I just happened across this when searching the web for information on flash powder.
We always think of the first space research as being a 1940s-1960s phenomenon. In 1916, Robert Goddard did experiments to determine how much flash powder it would take to be seen on the moon from Earth via a 12-inch (30 cm) telescope. He empirically derived that it would take 2.67 lbs (approx. 1.2 kg).
I'm amazed to find that before the Great Depression, there was serious research about sending a rocket to the moon and having it signal back to Earth. Here is the box he used for the experiments (National Air and Space Museum):
