The Apollo 11 mission reached the moon 50 years ago. For those that were alive and watched the moon landing as it happened, it was an unforgettable moment.
But everyone born post-moon landing, it’s hard to grasp what a big moment it was, and kids are still curious about the moon and how we got there even with our current knowledge.
Fifty years after Apollo 11, we asked a few kids what they wanted to know about the moon and the moon landing and answered their lunar inquiries.
"Are their footprints still there?" — Emma, age 4
Yes, the footprints of Neil Armstrong and Edwin "Buzz" Aldrin are still on the moon today. Because the moon doesn't have any weather — no wind or rain — the footprints can't be blown or washed away.Here are some of the personal items the Apollo 11 astronauts took to the moon
“What is the moon made of? How big is the moon?” — Stella, age 9
It’s not cheese; the simplest answer is rock. Like the Earth, the moon has layers. Regolith, or lunar dust, covers a thick crust, which covers a mantle and a dense core.
The moon is about one-quarter of the size of the Earth. For some perspective: If Earth were the size of a nickel, the moon would be about the size of a coffee bean, according to NASA.
"Is it hot or cold on the moon?" — Olivia, age 5
It's both. During the moon's day, temperatures can reach up to 260 degrees Fahrenheit. At night, they can dip down to negative 280 degrees Fahrenheit. The moon doesn't have an atmosphere the way Earth does, which means it can't trap or block the sun's heat.How to experience the Apollo 11 mission as it happened, no time or space travel required
“How many craters are on the moon?” — Caroline, age 9
It’s hard to come to a definitive answer, but scientists estimate the moon has millions and millions of craters on the surface. There are over 5,000 lunar craters with a diameter of 12 miles or more, and the moon’s biggest crater — the South Pole-Aitken crater — is 1,600 miles wide. That’s about the distance from New York City to Denver, Colorado.
"There was supposed to be an Apollo 18, but it got cancelled. Why?" — Leah, age 9
There were originally going to be three more Apollo missions. Apollo 18, 19 and 20 were cancelled due to budget constraints, according to NASA. However, NASA is planning another trip to the moon by 2024.READ MORE: A brief history of NASA’s Apollo program
“Can you watch TV on the moon?” — Griffin, age 5
Hard to say, but astronauts can and do watch live TV on the International Space Station. The astronauts there also have a huge collection of movies and TV shows available to watch on the station, from the "Star Wars" original trilogy to "The Lego Movie."
