Write Her A Letter, Send Her A Flower, Love Only Gets Old If You Let It.

It’s sad when one has to paint a dark picture of another in order to paint a “perfect” picture of themselves.

Throwback Thursday: Apollo 11 FAQ Edition

With the help of the NASA History Office, we’ve 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. 

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 Center’s 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 Earth’s, 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!

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 “enjoyed” 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. 

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 “spoon bowl,” a plastic container that was somewhat like eating out of a Ziploc bag with a spoon. Here’s an example of a day’s 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 wasn’t 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, weren’t 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.”

What will Artemis astronauts bring back when they land on the Moon?

Artemis missions to the Moon will mark humanity’s 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 – on the Moon’s south pole where there are billions of tons of water ice that can be used for oxygen and fuel. We don’t 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.

What Would NASA Imagery Experts Pack for the Moon?

We are one step closer to landing the first woman and the next man on the Moon, and we want to know: What would you take with you to the Moon? 🌙

We are getting ready for our Green Run Hot Fire test, which will fire all four engines of the rocket that will be used for the Artemis I mission. This test will ensure the Space Launch System — the most powerful rocket ever built — is ready for the first and future missions beyond Earth’s orbit to the Moon.  

In celebration of this important milestone, we’ve been asking you — yes, you! — to tell us what you would pack for the Moon with the hashtag #NASAMoonKit!

To provide a little inspiration, here are some examples of what NASA imagery experts would put in their Moon kits:

“The first thing that went into my #NASAMoonKit was my camera. Some of the most iconic photographs ever taken were captured on the surface of the Moon by NASA astronauts. The camera has to go. The hat and sunscreen will be a must to protect me from the unfiltered sunlight. Warm socks? Of course, my feet are always cold. A little “Moon Music” and a photo of Holly, the best dog in the world, will pass the time during breaks.  Lastly, I need to eat. Water and gummy peach rings will go in a small corner of my pack.”

— Marv Smith, Lead Photographer, NASA Glenn Research Center 

“I may not always pack light, but I tried to only pack the essentials — with a couple of goodies. I get cold fairly easily hence the blanket, extra NASA shirt, hat and gloves. No trip is complete without my favorite snack of almonds, water, sunglasses, lip balm, phone, and my headphones to listen to some music. I figured I could bring my yoga mat, because who wouldn’t want to do yoga on the Moon? The most important part of this kit is my camera! I brought a couple of different lenses for a variety of options, along with a sports action camera, notebook and computer for editing. The Van Gogh doll was just for fun!”

— Jordan Salkin, Scientific Imaging, NASA Glenn Research Center

“The first thing I thought of for my #NASAMoonKit was the first book I ever read when I was learning to read. It is about going on a journey to the Moon. I really liked that book and read it many times, looking at the illustrations and wondering about if I would ever actually go to the Moon. Of the many belongings that I have lost through the years from moving, that book has stayed with me and so it would, of course, go to the Moon with me. A family photo was second to get packed since we always had photos taken and volumes of old family photos in the house. Photography has played an important role in my life so my camera gear is third to get packed. As a kid I spent a lot of time and money building rockets and flying them. I bet my rocket would go very high on the Moon. I also like a little candy wherever I go.”  

— Quentin Schwinn, Scientific Imaging, NASA Glenn Research Center

“I couldn’t go to the moon without my two mirrorless digital SLR cameras, lenses, my 120 6x4.5 film camera, several rolls of 120 film, my singing bowl (for meditation), my wireless printer, my son’s astronaut toy, several pictures of both my sons and wife, my oldest son’s first shoes (they are good luck), cell phone (for music and extra photos), tablet and pen (for editing and books), my laptop, and my water bottle (I take it everywhere).”

— Jef Janis, Photographer, NASA Glenn Research Center  

“I’m taking my NASA coffee mug because let’s be honest; nothing is getting done on the moon until I’ve had my morning coffee out of my favorite mug. I’m taking two cameras: the 360-degree camera and the vintage range finder camera my father bought during the Korean War when he was a Captain and Base Doctor in the Air Force. I’m also taking my awesome camera socks so I can be a fashion embarrassment to my family in space as well as on Earth. The lucky rabbit is named Dez — for years I have carried her all over the world in my pocket whenever I needed a little good luck on a photo shoot. She’s come along to photograph hurricanes, presidents, and sports championships. Being from New Orleans, I would love to be the first to carry out a Mardi Gras tradition on the moon, flinging doubloons and beads to my fellow astronauts (especially if we are up there during Carnival season). I also want to take a picture of this picture on the moon so my wife and son know they are with me no matter where I go. Lastly, it’s a well-known fact that space travelers should always bring a towel on their journey.”

— Michael DeMocker, photographer, videographer & UAS, Michoud Assembly Facility

“I couldn’t go to the Moon without my camera, a 45-rpm vinyl record (My husband’s band — I really want to know how a record sounds in space. Gravity is what makes the needle lay on the record so will the change in gravity make it sound different?), a book to read, a photograph of my daughter, my phone or rather my communication and photo editing device, a snack, and I definitely couldn’t go to the Moon without my moon boots!”

— Bridget Caswell, Photographer, NASA Glenn Research Center  

Laying the Groundwork for a New Generation of Commercial Supersonic Aircraft

Cabin crew, prepare for takeoff. Engines roar; speed increases. You sip a cold beverage as the aircraft accelerates quietly past Mach 1 or around 600 mph. There’s no indication you’re flying over land faster than the speed of sound except when you glance at your watch upon arrival and see you’ve reached your destination in half the time. You leisurely walk off the plane with ample time to explore, finish a final report or visit a familiar face. This reality is closer than you think.

We’re on a mission to help you get to where you want to go in half the time. Using our single-pilot X-59 Quiet SuperSonic Technology (QueSST) research aircraft, we will provide rule-makers the data needed to lift current bans on faster-than-sound air travel over land and help enable a new generation of commercial supersonic aircraft.

The X-59 QueSST is unique in shape. Each element of the aircraft’s design will help reduce a loud sonic boom, typically produced by conventional supersonic aircraft, to a gentle sonic thump, making it quieter for people on the ground. To prove the quiet technology works, we will fly the X-59 over select U.S. communities to gauge the public’s response to the sound.

We are working with Lockheed Martin in Palmdale, California, to manufacture the X-59 and are making significant progress, despite the pandemic.

We finished the majority of work on the wing and closed its interior, marking the halfway point on construction of the aircraft. 

The X-59 team at Lockheed Martin completed the final touches by fastening skins to the wing. A special sealant is applied so that fuel can be carried in the wings of the aircraft.

Moving at a steady pace, technicians continue to work on many parts of the aircraft simultaneously. The forebody section of the aircraft will carry the pilot and all the avionics needed to fly the aircraft.

Because of the X-59’s long nose, the pilot will rely on an eXternal Vision System (XVS), rather than a window, for forward-facing visibility. The XVS will display fused images from an advanced computing system and cameras mounted on the upper and lower part of the aircraft’s nose.

The aft part of the aircraft will hold an F414 GE engine and other critical systems. Unlike typical aircraft, the engine inlet will be located on the upper surface of the X-59 and is one of many features that will help reduce the noise heard on the ground.

Over the next several months, the team will merge all three sections together. After final assembly in 2021, the X-59 will undergo numerous tests to ensure structural integrity of the aircraft and that ¬its components work properly. First flight of the aircraft will be in 2022 and community testing will start in 2024, making way for a new market of quiet commercial supersonic aircraft.

The Rover Doctor is in: The Anatomy of a NASA Human Exploration Rover Challenge Rover

Exploration and inspiration collide head-on in our Human Exploration Rover Challenge held near Marshall Space Flight Center in Huntsville, Alabama, each April. The annual competition challenges student teams from around the world to design, build and drive a human-powered rover over a punishing half-mile course with tasks and obstacles similar to what our astronauts will likely have on missions to the Moon, Mars and beyond.

The anatomy of the rover is crucial to success. Take a look at a few of the vital systems your rover will need to survive the challenge!

The Chassis

A rover’s chassis is its skeleton and serves as the framework that all of the other rover systems attach to. The design of that skeleton incorporates many factors: How will your steering and braking work? Will your drivers sit beside each other, front-to-back or will they be offset? How high should they sit? How many wheels will your rover have? All of those decisions dictate the design of your rover’s chassis.

Wheels

Speaking of wheels, what will yours look like? The Rover Challenge course features slick surfaces, soft dunes, rocky craters and steep hills – meaning your custom-designed wheels must be capable of handling diverse landscapes, just as they would on the Moon and Mars. Carefully cut wood and cardboard, hammer-formed metal and even 3-D printed polymers have all traversed the course in past competitions.

Drivetrain

You’ve got your chassis design. Your wheels are good to go. Now you have to have a system to transfer the energy from your drivers to the wheels – the drivetrain. A good drivetrain will help ensure your rover crosses the finish line under the 8-minute time limit. Teams are encouraged to innovate and think outside the traditional bike chain-based systems that are often used and often fail. Exploration of the Moon and Mars will require new, robust designs to explore their surfaces. New ratchet systems and geared drivetrains explored the Rover Challenge course in 2019.

Colors and Gear

Every good rover needs a cool look. Whether you paint it your school colors, fly your country’s flag or decorate it to support those fighting cancer (Lima High School, above, was inspired by those fighting cancer), your rover and your uniform help tell your story to all those watching and cheering you on. Have fun with it!

Are you ready to conquer the Rover Challenge course? Join us in Huntsville this spring! Rover Challenge registration is open until January 16, 2020 for teams based in the United States.

If building rovers isn’t your space jam, we have other Artemis Challenges that allow you to be a part of the NASA team – check them out here.

Want to learn about our Artemis program that will land the first woman and next man on the Moon by 2024? Go here to read about how NASA, academia and industry and international partners will use innovative technologies to explore more of the lunar surface than ever before. Through collaborations with our commercial, international and academic partners, we will establish sustainable lunar exploration by 2028, using what we learn to take astronauts to Mars. 

The students competing in our Human Exploration Rover Challenge are paramount to that exploration and will play a vital role in helping NASA and all of humanity explore space like we’ve never done before!

Earth Facts that Live Rent-Free in Our Heads

Earth is a big weird planet. With so much going on, it’s easy to forget some of the many, many processes happening here. But at the same time, some stuff is so unexpected and just plain strange that it’s impossible to forget. We asked around and found out lots of people here at NASA have this problem.

Here are some facts about Earth that live rent free in our heads:

Earth has a solid inner core that is almost as hot as the surface of the Sun. Earth’s core gets as high as 9,800 degrees Fahrenheit, while the surface of the Sun is about 10,000 degrees Fahrenheit.

Dust from the Sahara fertilizes the Amazon rainforest. 27.7 million tons blow all the way across the Atlantic Ocean to the rainforest each year, where it brings phosphorus – a nutrient plants need to grow.

Ice in Antarctica looks solid and still, but it’s actually flowing – in some places it flows so fast that scientific instruments can move as much as a kilometer (more than half a mile!) a year.

Speaking of Antarctica: Ice shelves (the floating part of ice sheets) can be as big as Texas. Because they float, they rise and fall with the tide. So floating ice as big as Texas, attached to the Antarctic Ice Sheet, can rise and fall up to ~26 feet!

Melting ice on land makes its way to the ocean. As polar glaciers melt, the water sloshes to the equator, and which can actually slow the spin of Earth.

Even though it looks it, the ocean isn’t level. The surface has peaks and valleys and varies due to changes in height of the land below, winds, temperature, saltiness, atmospheric pressure, ocean circulation, and more.

Earth isn’t the only mind-blowing place out there. From here, we look out into the rest of the universe, full of weird planets and galaxies that surprise us.
