The Impact Of Computers

The B Foundation is a private nonprofit foundation with headquarters in the United States, dedicated to protecting the Earth from asteroid strikes. As a non-governmental organization it has conducted two lines of related research to help detect NEOs that could one day The impact of computers on the the Earth, and find the technological means to divert their path to avoid such collisions.

The foundation's current goal is to design and build a privately financed asteroid-finding space telescopeSentinelto be launched in — On February 16,the project was halted due to lack of grant funding.

As of July 13,the project is offline according to its website. Asteroids that absorb solar radiation can be observed through the infrared band.

It was used to detect NEOs, in addition to performing its science goals. Deep Impact[ edit ] Research published in the March 26, issue of the journal Naturedescribes how scientists were able to identify an asteroid in space before it entered Earth's atmosphere, enabling computers to determine its area of origin in the Solar System as well as predict the arrival time and location on Earth of its shattered surviving parts.

The four-meter-diameter asteroid, called TC3was initially sighted by the automated Catalina Sky Survey telescope, on October 6, Computations correctly predicted that it would impact 19 hours after discovery and in the Nubian Desert of northern Sudan.

Additional observations revised this probability down to zero. The ellipses in the diagram at right show the likely asteroid position at closest Earth approach.

At first, with only a few asteroid observations, the error ellipse is very large and includes the Earth. Further observations shrink the error ellipse, but it still includes the Earth. This raises the predicted impact probability, since the Earth now covers a larger fraction of the error region.

Finally, yet more observations often radar observations, or discovery of a previous sighting of the same asteroid on archival images shrink the ellipse until the Earth is outside the error region, and the impact probability returns to near zero.

Strategies fall into two basic sets: Delay exploits the fact that both the Earth and the impactor are in orbit.

An impact occurs when both reach the same point in space at the same time, or more correctly when some point on Earth's surface intersects the impactor's orbit when the impactor arrives. Delaying, or advancing the impactor's arrival by times of this magnitude can, depending on the exact geometry of the impact, cause it to miss the Earth.

The direct methods, such as nuclear explosives, or kinetic impactors, rapidly intercept the bolide's path. Direct methods are preferred because they are generally less costly in time and money. Their effects may be immediate, thus saving precious time. These methods would work for short-notice, and long-notice threats, and are most effective against solid objects that can be directly pushed, but in the case of kinetic impactors, they are not very effective against large loosely aggregated rubble piles.

The indirect methods, such as gravity tractorsattaching rockets or mass drivers, are much slower and require traveling to the object, time to change course up to degrees to fly alongside it, and then take much more time to change the asteroid's path just enough so it will miss Earth.

Many NEOs are thought to be "flying rubble piles " only loosely held together by gravity, and a typical spacecraft sized kinetic-impactor deflection attempt might just break up the object or fragment it without sufficiently adjusting its course.

Tracking the thousands of buckshot -like fragments that could result from such an explosion would be a very daunting task, although fragmentation would be preferable to doing nothing and allowing the originally larger rubble body, which is analogous to a shot and wax slugto impact the Earth.

In Cielo simulations conducted in —, in which the rate and quantity of energy delivery were sufficiently high and matched to the size of the rubble pile, such as following a tailored nuclear explosion, results indicated that any asteroid fragments, created after the pulse of energy is delivered, would not pose a threat of re- coalescing including for those with the shape of asteroid Itokawa but instead would rapidly achieve escape velocity from their parent body which for Itokawa is about 0.

Nuclear pulse propulsionRobust Nuclear Earth Penetratorand Operation Fishbowl Initiating a nuclear explosive device aboveonor slightly beneaththe surface of a threatening celestial body is a potential deflection option, with the optimal detonation height dependent upon the composition and size of the object.

In the case of an inbound threat from a "rubble pile," the stand offor detonation height above the surface configuration, has been put forth as a means to prevent the potential fracturing of the rubble pile.

Providing this stand-off strategy was done far enough in advance, the force from a sufficient number of nuclear blasts would be enough to alter the object's trajectory to avoid an impact, according to computer simulations and experimental evidence from meteorites exposed to the thermal X-ray pulses of the Z-machine.

This would have used a number of modified Saturn V rockets sent on interception courses and the creation of a handful of nuclear explosive devices in the megaton energy range—coincidentally, the maximum yield of the Soviets' 27 metric-tonne mass, Tsar Bomba if a uranium tamper had been used—as each rocket vehicle's payload.

Other techniques involving the surface or subsurface use of nuclear explosives may be more efficient, but they run an increased risk of fracturing the target NEO.While consumers use computers to communicate and entertain, businesses are primarily interested in computer technology as it relates to completing projects and handling specific business activities.

From this practical standpoint, computers have had an important impact on nearly every level of business operation. Impact of Computers On Society The concept of a computing device was there since the 19th century but the actual device was not invented until the s.

The computers invented at that time served as a project to simplify scientific calculations and they fulfilled that task quite perfectly.
