Today's the 50th anniversary of the day that - after 4 unsuccessful tries - Japan sent a satellite into orbit (the Ohsumi). With the Lambda-4S rocket still holding the smallest successful SLV record, the way it became the 4th country to sent something to orbit is pretty special.pic.twitter.com/XItO0uCLD3

It also happens that the Japanese still holds as the only ones that sent things into orbit with just spin/gravity-gradient stabilization (a feat replicated by a modified SS-520 sounding rocket in 2018) & the only ones in the 20th Century that went the fully civilian way!

Right at the anniversary mark, here are some photos of the actual launch, plus one long mission overview video from what was then the University of Tokyo Institute of Space and Aeronautical Science (now Institute of Space and Astronautical Science, JAXA)! http://jda.jaxa.jp/result.php?lang=e&id=6e900303d9437aa34cc9a14139e6f99b …pic.twitter.com/sYJCGoxdy9

Ah I'm not talking about the later liquid fuel rocket series, but
@ISAS_JAXA's series of sounding rockets program lead by Hideo Itokawa. In fact the solid fuel rockets (Lambda/Mu series) and liquid fuel rockets (N-I/II, H-I/II) were under different organizations until 2000!
