NASA astronauts must pass a grueling application process before being selected. Their annual salaries are determined using a government pay scale, and starting out, fall under two grades: GS-12 and GS-13. According to the 2018 government pay scale, an astronaut earns between $63,600 and $98,317 per year.
On the ISS, astronauts do not shower but rather use liquid soap, water, and rinseless shampoo. They squeeze liquid soap and water from pouches onto their skin. Then they use rinseless soap with a little water to clean their hair. An airflow system nearby quickly evaporates excess water.
According to NASA, civilian astronauts are awarded a pay grade of anywhere from GS-11 to GS-14, so the income range is relatively wide. Starting salaries begin at just over $66,000 a year. Seasoned astronauts, on the other hand, can earn upward of $144,566 a year.
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.
Neither the Soyuz rockets nor the Soyuz vehicles are reusable. With the solar panels open (they remain closed during launch) the Soyuz measures 10.6 m across. A Soyuz vehicle can carry up to three astronauts. A Soyuz is made up of three modules: the service, the orbital and the reentry modules.
approximately 8-1/2 minutes
It depends on the vehicle and what type of entry it performs. The Apollo capsules took 13 minutes and 26 seconds whereas the Space Shuttle Orbiter took 32 minutes.
A crew member sleeps in a sleeping bag located in a crew cabin. As a result, astronauts are weightless and can sleep in any orientation. However, they have to attach themselves so they don't float around and bump into something. Space station crews usually sleep in sleeping bags located in small crew cabins.
Depending on what particularly you are looking for (recurring copy of a space suit or the one made from scratch), the variance of the price may be as follows: Recurring copy of a spacesuit: from $2 to $10 million. Astronaut suit from scratch: from $300 to $500 million dollars.
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. It's the very diffuse gases and grains that drift through the cosmos whose temperature we can measure.
The temperature in outer space is 2.73 Kelvin (-270.42 Celsius, -454.75 Fahrenheit). This is actually the temperature of Cosmic Microwave Background Radiation, which is spread throughout the entire universe.
It is heavy when it takes off, but during the landing, having used up most of its fuel, it is low density and so slows down much higher in the atmosphere than the Space Shuttle. As a result, it will reach lower temperatures than the Space Shuttle on re-entry though higher than a supersonic jet at Mach 3.
Astronauts come back home inside the protective confines of a spacecraft, that's how. After re-entry is over and the spacecraft is back in the thicker atmosphere, parachutes open to lower the spacecraft to an ocean landing (most American vehicles) or ground landing (all Russian spacecraft).
The heat of re-entry is highly dependent on speed. The exhaust plume from that burn, as well, forces the atmospheric compression that creates reentry heat to occur well away from the rocket.
It's very like the space elevator, but you construct it downwards from a rather lower orbit than geostationary orbit. The bottom end can't be attached to anything so it just dangles in our atmosphere, traveling around, much faster than our Earth rotates. That's why it is called a skyhook.
The short answer is that most satellites don't come back to Earth at all. Satellites are always falling towards the Earth, but never reaching it - that's how they stay in orbit. They are meant to stay there, and usually there is no plan to bring them back to Earth.
about 17,500 miles per hour
The Soyuz does not land like an airplane because the Soyuz does not have wheels or wings. To land, the Soyuz drops through Earth's atmosphere. The atmosphere slows the Soyuz. The Soyuz uses parachutes to slow down even more.
The Apollo 1 crew, from left to right, Roger Chaffee, Ed White and Gus Grissom. During a preflight test Jan. 27, 1967, tragedy struck the Apollo 1 mission when a fire inside the space capsule caused the death of the three astronauts slated to travel to the moon. The event changed spacecraft design forever.
That's what's happens when astronauts dock with the International Space Station. Surprisingly though, the process can take a lot longer than you'd think. Although a rocket can transport astronauts into space in less than 10 minutes, it takes hours, and even days, to rendezvous with the International Space Station.
The astronauts realized that the problem was on the Gemini. By now the tumble rate had reached 296 degrees per second and Armstrong decided to shut down the OAMS and use the Reentry Control System (RCS) thrusters, located on the Gemini's nose, to stop the tumble.
The Apollo 11 Command Module Columbia carried astronauts Neil Armstrong, Edwin "Buzz" Aldrin, and Michael Collins on their historic voyage to the Moon and back on July 16-24, 1969.

The Lunar Gateway is an in-development mini-space station in lunar orbit intended to serve as a solar-powered communication hub, science laboratory, short-term habitation module, and holding area for rovers and other robots. It is expected to play a major role in NASA's Artemis program, after 2024.
In November 2015, Administrator Bolden of NASA reaffirmed the goal of sending humans to Mars. He laid out 2030 as the date of a crewed surface landing, and noted that planned 2020 Mars rover would support the human mission.
Mars 2020 Perseverance Rover
The largest and most capable rover ever sent to Mars.In April 1970, the crew of NASA's Apollo 13 mission swung around the far side of the moon at an altitude of 158 miles (254 km), putting them 248,655 miles (400,171 km) away from Earth. It's the farthest our species has ever been from our home planet.
NASA announced Monday it will order at least six reusable Orion crew capsules from Lockheed Martin for $4.6 billion to fly astronauts to the vicinity of the moon in the 2020s, and the agency said it plans to purchase hardware for up to 12 Orion vehicles by 2030.
Wernher von Braun proposal (1947 through 1950s) Wernher von Braun was the first person to make a detailed technical study of a Mars mission.
What's Next For NASA? In 2020, NASA will be taking long strides toward returning astronauts to the Moon, continuing the exploration of Mars and developing new technology to make supersonic aircraft fly more quietly.
NASA has selected the two spacecraft that will replace the Space Shuttle — taking astronauts to the International Space Station beginning in 2017. In a press conference Tuesday afternoon, NASA officials announced that both the SpaceX Dragon and Boeing CST-100 will move forward as part of the Commercial Crew Program.
