How Area 51 Hid Secret Aircraft

Have you ever thought of what they do in area 51? Much speculated theories about US stealth aircraft are now confirmed and widely known. The Americans were testing a prototype of the OXCART. Apparently the Americans had to think about various ways to hide their aircraft from people but they had a bigger problem they knew they were surrounded by Russian spy satellites so they played a game of cat and mouse. They knew exactly the schedule of Russian satellites and they tried to trick them by making aircraft models of cardboard and other common materials in order to trick the infrared satellites buy casting fake shadows. When they saw the satellite coming over the horizon they would always scoot the planes in the garage where they had fake models of airplanes, which made it very difficult to test because they would have to go and pull it out and in and so on. Later on they discovered that Russian had a drawing of their plane thanks to the infrared satellite. When they plane is tested in the hot dessert it would create cool silhouette which was still visibly by infrared satellites. Sometimes they put heaters next to the fake models of plane’s engines to look like the aircraft has just landed. Despite all the Russians effort they never figured out the secrets of the plane before it was made public in mid 1960’s. It could reach the speed of 2000 miles per hour and cross the American continent in 70 minutes. Even thought it was really high tech it was not good enough to spot Russians satellite when flying over soviet union so it got really soon its improved successor. 

Scientists track falling satellite expected to hit Earth this week

Have you ever wonder what would happen if a falling satellite was about to hit earth in a week? Well a satellite will hit the earth this Friday. Scientist predicted that the satellite will most probably in water or on an uninhabited place. Since water covers most of the planet it is most likely it will also fall into water. The Chances of someone being hit by it is 1 out of 32000, but the chances of you being hit are 6 times less than winning the lottery. Most of NASA’s six ton Satellite would disintegrate on entering the atmosphere but there are still some parts that could cause serious damage. They say that 26 hazardous parts will enter the atmosphere intact weighting about 500 kilograms and moving at the speed of 90 to 380kph. It doesn’t seem like lots of speed but depending on how much it weights it will crush anything. There was also another satellite from Germany was going 28000 miles per hour but it landed in water so there were no casualties. 30 parts of the satellite entered the atmosphere weight with combined mass of one and a half ton. The satellite was launched at 1991 and decommissioned at 2005. The agency will make further updates as when the object is coming closer. NASA said that if any part of the derby lands near someone that they return the object by contacting the local police. Although there might be some arguments of if it lands on private property some people might not want to return it.

Lasers could be used t odecet roadside bombs!

Have you ever wonder how are we suppose to know were a bomb is so we can save people, well with the new invention from a research team in Michigan State University. Road side bombs account for around 60 percents of soldiers deaths. Lasers which can be used for a simple presentation also can use the sensitivity to canvas and detect explosive devises. Dantus said "Having molecular structure sensitivity is critical for identifying explosives and avoiding unnecessary evacuation of buildings and closing roads due to false alarms,". They detect explosive devise by using chemicals sensors. If the targeted object has the chemicals need for a bomb they would know the bomb type and where it is. Their newest laser can detect quantities as small as a fraction of a billionth of a gram. Another way it sees this is the chemical structure with differs from other substances.
