The planet Mars is one of the brightest objects in our night sky, even visible to the naked eye and resembles a bright red star. About every two years, our planet and Mars is a maximum converging. Such an event in astronomy is called “confrontation”. At this point, Mars will be only fifty-five millions of miles from Earth. People capitalize on that by sending to the Red Planet during the confrontation spaceships. So how much to fly to Mars ?
The orbit of Mars and Earth
The complete journey from Earth to Mars takes between 150 to 300 days to allow for the speed run, the location of the planets and the length of the path, which must pass the spacecraft. In this case the dominant factor is only the amount of fuel. The more fuel, the faster it will take flight.
History of flights to Mars
The first ever space ship, committed trip Earth-Mars, was created by NASA’s Mariner 4. It was launched in late November 1964 and appeared on Mars July 14, 1965. Mariner 4 reached Mars in 228 days. Continue reading
Solar system – 8 planets and over 63 of the satellite, which are opened more often, several dozen comets and many asteroids. All cosmic bodies move in their precise directional trajectories around the Sun, which is 1000 times harder than any body in the solar system combined. The center of the solar system is the Sun – the star around which orbits the turning of the planet. They do not emit heat and not light, but only reflect the light of the Sun. In the solar system now officially recognized as the 8 planets. Briefly, in order of distance from the sun, we list them all. And now a few definitions.
A planet is a celestial body that must satisfy four conditions:
1. the body must revolve around the star (for example, around the Sun);
2. the body must have sufficient gravity to have a spherical or similar shape;
3. the body should not be near its orbit of other large bodies; Continue reading
One day in April Gagarin made his flight, and today we are on such a universal scale occasion will transcend time and space.
Time is not linear, reality is relative, and can simultaneously be in two different places. To prove it, in our current cultural ranking, we sort of go back in time to learn about the future. With undying love for “the Martian Chronicles” and warm memories of childhood on the theme of Kir Bulychev’s works we decided this time to make more distant and mysterious space journey, revealing along the way a couple of other unknown planets. So, the first point of our sci-Fi trip -1938 year.
