Astronauts must have oxygen, food, water, and rest. These needs are usually simple to meet on Earth; to meet these needs in space is very complicated. The gases in space cannot support human life. In fact, most of space contains no gases at all—it is what scientists call a vacuum.
A space station needs air, water, food and power. A toilet also comes in handy.
That includes food, clothing, mid-deck seats, flight tools, cameras, parachutes, safety equipment, sleep restraints and, most importantly, the astronaut spacesuits — known as “extravehicular mobility units.” Each spacesuit weighs over 200 pounds and is received in four pieces.
It has no phone number in the traditional sense, and astronauts have to leave their smartphones at home. For private calls, the space station has an internet-connected phone system that works through a computer, which astronauts can use to call any number on Earth. Phones on the ground cannot call them back, however.
Current satellite internet works using large spacecraft that orbit 22,236 miles (35,786 km) above a particular spot on the Earth. But at that distance, there are generally significant time delays in sending and receiving data. … As of late May 2021, SpaceX had launched more than 1,730 Starlink satellites overall.
The Space Station’s water recycling system produces pure drinking water from waste water, sweat and even urine. … Using a process called electrolysis, which involves running electricity through water, astronauts and cosmonauts are able to split the oxygen from the hydrogen. By the way, do NOT try this at home.
In space, there is very little breathable oxygen. A ground—based experiment by an experimental astrophysicist at Syracuse University found that oxygen atoms cling tightly to stardust. … Their spacesuits are outfitted with a backpack called the Primary Life Support Subsystem that provides breathable oxygen.
On the International Space Station, or ISS, astronauts quickly snap photos outside the window. … To ensure they capture a great shot, astronauts always keep eight cameras at the ready in the cupola of the space station, so someone can grab a camera and snap a picture when needed.
The minimum qualifications necessary to become an astronaut are listed on NASA’s website. In order to become a NASA astronaut, someone needs to be a U.S. citizen and must earn a master’s degree in biological science, physical science, computer science, engineering or math.
There is wifi on the space station. You’ll probably see pictures of the space station, you’ll see astronauts with iPads or laptops not connected by cables. … So using those you can get HD video, you can get pictures, you can get mostly all the data that NASA uses.
Yes, they can and do watch TV shows on the ISS. From an interview with Scott Kelly aboard the ISS: Apart from posting pictures to Twitter and Instagram, Kelly also said he spends some of his limited downtime watching television.
Answer: That number times 1 hour is 0.0026 seconds. So a person at that deep space location would have a clock that would run for one hour, while that person calculated that our clock ran for 59 minutes, 59.9974 seconds.
Remains are generally not scattered in space so as not to contribute to space debris. Remains are sealed until the spacecraft burns up upon re-entry into the Earth’s atmosphere or they reach their extraterrestrial destinations.
Yes, for a very short time. The principal functions of a spacesuit are to create a pressurized, oxygenated atmosphere for astronauts, and to protect them from ultraviolet rays and extreme temperatures. … At most, an astronaut without a suit would last about 15 seconds before losing conciousness from lack of oxygen.
“There are many risks to conception in low or microgravity, such as ectopic pregnancy,” Woodmansee said. “And, without the protection of the Earth’s atmosphere, the higher radiation levels raise the probability of birth defects.”
The pay grades for civilian astronauts are GS-11 through GS-14, based on academic achievements and experience. Currently, a GS-11 astronaut starts at $64,724 per year; a GS-14 astronaut can earn up to $141,715 in annual salary [source: NASA].
A combined oral contraceptive, or the pill, used continuously (without taking a week off to induce menstrual flow) is currently the best and safest choice for astronauts who prefer not to menstruate during missions, says Varsha Jain, a gynecologist and visiting professor at King’s College London.
Surprisingly, that isn’t the biggest problem associated with farting in space. Though you’re definitely more likely to worsen a small fire when you fart, it won’t always injure or kill you. The worst part about farting in space is the lack of airflow. Let’s take a step back and remember how farting on Earth works.
The biggest, immediate problem with “openning the door” of a spacecraft is not that you would die immediately from exposure to the vacuum of space: you don’t – you have of the order of minutes to do something about it. The problem is the violent outrush of air.
An astronaut can choose from many types of foods such as fruits, nuts, peanut butter, chicken, beef, seafood, candy, brownies, etc. Available drinks include coffee, tea, orange juice, fruit punches and lemonade. As on Earth, space food comes in disposable packages.
If atoms come to a complete stop, they are at absolute zero. Space is just above that, at an average temperature of 2.7 Kelvin (about minus 455 degrees Fahrenheit). But space is mostly full of, well, empty space. It can’t move at all.
