The concept of launching a satellite into space using a cannon was first conceived by Isaac Newton in 1678. Since then, various superguns have been built, including the infamous Big Bertha. In 2007, Ballistic Flight Group LLC was founded with the goal of building the first cannon capable of launching a projectile into orbit, which […]
Space launches are expensive, with typical costs of $5,000-$10,000 per pound of payload. Fuel is a significant cost, with 25-50 pounds of fuel required per pound of payload. Building larger rockets can reduce costs, but the most promising solutions involve fuelless or fuel-efficient launches. These include using an air-breathing engine or electromagnetic accelerator, or building […]

Launch costs for sending payloads to low earth orbit range from $10,000 to $25,000 per kilogram. Chemical rockets have kept costs high, but equatorial launches and private spaceflight have helped. New methods, such as a cannon or space elevator, could reduce costs significantly. Launch costs refer to the cost of sending a payload from earth […]
Sea Launch is a spacecraft launch service that uses a self-propelled ocean platform located in the equatorial Pacific as a launch pad. The project cost $583 million USD and is owned by a consortium of four companies. It has successfully launched 30 rockets with two failures. Equatorial launches have benefits such as increased safety and […]
Aircraft generate lift from air moving over the wings, and can pitch up or down with the angle of attack. Control surfaces, such as ailerons, elevators, and rudders, are used to control roll, tilt, and yaw. The horizontal stabilizer creates a pitching moment to force the nose down, and the center of gravity is important […]
