Boeing 307 Stratoliner. The Boeing B-17 Flying Fortress is an American four-engined heavy bomber aircraft developed in the 1930s for the United States Army Air Corps (USAAC). A fast and high-flying bomber, the B-17 was used primarily in the European Theater of Operations and dropped more bombs than any other aircraft during World War II.
For example, a spaceship could travel to a star 32 light-years away, initially accelerating at a constant 1.03g (i.e. 10.1 m/s 2) for 1.32 years (ship time), then stopping its engines and coasting for the next 17.3 years (ship time) at a constant speed, then decelerating again for 1.32 ship-years, and coming to a stop at the destination. After ...
In physics, spacetime, also called the space-time continuum, is a mathematical model that fuses the three dimensions of space and the one dimension of time into a single four-dimensional continuum. Spacetime diagrams are useful in visualizing and understanding relativistic effects, such as how different observers perceive where and when events ...
The X-37 Orbital Test Vehicle is a reusable robotic spaceplane. It is an approximately 120-percent-scale derivative of the Boeing X-40, [ 6 ][ 22 ] measuring over 29 feet (8.8 m) in length, and features two angled tail fins. [ 26 ][ 40 ] The X-37 launches atop an Atlas V 501 [ 26 ][ 19 ] or a SpaceX Falcon 9 [ 41 ] or Falcon Heavy [ 42 ] rocket.
The B-17E (299O) was an extensive redesign of the previous B-17D. The most obvious change was the larger, completely new vertical stabilizer, originally developed for the Boeing 307 Stratoliner, and the addition of a tail gunner. Experience had shown the Flying Fortress was vulnerable to attack from behind.
t. e. In science fiction, hyperspace (also known as nulspace, subspace, overspace, jumpspace and similar terms) is a concept relating to higher dimensions as well as parallel universes and a faster-than-light (FTL) method of interstellar travel. In its original meaning, the term hyperspace was simply a synonym for higher-dimensional space.
On September 24, 2005, the spacecraft arrived at the Kennedy Space Center on board a C-17 Globemaster III for launch preparations. [82] The launch of New Horizons was originally scheduled for January 11, 2006, but was initially delayed until January 17, 2006, to allow for borescope inspections of the Atlas V 's kerosene tank.
Boeing Starliner. The Boeing Starliner (or CST-100) [ c ] is a spacecraft designed to transport crew to and from the International Space Station (ISS) and other low-Earth-orbit destinations. Developed by Boeing under NASA 's Commercial Crew Program (CCP), it consists of a reusable crew capsule and an expendable service module.
