LAUNCHING . Rocket-Space Complex N1-L3 being . ... As a result of high-frequency vibrations in the engine №2 gas generator, a pressure reducing connector behind a turbine broke off and leakage of components occurred that caused a fire in the aft compartment and violated the engine control system operation that commanded to shut down engines at 68.7s. Despite the accident, this launch has proved the validity of the dynamic profile, launch dynamics, LV control processes using the ...

In the early 1980s, our understanding of binary star evolution allowed us to construct a general evolutionary scenario which successfully explained the genesis of well-studied normal stars and offered potential explanation for new X-ray sources discovered in space experiments. ... At the present time it allows you to obtain evolutionary track of the close binary system with different parameters, which you determine yourself. ... To build your own track follow "Go to evolutionary track constructor". ...

Projectile Motion: In Aristotle's view, objects moved parallel to the Earth's surface until it was time (i.e. it was their destiny) to fall back to the earth . Aristotle believed that the "natural" state of massive objects was to seek the center of the Earth. When a stone is launched, an impetus is given to it to disturb it from its natural condition. ... Archimedes' catapults lobbed quarter-ton stones at the attacking Roman ships, quickly destroying the clumsy Roman siege engine. ...

The ion rocket is another means of providing thrust, more gradually but also more efficiently than a conventional rocket. ... As in the nuclear rocket, the energy which propels the xenon jet comes from a different source; here it is electrical energy from solar cells. The reason an ion rocket is much more efficient than ordinary rockets is the way its jet is produced. ... As with solar sails, solar ion engines are mainly practical in the inner solar system, where ample sunlight is available. ...

Globular Cluster NGC 2419 . ... The third is the remote globular star cluster NGC 2419 , at distance of nearly 300,000 light-years. NGC 2419 is sometimes called "the Intergalactic Wanderer", an appropriate title considering that the distance to the Milky Way's satellite galaxy, the Large Magellanic Cloud , is only about 160,000 light-years. ... NGC 2419 may really have an extragalactic origin as, for example, the remains of a small galaxy captured and disrupted by the Milky Way. ...

The ATNF is actively involved in looking for possible sites for a Radio-quiet Reserve in Western Australia. Two aspects of this project are currently being intensively studied: the degree of mineral prospectivity across the 50-km diameter areas of possible locations, and the planning of a comprehensive electromagnetic measurement program. The first of these studies is being carried out by the Western Australian Department of Minerals and Energy. ... SKA Site Engineer, ATNF . ...
