The dream of human beings about trip to mars has a long history, and at present, mankind is very close to implement such a project, it may sound like a Hollywood science fiction, but NASA is planning a new one-way mission in which astronauts will be sent to another world such as Mars to settle there for some time.
The US space agency is carrying out feasibility studies to assess whether astronauts could be sent permanently to the red planet, or its moons, to establish human colonies under the ambitious project called the “Hundred Years Starship”. Europe together with Russia is also planning its first manned mission to mars.
The astronauts would be sent supplies from Earth on a regular basis but they would have to become self-sufficient as soon as possible. The astronauts would have to embark on the mission knowing that they would never return to earth as the cost of returning would make the project prohibitively expensive. Depending on Mars’ position in its orbit around the sun, the distance between it and Earth varies from 34 million to 250 million miles. NASA’s last unmanned Mars mission, the Phoenix lander mission of 2007, took nine months to reach the planet; scientists say that nuclear-powered rockets could make the trip in four months. Recent research has shown that a one-way mission to Mars is technologically feasible and would cost less than a round-trip voyage.
A 400,000kg (880,000lb) Marship would be assembled in orbit using the Ares V cargo launch vehicle for a 900-day mission to the red planet, according to details that have emerged about NASA’s new Constellation programme’s manned Mars mission.The spacecraft would take a “minimal crew” to Mars in six to seven months, with the crew spending up to 550 days on the surface, according to the programme’s design reference architecture 5.0, currently in development. Each of the three to four Ares V rockets used to launch the Marship elements into low Earth orbit would need a 125,000kg payload capacity and use a 10m (32.7ft) fairing.
They are planning to send crews every 26 months; they will need up to 50,000kg of cargo. Scientists will use an aerodynamic and powered descent method also there is a 40 min communication delay between Earth and Mars so for that they will require autonomy or at least asynchronous operation with mission control. Scientists are planning to nationally launch it in February 2031; the first crew’s flight would be preceded by the cargo lander and surface habitat being sent in December 2028 and January 2029, respectively using two Ares V launches. A second mission’s habitat and lander will be launched by two Ares Vs in late 2030/early 2031 to reach Mars at the same time as the first crew. In the first quarter of 2033, the second mission’s crew will leave Earth to arrive at Mars by December, while the first crew leaves Mars in January 2033 after a 17-month stay, to reach Earth by September.
