Throwback Thursday: Apollo 11 FAQ Edition
With the help of the NASA History Office, weâve identified some of the most frequently asked questions surrounding the first time humans walked on the surface of another world. Read on and click here to check out our previous Apollo FAQs.Â
How many moon rocks did the Apollo crews bring back? What did we learn?
The six crews that landed on the Moon brought back 842 pounds (382 kilograms) of rocks, sand and dust from the lunar surface. Each time, they were transferred to Johnson Space Centerâs Lunar Receiving Laboratory, a building that also housed the astronauts during their three weeks of quarantine. Today the building now houses other science divisions, but the lunar samples are preserved in the Lunar Sample Receiving Laboratory.
Built in 1979, the laboratory is the chief repository of the Apollo samples.
From these pieces of the Moon we learned that its chemical makeup is similar to that of Earthâs, with some differences. Studying the samples has yielded clues to the origins of the solar system. In March of 2019, we announced that three cases of pristine Moon samples will be unsealed for the first time in 50 years so that we can take advantage of the improved technology that exists today!Â

What did Apollo astronauts eat on their way to the Moon?
Astronaut food has come a long way since the days of Project Mercury, our first human spaceflight program that ran from 1958-1963. Back then, astronauts âenjoyedâ food in cube form or squeezed out of tubes. Early astronaut food menus were designed less for flavor and more for nutritional value, but that eventually shifted as technology evolved. Astronauts today can enjoy whole foods like apples, pizza and even tacos.Â
Apollo crews were the first to have hot water, making it easier to rehydrate their foods and improve its taste. They were also the first to use a âspoon bowl,â a plastic container that was somewhat like eating out of a Ziploc bag with a spoon. Hereâs an example of a dayâs menu for a voyage to the Moon:
Breakfast: bacon squares, strawberry cubes and an orange drink.
Lunch: beef and potatoes, applesauce and a brownie.
Dinner: salmon salad, chicken and rice, sugar cookie cubes and a pineapple grapefruit drink.
What did Michael Collins do while he orbited the Moon, alone in the Command Module?
As Neil Armstrong and Buzz Aldrin worked on the lunar surface, Command Module pilot Michael Collins orbited the Moon, alone, for the next 21.5 hours. On board he ran systems checks, made surface observations and communicated with Mission Control when there wasnât a communications blackout. Blackouts happened every time Collins went behind the Moon. In 2009, Collins wrote this in response to a flurry of media questions about the 40th anniversary of the mission:
Q. Circling the lonely Moon by yourself, the loneliest person in the universe, werenât you lonely?
A. No. Far from feeling lonely or abandoned, I feel very much a part of what is taking place on the lunar surface. I know that I would be a liar or a fool if I said that I have the best of the three Apollo 11 seats, but I can say with truth and equanimity that I am perfectly satisfied with the one I have. This venture has been structured for three men, and I consider my third to be as necessary as either of the other two.â
What will Artemis astronauts bring back when they land on the Moon?
Artemis missions to the Moon will mark humanityâs first permanent presence on another world. The first woman and the next man to explore the lunar surface will land where nobody has ever attempted to land before â on the Moonâs south pole where there are billions of tons of water ice that can be used for oxygen and fuel.
We donât know yet what astronauts will bring back from this unexplored territory, but we do know that they will return with hope and inspiration for the next generation of explorers: the Artemis generation.
