On July 20, 1969, Neil Armstrong and 'Buzz' Aldrin became the first humans to set foot upon a world other than Planet Earth when they walked upon the moon.
Since then, once further Apollo moon missions had been completed, humankind has remained steadfastly earthbound or in orbit around it.
Over the next few days KJM Today will be looking at The US Space programme, that of Russia and others, and will speculate as to what might come next, asking the question; will there be a next time and if so, when?
In Part One we look back at Apollo 11 and the historic event that saw the success of that mission. All images courtesy of NASA.
