Question: Why Is Fire In Space Bad?

Can things catch on fire in space?

In space, of course, you can’t have any fires because there isn’t any oxidizer (i.e.

oxygen) to sustain the combustion process.

Do female astronauts wear bras in space?

Women don’t wear bras primarily for support, they’re also worn as a thick layer of coverage so detailed outlines are not visible. Although the support portion may not be necessary in space, in a professional setting the extra layer of coverage may still be preferred by some.

Does a body decay in space?

If you do die in space, your body will not decompose in the normal way, since there is no oxygen. If you were near a source of heat, your body would mummify; if you were not, it would freeze. If your body was sealed in a space suit, it would decompose, but only for as long as the oxygen lasted.

How much do astronauts get paid?

Astronauts’ annual salaries are determined using a government pay scale, and starting out, typically fall under two grades: GS-12 and GS-13. According the US government’s 2020 pay scales and a NASA job listing, a civilian astronaut in 2020 can earn between $66,167 and $161,141 per year.

Can fire burn underwater?

Commonly a fifty-fifty mixture of rust and aluminum powder, thermite requires the high temperatures of a burning strip of magnesium to light, but once it gets started it’s almost impossible to extinguish. It can burn through pavement, melt through engine blocks, and even stay on fire underwater.

Would a grenade explode in space?

2 Answers. Yes, it would explode. Most hand grenades are nowadays triggered chemically, electrically or contain a fuze enclosed within the assembly, so they don’t require atmospheric oxygen to ignite, are watertight and otherwise more reliably go off at a preset time since activation.

Is Cold Fire Possible?

Fire is a self-sustaining exothermic chemical reaction. If you’re not a chemist, “exothermic” means that it produces heat. To have a cold fire, you would need some gas-phase reaction that absorbs heat (endothermic), and gets faster at low temperature, with a negative activation energy. … A cold fire is not possible.

Can fire burn in vacuum?

No, a fire can’t burn in a vacuum, because oxygen which is a crucial component to facilitate combustion is not present in a vacuum.

Can fire burn on Mars?

The Martian atmosphere is 1/100th of the density of the Earth’s (i.e. 1/100th as much gas) and 95% of it is carbon dioxide, which is used to make fire extinguishers. … With no oxygen, fire cannot burn.

How does fire burn in space without oxygen?

The fire you mentioned burning in absence of oxygen, will be only in the ‘Sun’, that is by nuclear fusion of hydrogen molecules/Atoms, to Helium molecules/Atoms, by self sustaining atomic level nuclear fusion, which needs only very high temp.

Why does your head explode in space?

Why does your head explode in space, disappointingly, the answer is that, it doesn’t. … But their heads didnt explode, the reason for this is because there are too kinds of pressures, normal pressure and vacuum. Vacuum pressure is not strong enough to cause a head to explode, but it can still kill you.

Why is fire dangerous in space?

Fire is a different beast in space than it is on the ground. When flames burn on Earth, heated gases rise from the fire, drawing oxygen in and pushing combustion products out. In microgravity, hot gases don’t rise. So an entirely different process, called molecular diffusion, drives flame behavior.

What would fire look like in space?

Without gravity, hot air expands but doesn’t move upward. The flame persists because of the diffusion of oxygen, with random oxygen molecules drifting into the fire. Absent the upward flow of hot air, fires in microgravity are dome-shaped or spherical—and sluggish, thanks to meager oxygen flow.

What does space smell like?

sweet-smelling welding fumes’, ‘burning metal’, ‘a distinct odour of ozone, an acrid smell’, ‘walnuts and brake pads’, ‘gunpowder’ and even ‘burnt almond cookie’. Some astronauts have likened the smells of space to walnuts.

What happens if you breathe in space?

The vacuum of space will pull the air from your body. So if there’s air left in your lungs, they will rupture. Oxygen in the rest of your body will also expand. You’ll balloon up to twice your normal size, but you won’t explode.

How many monkeys died in space?

A previous monkey, Albert I, died when the V-2 rocket failed before reaching peak altitude. Two other monkeys, Albert III and IV, also died when their rockets failed. A mouse launched on Aug. 15, 1950, attained an altitude of 85 miles (137 km), but died when the rocket disintegrated due to parachute failure.

Is white fire hotter than blue fire?

When temperatures approach 2,400º F to 2,700º F, flames appear white. … The color blue indicates a temperature even hotter than white. Blue flames usually appear at a temperature between 2,600º F and 3,000º F. Blue flames have more oxygen and get hotter because gases burn hotter than organic materials, such as wood.

How many dead bodies are in space?

As of 2020, there have been 15 astronaut and 4 cosmonaut fatalities during spaceflight. Astronauts have also died while training for space missions, such as the Apollo 1 launch pad fire which killed an entire crew of three. There have also been some non-astronaut fatalities during spaceflight-related activities.

What would happen if u shoot a gun in space?

On Earth, gravity eventually pulls the bullet down, even if it doesn’t hit anything — or anyone. In space, where there is no gravity, your bullet could keep moving forever as long as it doesn’t hit something — like an asteroid or a planet.

Can a fire be lit on the moon?

“The fuel and oxidizer in a match head would cause the tip to burn, but not for long because of lack of oxygen.” And in the moon’s complete lack of atmosphere, a match cannot ignite at all — explanation enough for why Neil Armstrong didn’t celebrate his step onto the lunar surface with a candlelight dinner.

Are there germs in space?

To the surprise of many scientists, many missions to outer space over the past several decades have revealed that over 250 different species of bacteria and fungi can not only survive, but even thrive in the harsh conditions of outer space.
