If you divide the cost of a mission's launch by its cargo weight, you get some staggering numbers. Payload specialist and Space station engineer Ravi Margasahayam told Business Insider that each pound of cargo used costs $10 000 to ship into Space. Prices have skyrocketed since Orbital Science's Cygnus spacecraft's cargo cost about $43 180 per pound, and SpaceX's new carriers about $27 000 per pound. Business Insider determine that a 16 - ounce bottle of water can cost anywhere between $9 100 to $43 180 to blast into Space today. Space is full of junk like rocket parts and dead satellites. These objects continue to orbit Earth at about 17 500 mph, 10 times as fast as speeding bullet. The Space Surveillance Network keeps track of how much debris is out there and who's responsible for it. Ssn is currently tracking 23 000 objects larger than a softball. Space junk is dangerous because one collision could trigger a chain reaction of objects hitting each other, resulting in thick clouds of debris that would make space travel extremely dangerous. This kind of disaster was the premise of the 2013 movie Gravity starring Sandra Bullock and George Clooney. The US is responsible for most space junk with 3 990 pieces of debris as of March 28 2018. Russia is responsible for 3 959 pieces of debris, followed by China with 3 893. Dr. Ryan Stone has a hard enough time surviving with a spacesuit in gravity. Without a spacesuit, it would take mere seconds to asphyxiate. Because there's no pressure in space, air expands. This means air inside your lungs will expand and tear through tissue. And in such an extreme environment, your body would use up all of the oxygen in your blood in about 15 seconds. Other gruesome consequences of unprotected space exposure would include loss of bowel control, boiling blood, exploding capillaries, and bloating. Astronauts may be in free fall, but Outer Space isn't free - for - all. There are special space laws governed by the United Nations Office for Outer Space Affairs to make sure that space doesn't become a war zone or nuclear test site. Among them: no one can put a weapon of mass destruction into orbit, space exploration must be limited to peaceful means, and any country that launches an object is responsible for the damage it cause. You might think that there should be no black space at all because stars are everywhere and should fill the sky with light. This phenomenon is known as the Olbers Paradox, name of German astronomer Heinrich Wilhelm Olbers who pose it in 1823: if the universe is infinite, static, and timeless, then everywhere you look should eventually hit a star. It turns out the universe is neither static nor timeless. Edwin Hubble discovered that the universe is expanding, and thermal radiation left over from the Big Bang put the universe at 13. 8 billion years old. We don't see stars in every direction because some stars haven't been around long enough for their light to reach the US.

Interesting Facts about Space

Space does not begin at a specific altitude above Earth, but Karman line at 100 km is a commonly used definition. The temperature in the void of Space is about 270. 45 C. Space is hard vacuum, meaning it is void containing very little matter. There is no sound in Space because molecules are too far apart to transmit sound. Space between galaxies is not completely empty but has an average of one atom per cubic meter. There are an estimated 100 - 400 billion stars in our galaxy, Milky Way. The universe is observed to be 13. 8 billion years old and has been expanding since its formation in the Big Bang. In the observable universe, there are an estimated 2 trillion galaxies. The International Space Station is the largest ever crew object in space. Spacecraft have visited all known planets in our solar system.

5. Venus has super-powerful winds

Venus is a hellish planet with a high - temperature, high - pressure environment on its surface. Ten of the Soviet Union's heavily shielded Venera spacecraft lasted only a few minutes on their surface when they landed there in the 1970s. But even above its surface, planet has a bizarre environment. Scientists have found that its upper winds flow 50 times faster than the planet's rotation. European Venus Express spacecraft track winds over long periods and detect periodic variations. It also found that hurricane - force winds appear to be getting stronger over time.

9. Mercury is still shrinking

In the 19th century, geologists hypothesized that some of Earth's most dramatic landforms emerged because the planet had shrivelled over time, like juicy grapes becoming raisin. As Earth contract, they think, ground buckles in on itself, producing towering mountains, steep cliffs, and deep ocean basins. Theory works only if they assume that Earth was covered in a homogenous shell of rocky crust, which, it turns out some years later, wasnt case. In the mid - 20th century, as theories about colliding plate tectonics took hold, raisin hypothesis was abandon. But it was still a good theory, and it happened to apply to another planet: MErcury. Mercury, tiny but mighty, smallest planet in the Solar System, is circumscribed to a scorched existence close to the Sun. Where Earth has tectonic plates, MErcury has a thin, single crust enveloping its molten - iron core. Mercury is also way more metal than rock; its liquid core comprises more than 60 percent of its volume, compared with our planets ' 15 percent. It is basically a big ball of metal surrounded by little bit of rock, says Nancy Chabot, planetary scientist who studies MErcury at Johns Hopkins University apply Physics Laboratory. Humanity got its first good look at MErcury in the 1970s, when Mariner 10, NASA spacecraft, embarked on a tour of the Solar systems innermost planets. The Mission revealed that MErcury produces a magnetic field, invisible bubble that protects the surface from the worst of Sun radiation. Magnetic fields are generated from within, by planets liquid - metal core, still hot from its creation several billion years ago. Mariners also photograph chains of cliffs and ridges, some as tall as Washington States Mount. Helens, stretching for hundreds of miles. Landforms, known as scarps, fascinated scientists. They set about explaining scarps origins, and quickly rule out several explanations. Mercury bear marks of volcanismlong channels carven into rock by flowing lavabut activity ceased a few billion years ago. It also exhibits signs of ancient Bombardment by objects of various sizes, but such onslaughts produce craters, not mountains. Scientists examine what they know about planet formation. Iron cores of all rocky planets in our Solar System, including Earth, are still cooling down from their fiery births 4. 5 billion years ago. As liquid iron turns solid, it contracts, creating space for the crust above to contract, too. The ground cracks and thrusts upward, redrawing the landscape. If the planet was covered in uniform crust, like a lid, effects of this contraction would remain visible. Scarps, scientists predict, must be the result of this phenomenon. With this hypothesis in hand, scientists use Mariner images to calculate the length and height of scarps. They use measurements to estimate how much MErcury has shrunken in its lifetime. But they couldnt be entirely sure of even their best estimates.
