Water rocket launch. A water rocket is a type of model rocket using water as its reaction mass. The water is forced out by a pressurized gas, typically compressed air. Like all rocket engines, it operates on the principle of Newton's third law of motion. Water rocket hobbyists typically use one or more plastic soft drink bottles as the rocket's ...

A laser-pushed lightsail is a thin reflective sail similar to a solar sail, in which the sail is being pushed by a laser, rather than the sun.The advantage of lightsail propulsion is that the vehicle does not carry either the energy source or the reaction mass for propulsion, and hence the limitations of the Tsiolkovsky rocket equation to achieving high velocities are avoided.
Although several projects take place in DARE, the group's two flagship projects are Stratos and Project Sparrow. Stratos includes the Stratos I rocket which was launched in 2009 and set the European altitude record for amateur rocketry at 12.5 km. [ 3 ] [ 4 ] The follow-up of this rocket was the Stratos II+, which was launched on 16 October ...
Lightcraft being propelled by laser. The Lightcraft is a space-or air-vehicle driven by beam-powered propulsion, the energy source powering the craft being external.It was conceptualized by aerospace engineering professor Leik Myrabo at Rensselaer Polytechnic Institute in 1976, [1] who developed the concept further with working prototypes, [2] funded in the 1980s by the Strategic Defense ...
The Reaction Research Society conducts complex amateur rocket projects, utilizing solid, liquid, and hybrid propellant technologies. The Tripoli Rocketry Association sanctions some amateur activities, which they call "research rocketry," provided certain safety guidelines are followed, and provided the motors are of relatively standard design.
JASON's 1977 study of laser propulsion, [29] authored by Freeman Dyson, succinctly articulates the promise of beam-powered launch: "Laser propulsion as an idea that may produce a revolution in space technology. A single laser facility on the ground can in theory launch single-stage vehicles into low or high earth orbit.
The film canister rocket uses a solid fuel mixed with a liquid fuel to create a gas that escapes out of the bottom. The gas is carbon dioxide (CO 2), the liquid is water (H 2 O), and the solid is an effervescent tablet. When the H 2 O is mixed with an effervescent tablet, it produces the gas CO 2. The reaction time depends on the surface area ...
