10 Things for Space Made by Hand: Apollo Memory Woven Wire by Wire and 21-Layer Moon Suits

The only quilt block I ever finished took me three weekends, and my mom said the corners were “enthusiastic.” I have since learned that an astronaut stitched a neater one while floating on the space station. These 10 things for space were made by hand, from computer memory woven wire by wire to Moon suits sewn in 21 layers.

Apollo’s Software Was Woven by Hand, Wire by Wire, Into ‘Rope’ Memory

The Apollo Guidance Computer kept its programs in “core rope memory.” In rope memory, a wire threaded through a tiny doughnut-shaped magnetic core stood for a 1, and an empty core stood for a 0, so the pattern of wires was the program itself.

IEEE Spectrum says factory workers, usually women, “painstakingly encoded each bit of information by hand.” In 1969, that hand-woven memory held the navigation and guidance software that landed people on the Moon for the first time.

The Apollo Moon Suits Had 21 Layers and Were Sewn Largely by Hand

Neil Armstrong’s Apollo 11 suit was made of “no fewer than 21 layers of cloth and neoprene and glass coated threads,” TIME reported when the Smithsonian restored it. The layers had to protect astronauts from 260°F in direct sunshine and −280°F in shadow.

When the restorers went to work, there were flaws they decided not to touch, including “the occasional crooked stitch, a mark of the seamstresses who manufactured each lunar suit largely by hand.”

Katherine Johnson: The ‘Human Computer’ Who Checked the Electronic Computer’s Math

Katherine Johnson joined NASA’s predecessor in 1953 as one of a group of African American women hired as “computers,” people who did the calculations by hand. She calculated the trajectory of Alan Shepard’s 1961 flight, the first American in space.

Before the 1962 launch that sent an American astronaut into orbit for the first time, she verified the numbers the early electronic computers had produced, and she later checked the trajectory for Apollo 11. She worked at Langley Research Center until 1986.

‘Rise’: Artemis II’s Floating Moon Was Designed by an 8-Year-Old and Sewn at NASA

Crews often fly with a small plush toy as a zero-gravity indicator: when it starts to float, everyone is weightless. For Artemis II, which launched on April 1, 2026, the toy was Rise, designed by second grader Lucas Ye and picked from 2,605 entries from more than 50 countries.

Rise is a round white Moon with a tiny footprint on its back for the first Moon landing. The flight version was made at NASA’s Thermal Blanket Lab, where technician Pamela Cain used a mix of machine and hand sewing. She also added a pocket for a memory card with more than 5.6 million names.

The First Aircraft on Mars Carried a Swatch of the Wright Brothers’ 1903 Flyer

In 1903, the Wright brothers made the first powered flight on Earth in a plane they had built themselves. On April 19, 2021, NASA’s Ingenuity helicopter made the first powered, controlled flight on another world, and it carried a swatch from the original Wright Flyer.

Ingenuity was planned for up to five test flights over 30 days. It made 72 flights in almost three years and flew more than 14 times farther than planned.

Perseverance’s Parachute Had a Secret Message Built Into Its Pattern

When Perseverance landed in February 2021, its 70.5-foot parachute was the largest ever sent to Mars, and a camera on the spacecraft filmed it opening.

The orange and white panels were not random. In binary code, they spell out “DARE MIGHTY THINGS,” JPL’s motto, along with the GPS coordinates of a spot near JPL’s visitor center. A systems engineer on the mission designed the pattern.

The Voyager Golden Record: 115 Pictures, 90 Minutes of Music and Hello in 55 Languages

Each Voyager spacecraft carries a gold-plated record in a protective aluminum jacket, with a cartridge, a needle and symbol instructions on how to play it. A committee chaired by Carl Sagan chose what went on it: 115 images and natural sounds such as surf, wind, thunder, birds and whales.

They added 90 minutes of music from many cultures and eras, and spoken greetings in 55 languages, beginning with Akkadian, spoken in Sumer about 6,000 years ago. Both records left Earth in 1977 and are now in interstellar space.

The Pioneer 10 Plaque: A Drawn ‘Letter’ for Anyone Who Finds the Spacecraft

Pioneer 10 launched in March 1972 and became NASA’s first mission to the outer planets. It carries an aluminum plaque with drawings of a man and a woman, the solar system, and the Sun’s position relative to 14 pulsars, so that anyone who found it could work out where it came from.

The spacecraft was designed for a 21-month mission to fly past Jupiter. It kept going for more than 30 years and sent its last signal in January 2003, from 7.6 billion miles away.

LAGEOS: A 1976 Satellite Carries Maps of Earth for People 8.4 Million Years From Now

LAGEOS, a NASA satellite launched in 1976 so that scientists could bounce lasers off it from the ground, carries a plaque designed by Carl Sagan as a message to future civilizations. At the top, the numbers one to 10 are written in binary.

Below are three maps of Earth: 268 million years ago, when the continents were joined in a single land mass; the continents in 1976; and Earth 8.4 million years from now, when the satellite was originally expected to fall back down.

Karen Nyberg Quilted in Space in 2013, and More Than 2,200 Quilters Answered From Earth

In 2013, astronaut Karen Nyberg became the first person to quilt in space when she stitched a 9-by-9-inch red, white and blue star block aboard the International Space Station.

Her block became the centerpiece of a quilt festival challenge, and more than 2,200 quilters from around the world sent in their own space-themed blocks, which were sewn into 28 quilt panels. In 2024 she started a new Lunar Quilt challenge, with blocks from all 50 states, for an arts festival in Washington in spring 2025.

Karen Nyberg sewed one small block in a place where nothing stays where you put it, and more than 2,200 quilters answered her from the ground. My enthusiastic block is still the only one I’ve finished, but I’m starting to think it needs company.

Have you ever made something by hand that you were proud enough to send far away? Tell us in the comments.
