Editor's Notes
- A manned mission to Mars has been the subject of science fiction, engineering, and scientific proposals throughout the 20th century and into the 21st century. The plans comprise proposals not only to land on but in the end for settling on and terraforming Mars, while exploiting its moons Phobos and Deimos.
- After the Earth, Mars is the most habitable planet in our solar system due to several reasons:1. It’s soil contains water to extract2. It isn’t too cold or too hot3. There is enough sunlight to use solar panels4. Gravity on Mars is 38% that of our Earth's, which is believed by many to be sufficient for the human body to adapt to5. It has an atmosphere that offers protection from cosmic and the Sun's radiation6. The day/night rhythm is very similar to ours here on Earth: a Mars day is 24 hours, 39 minutes and 35 seconds
- There are several key challenges that a human mission to Mars must overcome:
- For Earth / Mars trips, this is every 26 Earth months (2 years and 2 months).During this time the crew will each have 20m3 of living space each, and won’t be able to shower.Image that, are you sure you are ready for the challenge?
- When would-be astronauts spent 520 days in a fake spaceship in a Russian car park to simulate a round trip to Mars, four of the six crew had trouble sleeping or developed depression during the mission.One crew member had such chronic sleep deprivation that he accounted for the majority of errors in concentration and alertness tests all crew undertook.
- A day on Mars lasts 40 minutes longer than it does on Earth. It doesn’t sound like a big difference, but when you’ve lived all your life with 24 hour days, you’ll notice.
- if you get ill, you’ll be (on average) 225 million miles away from Earth.(That’s what Earth looks like from Mars.)
- There’s always the chance that you’ll get infected with something from Mars.Then Earth wouldn’t even have you back if you tried.
- When the Curiosity rover took its 360 day trip to Mars, scientists measured the amount of radiation it was exposed to so they could work out how much radiation humans would be exposed to on the same trip.The total was 662 (plus or minus 108) millisieverts. That’s about two thirds the lifetime limit on radiation exposure of 1,000 millisieverts imposed by most space agencies on their astronauts.And because Mars doesn’t have a magnetic field protecting it like Earth does, you’d be exposed to more radiation every time you go out on to the surface.
- The negative effects of a prolonged low-gravity environment on human health, including eyesight loss.Gravity on Mars is just a third of what it is on Earth. Your bone and muscle would deteriorate and after a while your body wouldn’t be able to cope with normal Earth conditions anymore.It’s the same reason astronauts struggle for a while when they come back from six months in low Earth orbit.Others:The psychological effects of isolation from Earth and, by extension, the lack of community due to impossibility of real-time connections with Earth.The social effects of several humans living under crowded conditions for more than one Earth year, possibly two or three years, on the mission to Mars, and a comparable length of time on the return to Earth.
- Over the last century, a number of mission concepts for such an expedition have been proposed. Preliminary work for missions has been undertaken since the 1950s, with planned missions typically taking place 10 to 30 years in the future. 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.Eg.U.S. proposals (1950s and 1960s)Soviet mission proposals (1956 through 1970)
- Mars to Stay (2006); Since returning the astronauts from the surface of Mars is one of the most difficult parts of a Mars mission, the idea of a one-way trip to Mars has been proposed several times. Space activist Bruce Mackenzie, for example, proposed a one-way trip to Mars in a presentation "One Way to Mars - a Permanent Settlement on the First Mission" at the 1998 International Space Development Conference, arguing that since the mission could be done with less difficulty and expense if the astronauts were not required to return to Earth, the first mission to Mars should be a settlement, not a visit. Mars to Stay proposes that astronauts sent to Mars for the first time should stay there indefinitely, both to reduce mission cost and to ensure permanent settlement of Mars.
- The MarsDrive Organization has been working at a series of new human mission designs starting with Mars for Less. Their current design program under Director of Engineering Ron Cordes has discarded many of the Mars for Less elements and was reviewed as MarsDrive DRM 2.5 in June 2008. Some of their design philosophy is focused on using current or near term existing launch vehicle systems, permanent human settlement, conceptual EDL systems and enhanced surface ISRU. Their current design in 2012 is titled "Ready For Mars" and focuses on use of small Viking heritage landers to solve the Entry, Descent and Landing challenge. Their proposed methods of funding the mission are also an alternative to the current government funded plans with a private consortium approach being investigated.
- Mars One (2012)In 2012, a Dutch entrepreneur group revealed plans of a fund-raising campaign for a human Mars base to begin in 2023.One difference from other projects is that 'Mars One' is organized as a not-for-profit organization, strives to use worldwide suppliers, with no politics involved. It would be a "one-way" mission, i.e., there will be no return trip to Earth. Astronaut applications are invited from the public all over the world.In 2018, a telecom orbiter would be sent, a rover in 2020, and after that the base components and its settlers. The base would be powered by 3,000 square meters of solar panels. The SpaceX Heavy rocket would launch flight hardware. The first crew of 4 astronauts would land on Mars in 2025. Then, every two years, a new crew of 4 astronauts would arrive. Current plans specify that the entire mission is to be filmed and broadcast back to Earth as a media event, revenues from which would help fund the program.
