You cannot talk verbally across outer space because sound waves require a medium (matter, such as air or water) to travel through, and space is an almost perfect vacuum.
Space, being an almost perfect vacuum, does not allow sound to travel and be heard by the ears. Sound is vibrations of air particles, so any “sound” that is heard in space has to come from another source. As such, astronauts communicate with each other in space when they are spacewalking through the use of radio waves.
Astronauts can speak and hear inside the pressurized air of space capsules, space stations, and space suits. However they could not speak or transmit sounds across outer space. Sound waves are mechanical waves, so they can travel only through matter, such as air, and not through empty space.
In space, where there are only near-empty voids between galaxies, stars, and planets, there are no air molecules to let conventional sound propagate. Nonetheless, space is not entirely silent.
astronauts aboard the International Space Station (ISS) orbiting miles above Earth are now phoning home. ISS astronauts use Cisco Systems SoftPhone software running on flight-approved laptops through a voice-over-IP (VoIP) system.
It turns out that while most systems in the human body are heavily affected during spaceflight, the female menstrual cycle doesn't seem to change at all. “It can happen normally in space, and if women choose to do that, they can,” Jain said.
1. WiFi in space. NASA (National Aeronautics and Space Administration) installed the first access points for WiFi in space on the international space station in 2008. Later, more access points got installed on the station, with the network reaching into the expanse of space.
The bathroom is full of handholds and footholds so that astronauts don't drift off in the middle of their business. To pee, they can sit or stand and then hold the funnel and hose tightly against their skin so that nothing leaks out. To poop, astronauts lift the toilet lid and sit on the seat — just like here on Earth.
1 hour on Earth can equal 7 years in space (or vice versa) due to time dilation, a concept from Einstein's relativity where strong gravity or extreme speeds slow down time relative to an outside observer, famously depicted in the movie Interstellar on a planet near a black hole where an hour for the crew meant years passing on Earth. It's not about speed alone in orbit (ISS astronauts age slightly slower), but about proximity to immense mass, like a black hole, bending spacetime so drastically that time crawls for those nearby compared to time far away.
In 2019, NASA astronaut Anne McClain found herself at the center of a headline-grabbing controversy—accused of committing the world's “first crime in space.” 🛰️ While on a six-month mission aboard the International Space Station, McClain's estranged spouse, Summer Worden, filed a federal complaint claiming McClain had ...
NASA solved this problem by giving the females specifications for what they were allowed to wear. The underwear had to be cotton, since nylon might create sparks, and it had to be available at local department stores. The all-male crew equipment personnel told the women to pick out a bra and panties that they liked.
While the vacuum of space itself is silent, spacecraft are filled with noise from life-support systems, exercise equipment, and communications tools. Research reveals that prolonged exposure to these sounds doesn't just risk hearing damage. It also affects cardiovascular health, sleep quality, and mission success.
Astronauts can take cell phones to space, but they don't work like they do on the ground. We don't get cell service, but we can check our emails, conduct video calls, take photos, and listen to music.
They can pick up the phone or email whenever they have the time.” Today, astronauts on the Space Station have access to email and social media.
Flying Your Name to Jupiter on NASA's Icy Moon Explorer
More than 2.6 million people around the world joined NASA's Message in a Bottle campaign, a first-of-its-kind initiative that invited people to sign their names to a special message traveling 1.8 billion miles on the agency's Europa Clipper spacecraft.
Once every 176 years, the giant planets on the outer reaches of the solar system all gather on one side of the sun, and such a configuration was due to occur in the late 1970s.
Return to the Moon
Artemis II, scheduled for launch between February and April sees the return of the first people to the Moon since Apollo 17 in 1972. Three American and one Canadian astronaut will orbit the Moon on a 10 day journey that lays the foundation for lunar landings in the coming years.
After all, the twin on Earth can invoke time dilation: Moving clocks go slower, and so do the clocks of the moving twin. On these slower-moving clocks – and, by extension, in the whole spaceship – less time passes than on Earth, in other words: when the travelling twin returns, he is younger. No paradox so far.
NASA & MAGs or Maximum Absorbency Garments
It has since created Maximum Absorbency Garments, sometimes referred to as space diapers or MAGs. This piece of clothing is worn by astronauts during liftoff, landings, spacewalks, and extra-vehicular activities in which making it to a bathroom simply isn't possible.
Indirectly, yes. Television can be provided to the crew via two methods. Video files of individual programs can be uplinked to their computers for asynchronous viewing. A small library of film and television has been built up using that method.
Every 90 minutes on the International Space Station (ISS), astronauts experience a complete orbit around Earth, meaning they see a sunrise and a sunset, totaling 16 sunrises and 16 sunsets every 24 hours, which disrupts natural sleep cycles, leading to structured work/sleep schedules using Coordinated Universal Time (UTC) and special lighting to mimic day/night.
