Mars One, a ticket to our dreams Mars One, a project aiming at sending humans to the remote Mars as well as establishing outer space colony, has aroused heated debate globally since it was launched. This one way mission signifies that the astronauts may never be able to come back to the Earth, which keeps many people wondering if it worthwhile to explore the unknown world in sacrifice of astronauts' lives. Some opponents argue that this one way trip is nothing more than a suicide mission. But what does it mean for the astronauts themselves? These brave men grasp the chance to pursue their dreams without second thought.Leaving everything behind, they prepare themselves for the rough conditions, tough missions and even deaths on the Mars, confirming that they will build up something for future generations. Human loss sounds terrible.

But as the saying goes, 'No pains, no gains', it is inevitable in the attempt to explore an unknown world. Besides, life away from the Earth may not be that unbearable and horrible as many of us imagine. Within astronauts' settlement are inflatable omponents which contain bedrooms, working areas, a living room and a plant production unit, where they will grow greenery.They will also be able to shower as normal, prepare fresh food (that they themselves grow and harvest) in the kitchen, wear regular clothes, and, in essence, lead typical day-to-day lives', cited from the official website of Mars One. When the astronauts leave the settlement, Mars suits specially made can enable them to do construction works or experiments freely.

In fact, moving to Mars makes astronauts accessible to further exciting adventure, nstead of sentencing them to a life in prison.Sufficient scientific proofs also back up my standpoint that Mars One can not be designed to be a round trip and robotic mission to dismiss the risk of possible human loss. According to Brian Enke, an analyst at the Southwest Research Institute in Boulder, a round trip will increase the uncertainty and complexity of the whole mission for it needs further consideration and preparation for the return trip, such as creating fuel for the return trip, launching an ascent vehicle for the return as well as orbital rendezvous.Enke also states that, compared to simplified human missions, robotic missions are not cost- inefficient in the slightest, due to robots' incapability to handle the unexpected emergencies as well to make significant decisions.

Personally thinking, this innovative and revolutionary project will bring enormous benefits on humans' development. As is known to all, humans' enthusiasm and desire to explore the outer space can date back to ancient times. And the Apollo Moon landing, humans' first voyage to the space, marked a historical moment of human history.After a series of uccessful aerospace explorations, we have been convinced that human beings will finally be capable to uncover all the mysteries of the space.

As the next giant leap for humankind, the Mars One project, if successful, can feedback valuable information about natural resources, environment and so on, enabling us to broaden our science knowledge and deepen our understanding about the unknown world. Moreover, the project will enhance the possibilities of migrating to Mars. Its various natural resources and vast land may contribute to the settlement of current populationAs is mentioned above, it is of genuine significance and urgency to launch the one way mission. Still, the Mars One project faces several tough issues, including both physical and psychological problems. Lack of water and oxygen, violent radiation and potential hazard of meteorite hits can all pose a great threat to the work and life of colonists on Mars.

Even if power, air, water, food, shelter, and building materials can be resolved, it will be hard for the colonists to overcome their own loneliness and despondence in the remote colony.The psychological problems lay the biggest bstacle to further development of the Mars One project. To sum up, we should confirm that Mars One project will mark a big step towards outer space exploration. Meanwhile, the potential dangers and difficulties underlying the project must be carefully measured and handled, for even a tiny mistake can lead to a total failure and kill all the colonists.

Kennedy once said in his household Rice Moon speech "We choose to go to the Moon, not because it is easy, but because it is hard".
