The Delta IV is a family of Delta Rockets designed by Boeing 's Integrated Defense Systems division and built in United Launch Alliance's The term boilerplate in Rocketry refers to a non-functional craft system or payload which is used to test various configurations and basic size load and handling characteristics In Spaceflight, a launch vehicle or carrier rocket is a Rocket used to carry a payload from the Earth's surface into Outer space. They are most commonly flown on the maiden flights of rockets, but have also been flown on return-to-flight missions after launch failures. Defunct satellites from cancelled programmes may be flown as DemoSats, for example the maiden flight of the Soyuz-2 rocket placed an obsolete Zenit-8 satellite onto a sub-orbital trajectory in order to test the rocket's performance. Soyuz 2 is the collective designation for the new generation versions of the Russian Soyuz Rocket. A sub-orbital spaceflight (or sub-orbital flight is a Spaceflight in which the Spacecraft reaches space, but its Trajectory intersects [1]
