- In 2005, NASA flew five thick-toed geckos aboard Foton-M2 for 16 days without food or water; all were recovered with no apparent negative health effectsFive geckos orbited Earth for sixteen days without food or water. Researchers studied how weightlessness affects these cold-blooded animals...
- In 1987, Bion 8 carried monkeys Yerosha and Dryoma for 13 days; Yerosha escaped part of his restraints before the capsule landed 1,850 miles off targetThe Soviet Bion program studied weightlessness effects using rhesus macaques. Bion 8 launched in 1987 with two monkeys, Yerosha and Dryoma....
- In 1974, Skylab 4 astronauts returned after 84 days in orbit; flipped circuit breakers cut pitch-and-yaw control before Carr used backup mode for reentryThe Skylab 4 mission set a new record with astronauts spending 84 days in space, where they conducted crucial scientific experiments while ...
- In 1972, NASA sealed 3 astronauts inside a 20-foot chamber for 56 days to rehearse Skylab; the ground experiment exposed hardware and medical problems before launchIn 1972, three astronauts conducted a remarkable ground simulation, residing in a sealed chamber for a staggering 56 days. This experiment ...
- A 2026 Australian study finds controlled breathing may reduce addiction cravings after scientists analyzed 20 studies involving 1,249 people; researchers found breathing-based interventions significantly lowered cravings for nicotine, alcohol and other drugsA new study found controlled breathing significantly lowers cravings for various substances.

- In 1997, NASA sent 64 desert beetles to Russia’s Mir space station with tiny wheels tracking their every movement; their movements helped scientists understand how light regulates biological clocks in microgravityNASA sent black desert beetles into space aboard the Space Shuttle Atlantis in 1997. These insects lived on the Russian Mir space station f...
- In 1958, the US launched Gordo the squirrel monkey 300 miles above Earth; he endured 8.3 minutes of weightlessness and 40 g during re-entry, but died after his capsule sank at seaIn the historic space flight of 1958, Gordo, a courageous squirrel monkey, faced intense conditions that ultimately validated human surviva...
- In 1961, NASA sent Ham the chimpanzee 157 miles above Earth to test whether a primate could work in space; he completed a 16-minute flight and returned safelyChimpanzee Ham made history in 1961 when he soared into space aboard a Mercury-Redstone rocket. His mission aimed to assess the capabilitie...
- 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...
