NASA, the United States’ space agency, is known for pioneering space exploration, technological innovation, and scientific discovery. While its accomplishments include the Apollo moon missions, Mars rovers, and the International Space Station, there are many lesser-known facts about the agency that highlight its wide-ranging contributions and unique history.
NASA Once Conducted an Experiment to See If Humans Could Survive on Pure Oxygen
During the early years of human spaceflight, NASA engaged in research to determine the best atmospheric conditions for astronauts in spacecraft. One approach was to test whether humans could live in a pure oxygen environment without experiencing negative effects. These studies were conducted in pressurized chambers to simulate the conditions astronauts would encounter in space.
The experiment revealed that while some astronauts could adapt to breathing 100% oxygen, it posed a fire hazard. Tragically, this issue became evident during the Apollo 1 mission in 1967 when a cabin fire caused by an electrical spark ignited the oxygen-rich environment, leading to the deaths of three astronauts. Following this disaster, NASA revised spacecraft cabin designs, opting for a mixed-gas atmosphere instead of pure oxygen during launch.
A Piece of the Wright Brothers’ Flyer Went to the Moon
When Neil Armstrong became the first person to walk on the Moon in 1969, he carried a small but historically significant relic with him. A piece of fabric from the Wright brothers’ Wright Flyer, the first powered aircraft to achieve controlled flight in 1903, was included in the Apollo 11 mission as a tribute to the pioneers of aviation.
The small piece of muslin fabric, along with a fragment of wood from the aircraft’s propeller, was stored in a protective container. This symbolic gesture represented the continuous progress of human flight, from the first airplane to the first Moon landing, in just 66 years.
NASA Accidentally Taped Over the Original Moon Landing Footage
One of the most significant moments in human history—the Apollo 11 Moon landing—was recorded and broadcast worldwide. However, years later, NASA inadvertently erased the original tapes due to routine data management procedures.
In the early 2000s, as the agency searched for the highest-quality recordings of the historic event, it was discovered that the tapes had been reused for other data storage. Thankfully, restored versions of the footage exist thanks to broadcasts recorded by television networks. Modern technology has allowed for digital enhancement of these recordings, preserving this momentous achievement for future generations.
A NASA Intern Bought Moon Dust at a Government Auction—And Won a Lawsuit to Keep It
In an unusual legal case involving lunar materials, a former NASA intern unknowingly purchased a sample of Moon dust from an auction in 2015. The item, a simple bag labeled “Lunar Sample Return,” was part of a government surplus sale, and the intern acquired it for less than ,000.
When NASA realized the bag contained actual Moon dust collected during the Apollo 11 mission, the agency attempted to reclaim it. However, a court ruled in favor of the buyer, stating that the purchase was legitimate under U.S. law. The intern later sold the bag at a private auction for .8 million.
NASA “Nasalnauts”
One of the more surprising aspects of NASA’s operations involves the meticulous process of “odor control” for spacecraft. NASA employs individuals, sometimes referred to as “nasalnauts,” to literally sniff materials intended for space travel. This isn’t a whimsical job; it’s a critical safety measure. In the confined environment of a spacecraft, even subtle odors can become overwhelming, and more importantly, the “off-gassing” of materials can release harmful chemicals. Therefore, NASA takes very seriously the process of making sure that the materials that are sent to space, do not have harmful or unpleasant smells.
This seemingly unusual task highlights the incredible attention to detail required for space exploration. Beyond the glamorous images of rocket launches and planetary discoveries, NASA’s work includes countless behind-the-scenes efforts to ensure astronaut safety and mission success. The fact that human noses play a role in cutting-edge space travel serves as a reminder that even in the age of advanced technology, basic human senses remain essential. Also, it shows that NASA has to consider many different human factors, when planning space missions.
NASA Developed a Special Recipe for Space-Grade Coffee
For years, astronauts had to drink coffee from vacuum-sealed pouches using straws, as the lack of gravity prevented traditional brewing methods. In response to the demand for a better space coffee experience, NASA collaborated with scientists and engineers to develop the “ISSpresso” machine.
The device, which was sent to the International Space Station in 2015, allowed astronauts to prepare espresso-style coffee safely in microgravity conditions. Unlike traditional coffee makers, this system used airtight capsules that prevented spills and ensured precise water flow. The invention not only improved quality of life aboard the space station but also contributed to research on liquid dynamics in space.
NASA Once Considered Sending a Mission to Explore Uranus with a Nuclear-Powered Probe
In the 1970s and 1980s, NASA studied the feasibility of sending a nuclear-powered spacecraft to Uranus and Neptune. The proposed mission, known as TOPS (Thermoelectric Outer Planets Spacecraft), was designed to operate using a radioisotope thermoelectric generator (RTG) and could have conducted extensive research on these distant worlds.
Budget constraints and shifting priorities within NASA led to the cancellation of the project. Instead, Voyager 2 conducted flybys of Uranus and Neptune, providing valuable data that continues to shape scientific understanding of the outer planets.
Astronauts Smuggled a Corned Beef Sandwich into Space
During the Gemini 3 mission in 1965, astronaut John Young secretly brought a corned beef sandwich aboard the spacecraft. Fellow astronaut Gus Grissom took a bite, only to realize that the food could pose a hazard, as loose crumbs began to float around the cabin.
The incident led to concerns about non-regulation food in space, as floating particles could interfere with equipment or be inhaled by the crew. As a result, NASA introduced stricter protocols for food preparation and consumption on subsequent missions.
NASA Tested Moon Landing Techniques in an Active Volcano
Before attempting lunar landings, NASA needed to train astronauts to recognize and navigate alien landscapes. One of the locations chosen for field training was Mauna Loa, an active volcano in Hawaii. The barren, rocky terrain of the volcano bore similarities to the Moon’s surface.
Astronauts, including members of the Apollo mission crews, practiced mobility techniques, geological sample collection, and the use of lunar equipment in this environment. The training prepared them for the challenges they would face on the actual Moon missions.
NASA Keeps Track of Over 27,000 Space Debris Objects
Earth’s orbit is increasingly cluttered with debris from defunct satellites, spent rocket stages, and other fragments from past space missions. To prevent collisions with active spacecraft, NASA continuously monitors more than 27,000 pieces of space debris.
The agency’s Orbital Debris Program Office uses ground-based radar, telescopes, and space tracking systems to catalog and predict the paths of these objects. This effort is essential for reducing the risk of collisions, which could generate even more hazardous debris and threaten the safety of future missions.
