Dragon Spacecraft Qualification Unit
The Dragon Spacecraft Qualification Unit was a boilerplate version of the Dragon spacecraft manufactured by SpaceX. After using it for ground tests to rate Dragon's shape and mass in various tests, SpaceX launched it into low Earth orbit on the maiden flight of the Falcon 9 rocket, on June 4, 2010. SpaceX used the launch to evaluate the aerodynamic conditions on the spacecraft and performance of the carrier rocket in a real-world launch scenario, ahead of Dragon flights for NASA under the Commercial Orbital Transportation Services program. The spacecraft orbited the Earth over 300 times before decaying from orbit and reentering the atmosphere on 27 June. Delays In September 2009, the launch was slated to occur no earlier than November 29, 2009, however the launch was subsequently postponed ten more times, to launch dates in February, March, April, May, and June 2010, for multiple reasons including finding an open launch date, approvals, and retesting. The launch date was eventu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Boilerplate (spaceflight)
A boilerplate spacecraft, also known as a mass simulator, is a nonfunctional craft or payload that is used to test various configurations and basic size, load, and handling characteristics of rocket launch vehicles. It is far less expensive to build multiple, full-scale, non-functional boilerplate spacecraft than it is to develop the full system (design, test, redesign, and launch). In this way, boilerplate spacecraft allow components and aspects of cutting-edge aerospace projects to be tested while detailed contracts for the final project are being negotiated. These tests may be used to develop procedures for mating a spacecraft to its launch vehicle, emergency access and egress, maintenance support activities, and various transportation processes. Boilerplate spacecraft are most commonly used to test crewed spacecraft; for example, in the early 1960s, NASA performed many tests using boilerplate Apollo spacecraft atop Saturn I rockets, and Mercury spacecraft atop Atlas ...

Space
Space is a three-dimensional continuum containing positions and directions. In classical physics, physical space is often conceived in three linear dimensions. Modern physicists usually consider it, with time, to be part of a boundless four-dimensional continuum known as '' spacetime''. The concept of space is considered to be of fundamental importance to an understanding of the physical universe. However, disagreement continues between philosophers over whether it is itself an entity, a relationship between entities, or part of a conceptual framework. In the 19th and 20th centuries mathematicians began to examine geometries that are non-Euclidean, in which space is conceived as '' curved'', rather than '' flat'', as in the Euclidean space. According to Albert Einstein's theory of general relativity, space around gravitational fields deviates from Euclidean space. Experimental tests of general relativity have confirmed that non-Euclidean geometries provide a bet ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

2009 Norwegian Spiral Anomaly
The Norwegian spiral anomaly of 2009 (, "the spiral-form light pattern", ''det spiralformede lysfenomenet'', "the spiral-form light phenomenon") was a light phenomenon that appeared in the night sky over Norway in the morning of 9 December 2009. It was visible from, and photographed from, northern Norway and Sweden. The spiral consisted of a blue beam of light with a greyish spiral emanating from one end of it. The light could be seen in all of Trøndelag to the south (the two red counties on the map to the right) and all across the three northern counties which compose Northern Norway, as well as from Northern Sweden and it lasted for 10 minutes. According to sources, it looked like a blue light coming from behind a mountain, stopping in mid-air, and starting to spiral outwards. A similar, though less spectacular event had also occurred in Norway the month before. Both events had visual features of failed flights of Russian RSM-56 Bulava SLBMs, and the Russian Defence Ministry sa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
RSM-56 Bulava
The RSM-56 Bulava (, " mace", NATO reporting names SS-N-30 / SS-NX-32, GRAU index 3M30, 3K30) is a submarine-launched ballistic missile (SLBM) developed for the Russian Navy and deployed in 2019 on the new of ballistic missile nuclear submarines. It is intended to serve as a crucial component of Russia's nuclear triad. The weapon takes its name from '' bulava'', a Russian word for mace.
