The greatest adventure in mankind, the Apollo 11 mission, is celebrating its 50th anniversary.
“We had two televisions in the home, one color and one black and white. We also had a squawk box, which was a way of listening to what was happening in mission control,” Mark told Inside Edition.
"It was a great memory," Rick added.
The Armstrong brothers revealed what their dad said to them shortly before he and fellow Apollo 11 crewmen Buzz Aldrin and Michael Collins climbed into the spacecraft for their launch.
“He was confident. He said there was risk but he felt really good about the spacecraft and everybody felt ready for the mission,” Mark said.
The Armstrong brothers are part of the Smithsonian Channel's upcoming special "The Day We Walked on the Moon."
Meanwhile, at the National Air and Space Museum in Washington Tuesday, Vice President Mike Pence unveiled Armstrong’s actual space suit, back on display after a 10-year restoration.
