Watch the earth roll https://www.nasa.gov https://spaceofficial.com SPACE & UNIVERSE Network The International Space Station - ISS - circles the earth at 240 miles above the planet, on the edge of space in low earth orbit. The station is crewed by NASA astronauts as well as Russian Cosmonauts and a mixture of Japanese, Canadian and European astronauts as well. Please Standby mode (Bluescreen) The signal is temporarily lost from the international space station, live on UStream.tv The ISS passes into the dark side of the earth for roughly half of each of its 90-minute orbits. As the Space Station passes into a period of night every 45 mins video is unavailable - during this time, and other breaks in transmission recorded footage is shown when back in daylight earth will recommence.

THE REASON WHY I AM A FLAT-EARTHER 1-We don't see —and nobody else does— any curvature in the "horizontal" horizon, and no one can prove it. 2-We don't feel —and nobody else does— that the Earth moves. If the Earth spins 1,000 miles p/h, and is curling, hurling, swirling, twirling and whirling all together with the Sun, the planets and the Milky Way throughout the expanding universe at the speed of 66,600 miles p/h (say what!), we would feel her movement, and not even a hair from our head moves. 3-If we travel from U.S.A. to China in a full moon night, by the time we arrive to China we would see the other side of the Moon, for being on the other side of the Earth. But it's not so. Instead, we notice that the Moon rotates like a disc. And that's not all: it seems that the Moon, if we don't make a move, neither she does whatsoever. 4-If we observe the Moon from 6:00 AM to 6:00 PM, we don't notice any movement. But the Earth has already rotated half way. And I bet that if we do a little effort and stay observing her for the next 12 hours of the night, we would see that she doesn't move at all. 5-We see the Sun and the Moon exactly the same size. Besides, we have seen the Sun and the Moon between the clouds, and many people are uploading their home videos to YT as empirical evidences. 6-Many videos in YT are showing Moon eclipses when the Sun hasn't set yet. 7-If we are in a house, and the Sun is rising, and we go to a room in the opposite side from where the Sun is rising and we see it illuminated, it's because there might be a reflector up in the sky —as photographers do to illuminate the 3D objects to get the best picture. 8-Rain, snow, hail, lightning and thunder, might generate from a solid surface because it's absurd for them to be formed from within a cloud, that is synonym of smoke, gas and vapor. It is impossible for this cloud-smoke-vapor-gas to hold tons of water that rains all over the Earth. 9-If gravity is so powerful to sustain without falling off the entire infrastructure of Australia (steel bridges and heavy concrete buildings), which is upside down in the southern hemisphere, would not let mosquitoes, ants and fleas to move freely, and much less, to allow the wind to blow away a dust particle. 10-Many videos in YT are about people asking the airlines for trips crossing Antarctica, from Australia to Argentina or Chile (or vice versa), and the airlines reply is that there are none.

This series depicts a hypothetical 6-mile diameter asteroid impacting Earth 20 miles off the coast of New York, starting out in the asteroid belt, where a larger asteroid is bumped out of its orbit by a smaller impactor. Over time, this asteroid eventually crosses paths with Earth. The impact completely wipes out most of New York, and leaves the majority of the east coast in flames. An initial dome-shaped shock wave propagates outward from the impact, flattening everything in its path. Debris from the impact is scattered into the upper atmosphere & beyond, some of it achieving a temporary earth orbit. Over time, some of that material forms rings around the earth which would gradually vanish as that material either falls back and burns up in the atmosphere as shooting stars, or travels further out into a space, leaving Earth. This was created at Radical 3D for the Animal Planet miniseries, "Animal Armageddon".

An asteroid doesn't need to be massive to cause serious damage. The Chicxulub asteroid that wiped out the dinosaurs is estimated to have been about 6 miles in diameter. That may sound like a pretty big space rock, but relative to Earth it's pretty tiny. But what's the likelihood of an asteroid of that size coming into contact with Earth again? The following is from NASA's website: "Every day, Earth is bombarded with more than 100 tons of dust and sand-sized particles. About once a year, an automobile-sized asteroid hits Earth's atmosphere, creates an impressive fireball, and burns up before reaching the surface. Every 2,000 years or so, a meteoroid the size of a football field hits Earth and causes significant damage to the area. Only once every few million years, an object large enough to threaten Earth's civilization comes along. Impact craters on Earth, the moon and other planetary bodies are evidence of these occurrences." -------------------------------------------------- Follow BI Video on Twitter: http://bit.ly/1oS68Zs Follow BI on Facebook: http://bit.ly/1W9Lk0n Read more: http://www.businessinsider.com/ -------------------------------------------------- Business Insider is the fastest growing business news site in the US.

A number of people who've seen NASA's annual lunar phase and libration videos have asked what the other side of the Moon looks like, the side that can't be seen from the Earth. This video answers that question. The imagery was created using Lunar Reconnaissance Orbiter data.

On Jan. 4, NASA announced the selection of two missions to explore previously unexplored asteroids. The first mission, called Lucy, will study asteroids, known as Trojan asteroids, trapped by Jupiter’s gravity. The Psyche mission will explore a very large and rare object in the solar system’s asteroid belt that’s made of metal, and scientists believe might be the exposed core of a planet that lost its rocky outer layers from a series of violent collisions. Lucy is targeted for launch in 2021 and Psyche in 2023. Both missions have the potential to open new windows on one of the earliest eras in the history of our solar system – a time less than 10 million years after the birth of our sun.

Largest asteroid impacts to have hit Earth What are the largest asteroid impacts to have struck Earth that we know of? Since Earth’s formation some 4.6 billion years ago, Earth was impacted many time by asteroids of various size, Thea Mars sized planet impacted primordial Earth early on, the impact almost destroyed the Earth and gave us our Moon. . During the late bombardment period it is estimated Earth was struck by at least six massive impacts, smaller planetary bodies’ some even the size of Enceladus, the moon of Saturn. The impacts were so dramatic that any life on Earth that might have evolved up to that point would have been wiped out instantly, however evidence of such impacts all but gone due to Earth’s active geology and plate tectonics. Finding a large asteroid impacts today isn’t easy, however massive impacts leave telltale signs. 545 million years ago Earth was hit by some really massive objects. Cambrian Impact Structure is believed to be a massive 600km impact crater created by an asteroid approximately 37x30 km. The object of such size impacting Earth would have created widespread devastation on a planetary scale. For impact scale Chicxulub impact was a lot smaller at approximately 10x9km. Chicxulub impact although very large and devastating on a continental scale, was not sole reason why dinosaurs went extinct, it was a nail to the coffin, but extinction process stared a lot earlier due to massive volcanic activity that was responsible for earlier extinction events some 250 million years ago.
