A. Like any other object in low-Earth orbit, a Space Shuttle must reach speeds of about
17,500 miles per hour
(28,000 kilometers per hour) to remain in orbit.
How fast was the shuttle to the moon?
By far, the fastest mission to fly past the Moon was NASA’s New Horizons Pluto mission. This mission had a speedy launch, with its Atlas V rocket accelerating it to a a speed of about
16.26 km per second
(58,536 km/h; 36,373 mph). At this rate, it only took 8 hours and 35 minutes for it to get to the Moon from Earth.
Is space always dark?
How dark does space get? If you get away from city lights and look up, the sky between the stars appears very dark indeed. Above the Earth’s atmosphere, outer space dims even further, fading to an inky pitch-black. And yet even there,
space isn’t absolutely black
.
How long does it take to get back to Earth from 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.
How long did it take for Neil Armstrong to get to the moon?
| Mission duration 8 days, 3 hours, 18 minutes, 35 seconds | Spacecraft properties | Spacecraft Apollo CSM-107 Apollo LM-5 | Manufacturer CSM: North American Rockwell LM: Grumman | Launch mass 100,756 pounds (45,702 kg) |

Could the human body survive light speed?
In 1947 humans first surpassed the (much slower) speed of sound, paving the way for the commercial Concorde jet and other supersonic aircraft. So will it ever be possible for us to travel at light speed? Based on our current understanding of physics and the limits of the natural world,
the answer, sadly, is no.
Can a human travel at the speed of light?
Can we travel at the speed of light?
No, we cannot travel at the speed of light
. You see, if an object travels at the speed of light, its mass will increase exponentially!
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.
How cold is space?
Far outside our solar system and out past the distant reachers of our galaxy—in the vast nothingness of space—the distance between gas and dust particles grows, limiting their ability to transfer heat. Temperatures in these vacuous regions can plummet to about
-455 degrees Fahrenheit (2.7 kelvin)
.
Why is the sun so hot but it’s cold in space?
The reason is obvious:
sunlight contains energy, and in near-Earth space, there is no atmosphere to filter that energy, so it’s even more intense than it is down here
. Now, on Earth, if you put something out in the sun, it warms up.
What planet takes 7 years to get to?
| Spacecraft Target Time | Galileo Jupiter 6 years | Messenger Mercury 6.5 years | Cassini Saturn 7 years | Voyager 1 & 2 Jupiter; Saturn; Uranus; Neptune 13,23 months; 3,4 years; 8.5 years; 12 years |

How long is a trip to Mars?
The trip to Mars will take
about seven months
and about 300 million miles (480 million kilometers). During that journey, engineers have several opportunities to adjust the spacecraft’s flight path, to make sure its speed and direction are best for arrival at Jezero Crater on Mars.
How long is the trip to the sun?
On average, the sun is 93 million miles from the earth. It would take
1,430,769 hours
to drive there at 65 miles per hour. It would take 59,615 days to drive there at 65 miles per hour. It would take 163 years to drive there.
Who owns the Moon?
The short answer is that
no one owns the Moon
. That’s because of a piece of international law. The Outer Space Treaty of 1967, put forward by the United Nations, says that space belongs to no one country.
Is the American 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.
How many times humans have landed on Moon?
Six missions
landed humans on the Moon, beginning with Apollo 11 in July 1969, during which Neil Armstrong became the first person to walk on the Moon. Apollo 13 was intended to land; however, it was restricted to a flyby due to a malfunction aboard the spacecraft. All nine crewed missions returned safely to the Earth.
How fast is the speed of dark?
Darkness travels at the speed of light
. More accurately, darkness does not exist by itself as a unique physical entity, but is simply the absence of light. Any time you block out most of the light – for instance, by cupping your hands together – you get darkness.
What is quicker than the speed of light?
Albert Einstein’s special theory of relativity famously dictates that
no known object can travel faster than the speed of light in vacuum
, which is 299,792 km/s.
Is time travelling possible?
In Summary:
Yes, time travel is indeed a real thing
. But it’s not quite what you’ve probably seen in the movies. Under certain conditions, it is possible to experience time passing at a different rate than 1 second per second.
How long would it take to get to Pluto traveling at the speed of light?
So let me give you some context. Light itself takes
4.6 hours
to travel from the Earth to Pluto. If you wanted to send a signal to Pluto, it would take 4.6 hours for your transmission to reach Pluto, and then an additional 4.6 hours for their message to return to us. Let’s talk spacecraft.
Is warp engine possible?
“
None of the physically conceivable warp drives can accelerate to speeds faster than light
,” Bobrick says. That is because you would require matter capable of being ejected at speeds faster than light—but no known particles can travel that fast.
How close is humanity to light speed?
We can never reach the speed of light
. Or, more accurately, we can never reach the speed of light in a vacuum. That is, the ultimate cosmic speed limit, of 299,792,458 m/s is unattainable for massive particles, and simultaneously is the speed that all massless particles must travel at.
What is the black in space?
Because space is a near-perfect vacuum — meaning it has exceedingly few particles — there’s virtually nothing in the space between stars and planets to scatter light to our eyes. And
with no light reaching the eyes
, they see black.
What does space smell like?
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’.
Will a dead body decompose in space?
Halting decomposition
And bacteria from the gut would still devour the soft tissues
. But these bacteria need oxygen to function properly and so limited supplies of air would significantly slow down the process.
