Humans may not have landed on Mars (火星) just yet, but that isnt stopping a European company from devising a plan to send four people to the Red Planet within the next few years. (78)This project, called Mars One, aims to send a small group of people to Mars in 2022and eventually establish a permanent colony on the planet. "Everything we need to go to Mars exists," said Mars One co-founder Bas Lansdorp in March 2014. "We have the rockets to send people to Mars, the equipment to land on Mars, the robots to prepare the setdement for humans. For a one-way mission, all the technology exists. " Yet the four astronauts (宇航员) chosen for the trip will be stuck on Mars—forever. And despite Mars Ones thorough planning, there are a number of challenges that may prevent the mission from ever taking place. (79)The biggest road block could be the missions huge cost ($ 6 billion). However, Lansdorp is confident that Mars One will be able to fund the project by selling the broadcast rights for the mission and subsequent experiences living on the planet. Those broadcast rights will also play a part in helping to select the people who will be sent to. Lansdorp said the company will hold a selection process similar to a reality show. Lansdorp is expecting at least 1 million applications from people around the world. In addition to the cost, several other potential problems could inhibit (阻止) the mission to Mars. " Its even more challenging to send people there with life support, with food, with air, with all the other things like books, entertainment, means of communication and of providing for their own resources for a long stay on Mars," said Adam Baker—senior lecturer in space engineering at Kingston University in London. "The sheer size of the rockets youd need to do this would be absolutely colossal. "
According to Project Mars One, humans could send four people to Mars within the next ______years.
