The lander had a mass of 99 kilograms. It used a landing bag to survive the impact speed of 22 kilometres per hour. It was a hermetically sealed container with radio equipment, a program timing device, heat control systems, scientific apparatus, power sources, and a television system. Wikipedia
As a boy I was fascinated by the Apollo Moon landings, starting especially with Apollo 8 when men travelled to the moon for the first time (without landing) and culminating in Apollo 11 (the first landing) and subsequent missions – so much so that I kept a scrapbook and folder of memorabilia at the time.
NASA has now uploaded 19,000 hours worth of audio from the historic Apollo 11 mission which saw the first humans walk on the Moon. You can search the archive or click ‘Surprise Me’ on the website: app.exploreapollo.org
