ASTRONAUT BODY MEASUREMENT
In 2014, NASA astronauts used an ordinary tape measure during six-month ISS missions; the Body Measures data later entered requirements for NASA's xEMU spacesuitIn 2014, astronauts aboard the International Space Station conducted body measurements to study the impact of microgravity on human physiol...- In 2006, NASA launched 75 fruit flies on STS-121 for 13 days; Discovery returned with about 3,000, including a new generation that developed in spaceNASA's experiments with fruit flies in zero gravity unveiled significant weaknesses in their immune systems. Observations indicated these f...
- In 1947, the military sent fruit flies 67 miles into space to test radiation risks. 11 years later, NASA was founded in 1958, with animal flights underway in America now1947 mission was part of a larger American effort to understand whether living organisms could survive the journey into space. Beginning in...
- In 2010, NASA launched a 12-pound, loaf-of-bread-sized satellite with two Bacillus populations; radiation exposure reached about 15 times that of the ISS orbitNASA's O/OREOS mission embarked on an exciting journey to observe how bacteria withstand the rigors of space radiation. The compact satelli...
- In 1998, NASA sent oyster toadfish into space on Space Shuttle Columbia; over 16 days in orbit, researchers studied how their balance systems adapted to microgravityIn 1998, saltwater toadfish participated in the Columbia's Neurolab mission, offering insights into the effects of microgravity on the nerv...
- In 2003, researchers found freshwater snails had mated in space; their gravity-sensing statoconia were 50% larger by volume than matched ground controlsExperiments conducted aboard the Space Shuttle demonstrated that pond snails bred in microgravity possessed larger gravity-sensing structur...
- In 2014, NASA sent young and older mice into space; within 9 to 11 days, the younger ones began running group laps in zero gravityIn 2014, NASA launched a group of twenty mice to the International Space Station for groundbreaking research. Remarkably, the young mice ex...
- In 1989, the space shuttle Discovery carried 32 fertilized chicken eggs for 5 days; all 16 early embryos died, while 8 older embryos later hatched without anatomical malformationsIn 1989, the space shuttle Discovery transported thirty-two fertilized chicken eggs into microgravity. Although younger embryos did not end...

The fa...
- Why emergency blankets look like giant sheets of foil; a thin metallic coating reflects radiant heat toward the bodyEmergency blankets are designed to reflect radiant heat, effectively helping to maintain body warmth. This innovative technology has its ro...
- 52 astronauts left Earth for months in orbit, and within weeks their gut bacteria changed how they processed food, revealing why spaceflight can trigger constipation and potentially affect brain healthConstipation in space is more than an uncomfortable side effect. Astronauts often face it during long missions, but scientists have not ful...
- In 1969, Apollo 11 astronauts saw mysterious flashes with their eyes closed. Scientists later found the causeDuring the Apollo missions, astronauts noted peculiar flashes of light occurring inside their spacecraft. These experiences were later attr...
- On the ISS, astronauts see 16 sunrises every day as the station circles Earth, but their bodies refuse to follow the 90-minute cycle, forcing crews to stick to a familiar 24-hour routine despite living through multiple days and nightsAstronauts on the International Space Station experience sixteen sunrises daily. They follow a strict twenty-four-hour schedule, ignoring t...
- Key Largo used a sealed underwater habitat 22 feet below the surface to test prolonged human immersion; the result revealed a startling effect as a professor emerged after 100 days with his spine compressed and his height reduced by half an inchJoseph Dituri spent 100 days underwater in a 100-square-foot habitat near Key Largo, Florida. The extreme experiment changed more than his ...
- During Apollo, NASA fired grenades and crashed abandoned spacecraft into the Moon, measuring the tremors to investigate its hidden interiorDuring the Apollo missions, NASA cleverly detonated explosives on the Moon to investigate its seismic activity and inner structure. Seismom...
- In 2022, NASA slammed a spacecraft into an asteroid moonlet at 14,000 mph; humanity’s first planetary-defense test shortened its orbit by about 32 minutesNASA's DART mission achieved a groundbreaking success by colliding with the asteroid Dimorphos. This intentional impact resulted in a signi...
- In 2003, NASA sent tiny worms aboard Space Shuttle Columbia. After the disaster, scientists discovered that an aluminium container had helped them survive the deadly impactWhen Space Shuttle Columbiabroke apart on February 1, 2003, all seven astronauts lost their lives. Yet one NASA experiment survived. Tiny C...
