Astronauts

Scientists and Explorers are alike because they both have to draw conclusions and search for the unexpected. So a way their different is that a scientist stays in a lab and tries to solve diseases with cures, but Explorers have to go and look for those things and another alike trait would be that scientists and explorers always have to have preparedness and risk taking. Scientists have a variety of ways to do things as do explorers. Ways that Scientists and Explorers are different would be that explorers have no boss; they can go out into the world and get lost with Mother Nature.

Because without fun of some sort, an astronaut's life would be pure stress. Unless you relieve that stress, then you start impairing your performance. The same can happen with earthbound people who have high-stress jobs or are in high-stress situations.

Yes there are some toilets in space. Astronauts started with adult diapers. But for longer missions, this was not ideal. Plastic bags were taped to astronaut backsides for collection. Liquids were also collected in bags but leaks proved annoying. Eventually a space toliet was created with a fan to pull odors away and help pull wastes away in low gravity. Scientists are still working on a better space toliet.

No, astronauts do not take off their helmets to eat.

Astronauts do not normally wear their helmets except when exposed to the vacuum of space. They are not normally exposed to space when in a spacecraft (Apollo, Skylab, Shuttle, Space Station, etc.). They eat while in the spacecraft, so there is no need to remove their helmets.

Apollo 1- a launch pad test resulted in a fire in the space capsule exacerbated by the fact that, at that time, NASA had a high oxygen atmosphere in space capsules, which greatly intensified the fire. The 3 astronauts in the capsule were killed, Grissom, White and Chaffee.
They were the only Astronauts lost in the Apollo program.

The Space Station and Shuttle astronauts keep Houston time, and sleep when it's night time in Texas. In the old Soviet-era Mir space station, the cosmonauts kept Moscow time. However, I believe that like ships, the ISS and Shuttle astronauts keep "watches", so that someone is awake at all times.

There are 2 major ways - under water (you are buoyant and feel like you weigh less) and in small hops in airplanes at the edge of the atmosphere (think of bungee jumping for 1 to 5 miles but you are inside the plane - you would be free falling inside the plane.) Nothing is exactly as it will be but, getting used to these really helps.

Since Saturn is a gas giant, there is no solid surface, making it impossible for astronauts to land a spacecraft. It may be possible to fly into its atmosphere, however this probably will not happen in the near future.

Through safety equipment and procedures and their intensive training.

A cosmonaut is another term for an astronaut. Generally, the term "cosmonaut" is used only for astronauts associated with the Soviet or Russian space program.

There is no air on the moon. Its atmosphere is so thin as to be nearly undetectable. Without bringing oxygen from the Earth the astronauts would have perished.

False. The centrifuge is a machine with a compartment at the end of a rotating circular arm, used to simulate the physical stresses of space travel during astronaut training.

None and never. 12 men have walked on the moon and all those men were males.

Most astronauts have to go to the hospital anyways for a check up before they leave for space. Some astronauts get hurt or injured n space and may need to get tothe hospital when they return. When astronauts get back they have an examination too. Astronauts are highly trained, but they are still human and can get sick or injured like anyone else.

The Jupiter C launch vehicle - a modified Redstone ballistic missile carried the Explorer I spacecraft, officially known as Satellite 1958 Alpha, the first United States earth satellite into space on February 1, 1958.

Yes, but both are special devices designed for use in microgravity. They use a blender like mechanism to handle solid waste in the toilet and both use wet vacuum cleaner type mechanisms to contain and remove the liquids.

The name of the spacecraft to that carried man to the moon was the Apollo11 and the lunar module was called The Eagle.

John H. Glenn, jr. He flew on shuttle Discovery (STS-95 mission) at the age of 77 years beginning October 29th and ending November 6th, 1998

He spoke the first words on the moon: "Okay. Engine Stop".

He is best remembered for his description of the lunar landscape as 'magnificent desolation.'

An object is said to be in free fall when the only force acting on it is its weight. All objects in a vacuum fall at the same rate regardless of their masses. All bodies in orbit, including the International Space Station (ISS), are in free fall, but as long as they are going fast enough their momentum keeps them in orbit instead of falling down. Since the net force acting on the astronauts and cosmonauts in the ISS are exactly the same as those acting on the ISS itself, with respect to the ISS they experience a net force of zero, which means that they are experiencing weightlessness.

the femenine of astronaut is astronaut. have you ever heard of an 'astroladynaut' or whatever else?

Astronauts bring water into space by bottles and canteens. They strap these containers to the walls with Velcro so it won't float away. To see how much water they carry, see the related question below.
