry capabilities, eXTP will explore the properties of matter and the propagation of light in the most extreme conditions found in the universe. eXTP will, in addition, be a powerful x-ray observatory. The mission will continuously monitor the x-ray sky, and will enable multi-wavelength and multi-messenger studies. The mission is currently in phase B, which will be completed in the middle of 2022.
The Hard X-ray Modulation Telescope (Insight-HXMT) was successfully launched on June 15th, 2017. It performs broad band X-ray scan survey of the Galactic Plane to detect new black holes and other objects in active states. It also observes X-ray binaries to study their X-ray variabilities. Here we will introduce the Science Operations of Insight-HXMT, which is responsible for collecting and evaluating observation proposals, scheduling observations, and monitoring the working status of the payloads
The Hard X-ray Modulation Telescope (HXMT or also dubbed as Insight-HXMT) is China’s first astronomical satellite. It was launched on 15th June 2017 in JiuQuan, China and is currently in service smoothly. It was designed to perform pointing, scanning and gamma-ray burst (GRB) observations and, based on the Direct Demodulation Method (DDM), the image of the scanned sky region can be reconstructed. Here we introduce the mission and its progresses in aspects of payload, core sciences, ground calibration/facility, ground segment, data archive, software, in-orbit performance, calibration, background model, observations and preliminary results.
