Astrophysicists believe that the first people to Mars should be sent through Venus – it will reduce fuel consumption, cost and will be safer for astronauts.
A team of researchers at Johns Hopkins University has prepared a report for Acta Astronautica, which suggests using Venus as a trajectory for flying to Mars. “An annual mission through Venus could be a valuable alternative for long-distance space flights and the first human mission to Mars,” the document says.
There are two ways to get to Mars: the first is the flight of a spaceship between two planets when their orbits coincide. The disadvantage of this plan is that the astronauts will have to wait about a year and a half before returning to Earth. The second way is a “shot from a slingshot” past Venus, and the use of planetary gravity will facilitate the flight of the ship, which means resources, time and cost.
The orbits of Mars and the Earth coincide every 26 months, when using the passage past Venus, the window falls on every 19 months.
