【Countdown: 4 Days to XRISM Launch】
Earlier in August, XRISM was joined with the PAF and rocket fairing, marking a crucial step after propellant charging.

Take a look at these snapshots capturing the fairing assembly process. 🛰️🚀 #JAXA

XRISM Mission Ready To Explore Universe’s Hottest Locales

Japan’s XRISM (X-ray Imaging and Spectroscopy Mission, pronounced “crism”) observatory, expected to launch Aug. 25 (Aug. 26 Japan local time), will provide an unprecedented view into some of the hottest places in the universe. And it will do so using an instrument that’s actually colder than the frostiest cosmic location now known.

“XRISM’s Resolve instrument will let us peer into the make-up of cosmic X-ray sources to a degree that hasn’t been possible before,” said Richard Kelley, NASA’s XRISM principal investigator at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. “We anticipate many new insights about the hottest objects in the universe, which include exploding stars, black holes and galaxies powered by them, and clusters of galaxies.”

On a background ranging from dark blue (lower left) to bright purple, upper right), an S-shaped scales shows temperatures on the Kelvin scale in factors of 10. To its left and right, illustrations show cosmic examples in Fahrenheit and Celsius.
Explore the temperatures of the cosmos, from absolute zero to the hottest temperatures yet achieved, with this infographic. Targets for the XRISM mission include supernova remnants, binary systems with stellar-mass black holes, galaxies powered by supermassive black holes, and vast clusters of galaxies.

A new NASA infographic illustrates the enormous range of cosmic temperatures. At the bottom of the scale is absolute zero Kelvin, or 459.67 degrees below zero Fahrenheit (minus 273.15 Celsius).

The detector for XRISM’s Resolve instrument is just a few hundredths of a degree warmer than this. It’s 20 times chillier than the Boomerang Nebula – the coldest-known natural environment – and about 50 times colder than the temperature of deep space, which is warmed only by the oldest light in the universe, the cosmic microwave background.

The instrument, a collaboration between NASA and JAXA (Japan Aerospace Exploration Agency), must be kept so cold because it works by measuring the tiny temperature increase created when X-rays strike its detector. This information builds up a picture of how bright the source is in various X-ray energies – the equivalent of colors of visible light – and lets astronomers identify chemical elements by their unique X-ray fingerprints, called spectra.

“With current instruments, we’re only capable of seeing these fingerprints in a comparatively blurry way,” said Brian Williams, NASA’s XRISM project scientist at Goddard. “Resolve will effectively give X-ray astrophysics a spectrometer with a magnifying glass.”

XRISM’s other instrument, called Xtend, developed by JAXA and Japanese universities, is an X-ray imager that will perform simultaneous observations with Resolve, providing complementary information. Both instruments rely on two identical X-ray Mirror Assemblies developed at Goddard.

XRISM is a collaborative mission between JAXA and NASA, with participation by ESA (European Space Agency). NASA’s contribution includes science participation from the Canadian Space Agency.

NextSpaceFlight is showing a one day delay to 27 August at 00:30 UTC.

https://nextspaceflight.com/launches/details/5135

Update from MHI. Delay is due to predicted bad weather.

https://www.mhi.com/news/23082402.html

"Mitsubishi Heavy Industries, Ltd. (MHI) has postponed the launch of the H-IIA Launch Vehicle No. 47 (H-IIA F47) which carries aboard "XRISM(Note1)" and "SLIM(Note2)" produced by JAXA due to a bad weather forecast. Updated launch schedule is as follows:

Launch Date    Sunday, August 27, 2023
Launch Time    9:30:15 am (Japan Standard Time, JST) (Note3)
Reserved Launch Period:    August 28 through September 15, 2023"

XRISM in a nutshell

XRISM will study the Universe in X-ray light with an unprecedented combination of light collecting power and energy resolution – the capability to distinguish X-rays of different energies. The mission will provide a picture of the dynamics in galaxy clusters, the chemical make-up of the Universe and the flow of matter around accreting supermassive black holes (Active Galactic Nuclei or AGN), among many other topics.

🚀 H-IIA Rocket No. 47 Vehicle movement 🚀

Delivering the movement of the H-IIA rocket No. 47 💫

It took about 30 minutes to move the aircraft equipped with XRISM and SLIM from VAB (Large Rocket Assembly Building) to LP1 (Launch Point 1)!

The collaboration with the moon is beautiful 🌕✨
