28 mar 2019 · To flyby or impact Venus varies from 3.45 to 3.6 km/s from LEO for the optimal time every 19 months. Mars varies from 3.55 to 3.9 km/s for the optimal time every 26 months. So on average, getting to Venus is a little less energy than getting Mars. But not by much. It could even be a tiny bit more in some years.
Refilling on-orbit enables the transport of up to 100 tons all the way to Mars. And if the tanker ship has high reuse capability, the primary cost is just that of the oxygen and methane, which is extremely low.
Mariner 2 (designated Mariner R-2) was launched on August 27, 1962, sending it on a 3½-month flight to Venus. The mission was a success, and Mariner 2 became the first spacecraft to have flown by another planet.
The fourth planet from the Sun, Mars is one of Earth's two closest planetary neighbors (Venus is the other). Mars is one of the easiest planets to spot in the night sky – it looks like a bright red point of light. Despite being inhospitable to humans, robotic explorers – like NASA's new Perseverance rover – are serving as pathfinders to ...

7 lip 2020 · There's a way to make crewed flights to Mars faster, cheaper, and higher-return: use Venus as a gravity assist. A group of scientists and engineers are proposing that a future Mars mission do...
