Can astronauts see the sun in space?
The International Space Station travels at a brisk 17,100 miles per hour. That means it orbits Earth every 90 minutes—so it sees a sunrise every 90 minutes. Thus, every day, the residents of the ISS witness 16 sunrises and 16 sunsets.
Is it dark in deep space?
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. The universe has a suffused feeble glimmer from innumerable distant stars and galaxies. This artist’s illustration shows NASA’s New Horizons spacecraft in the outer solar system.
Why did John Glenn’s wife stutter?
Annie Glenn’s stutter was hereditary: Homer Castor, her father, also stuttered. The communication disorder would stay with Annie her whole life, but at age 53, she was able to greatly improve her speech via a three-week treatment course at Hollins Communications Research Institute in Roanoke, Virginia.

Did Alan Shepard walk on the moon?
Derry’s Alan Shepard, who was among the first seven NASA astronauts, was the first American in space and the fifth to walk on the moon.
Did John Glenn go into space?
Nearly four decades after he became the first American to orbit the Earth, Senator John Hershel Glenn, Jr., is launched into space again as a payload specialist aboard the space shuttle Discovery. At 77 years of age, Glenn was the oldest human ever to travel in space.
Did Gordo Cooper cheat on his wife?
Did Gordon Cooper cheat on his wife, Trudy Cooper? Yes. In fact, his wife Trudy had left him four months prior to the astronaut selection process. However, during the selection interviews, he lied and said that he and Trudy had a healthy and stable marriage.
How old was John Glenn when he went to space the first time?
Are any Mercury 7 astronauts alive?
Glenn became the first American in orbit in 1962, and flew on the Space Shuttle Discovery in 1998 to become, at age 77, the oldest person to fly in space. He was the last living member of the Mercury Seven when he died in 2016 at the age of 95.
What went wrong with Friendship 7?
There were several scary moments aboard Friendship 7. Glenn aboard Friendship 7 on February 20, 1962. During his second orbit, mission control noticed a sensor was issuing a warning that Friendship 7’s heat shield and landing bag were not secure, putting the mission, and Glenn in danger.
Did Gordon Cooper get divorced?
According to a NASA biography of Mr. Cooper prepared for the 40th anniversary of his Gemini flight, last year, that marriage ended in divorce, and he married Suzan Taylor in 1972.
What almost happened to John Glenn in space?
The rocket could explode on the pad, some catastrophic failure could stop Glenn from reaching orbit, the reentry system could fail leaving Glenn orbiting the Earth in a capsule-shaped coffin, the spacecraft could break up during reentry, he could drown after splashdown just about every phase of the flight was …
How did they decide who stepped on the moon first?
Most people assume mission Commander Neil Armstrong was always NASA’s first choice to walk on the moon because of his seniority. According to Aldrin, NASA decided Armstrong should walk on the moon first because it was “symbolic.”
Did Alan Shepard and John Glenn not like each other?
Not only did their personalities clash, but Glenn was outspoken about how he disagreed with some of the astronauts’ alleged infidelity, which would have included Shepard. Things between them were likely only made worse when they were selected as lead astronaut and alternate for the first Mercury flight.
Who was the first person to set foot on the moon?
How does sound propagate through a medium?
Sound is a type of energy made by vibrations. These vibrations create sound waves which move through mediums such as air, water and wood. When an object vibrates, it causes movement in the particles of the medium. This movement is called sound waves, and it keeps going until the particles run out of energy.
Why can sound not travel through space?
Sound waves are travelling vibrations of particles in media such as air, water or metal. So it stands to reason that they cannot travel through empty space, where there are no atoms or molecules to vibrate.
How many hours is a day in space?
Is it always dark on the moon?
The ‘dark side’ of the Moon refers to the hemisphere of the Moon that is facing away from the Earth. In reality it is no darker than any other part of the Moon’s surface as sunlight does in fact fall equally on all sides of the Moon.
What do astronauts do 16 times a day?
We orbit the Earth about once every 90 minutes. During the orbit of the Earth we are in daylight for about 45 minutes and darkness for about 45 minutes. That means the sun will rise and set 16 times a day.
In which medium does sound not propagate?
Sound needs a material medium for their propagation like solid, liquid or gas to travel because the molecules of solid, liquid and gases carry sound waves from one point to another. Sound cannot progress through the vacuum because the vacuum has no molecules which can vibrate and carry the sound waves.
Which satellite is near to Sun?
Parker Solar Probe
Does life exist on the moon?
The moon may have more water and oxygen than Earth and an oxygen exosphere. Thought to have a subsurface liquid water ocean due to tidal heating or geothermal activity. Free molecular hydrogen (H2) has been detected, providing another potential energy source for life.
Does space have a smell?
As it turns out, space actually does have a distinct odor. Astronauts returning from space claim that their suits smell, in a word, burnt. The lingering scent of space is “acrid” and “metallic,” reminding the astronauts of charred meat or welding fumes.
Can anything touch the sun?
NASA’s Parker Solar Probe is the first-ever mission to “touch” the Sun. The spacecraft, about the size of a small car, travels directly through the Sun’s atmosphere –ultimately to a distance of bout 4 million miles from the surface.
Why is space silent?
In space, no one can hear you scream. This is because there is no air in space – it is a vacuum. Sound waves cannot travel through a vacuum. ‘Outer space’ begins about 100 km above the Earth, where the shell of air around our planet disappears.
What medium does sound travel best through?
How does medium affect sound?
The density of a medium is the second factor that affects the speed of sound. Density describes the mass of a substance per volume. A substance that is more dense per volume has more mass per volume. If a material is more dense because its molecules are larger, it will transmit sound slower.
Has anyone flew to the sun?
Icarus, in Greek mythology, son of the inventor Daedalus who perished by flying too near the Sun with waxen wings. See Daedalus.
Can you see stars in space during the day?
Stars can be seen in the daytime sky, but this is a bit of a cheat. Stars, along with the brighter planets already mentioned, can be seen with the unaided human eye in a daytime sky (that is, when the sun is above the horizon) normally only during a total solar eclipse.
What does sound travel through the slowest?
As a rule sound travels slowest through gases, faster through liquids, and fastest through solids. The speed of light as it travels through air and space is much faster than that of sound; it travels at 300 million meters per second or 273,400 miles per hour.
Do sound waves travel forever?
First, let’s think about why sound does not travel forever. Sound cannot travel through empty space; it is carried by vibrations in a material, or medium (like air, steel, water, wood, etc). So, the sound wave gets smaller and smaller until it disappears.
