Curiosity cost $2.5 billion, and features lots of gizmos to look for the chemicals that support life as we know it. The lander set down where there are signs of water. So much good work done in anonymous silence is a puzzle. OK, so it took 253 days to reach Mars. NASA needs to do a better job of building a constituency for its work, and launching the imaginations of the next generation of rocket scientists.
Obviously, if you want to travel to Mars, it would be best to do so at the point of opposition, when Mars is âonly 35-63 million miles away. That is why rocket scientists time their unmanned missions to Mars to coincide with opposition windows every 26 months. The most recent opposition window was in May 2016 and the next one will be in 2018. If you dream of one day being an astronaut on the first manned flight to Mars, be prepared for a long trip. Scientists estimate a trip to Mars and back would take 400-450 days.
