Travel To Mars – Biggest Dream Of Mankind!
Posted under SCIENCE & TECHNOLOGY, Space on Dec 2, 2008
One of the biggest dreams for mankind is the ability to travel to Mars.
It can be seen as a stepping stone towards the stars and beyond. The first real obstacle in the space age (which started with the launching of Sputnik in 1957) was the Trip to the Moon.
Trip to the Moon:
However, in the year 1968, the first trip to the moon was made and in 1969, the first landing at the moon occurred.
It was a monumental event and it was a huge step for the mankind. Now the second biggest obstacle that must be overcome is the travel to mars. It is hoped that in the near future, travel to mars can become a reality.
Obstacles in the travel to mars:
The first obstacle in the travel to mars is getting the large amount of payload (survey equipment, food and water, canisters of air, medical supplies, recreational equipment, and scientific equipment for the long journey ahead) that are required into the orbit of the Earth.
However, it is possible using Titan like rockets to carry tons of payloads into a Higher Earth Orbit (HEO). Once HEO is achieved, the payload and the personnel must be ferried aboard an orbital docking station to prepare them for the long journey ahead. These orbital docking stations would be similar to the International Space Station that is orbiting our world now.
Once the payload and the personnel are aboard on the orbital docking station, then the second step would be to get them across an Interstellar Space Transport Vehicle. This vehicle should be designed in such a way to allow all the personnel to live somewhat comfortably on the long travel to Mars.
Probably the main propulsion system and the main power system will be powered by a nuclear reactor. This is unavoidable, as just a couple of fuel rods would have the ability to provide enough energy for the ship’s life support systems and it would allow the crew to use as much as energy as they need for their daily activities.
Of course, the travel to Mars should incorporate enough air, enough food, and enough medical supplies to incorporate until the ship returns back to Earth.
Once the ship reaches Mars, they would need to deploy a special Landing Vehicle, which can separate itself from the main spacecraft so that the astronauts can land on Mars easily. Actually landing on the Mars itself is much easier then the travel to Mars from earth.
The main problems in the travel to mars will be with the amount of food, water and air that is needed in such a long journey. However, with air purification systems it would be possible to change the carbon dioxide we exhale into pure oxygen by stripping the CO2 molecule of its oxygen atoms.
Once the mission in Mars is completed, the same ship would have to lift off from Mars to rendezvous with the main space craft. Thus the Interstellar Space Transport Vehicle would then vector back on to the Earth until it reaches the high Earth orbit and docks with the Orbital Docking Station to signal the end of the journey.
President George W. Bush has announced that it has been made a priority for NASA to Travel to Mars. Thus the necessary research continues and it is hoped before the year 2025, the first travel to Mars can take place.
