Can smoke exist in space?

Smoke and air can exist in space, they just are not found in huge clumps because the atoms want to dispurse to reduce pressure.

Can there be fire and smoke in space?

Fires can't start in space itself because there is no oxygen – or indeed anything else – in a vacuum. Yet inside the confines of spacecraft, and freed from gravity, flames behave in strange and beautiful ways. They burn at cooler temperatures, in unfamiliar shapes and are powered by unusual chemistry.

Does space have smoke?

But detecting smoke in space isn't quite so simple. Smoke detectors work by looking for particles in the air that are about the same size as the particles normally found in smoke. However, a 1996 NASA Glenn study showed that smoke particles in space are bigger than those on Earth.

What is smoke 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.

Did astronauts smoke in space?

A number of Gemini and Apollo astronauts were also smokers, but as far as I know, they all quit before flying. It's been reported that some cosmonauts have been smokers, even fairly recently.

CANNABIS IN SPACE!

Does space smell burnt?

A succession of astronauts have described the smell as '… a rather pleasant metallic sensation ... [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'.

Why astronauts do not stink in space?

We can't smell space directly, because our noses don't work in a vacuum. But astronauts aboard the ISS have reported that they notice a metallic aroma – like the smell of welding fumes – on the surface of their spacesuits once the airlock has re-pressurised.

What does fire look like in 0 gravity?

In zero gravity, where heat does not rise, candle flames take on a uniform oval shape instead of the teardrop one seen on Earth. In space, because there is no up and down, the flame shapes look similar even when inverted. Upright, the flame is primarily next to and above the wick, where the fuel comes in.

Do drugs work in space?

Astronauts on long space missions may not be able to take paracetamol to treat a headache or antibiotics to fight infection, a study has found. Scientists at the Johnson Space Center have shown that the effectiveness of drugs declines more rapidly in space.

Can you get burnt in space?

Ultraviolet (UV) radiation from the sun is largely absorbed by the Earth's atmosphere and never reaches its surface, but a human unprotected in space would suffer sunburn from UV radiation within seconds.

Does space actually have a smell?

Astronaut Thomas Jones said it "carries a distinct odor of ozone, a faint acrid smell…a little like gunpowder, sulfurous." Tony Antonelli, another space-walker, said space "definitely has a smell that's different than anything else." A gentleman named Don Pettit was a bit more verbose on the topic: "Each time, when I ...

Can you burn a candle in space?

But what happens when you light a candle, say, on the International Space Station (ISS)? "In microgravity, flames burn differently—they form little spheres," says Williams. Flaming spheres on the ISS turn out to be wonderful mini-labs for combustion research.

Can astronauts drink alcohol in space?

Alcohol is prohibited aboard the International Space Station due to the impact it can have on the Environmental Control and Life Support System (ECLSS). A 1985 NASA report on extended spaceflight predicted that alcohol would be missed, but would only become common in stable settlements.

Can a gun still fire in space?

Yes. Bullets carry their own oxidising agent in the explosive of the cartridge (which is sealed, anyway) so there's no need for atmospheric oxygen to ignite the propellant.

Can you burp in space?

In space, there is no gravity to pull things straight down, so the gas and liquids in the astronauts' stomachs don't seperate. This means the gas can't come back up to create a burp! Or, at least, a burp like we would known on Earth.

How does the Sun burn if space has no air?

Answer: The Sun does not "burn", like we think of logs in a fire or paper burning. The Sun glows because it is a very big ball of gas, and a process called nuclear fusion is taking place in its core.

Can you get an erection in space?

Relatedly, your boner will probably suffer. Blood flow is essential to get an erection, and lower blood pressure would mean it would be harder to get an erection — and harder to keep it going. There's another issue that might make your stiffy collapse — testosterone levels fall while in space.

Do Tears work in space?

While the zero gravity atmosphere does not have an impact on tears forming, it has an affect on if they fall, and they don't. The water that builds up in you eye from crying will stay there until the bubble gets so big it moves to another spot on your face, or it's removed.

What Cannot go in the space?

Common items like salt and bread are banned from the International Space Station due to fears that they'll send floating pieces everywhere and potentially damage space equipment or accidentally get inhaled by astronauts. Basic eating, sleeping, and showering habits must also be modified.

Why does fire turn blue in space?

In space, hot and cold air weigh the same: nothing. Heated air just expands outward in a sphere. Because the air doesn't rush away in one direction (up) like on Earth, the fire burns hotter and doesn't produce as much smoke and soot, making the whole flame blue.

Which fire is invisible?

Ethanol fires are nearly invisible and burn incredibly hot. The fire “flashed” almost immediately filling the nearly 1,500 sq. ft. room with invisible flames and creating intensely high heats.

Can fire burn 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.

What does the Moon smell like?

After walking on the Moon astronauts hopped back into their lunar lander, bringing Moon dust with them. They were surprised, and perplexed, to find that it smelled like spent gunpowder.

What is the actual Colour of space?

It turns out that if the universe was infinitely large and infinitely old, then we would expect the night sky to be bright from the light of all those stars. Every direction you looked in space you would be looking at a star. Yet we know from experience that space is black!

Can you hear sound in space?

No, there isn't sound in space.

This is because sound travels through the vibration of particles, and space is a vacuum. On Earth, sound mainly travels to your ears by way of vibrating air molecules, but in near-empty regions of space there are no (or very, very few) particles to vibrate – so no sound.
