How many fly to Mars?
Mars is one of the largest planets of the Universe, many people dream to go there. And how much to fly to Mars? And is it possible at all? Let's see.
Flight to mars
The most optimal time for a flight to Mars is the period of the Great Opposition: at this time the planets are most closely located to each other. However, there is a Great opposition once in 12-15 years, while the distance between the Earth and Mars is about 57 million km.
Scientists have identified two speeds (7.9 km / s and 11.2 km / s), which allow modern rocket and space technology to go into outer space. If we divide the distance between the planets during the Great Opposition by an increment of two speeds, that is, by 3.3 km / s (11.2 km / s - 7.9 km / s), we will get about 220 days, provided that the rocket will fly in a straight line. But since the spacecraft is flying in an arc, it turns out that time is spent more.
Scientists have calculated: for a flight to Mars and back at the most favorable time it may take about 500 days, while more time will be spent on the return tripsince the planets (Earth and Mars) will already begin to drift apart. Accordingly, the distance between them will increase.
