Discoverer: named after Edmund Halley opening date: 1758 (first predicted perihelion) Alternate designations: comet Halley (Halley), 1P Orbital characteristics: Age: 2449400.5 (17 February 1994) Aphelion: 35.32.e. Perihelion: 0.586.e. The semi-major axis: 17, 8 and.e. The eccentricity repulsed: 0, 967 Orbital period: 75, 3 and the Inclination of the orbit to the Ecliptic plane: 162, 3 degrees Last perihelion: 9 February 1986 Next perihelion: 28 July 2061 g the Period of revolution around the Solar system: from of 74.4 to 79.2 years. The average value of 76 years. Thanks to a successful “visits” in 1986 to comet Halley spacecraft “VEGA-1 and VEGA-2” (USSR) Giotto (ESA), “Suisei” and “Sakigake” (Japan) scientists got the first pictures of the core and comprehensive information:

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
Russia will fly into space on a nuclear engine. Go work on the creation of such a transport and energy module. This was stated by the head of Roscosmos Vladimir Popovkin in a holiday interview to “Rossiyskaya Gazeta”. Today, the country celebrates the Day of cosmonautics. Popovkin said that it is a compact machine with a capacity of one megawatt, the modules will be used in the composition of the inter-orbital tugs and even for interplanetary missions. Mass no analogues in the world.
Yuri Yurievich, what do you think? How realistic is it to create such a setup? How it would function?
Karash: to Create it, of course, real. As far as using it for interplanetary flights – it makes sense. With regard to inter-orbital tug – it is like flying on Boeing-474 from Moscow to Kaluga. I need to use nuclear installation does not see. But if you work its action somewhere within the Earth, then it certainly makes sense. In General, the use of nuclear thrust for interplanetary missions is the most promising.Suffice it to say that the company estimates MSNW (it’s an American company that, together with universitatsstra Washington now developing the nuclear rocket engine), with the use of this type propulsion system flight to Mars and back can be placed in the interval from 30 to 90 days.
