The technique of composite ship construction (wooden planking over a wrought iron frame) emerged in the mid-19th century as the final stage in the evolution of fast commercial sailing ships. Construction of wrought iron hulled vessels had begun in the 1820s and was a mature technology by the time of the launch of the SS Great Britain in 1843.
Iron's advantages included being much cheaper than wood, not being subject to dry rot or woodworm, and its much greater structural strength. The practical limit on the length of a wooden-hulled ship is about 300 feet, after which hogging —the flexing of the hull as waves pass beneath it—becomes too great.
This is a list of fictional spacecraft, starships and exo-atmospheric vessels that have been identified by name in notable published works of fiction. The term "spacecraft" is mainly used to refer to spacecraft that are real or conceived using present technology.
As of August 2024 one more mission is planned to be launched on the Falcon 9 rocket from Cape Canaveral Space Launch Complex 40, and three from Wallops on an Antares 330. Cygnus is the only cargo freighter to launch on four different launch vehicles: the Antares 100 series, Atlas V, Antares 200 series and Falcon 9 Block 5. [26]
Lockheed Martin made a concept proposal to NASA in 2015 for a design called the Jupiter space tug, to be based on the designs of two earlier Lockheed Martin spacecraft—Mars Atmosphere and Volatile Evolution Mission and the Juno—as well as a robotic arm from MDA derived from technology used on Canadarm, the robotic arm technology previously ...
Progress M2 was a planned variant, which was a proposed design for the proposed Mir-2 space station, but was dropped due to financial issues. The M2 variant would have a larger service module for larger cargo or space station modules and would have been launched on a Zenit rocket as the spacecraft is bigger.
The SS Alpena (formerly the SS Leon Fraser) is a lake freighter. She was built in 1942 by the Great Lakes Engineering Works in Ecorse, Michigan, to carry iron ore. She was originally owned by the Pittsburgh Steamship Company, a subsidiary of United States Steel. After also hauling grain in addition to ore in the 1960s and 1970s, the ship was ...
After separating from the Dual Engine Centaur, the Starliner's own thrusters, mounted on its service module, boost the spacecraft into orbit to continue its journey to the International Space Station. The suborbital trajectory is unusual for a satellite launch, but it is similar to the technique used by the Space Shuttle and Space Launch System.
