> With Apollo everything was unknown, huge rockets, space suits, life support, space rendezvous, cameras, pens, even Tang.
Tang wasn't invented for the space program, it was merely a commercial food product they happened to find a use for. The Space Pen was inspired by the needs of the space program and was used in it, but wasn't a prerequisite for it.
I believe the color video camera for was specially made by RCA, but the workhorse still camera was an off-the-shelf Hasselblad.
I had thought that the Space Pen was an existing commercial product. Apparently I was only half right. Thanks for the link.
