Because it is moving at about 17,000 mph (28,000 km/h), the orbiter hits air molecules and builds up heat from friction (approximately
3000 degrees F, or 1650 degrees C
).
Does temperature affect rocket launches?
A rocket can't fly into any smoke clouds above the launch pad. Temperatures aren't frequently freezing in Cape Canaveral, but
air temperatures or cloud temperatures above the site can dip below freezing
. If that's the case, the launch can't go on as planned.
Is it cold in a spaceship?
While we generally think of space as being very cold,
spacecraft are exposed to extremes of temperature, from extremely hot on the sunward side to extremely cold on the shadow side or in the outer solar system
.
How do astronauts survive the extreme temperatures of space?
“In space, it's a matter of insulation. Just as your blanket keeps your body heat in so you stay warm in bed,
NASA space suits have insulation systems as well as heaters
.” How Stuff Works finds that “Spacesuits designed by NASA for Apollo astronauts used heating elements to protect astronauts from extreme cold.
Can rubber survive in space?
During reentry into the atmosphere, friction caused by air moving along the outside of a spacecraft makes temperatures extremely high.
Without the right rubber technologies, astronauts wouldn't survive
.
Can an astronaut survive reentry?
Even if it is possible, it won't happen
; since the astronaut was in a space pod, his or her suit probably wasn't designed for re-entry. A space suit strong enough to withstand re-entry would be so bulky and reinforced, it might as well be a small spaceship.
What do the letters in NASA stand for?
Each NASA center works on different parts of NASA's missions. NASA stands for
National Aeronautics and Space Administration
. NASA was started on October 1, 1958, as a part of the United States government. NASA is in charge of U.S. science and technology that has to do with airplanes or space.
How much do astronauts get paid?
According to NASA, civilian astronauts are awarded a pay grade of anywhere from GS-11 to GS-14, so the income range is relatively wide.
Starting salaries begin at just over $66,000 a year. Seasoned astronauts, on the other hand, can earn upward of $144,566 a year
.
What weather do you need to launch rocket?
The weather criteria are as follows: –
Cloud coverage of 4/8 or less below 8,000 feet and a visibility of 5 miles or greater required
. – The peak crosswind cannot exceed 15 knots, 12 knots at night. If the mission duration is greater than 20 days, the limit is 12 knots, day and night.
Does rain stop a rocket launch?
Clouds and rain
Even if there is no lightning around the launch pad,
any type of precipitation can force a launch to be scrubbed
. This usually comes in the form of rain as it is rare for any type of frozen precipitation to fall along the coast of Florida.
How will the wind affect the rocket after it is launched?
How will the wind affect the rocket after it is launched?
The wind will help the launch achieve a higher altitude
. The rocket may be blown off course.
What happens if you bleed in space?
In space,
blood can splatter even more than it usually does on Earth, unconstrained by gravity
. Or it can pool into a kind of dome around a wound or incision, making it hard to see the actual trauma. (Fun fact: If you are bleeding more than 100 milliliters per minute, you are probably doomed.
Why is space cold if the sun is hot?
Space is the ultimate thermos
The sun's radiation may travel through it, but there are no molecules or atoms to absorb that heat
. Even when a rock is heated above 100°C by the sun's radiation, the space around it will not absorb any temperature because of the same reason.
How do they poop in space?
To poop, astronauts
lift the toilet lid and sit on the seat
— just like here on Earth. But this toilet starts suctioning as soon as the lid is lifted to prevent things from drifting away — and to control the stink.
How hot is the moon?
The moon's temperature can reach a boiling
250° Fahrenheit (120° Celsius or 400 Kelvin)
during lunar daytime at the moon's equator, according to NASA.
What does space smell like?
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 …
Do astronauts feel cold in space?
In space, nothing is radiating back at you and
you will get cold if the sun isn't shining on you
, but it shouldn't take much insulation to make it so the outside of your suit is much cooler than the inside, so your losses by radiation will be much smaller.
Can an astronaut survive a solar storm?
What is the danger of a solar storm in space? Very high-energy particles, such as those carried by CMEs, can cause radiation poisoning to humans and other mammals.
They would be dangerous to unshielded astronauts
, say, astronauts traveling to the moon. Large doses could be fatal.
Can Wood survive in space?
If a wooden satellite were orbiting in space 300 miles up, this excess charge might simply dissipate into the surrounding plasma. But
up in higher orbits, the poor conductivity of wood could be a disaster
. Wood would also give off gases as it aged, which might damage delicate sensors or other equipment.
Does metal rust in space?
Aluminium and stainless steel form a protective oxide layer and won't corrode, but silver and iron corrode quickly in low orbit
. In deep space, however, the lack of oxygen means that corrosion does not occur.
Why does reentry have to be so fast?
To skim the Earth's atmosphere in orbit
, your spacecraft has to travel at least as fast as 7.8 km / second, or about 17,500 mph. The Earth itself, with its atmosphere, is spinning eastward below you, at around 1,000 mph. So, you can reduce your re-entry speed by orbiting in the same direction that the Earth spins.
Why is it so difficult to leave Earth's atmosphere?
Earth's gravity is strong enough to hold onto its atmosphere and keep it from drifting into space
.
When the astronaut turns off the engines what will the rocket do?
A space ship's momentum will continue to carry it forward indefinitely at a constant speed
after the engines are turned off.
Who was the first human in space?
Yuri Gagarin
from the Soviet Union was the first human in space. His vehicle, Vostok 1 circled Earth at a speed of 27,400 kilometers per hour with the flight lasting 108 minutes.
Who owns NASA?
That's because NASA isn't a private or publicly-owned company. Instead, it's an official agency of
the U.S. government
. That means it's technically owned by the United States and receives government funding just like the Department of Justice, Department of Education, National Park Service, etc.
Is NASA still a thing?
The National Aeronautics and Space Administration (NASA /ˈnæsə/) is
an independent agency of the U.S. federal government
responsible for the civilian space program, as well as aeronautics and space research.
