In early 1990s, NASA sent jellyfish to space to test how spaceflight would affect their development. The jellies did not develop the proper gravity-sensing capabilities and had trouble figuring how to swim around in normal gravity, with abnormal pulsing and movement when returned to Earth.
On May 2nd 2019, an extremely high resolution image was made from 16 years of observations from the Hubble telescope. This image is the deepest view of the universe, containing roughly 265,000 galaxies and stretches through 13.3 billion years to just 500 million years after the big bang.
In 1977 Jupiter, Saturn, Uranus, and Neptune were entering a rare alignment that occurs every 175 years. This happened to be when humans were first attempting space exploration so we were coincidentally able to send Voyager 2 on a flyby of all four planets on its way out of the solar system.
On March 18, 1965, Soviet cosmonaut Alexei Leonov became the first man to walk in space. The 30-year-old Russian floated outside the Voskhod 2 spacecraft for 12 minutes while connected to a 16ft tether.
Astronauts Mark Lee and Jan Davis married in secret 9 months before their joint flight to the ISS and didn’t tell NASA until it was too late to train replacements. They are the only married couple to have ever flown in space together.
November 2, 2000 was the last time all humans were on the planet together. Since then at least one person has remained on the international space station.
The asteroid belt is no where near as crowed as portrayed in movies and on TV. There are millions of kilometers between each object and astronauts would probably not even realize they were flying through the belt.
Carl Sagan convinced NASA to turn the Voyager Spacecraft towards earth and take the iconic “Pale Blue Dot” photo nearly 4 billions miles away from earth.
The Voyager probes took more than 40 years traveling at 40,000 mph to leave our solar system, but it will be another 40,000 years before they get anywhere near another star.
In 2015, Canadian astronaut Chris Hadfield released the first ever album recorded entirely in space, named Space Sessions: Songs from a Tin Can.
The first crime perpetrated in space was by astronaut Anne McClain, accused of illegally accessing her wife’s bank account during her stay on the International Space Station.
Carl Sagan’s team wanted to include the Beatles song “Here Comes the Sun” on the Voyager Golden Records (discs containing greetings in 60 languages, music and sounds from Earth aboard both Voyager spacecraft launched in 1977), but the record company EMI, which held the copyrights, declined.
