Tenma

Tenma, known as ASTRO-B before launch (COSPAR 1983-011A, SATCAT 13829), was a Japanese X-ray astronomy satellite, developed by the Institute of Space and Astronautical Science. It was launched on February 20, 1983 using a M-3S rocket on the M-3S-3 mission.

Tenma (Japanese for "Pegasus").

Battery failure in July 1984 caused the operation to become limited, and continuing problems lead to the termination of X-ray observation in 1985. It reentered the atmosphere on January 19, 1989 (other sources, for example the NORAD catalog of satellites, say decay date was 17 December 1988[1]).

Highlights
  • Discovery of the iron helium-like emission from the galactic ridge
  • Iron line discovery and/or study in many LMXRB, HMXRB and AGN
  • Discovery of an absorption line at 4 keV in the X1636-536 Burst spectra
gollark: Oh, fun idea, PotatOS could have a logging mechanism and decent IPC thing.
gollark: A few things to look for might be... bytecode, I guess, keywords like "payload", "uninstall", some process IDs as 6_4 suggested, hmm, what else.
gollark: That might be good.
gollark: I'm wondering how to detect exploit-looking code now. This is probably a Hard Problem.
gollark: Exactly, mysterious characters I can't type.
