For a long time, I research, science news, mainly related to cheap travel to Mars and other worlds.
For many years, scientists have developed projects for trips to the planet Mars. It started with the scientist Wernher von Braun (1947 to 1950) to the present. They do not just want to land there. They plan eventually settle on the planet and its Phobos and Deimos and terraform those worlds. However, even reducing costs of projects, they could not make a cheap travel to Mars.
The Hohmann transfer orbit used in space travel makes it impossible to go to Mars without spending billions of dollars. Just as an example, a trip to Mars lasts around 26 months and depends on large rockets.
Over this period, the spacecraft will roaring across space until reach the destination. However, until the landing, imagine the thousands of gallons of special fuel (dollars) burned. For this reason, the governments disapprove the projects.
Hohmann transfer orbit
Orbital mechanics in, the Hohmann transfer orbit is an elliptical orbit used to transfer between two circular orbits of different radii in the same plane.
The orbital maneuver to perform the Hohmann transfer uses two impulses engine, one to move the spacecraft onto the transfer orbit and the second move off it. This maneuver was named after Walter Hohmann, the German scientist who published a description of it in his 1925 book Die Erreichbarkeit der Himmelskörper (The Accessibility of Celestial Bodies). Hohmann was influenced in part by the German science fiction author Lasswitz kurd and his 1897 book Two Planets.
Researchers at Princeton University, in the United States and the Polytechnic of Milan in Italy, found a smoother and safer way to reach the Martian orbit called ballistic capturing. This method makes it possible cheap travel to Mars.
Consists of launching the spacecraft to a point in Mars orbit where the planet will transition later. Make the launch at a very low-speed. Eventually, when Mars passes down through its orbit, it will attract the spacecraft with its force of gravity.
The new method could open borders for more robotic missions, future manned expeditions and even colonization efforts. The dream of humanity cheap travel to Mars and other worlds is real from now on. “It’s a big surprise,” said James Green, director of the Planetary Science Division at NASA, for the magazine Scientific American:
“It could be a very big step for us and really save resources and capacity, which is what we are always looking for”.
