In every two years or so, red planet Mars and Earth reach their closest point, called “Opposition”, when Mars can be as close as 55,000,000 km from Earth. And every two years, space agencies take advantage of this orbital alignment to send spacecraft to the red planet. It usually takes 260 days or around 9 months (10-15 days more or less) to reach the red planet Mars from Earth (based on rocket’s velocity). Mars rover Curiosity which is now wandering on Mars took a few more days than 8 months to reach Mars. But still, 8 months is long time. In order to reduce travel time, the development of rocket’s engines is a must. Scientists have already engaged themselves to develop rocket’s engines. Researchers at University of Huntsville in Alabama are also trying to find out a way to diminish the travel time. The good news is they have found “Dilithium Crystals” which they think could cut the travel time to Mars down to as little as six weeks. In other words, it’ll take around six weeks to reach Mars from Earth. Get more unknown news inside.
