On July 20, 1969, Neil Armstrong's sons Mark and Rick were at the family home in Houston watching TV as their father stepped off the Eagle lunar module and into the pages of history.
Mark, who was 6 at the time, said their home was a hive of activity on the day of Apollo 11 Moon landing.
"We had two televisions in the house, so folks were huddled around both of them, some in the living room and some in one of the bedrooms, I think," he told Fox News. "Friends, family, neighbors, they were all coming in and out. And, of course, we had the squawk box, as well, which I believe was set up in the bedroom at the time, so we could hear what was happening, more than most. "

It was not just the Armstrongs and their friends who watched with rapt attention. An estimated 650 million people around the world watched the moon landing on TV, according to NASA.
Mark, who spoke at a Smithsonian Channel event in New York City celebrating the 50th anniversary of the Moon landing, explained that while it was an exciting day, he did not understand his importance until much later. "When you're that age, you do not really understand the historical context of things," the now 56-year-old said. "You can see it and feel it, you can feel the energy in the room and you can feel the amazement in the people around you, but you do not really understand why they are so amazed until you grow up a bit and you
Rick was 12 years old when his father stepped out of the Eagle lunar module and famously proclaimed "One small step for a man, one giant leap for mankind."
"When he stepped off, nobody in the room heard what the words were because they were all" what did he say? "" Rick told Fox News. "I heard it, and I said" something about a little step, "but at the time it was not clear what was going on, I always remember that."
The brothers recounted that in the weeks leading up to the Moon landing, their mother Janet was careful to insulate them from the tension surrounding the epic mission. "Our mother was obviously worried, but we did not see that, as her children. It's just like normal days for us in the weeks before, "Mark said.
His brother notes that his mother's strength and stoicism was typical of an astronaut's wife
" The risk, that part, I think was always [by] games, but I think that all the wives did that, try to keep life as normal as possible for the kids so they did not worry, "added Rick.
Their father also instilled confidence in them in the weeks leading up to launch. "What was discussed was that Dad said he's going on a flight, they have a lot of confidence in the mission, they have confidence in the spacecraft and they feel like they're ready to go," said Mark. "For us, that just seemed like, 'OK, Dad seems very confident, so we're not going to worry.'"
Both boys and their mother were at Cape Canaveral, which was then known as Cape Kennedy, on July 16, 1969, to watch their father, Buzz Aldrin and Michael Collins launch into space atop a huge Saturn V rocket. More than 1 million people are estimated to have watched the launch in the immediate vicinity of the Kennedy Space Center.

"We did not really see all the people," said Rick, who missed an all-star game for his Houston Little League to attend the launch. "I can not remember exactly where we were staying, but we watched it off of a boat. "
"A Saturn 5 launch is an amazing thing, that was what the focus was, what I remember from it, person, "he added.
"When you see the movie, you see it from the front, we were on the side," said Mark. "Because we were on the side, there was this huge bill of smoke that came out to the sides of the launchpad. And we were over there, all we saw was smoke for what seemed like an eternity. And eventually, you know, way up, this spacecraft just went right over the smoke and up to the sky, it was an amazing thing. "
About 50 years after their father, Aldrin and Collins made history, the brothers are keenly Apollo 11.
"The inspiration that people from all over the world got from that program to me, that is the legacy of Apollo," Rick told Fox News.
"I think it's more than the Apollo 11 astronauts. There are about 400,000 people who worked on that program and every one of them wanted to do the best job they could, "said Mark. "They did not want to be the weak link in the chain, so every one of them did their part and that's why the project was successful, and I think well ahead of its time, certainly from a technology standpoint."
"It was an amazing achievement and a great thing we did in this country," he added.
