14 sty 2015 · How much would it cost to go to Venus? An international collaboration of planetary scientists has just submitted a proposal for ESA to launch a mission to Venus in 2025. They’ve also helped us produce an infographic, inspired by our Rosetta cost breakdown, to put this proposed trip into context.
13 sty 2023 · Moving at a speed of 50,000-miles per hour, it would take 32-days to reach Venus, the closest planet, and 2,250-days to reach Neptune, the furthest planet.
28 mar 2019 · Venus transfer from Low Earth Orbit is 3.5 km/s, Mars transfer is 3.6. This will allow you to impact either body (on Venus you will need to make sure your vehicle is tough enough to actually impact, rather than dissolving in the atmosphere, but that's not really the point).
Between 1962 and late 1973, NASA's Jet Propulsion Laboratory (JPL) designed and built 10 robotic interplanetary probes named Mariner to explore the inner Solar System – visiting the planets Venus, Mars and Mercury for the first time, and returning to Venus and Mars for additional close observations.
Of the terrestrial planets Mercury, Venus, Earth, and Mars - Venus and Mars are immediate neighbours to Earth. Any quantity of missions have studied either. Venerean gravity is almost 90% of Earth's own. Venus is also closer to Sol than Earth - figuratively downhill that is.
Together with Rosetta and Mars Express, Venus Express makes up a family of missions in which costs are shared. By reusing the Mars Express design, you saved development costs, but how come the industrial contract for Venus Express was more expensive than for Mars Express? You cannot compare missions to different planets that way.
