How far is it from Earth to space?
about 62 miles
There’s also fuel problem too. The shortest distance between Earth and space is about 62 miles (100 kilometers) straight up, which by general accord is where the planet’s boundary ends and suborbital space begins.
How big is the space?
about 93 billion light-years
The proper distance—the distance as would be measured at a specific time, including the present—between Earth and the edge of the observable universe is 46 billion light-years (14 billion parsecs), making the diameter of the observable universe about 93 billion light-years (28 billion parsecs).
Why is space black?
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.
Is space infinite or finite?
The observable universe is finite in that it hasn’t existed forever. It extends 46 billion light years in every direction from us. (While our universe is 13.8 billion years old, the observable universe reaches further since the universe is expanding). The observable universe is centred on us.
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.
Why don’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. Since there is virtually nothing in space to scatter or re-radiate the light to our eye, we see no part of the light and the sky appears to be black.
What is the importance of space exploration in human life?
Human Space Exploration. Human space exploration helps to address fundamental questions about our place in the Universe and the history of our solar system. Through addressing the challenges related to human space exploration we expand technology, create new industries, and help to foster a peaceful connection with other nations.
Why does NASA want to go to space?
The Lagrange point on the far side of the Earth-Moon system, called L2, also provides a “radio silence” zone for astronomical observations. Missions to translunar space will give NASA and its partners the opportunity to develop tools and operational techniques to support decades of future exploration, while remaining in relative proximity to Earth.
Does the universe have a purpose?
Our intentional stance leads us to believe that the universe itself has a purpose, inferring it to be the product of a deliberate, creative designing agent—an agent just like us, only immensely more powerful.
What is the purpose of the International Space Station?
The International Space Station serves as a national laboratory for human health, biological, and materials research, as a technology test-bed, and as a stepping stone for going further into the solar system. On the International Space Station we will improve and learn new ways to ensure astronauts are safe,…
