manned Mission to Mars discussion

[SilentP]

Sorry to double post, but I didn't think this question would warrant a thread on it's own.

For any eventual terraforming efforts that may be made to make Mars more habitable, what kind of resource drain of Earth would we be talking about in terms of 'seeding' Mars (though this may be a general question for any planet)? Would Mars have enough raw materials for Terran life to be able to convert the planet to be liveable? Hopefully these questions make sense, or at least the spirit of them.

the European Space Agency has partnered with the Russian Institute for Biomedical Problems in Moscow to arrange a 105-day simulated mission to Mars. The experiment took place in a multi-floored facility in Moscow that includes a mock spacecraft, a descent vehicle, and a simulation of the Martian surface.

A group of volunteers that spent 105 days locked up in a mock spaceship simulating a trip to Mars is finishing up their final tests this week. The programme, which was used to test the psychological and physiological effects of isolation, will pave the way for a longer 520-day mission that will take place in the first half of 2010.

Hey at least they are testing this. NASA hasn't quite got there.

Basically humans are too stupid/the universe sucks ass too much for ftl to happen. Therefore a manned mission to mars, while looking cool, is a waste of time and effort. Until humans get smarter its really just mickey mouse.

This is the Science and Technology subforum.
Discuss the topic specifically.
john titor if you have nothing to add to the topic then please do not respond. This is a topic about a planned mission.

NASA already trains underwater at

This past Monday marked the kickoff of its 14th mission, sending six aquanauts down to the underwater Aquarius lab:

During their two weeks in the laboratory, the aquanauts will go on simulated spacewalks, operate a crane and perform other tasks of the sort astronauts would face in setting up a habitat on another planet. "The primary objectives are based on engineering and testing and operations design for planetary exploration," said William Todd, the project manager for the Neemo 14 mission.

And now the 520-day project begins for 6 astronauts.

Six would-be cosmonauts have entered a sealed facility where they will spend 18 months with no windows and only e-mail contact with the outside world.

"They will have to cope with limited consumables, for example," said Dr Martin Zell from the European Space Agency, a key partner in the project.
"That means everything will be onboard at the start. There will be no re-load, re-supply whatsoever. It will be like a real mission."

About half-way through the mission, three of the crew will have to "land" on this "surface" and walk about on it while dressed in heavy space suits.

The craft is based at Moscow's Institute of Biomedical Problems and comprises a series of interconnected steel canisters. The total interior volume is about 550 cubic metres.

semi-related...There is now a network TV fictional series in development about a manned mission to Mars.

let's see what happens in 2011 if it gets greenlit to series.

The US space agency has confirmed that it is carrying out feasibility studies to asses 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".

Speaking at a conference in San Francisco, Pete Worden, Director of Nasa's Ames Research Centre, recently said his division has received £1 funding to start work on the project. The research team has also received an additional $100,000 grant from Nasa, he said.

The astronauts would be sent supplies from Earth on a regular basis but they would have to become self-sufficient as soon as possible.

Worden believes that the first targets we should be aiming for if we manage to construct such a spacecraft should be Phobos and Deimos, the moons of Mars, rather than the Red Planet itself.

Internet rumor? No. Multiple sources.

NASA Ames’ Worden reveals DARPA-funded ‘Hundred Year Starship’ program
October 18, 2010


A new Journal of Cosmology article lays out the details:

The first colonists to Mars wouldn't go in "cold." Robotic probes sent on ahead would establish necessities such as an energy source (such as a small nuclear reactor augmented by solar panels), enough food for two years, the basics for creating home-grown agriculture, one or more rover vehicles and a tool-kit for carrying out essential engineering and maintenance work. In addition, the scientific equipment needed for the colonists to do important research work should be part of the preceding unmanned mission. All this equipment could easily be put into place using current technology before the astronauts set out.

Two researchers suggest four volunteer astronauts could undertake the first mission to permanently colonize Mars.

I can see the logic in sending a mission to Phobos as a stepping stone. It's got a lower gravitational field strength than Mars, so the required delta-V would be a lot lower. Also, if it's as pourous as it's been theorised, it perhaps wouldn't be out of the question to expand the base underground, since there's a chance it won't take much effort to remove the material (which in itself could be repurposed for manufacturing) to go underground, and the base can benefit from additional 'shielding' from radiation by living subsurface.

A great 41 page PDF file from a 2009 plan Austere Human Missions to Mars from NASA with 6-person crew:
http://trs-new.jpl.nasa.gov/dspace/b.../1/09-3642.pdf
pages 7-9 have some good diagrams of size of ships and how it would get there (manned, unmanned)

With a lot of diagrams its pretty easy to view.

I decided to put this in this thread rather than making a private funding manned Mars mission thread.
a permanent Mars colony privately funded.

Dutch company Mars-One says it's won enough sponsorship money to create a reality TV show which it hopes will in turn fund a manned trip to Mars.

The company hopes to use robots to build a habitable outpost between 2016 and 2020, and to land the first humans three years later.

It plans to start selecting a 40-strong potential crew next year, and televise the whole procedure. They'll need to be rather more committed than your average Big Brother participant: there are no plans to bring the settlers back.

Surely to be controversial since sending man on a one-way trip would be considered suicide and not in good spirit. This is sure to go against NASA and the US government. The Mars-One group will become more niche have a harder time finding enough funding.
Manned Mars mission wins initial funding

a global reality-TV media event, which will follow the mission from the selection of astronauts through their first years on the Red Planet.

Sort of like The Truman Show? At least this has an interest like the Olympics in many countries. It could be our first Truman Show style reality-TV type documentary series. As they say in the U.K. Factual documentary.

The first four astronauts will set foot on Mars in 2023, and more will arrive every two years after that. There are no plans to return these pioneers to Earth.

Mars One estimates that it will cost about $6 billion to put the first four humans on the Red Planet. The company hopes the "Big Brother"-style reality show will pay most of these costs. The televised action is slated to begin in 2013, when Mars One begins the process of selecting its 40-person astronaut corps.

Since it will be 40 people though I guess it would be under the competition-based reality TV genre.

Here is the Mars One intro film (4 minutes) at Youtube:

The whole reality show of the selection to 40 astronauts and their training could run for years including athlete endurance-style training, military-type bootcamp physical training, simulating desertlike conditions out in Utah. It is similar to the idea I had in this thread:
idea for science docu-reality TV series
It would be documented anyway but sure why not make it a series and international TV market coverage?

[sojourner]

I don't think the Mars One people are too well grounded in reality. Setting the technical hurdles aside, No reality show has made close to the money they would need to cover costs. Hell, I don't think the most popular sports in the world make that money on a per season basis off broadcasts.

[Dukhat]

This is the silliest idea I've ever heard in my life. A one-way Mars mission funded by reality-television dollars?

Now, if they instead went to a much closer place (i.e. the Moon), and DID have some means of returning to Earth if funding ran out, then it might be more feasible.

you need to bring everything with you to Mars including the return trip. The return trip is already bought and paid for when it gets there. Sending people on a one way trip to Mars is basically creating a hostage situation, the hostages are the people sent, and unless the public funds a resupply mission, they die!

This is really the place to have a discussion on nuclear power concepts. Right now the controversy on responsible missions to Mars means limiting transit times and thus rad-dosing of astronauts--ironically nukes mean less radiation exposure for astronauts.

There is a big arguement between nuclear thermal (NERVA type systems favored by Stan Borowski) and nuclear electric systems like Chang Diaz's
http://www.thespacereview.com/article/1896/1

That is fission end of things.

This technology can therefore be dual use--for smaller computers and Mars ships.

The way we go to Mars now is that we only use the LV to punt a wide warhead and let Mars run into it. That is the payload-centric course by folks who don't respect rocket-centric MSFC types who worry about how a spacecraft can slow itself down do the descent stage doesn't have to slam into Mars as hard.

Stan Borowkski's Nuclear Thermal seems most do-able in that we tested NERVA systems way back when when rocket engineers opinions counted for more than they do now.

The best approach--as per Stan Borowski

A nuclear rocket loaded with enough liquid hydrogen propellant would allow for one-way Mars transits as short as three months. That would also mean that the six-man crew would be exposed to much less space radiation enroute than during transits using conventional chemical propulsion.


To make the journey, the nuclear spacecraft’s three engines would be loaded with a total of 120 kgs of enriched Uranium-235, less than 1% of which would be fissioned during a round trip mission to Mars. That means the craft could be used on multiple missions providing it’s parked in earth orbit and resupplied with liquid hydrogen upon its return.


This is good for the folks who want depots.
