Today is the 50th anniversary of the successful launch of the Japanese rocket Lambda-4S which was the smallest orbital rocket ever (until 2018) and the work of one of the smallest and scrappiest space programs of the 60's space race. Also one of the only purely civilian/academic ones.

It's one of my favorite rockets of all time!
