1951 in spaceflight

1951 saw a number of suborbital spaceflights, conducted to test missiles, or conduct scientific research. The Soviet Union conducted large numbers of R-1 and R-2 missile tests, whilst the United States launched several research flights using Aerobee and captured V-2 rockets.

gollark: Bold of you to assume I ever need that.

gollark: I have to admit Markdown's lists are pretty evil. So perhaps I should... develop my own Markdown-inspired but subtly incompatible version.

gollark: What would be the benefit of that?

gollark: TeX sounds kind of overkill. I mostly just need... headings, and lists.

gollark: I suppose I could just start writing Markdown or even HTML, which would have some benefits.
