100 year spaceship

Humanity seems to have stayed in their home Solar system

In Houston there was a scientific conference on the most ambitious project of the century.

“Transition to transformation”

Humanity seems to have stayed in their home Solar system. Of his burning desire to go to other stars, scientists said at a scientific conference, held in October in Houston (Texas, USA). Experts discussed the most grandiose project of the century – “Centennial spaceship” (“100-Year Starship”, or 100YSS ).

– Despite all the technological advances of humans, in the field of space exploration we’re on the level of cave people, – assured the leader of 100YSS Mae Jamison. All we did was hang a station in earth orbit, where just sometimes come to live people. And also sent a robot to Mars, which only publishes Pictures in Instagram and writes in Twitter. The main task of space exploration in the long term should be the creation of colonies, which can live people. Continue reading

Comet will reveal the secrets of the universe

NASA experts will soon do something that previously could only dream of and fantastic to shoot movies – get inside the comet. If all goes according to plan, tomorrow from the spaceport at Cape Canaveral launched the Deep Impact spacecraft, which will install a copper tube in the path of the comet Tempel 1. It is expected that celestial body will meet 372 kg heavy probe in a milestone for all Americans day – 4 July. After collision at a speed of 37 thousand km/h on the surface of the comet forms a crater the size of a ten-storey house.

The probe (it is a probe, not just RAM) immediately after the collision and the subsequent explosion will take samples of rocks that make up the nucleus of Tempel 1, and cameras mounted on the spacecraft, will take off the “dock” from beginning to end. All the information you plan to transmit it immediately to Deep Impact, located at a safe distance. “We will take the most powerful camera,” said astronomer Michael A’hearn, principal investigator of the project from the University of Michigan. For the clash will be the NASA orbital telescopes. In addition, the orbital meeting, which, according to forecasts, will remind fabulous fireworks will be visible using conventional ground-based telescopes. Continue reading

Solar system

It would seem that in the Universe can be arranged easier and more reliable than our Solar system . A crucial role is played by force of gravity; the motion of each planet around the Sun is subject to clear and unambiguous laws – the laws of Kepler; this movement is almost the same, common to all planets, except Pluto’s, the plane.

In reality things are not so simple. The fact is that on each of the planets of the Solar system is not only the power of solar gravity, but the force of attraction of the other planets. This pull causes disturbances in the movement of each of the planets of the Solar system. Several planet deviates from its normal path prescribed by the laws of Kepler, however, every time returning to it. When you consider that the mutual position of the planets of the Solar system changes all the time, it becomes obvious that the overall picture of their movement very difficult.

And so the question arises. If the perturbations of the planetary movements of the Solar system lead to irreparable disaster? Where is the guarantee that whenever getting off the rails invisible space, the planet will return to a “native” orbit? But if the deviation is too large? And if all this “inside buildup”, a kind of vibration, to cause Ravalomanana system? Continue reading
