[Web release] XRISM discovers evidence of rapid ionisation in a supernova remnant near the supermassive black hole in our galactic centre. Read more 👉 isas.jaxa.jp/en/topics/0039…

Dr. Kuninaka Hiroshi, then ISAS Director General, visited NASA Goddard and met with Director Dr Makenzie Lystrup to discuss recent US-Japan achievements in space science including XRISM. He toured the Roman Space Telescope assembly site and spoke on ISAS-GSFC collaboration.

ISAS Director General Fujimoto Masaki spoke online at the US National Academies #SpaceScienceWeek, highlighting Hayabusa2, MMX, SLIM, XRISM, & planetary defence. He discussed the significance of missions that serve as stepping stones in advancing international space science.

[Web release] A high-energy "accelerator" for cosmic rays close to a black hole binary has been imaged using the wide-field camera onboard the XRISM mission. isas.jaxa.jp/en/topics/0039…

[#ISASGate] Data from the #Arase mission has been used to uncovered a relationship between “pulsating auroras” on Earth which allow high-energy electrons to precipitate into the atmosphere, and tube-like pathways formed by electromagnetic waves from space. isas.jaxa.jp/home/research-…

[Press Release] X-Ray Imaging and Spectroscopy Mission (XRISM) Unveils Super High-Speed Bullet-Like Winds Shooting from a Supermassive Black Hole (Nature publication) #JAXA global.jaxa.jp/press/2025/05/…

For the first time, "bullet-like" winds blasting from a supermassive black hole at nearly light speed have been revealed. These powerful outflows challenge our understanding of how black holes and galaxies grow together. 🔗xrism.jaxa.jp/en/topics/scie…

[Web release] After 15 years of operation, the small-scale solar powered demonstration satellite, IKAROS, which became the first in the world to demonstrate a solar sail and solar powered sail, has ended operations. isas.jaxa.jp/en/topics/0040…

MMX is undergoing a thermal vacuum test, in which the spacecraft is placed in a vacuum chamber where the environment simulates outer space and the operation for each of the onboard instruments is checked. The return and exploration modules are ready to be tested in this photo!

[#CosmosBlog] Can we avoid the 7 minutes of terror? Testing out the next generation of rotating detonation rocket engines 🚀, and an alternative way to make the challenging descent to the Martian surface… with the inflatable RATS 🐀! Read on Cosmos 🔗: cosmos.isas.jaxa.jp/avoiding-the-7…

JAXA’s Sagamihara Campus welcomed the Australian Space Agency, including ASA Head Enrico Palermo and Astronaut Katherine Bennell-Pegg! Topics such as MMX were discussed with ISAS Director General Dr Fujimoto, and everyone joined a live event showcasing robotic–crewed mission integration.
