NASA is not sending plants to the ISS to see if they will grow... Do some research. Geesh. Growing plants in Space was originally done in the 1990s.
You think spending billions of dollars on a 2 week experiment is worth it when the exact same experiment can be done on Earth? Why does your experiment need to be done on Mars? Why not do it on Earth? You put your "micro-greenhouse" outside in a storm and it would be blown over in 5 minutes. These are things that can all be tested on Earth.You gave me answers for the heating and energy that were speculative and general. I wanted actual numbers such as milliAmp hours. And those are only surface questions there are many many more that you probably can't answer. How large of a surface area of solar panels will you need to keep the electronics going when under 30% maximal output? 20%? 10%? Running heating elements takes up a decent amount of energy how much energy are you going to need to store to run the heaters for 2 days? What temperatures is the battery going to need to be kept at without it going bad or reducing the output? I wasn't talking about dust storms. I was talking about dust settling on your solar panels, a problem all the rovers deal with. Do you know where their lander is going to land so you know more specifically the temperatures you will face? How quickly can your system respond to temperature fluctuations? Do you know during what Martian season your project will land?
There are basic questions Mars One can't and hasn't told you answers for I assume, and these are some of the first things needed to even plan a mission. Doesn't that set off an alarm? Much less more complicated questions such as how to create redundant hardware systems that are capable of handing certain g-forces and many other environmental and traveling issues.
Despite what people think NASA doesn't just put an arduino connected to LEDs on the ISS. At ~$10,000 / lb to send things to Space, they make sure it is going to work. It costs Millions to develop the electronics that can withstand the rigors of making it to the ISS and functioning as planned much less Mars.
Don't support Mars One. They are lying to you.

To be honest with you, we are very skeptical about the whole Mars One project. Very. I personally don't think their project will fly, and most of this is just a publicity stunt.
But we thought we can either do nothing and stare at the wall, or we can actually enter the competition and have a chance to send the first life from Earth to Mars. If we succeeded and managed to grow lettuce on Mars, it would be huge! Yes, it has a large chance of failure due Mars One's incompetence, but the chance of success is above 0%. So we think it is very much worth entering. We also need public support to win, so please consider voting for us in social media: www.lettuceonmars.com
There are a number of questions in this stream, let me answer them here:
Dakota:
Q: why lettuce? Isn't it completely devoid of almost all nutritional value?
It is. Its more of a proof of concept thing. We chose lettuce as it is well studied in closed systems, and so we have a lot of data on what parameters a lettuce growth chamber needs to have. Its also a pretty, leafy plant and its easy to explain why we need to grow it on Mars. There are a bunch of other reasons, if you are interested, I am happy to write a wall of text about it :)
Yuriy:
Q: Why pin all your hopes on Mars One?
We get funding at the university for building a greenhouse for Mars One. Otherwise we don't get funding. Publicity is a great selling point for any organization. We are doing a lot of research on lettuce at the University of Southampton, but this forum would never mention it otherwise.
Q: Are these common cultivars of lettuce or are these a special breed?
We will be using a lab breed, we have a number of candidates. We haven't pinned down our favourite yet, we will start testing them if we win the public support round. We have no funds beforehand.
Josiah:
Q: how their experiment will ever survive impact?
The Mars One lander for 2018 is basically a copy of the already successful Phoenix mission. That achieved a nice, soft landing on Mars and its the flagship project of Mars one, so even if their ludicrous ideas of establishing a colony don't work, this one is actually quite feasible.
Q: How well do you think your system will survive the cold temperatures, the warm temperatures and for how long?
During taxi to Mars, the lettuce seeds will be kept insulated, and their temperature will range between -40 to +35. This is something any plant growing in Canada is accustomed to, seeds certainly survive it without effort. After landing, we will use heaters powered by the solar cells of the lander, and heat our micro-greenhouse. We aim to provide acceptable conditions for the plants for 2 weeks. If we manage to keep them alive for 1 month, that would be a big success.
Q: How will your experiment obtain energy? solar power? What if the solar power is covered in dust, the plants or bacteria would die in a few hours?
If a dust storm occurs then we will lower temperature in the growth chamber, turn off the lighting, and can can switch off almost everything except the heaters. If we can maintain a temperature of 5C, lettuce will easily survive a few days even in complete darkness. The chance of a week-long dust storm is about 30-40%/year on Mars, so we are quite likely to have proper lighting for a 2 week mission.
Q: Think about it. If sending Lettuce or cyanobacteria to Mars or Earth's Moon would provide us will troves of new Scientific information for Space colonization don't you think NASA or the ESA would be doing it?
Funny you should ask that: ESA, NASA, ROSCOSMOS and CNSA have all sent edible plants to space for the sole reason of seeing if they grow or not. So yes, they would be doing it, they are doing it, all of them. Even as I write this, lettuce is growing on ISS. We have a lot of experiments to do on both the Moon and Mars, this is one of them, but since the agencies have limited resources, they are not sending a mission up every week.
Q: Please don't fall for what Mars One is saying. Even if they pick you, your project will never make it to Mars. Sorry. Want to contribute to Space Colonization develop new technologies that relate to sustainability of enclosed habitats.
This is exactly the kind of defeatist attitude space science faces every day. Yes, our project will most likely not make it to Mars. Does that mean we should just do nothing then? We have all the resources for this. The students involved can either go back to playing WoW, or build a greenhouse for Mars. Which one would you prefer?
