What is The International Space Station?

 

ISS SPACE STATION

The International Space Station is a large spacecraft. It orbits around Earth. It is a home where astronauts live.
The space station is also a science lab. Many countries worked together to build it. They also work together to use it.
The space station is made of many pieces. The pieces were put together in space by astronauts. 
The ISS consists of pressurized modules, external trusses, solar arrays and other components. ISS components have been launched by Russian Proton and Soyuzrockets as well as American Space Shuttles.
The space station's orbit is about 220 miles above Earth. NASA and other space agencies uses the station to learn about living and working in space.
The first piece of the International Space Station was launched in 1998. A Russian rocket launched that piece. After that, more pieces were added. Two years later, the station was ready for people. The first crew arrived in October 2000. People have lived on the space station ever since. Over time more pieces have been added. NASA and its partners around the world finished the space station in 2011.
The purpose of the International Space Station is to provide an international laboratory to perform experiments within the space environment. For many of those experiments, the key parameter is prolonged weightlessness. 
ISS is the ninth space station to be inhabited by crews, following the Soviet and later Russian Salyut, Almaz, and Mir stations as well as Skylab from the US. The station has been continuously occupied for 15 years and 32 days since the arrival of Expedition-1 on 2 November 2000. This is the longest continuous human presence in space, having surpassed the previous record of 9 years and 357 days held by Mir. The station is serviced by a variety of visiting spacecraft: Soyuz, Progress, the Automated Transfer Vehicle, the H-II Transfer Vehicle, Dragon, and Cygnus. It has been visited by astronauts, cosmonauts and space tourists from 20 different nations.

Earth's shine seems to be fading due to global warming as the oceans heat up

  In recent years, the climate change crisis has escalated to unprecedented levels, resulting in unimaginable and life-changing consequences. An acclaimed new study contends that global warming is dimming our planet, literally! Global warming is causing the Earth's brightness to decrease, according to a new study. Now you're probably wondering, "how do you even measure something like that?" But researchers have their ways. Keeping track of the Earth's shine requires them to calculate the Earth's 'albedo', or reflectance. The albedo is calculated utilizing something called the 'earthshine'. The crescent moon is most noticeable immediately after sunset or before sunrise, when its dazzling crescent gives way to a dark disc with a faint glow. A crescent moon's unlit parts are known as earthshine because they are glowing from the light reflected from the Earth. The study revealed that earthshine data over the last three years indicates that our ...

What is Gun Cotton? How is it different from Black Gun Powder?

  Nitrocellulose (also known as cellulose nitrate, flash paper, flash cotton, guncotton, pyroxylin, and flash string, depending on form) is a highly flammable compound formed by nitrating cellulose through exposure to a mixture of nitric acid and sulfuric acid. One of its first major uses was as guncotton, a replacement for gunpowder as a propellant in firearms. Guncotton was actually developed as a “Smokeless Gun Powder”, Essentially, the main difference between Black Gun Powder and Smokeless Gun Powder is that you need almost zero incombustible components. The key problem with black powder was that it produced a cloud of smoke, not only from Un combusted carbon but also, unavoidably, from ash, the salts formed from whatever anion happened to latch on to the sodium or potassium cations present from the nitrates in black powders. Black powder ash contains a high proportion of potassium or sodium sulfates and carbonates, and because the inorganic saltpeter component was about 2/3 of...
