Humans are the same here and in space, and we need the same things to survive: food, air, water, and protection from the weather. The critical technologies needed in space are those that provide these necessities—like the capsule that holds in the air and protects astronauts against the radiation and vacuum of ...

The planets Jupiter, Saturn, Uranus, and Neptune are the closest in character. They are very large, cold, gaseous planets. The other five planets are very different in character from the gas giants and are also very different from each other. ---- Answer provided by Ed Frederick, Ph.D. Image:K2S logosmall.jpg Question and Answer extracted from the ...

... , are outside our definitions of space. Look at the middle of a piece of paper. How far is it from one side of the paper to the other? The sides of the paper are the thickness of the paper apart, but you would have to travel about eight inches to get to the edge of the paper and around to the other ...

... better dog spacesuits. However, contrary to mid-1900s spaceflight, human spaceflight is now preferred and more successful, and so dog spacesuits are not readily available. For more modern scientific experiments on the Space Shuttle, smaller animals and rodents such as rats are used. They are enclosed in a protective module that houses the animals and the ...

... protected from the heat and the cold, the astronauts must also be protected from the radiation in space. A spacesuit is made by sewing and cementing eleven different layers of materials together. Metal parts are then attached to join the ...

Spacesuits are designed by engineers, not for fashion but for a particular usage. The ACES, worn by astronauts during ascent, re-entry, and landings, is designed specifically to provide ... . The EMU is designed to protect the astronaut outside the spacecraft. Protection from the extreme heat and cold conditions of the hostile space environment will continue to be a critical requirement for present and future spacesuit ...

... have to be brought to space in tanks. The oxygen tanks would be used to inflate the hotel and establish the environment. The oxygen in the hotel would have to be continually filtered and moisture ... (1:4) for breathing. This is what we call a shirt-sleeve environment, so there will be no need for air helmets or spacesuits when you are inside, unless there is an emergency. Any space modules we build must be air-tight, so breathable air will not leak out to space. With inflatable modules, there are ...

... in space, the color or reflective properties of an object in space are important. A black object absorbs more light and gets warmer than a white object. The astronauts have white spacesuits which reflect sunlight to keep them from getting too hot in direct sunlight, and they have heaters to keep them warm in shadow. Inside their suits the temperature ...

... Russia will all have at least one on-orbit laboratory as part of the ISS. Each laboratory differs in size. The US laboratory (named Destiny), for example, is 28 feet long and 14 feet in diameter and the Japanese laboratory (named Kibo, which means "hope" in Japanese), is ... go to the bathroom. There are also windows so the crew can look out at space or the Earth. There are places to store food and water, and there is an airlock that the astronauts use ...

Depending on the size and complexity of the rocket ship, there may be thousands of parts. They are usually grouped by systems, such as structures; propulsion; electrical power generation and distribution; avionics; life ... broken down into subsystems. For example, avionics may be divided into displays and controls (in the cockpit); data processing (computers, data busses, storage devices); communications (radios, lasers); instrumentation (guidance, navigation, control ...
