Try 1: put it on the Advanced X-ray Astrophysics Facility (early 1990s). There have been many attempts to do orbital astronomy with this device, and so far all have them have failed due to no fault of the device itself. In an August 27 thread on X, McDowell also known for his Jonathan’s Space Report website, explained the long, complicated history of attempts to launch a microcalorimeter. XRISM is “pioneering the microcalorimeter technology” that will be used on future X-ray observatories, McDowell adds, measuring “the velocity, temperature and composition of hot gas in astronomical objects such as clusters of galaxies.” Jonathan McDowell, an x-ray astrophysicist at the Center for Astrophysics|Harvard & Smithsonian who works with the Chandra space telescope, tells that “XRISM’s images won’t be as sharp as Chandra and XMM-Newton, but it has excellent spectral (color) resolution – like a hyperspectral imager in the optical.”
X-rays don’t penetrate Earth’s atmosphere so space-based telescopes are the only way to study the universe in those wavelengths. They want to avoid a potential gap in X-ray observations between the aging Chandra (NASA) and XMM Newton (ESA) telescopes launched in the late 1990s and ESA’s ATHENA planned for the 2030s. X-ray astronomers have their fingers crossed XRISM will work. The JAXA-NASA-ESA X-ray Imaging and Spectroscopy Mission, XRISM. ESA provided a star tracker and other systems. XRISM is its replacement, but on a smaller scale with only two instead of four instruments: JAXA’s Xtend soft X-ray imager and NASA’s Resolve soft X-ray spectrometer that pairs an X-Ray Mirror Assembly with a microcalorimeter. In 2016, the JAXA-NASA Astro-H, or Hitomi, telescope broke apart in orbit due to an attitude control failure. The X-Ray Imaging and Spectroscopy Mission, XRISM (pronounced Chrism), is a cooperative program among the Japan Aerospace Exploration Agency (JAXA), NASA and ESA. The launch by Mitsubishi Heavy Industries (MHI) was delayed from August 27 EDT (August 28 in Japan) due to bad weather, but liftoff of the H-IIA rocket from Tanegashima tonight at 7:42 pm EDT (8:42 am September 7 Japan Standard Time) was perfect.
The telescope is a replacement for one that broke apart in orbit several years ago and SLIM is the third Japanese attempt to land on the Moon in the past 10 months. Weather finally cooperated and Japan’s space agency was able to launch its new x-ray telescope, XRISM, and lunar lander, SLIM.
