How crazy am I to think I actually know where that Malaysia Airlines plane is?
Theoretically, a space gun with a circular ring shaped track could utilize much lower accelerations because its effective track length is infinite with the object going around the ring numerous timesthough the centripetal acceleration could be enormous as the payload neared escape velocity, depending on the track size.
The German V-3 cannon program less well known than the V-2 rocket or V-1 flying bombduring the Second World War was an attempt to build something approaching a space gun. Based in the Pas-de-Calais area of France it was planned to be more devastating than the other Nazi 'Vengeance weapons'.
The cannon was capable of launching kg, 15 cm diameter shells over a distance of 88 km. Bull was assassinated before the project was completed.
Developed at Lawrence Livermore Laboratoryit is a light-gas gun and has been used to test fire objects at Mach 9. Ram accelerators have also been proposed as an alternative to light-gas guns.
Other proposals use electromagnetic techniques for accelerating the payload, such as coilguns and railguns.
Another famous example is the hydrogen accelerator cannon used by the Martians to launch their invasion in H. Wells ' book The War of the Worlds. Wells also used the concept in the climax of the movie Things to Come.
The device was featured in films as late assuch as Jules Verne's Rocket to the Moon. In the video game Ultima: Worlds of Adventure 2: Martian DreamsPercival Lowell builds a space gun to send a spacecraft to Mars. The video game Steel Empirea shoot 'em up with steampunk aesthetics, features a space gun in its seventh level that is used by the main villain General Styron to launch himself to the Moon.
In Hannu Rajaniemi 's novel The Fractal Princea space gun at the "Jannah-of-the-cannon", powered by a kiloton nuclear bombis used to launch a spaceship from Earth. The video game " SOMA ", features a space gun used to launch satellites.Also, it is very easy to transmit a carrier radio signal to a geostationary satellite and thus interfere with the legitimate uses of the satellite's transponder.
It is common for Earth stations to transmit at the wrong time or on the wrong frequency in commercial satellite space, and dual-illuminate the . A geostationary satellite travels from west to east over the equator.
It moves in the same direction and at the same rate Earth is spinning. From Earth, a geostationary satellite looks like it is standing still because it is always above the same location in relation to Earth.
Published: Mon, 5 Dec Weather prediction is a technique of forecasting weather patterns for a future time in a particular location or area. Historically, various techniques were used to predict the weather, based on observation of environmental and meteorological elements such as clouds, sunlight and animal behaviour.
