Sound does not travel at all in space
. The vacuum of outer space has essentially zero air. Because sound is just vibrating air, space has no air to vibrate and therefore no sound. If you are sitting in a space ship and another space ship explodes, you would hear nothing.
How fast does sound travel in space?
The speed of sound in a vacuum is
zero meters per second
, as sound cannot travel in a vacuum. Sound is a wave, which means it spreads through the vibration of particles in a medium, such as water or air. Since a vacuum is empty space, there is no medium for the sound to travel through.
Do we age faster in space?
Scientists have recently observed for the first time that, on an epigenetic level,
astronauts age more slowly during long-term simulated space travel than they would have if their feet had been planted on Planet Earth.
How long will footprints on the moon last?
An astronaut’s footprint can last
a million years
on the surface of the moon. It may have been decades since we last set foot on the moon, but its surface is still marked with the historic footprints of the 12 astronauts who stomped across it. That’s because the moon has no atmosphere.
Can you smell a fart in space?
In space, no one can hear you fart (but
they can smell it
). They can! Zero gravity could even help them to travel, if the aroma was spreading through a virtual vacuum. Smells travel by the movement of individual aroma molecules.
Is fire possible 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 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 …
How long is 1 year in space?
**One year in space would be
365 days
/1 year on earth…..
How long is 1 hour in space?
One hour on Earth is
0.0026 seconds
in space.
How cold is it in space?
Hot things move quickly, cold things very slowly. If atoms come to a complete stop, they are at absolute zero. Space is just above that,
at an average temperature of 2.7 Kelvin (about minus 455 degrees Fahrenheit)
.
Is the US flag still on the Moon?
Images taken by a Nasa spacecraft show that
the American flags planted in the Moon’s soil by Apollo astronauts are mostly still standing
. The photos from Lunar Reconaissance Orbiter (LRO) show the flags are still casting shadows – except the one planted during the Apollo 11 mission.
What is the temperature on the Moon?
The average temperature on the Moon (at the equator and mid latitudes) varies from
-298 degrees Fahrenheit (-183 degrees Celsius), at night, to 224 degrees Fahrenheit (106 degrees Celsius) during the day
.
Why did the Moon stop spinning?
Gravity from Earth pulls on the closest tidal bulge, trying to keep it aligned. This creates tidal friction that slows the moon’s rotation
. Over time, the rotation was slowed enough that the moon’s orbit and rotation matched, and the same face became tidally locked, forever pointed toward Earth.
What foods are not allowed in space?

Can astronauts smoke in space?
We know that
NASA astronauts are not allowed to smoke or drink while they’re working up there
. Rae Paoletta. SpaceX launched tardigrades and baby squid toward the space station on Thursday..
How do astronauts wipe their bum?
Today, astronauts at the International Space Station go to the bathroom into a little plate-sized toilet hole, and
a fan vacuum sucks their excrement away
and a separate funnel equipped with a fan suction their pee away.
Do astronauts menstruate in space?
Turns out
menstruating in space is not much different than it is on Earth
. Women have been living and working in space for decades now, and with no issues. But here’s the problem: all available data on periods in space pertain to short-duration missions.
Is there wind in space?
The solar wind streams plasma and particles from the sun out into space
. Though the wind is constant, its properties aren’t. What causes this stream, and how does it affect the Earth?
How does the sun burn if there is no oxygen in space?
Since there is a vacuum in space, there is no oxygen there, so how does the sun burn?
It releases energy because of nuclear fusion in it’s core where hydrogen turns into helium
. That is how the sun becomes hot amd bright.
Why can’t you see the sun in space?
In space or on the Moon
there is no atmosphere to scatter light
. The light from the sun travels a straight line without scattering and all the colors stay together. Looking toward the sun we thus see a brilliant white light while looking away we would see only the darkness of empty space.
Why can’t you see the stars in space?
The stars aren’t visible
because they are too faint
. The astronauts in their white spacesuits appear quite bright, so they must use short shutter speeds and large f/stops to not overexpose the pictures. With those camera settings, though, the stars don’t show up.
What happens if you take your helmet off in space?
Removing the helmet would leave
permanent ear damage and the lack of oxygen would damage many organs
. Also, if the astronaut is in a very cold part of the universe, the astronaut would start to freeze. While low pressure would lead to the boiling of his blood, saliva and in the end organs.
How long does it take to get from Earth to the Moon?
It takes about
3 days
for a spacecraft to reach the Moon. During that time a spacecraft travels at least 240,000 miles (386,400 kilometers) which is the distance between Earth and the Moon. The specific distance depends on the specific path chosen.
How much is a ticket to Mars?
Elon Musk: A Round-Trip Ticket to Mars Will Cost Just
$100,000
.
Is it true that 1 hour in space is 7 years on Earth?
The first planet they land on is close to a supermassive black hole, dubbed Gargantuan, whose gravitational pull causes massive waves on the planet that toss their spacecraft about. Its proximity to the black hole also causes an extreme time dilation, where
one hour on the distant planet equals 7 years on Earth.
