very light weight and durable alloys of titanium, aluminum and magnesium are commonly used.
In the near future we may use combinations of plastics and various hybrid materials such as metal-matrix composites that will greatly reduce the weight of a spacecraft, and greatly reduce launch costs. In fact, carbon fiber technology has already been used to replace many spacecraft components, except for the outer spacecraft bulkhead itself. Bulkheads are still made from titanium, aluminum or other conventional metals and alloys because of the tremendous thermal and pressure demands. The B-2 Stealth Bomber used carbon fiber materials in its wings, but the forces it would be required to take and the thermal loading are quite small compared to a spacecraft launched from the ground, or re-entering the atmosphere from space.
Fiber-reinforced materials such as carbon, aramid and glass composites have the highest strength and stiffness-to-weight ratios among engineering materials. For demanding applications such as spacecraft, aerospace and high-speed machinery, such properties make for a very efficient and high-performance system. Carbon fiber composites, for example, are five times stiffer than steel for the same weight allowing for much lighter structures for the same level of performance. In addition, carbon and aramid composites have close to zero coefficients of thermal expansion, making them essential in the design of ultra-precise optical benches and dimensionally stable antennas. Some carbon fibers have the highest thermal conductivities among all materials allowing them to be incorporated as heat dissipating elements in electronic and spacecraft applications.
Even carbon nanotubes and fibers are being developed with spacecraft and rocket technology in mind. So, we have a lot to look forward to in this exciting arena. Every pound saved is a major reduction in launch cost to the tune of $5000 per pound. This means that if you replace a pound of aluminum with a pound of some exotic new alloy, you have almost $5000 per pound in new allow cost to play with because aluminum counts for only one percent of the $5000!
Rockets are almost always used in space travel. It takes the thrust of the rocket to push the satellite or capsule to it's destination. 99% of the time, a rocket is used in space travel.
a space rocket is big and can fit many people but a bottle rocket is small and is used to send monkeys or satellites to space.
robot controlled rockets, sattalites, rovers, and many versions of manuel rockets.
In the past rockets have been used for many different things. In the 1200's, Chinese soldiers used them against their enemies. In 1930, Robert Goddard, was the first to set earthlings on a path into space. Hundreds of space crafts and satellites have been lifted into space by rockets. These satellites send information back to earth.
no, rockets carry equipment for people in space
space shuttles were made to be reusable, rockets were used only once
Yes, that is why they are used in space.
Some rockets are used for space travel and others are used for war. some other rockets are hand made like baking soda rockets. Rockets carry satellites and astronauts into space, missiles, distress beacons, even pyrotechnics (fireworks) for amusement.
They are used for going into space and as missiles.

Thousands if not millions. Not only are there space rockets, but also rockets used in research and war.
The intended benefits of rockets are that they are used to go in the space and they are also used to fight a war with other countries...

That refers to a rocket that goes into outer space - or that is used to drive something into outer space.
