It is important for an astronaut to have acceptable visual and auditory reactions because anything can happen when in space. They need to be able to quickly assess the situation and react appropriately.

How does the space shuttle move in space?
Most of the movement, the orbiting of the shuttle around Earth, comes from the launch which gets the shuttle up to over 17,000 miles per hour. While in orbit, astronauts use the the shuttle's reaction control system to make adjustments to the shuttles orbit. The main engines are used again at the end of the mission to slow the shuttle down allowing the Earth's gravity to the rest of the work to bring the shuttle and astronauts back to the ground.
Why do astronauts feel gravity in space?
There is always gravity between two objects. If the astronaut is in a stable orbit around an object, he/she will not sense any gravity. If he/she is standing on the object, such as the Moon, there will be a sense of gravity. In the case of the moon, its gravity is about one sixth that of Earth. Also, if the spacecraft is accelerating, the the reaction force of the engine will cause the sense of gravity as well.There is also gravity between the astronaut and the spaceship, but that is so small that it will generally not be noticed.
How do astronauts get a supply of fresh air?
The astronauts on a space mission usually have just the air they take with them (there have been some experiments in storing liquid gases to mix). The carbon dioxide is removed from the air, either by chemicals such as lithium hydroxide, or by using hydrogen that is electrolyzed from fuel cell water to recapture oxygen (Sabatier reaction). Oxygen is added from the fuel cell water and reserve tanks. All of this means that a long-term mission is limited by the supplies of hydrogen and oxygen and water they bring along, or are delivered by resupply.Space vehicles can harness substantial energy from small reactors, fuel cells, and solar panels, but they cannot obtain any air or water in space.
Is the sun made out of hydrogen and helium?
It definitely runs on hydrogen, and its made of helium, as well. --- Yes, it is mainly made of hydrogen which it uses as a fuel. It fuses hydrogen nuclei together to form helium, producing huge amounts of energy through this nuclear fusion reaction. Helium is produced by this reaction. The most important fusion reaction is stars the size of our Sun, is the so called 'Proton - proton' reaction, which in summary, combines 4 nuclei of Hydrogen to produce one nucleus of Helium, plus two nuclei of Hydrogen, and positrons and gamma rays. Gamma rays get transformed inside the sun into less harmful electromagnetic radiations. There are other fusion reaction inside stars, which combine lighter atom nuclei into heavier nuclei, going up to producing carbon C and iron Fe nuclei.
You by yourself can move our planet?
Newton's Third Law of motion: Every action has an equal and opposite reaction. When we move forward(action) the earth moves backward(reaction). When we move backward(action) the earth moves forward(reaction).
Why might there be differences in reaction time between auditory and visual cues?
Simple reaction time studies show that RT to auditory stimuli is faster than visual stimuli. This is because the sensory process for light is more neurologically complex than for auditory cues. For light to be processed, it has a longer path to take in the brain, going all the way to the back of the brain to the occipital lobe and then back to the eyes. Auditory stimuli is processed in the ear then sent to the temporal lobe and back to the ear; a relatively shorter distance than the vision pathway. Reaction time to auditory cues in normal, healthy subjects is roughly 180 milliseconds for auditory cues and about 220 milliseconds.
How does caffeine affect reaction times?
Caffeine increases the reaction time to visual and auditory stimuli
What is an auditory stimalation?
Auditory stimulation is stimulation by sound. An example would be your reaction to someone sneaking up behind you and loudly clapping their hands. The stimulation would be the sound. Your reaction would probably be to become startled or jump.
How does space affect astronauts' reaction times?
Man, I don't know!
What is an auditory startle response?
The ASR is the change in behavior in reaction to either a surprise or prepared acoustic event. This change can be immediate or long lasting,
What is a stimuli?
A thing or event that evokes a specific functional reaction in an organ or tissue: "areas of the brain which respond to auditory stimuli".
How astronauts slow their spacecraft down?
Using Reaction Control Thrusters or Cold Gas Jets (small thrusters). The astronauts fire them in the opposite direction that the spacecraft is traveling and this thrust slows down the craft.
Why is reaction time important?
reaction time is important because you know how long it takes.
How do astronauts travel?
they travel in a very hevy space suit so the gravity dose not lift them Chemical reaction rockets.
Why is it important to stir H2O2 in the iodine clock reaction?
The motivation is to accelerate the reaction.
What are the body decomposition reaction?
The most important body decomposition reaction is the digestion of foods.
Why are the product of the light reaction of photosynthesis important?
They are used to produce sugar during the dark reaction
