Spaceguns Spaceguns The Industrial Sounding System is a proposed system to propel inert payloads to a height of up to 100 kilometers, or rocket-assisted payloads to 250km, with the use of a cannon. This might be useful when trying to launch science experiments into the thermosphere without the use of a rocket. There are plans to develop the ISS further to develop the capability to launch satellites into orbit. ...more on Wikipedia about "Industrial Sounding System"
The light gas gun is a highly specialized gun designed to generate very high velocities. It is usually used to study high speed impact phenomena ( hypervelocity research), such as the formation of impact craters by meteorites or the erosion of materials by micrometeoroids. Some basic materials research relies on projectile impact to create high pressure: such systems are capable of forcing liquid hydrogen into a metallic state. ...more on Wikipedia about "Light gas gun"
Project Babylon was a project commissioned by the Iraqi president Saddam Hussein during the Iran-Iraq War to build a series of superguns, with Gerald Bull supplying the designs for the guns. Although the details are sketchy, it appears that there were four different devices in total included in the program. ...more on Wikipedia about "Project Babylon"
Project HARP, short for High Altitude Research Project, was a joint project of the United States Department of Defense and Canada's Department of National Defence created with the goal of studying ballistics of re-entry vehicles at low cost; whereas most such projects used expensive (and failure-prone) rockets, HARP used a very large gun to fire the models to high altitudes and speeds. Started in 1961, it was created largely due to lobbying from Gerald Bull, a controversial but highly successful ballistics engineer who went on to head the project. His ultimate goal was to fire a payload into space from a gun, and many have suggested that the ballistics study was offered up simply to gain funding. The project received just over 10 million dollars during its lifetime. ...more on Wikipedia about "Project HARP"
A space gun is a method of launching an object into outer space using a large gun, or cannon. Though it is the earliest envisioned method of space launch, a space gun has never been successfully used to launch an object into orbit or even just space. If successfully developed, a space gun would offer access to space at an unprecedented low cost. However, the large accelerations experienced by a ballistic projectile would likely mean that a space gun would be incapable of safely launching humans or delicate instruments, rather being restricted to freight or to highly ruggedized satellites. Items launched into orbit from the ground by a space gun would need to have a small on-board rocket engine to circularize their orbit after launch, otherwise they would follow a trajectory bringing them back into contact with the ground. ...more on Wikipedia about "Space gun"
