MARS CREW VOYAGE

Humans mission to Mars

A human mission to Mars has been the subject of science fiction, engineering, and scientific proposals since the 19th century. The plans comprise proposals to land on Mars, eventually settling on and terraforming the planet, while utilizing its moons, Phobos and Deimos.

The exploration of Mars has been a goal of national space programs for decades. Preliminary work for missions that would involve human explorers has been undertaken since the 1950s, with planned missions typically being cited as taking place 10 to 30 years in the future when they are drafted. The list of manned Mars mission plans in the 20th century shows the various mission proposals that have been put forth by multiple organizations and space agencies in this field of space exploration. Nonetheless, a human mission to Mars has been criticized for minimizing the "harsh realities and bitter truths that underlie the dream".

In terms of the current U.S. space program, NASA's long-term program Orion has a projected pace of development such that, as of late 2014, human spaceflight to Mars is anticipated in about 2035. That mission will be preceded by shorter flights for the up to four-person capsule involved, with experiments taking place to better the technologies protecting Mars-bound astronauts from the radiation of deep space. In October 2015, NASA presented the next steps in the effort in more detail, as well as a related health hazards report.

NASA'S JOURNEY TO MARS

NASA is developing the capabilities needed to send humans to an asteroid by 2025 and Mars in the 2030s – goals outlined in the bipartisan NASA Authorization Act of 2010 and in the U.S. National Space Policy, also issued in 2010.

Mars is a rich destination for scientific discovery and robotic and human exploration as we expand our presence into the solar system. Its formation and evolution are comparable to Earth, helping us learn more about our own planet’s history and future. Mars had conditions suitable for life in its past. Future exploration could uncover evidence of life, answering one of the fundamental mysteries of the cosmos: Does life exist beyond Earth?

While robotic explorers have studied Mars for more than 40 years, NASA’s path for the human exploration of Mars begins in low-Earth orbit aboard the International Space Station. Astronauts on the orbiting laboratory are helping us prove many of the technologies and communications systems needed for human missions to deep space, including Mars. The space station also advances our understanding of how the body changes in space and how to protect astronaut health.

Our next step is deep space, where NASA will send a robotic mission to capture and redirect an asteroid to orbit the moon. Astronauts aboard the Orion spacecraft will explore the asteroid in the 2020s, returning to Earth with samples. This experience in human spaceflight beyond low-Earth orbit will help NASA test new systems and capabilities, such as Solar Electric Propulsion, which we’ll need to send cargo as part of human missions to Mars. Beginning in FY 2018, NASA’s powerful Space Launch System rocket will enable these “proving ground” missions to test new capabilities. Human missions to Mars will rely on Orion and an evolved version of SLS that will be the most powerful launch vehicle ever flown.

A fleet of robotic spacecraft and rovers already are on and around Mars, dramatically increasing our knowledge about the Red Planet and paving the way for future human explorers. The Mars Science Laboratory Curiosity rover measured radiation on the way to Mars and is sending back radiation data from the surface. This data will help us plan how to protect the astronauts who will explore Mars. Future missions like the Mars 2020 rover, seeking signs of past life, also will demonstrate new technologies that could help astronauts survive on Mars.

Human Settlement on Mars

Mars One is a not for profit foundation with the goal of establishing a permanent human settlement on Mars. To prepare for this settlement the first unmanned mission is scheduled to depart in 2020. Crews will depart for their one-way journey to Mars starting in 2026; subsequent crews will depart every 26 months after the initial crew has left for Mars. Mars One is a global initiative aiming to make this everyone's mission to Mars, including yours. Join Mars One’s efforts to enable the next giant leap for mankind.

Landing

Permanent Settlement

The most complex, expensive, and risky part of a mission to Mars is the return trip. It requires developing bigger rockets that need a larger landing systems and launch capability on Mars. Permanent settlement is not easy but it is far less complex and requires much less infrastructure sent to Mars than return missions. Mars One has already started contracting established aerospace companies to work on the required systems. All systems require design, construction, and testing, but no scientific breakthroughs are required to send humans to Mars and to sustain life there.

Mission Design

A habitable settlement will await the first crew before they depart Earth. The hardware needed will be sent to Mars in the years ahead of the humans. This unmanned mission is currently scheduled for 2024.

The Journey to Mars

Astronaut Selection and Preparation

The global search has begun for the first humans to set foot on Mars and make it their home. In an extensive training period, candidates will learn the skills they will need on Mars and on their journey there. The combined skill set of each astronaut team member will cover a very wide range of disciplines.

In 1000 years, everyone on Earth will still remember who the first humans on Mars were. More than 200,000 men and women from around the world responded to the first call for astronauts.

My Opinion: I think this a very dangerous mission from NASA because as far as I know about mars this the most dangerous planet. But if they can succeed this the best way because of over population.  This is just another journey for us people who live on earth to discover and investigate life in another planet in the universe.
