Listen: John Batchelor, John Batchelor People, FOX discussed on John Batchelor
"Links about growing the crops in the end, the problem with excess oxygen that can impact can be very very toxic. And that there aren't really any tested system for removing excess oxygen in space. Let alone on Mars, although Mars, one group says that these are all systems that are already working either on earth or on the space station. How do you get rid of that set FOX agenda, and why is that a problem? Thank you for the question. So it is true that we need the oxygen removal system in. If we follow what Mars one Provo is actually proposing. So the technology of oxygen removal is used in on the ground in hospital. The Mars one. Muslim groups suggest. However, the technology that it's used on the ground is very different from what you are using space because of the environmental issues, and also, you know, gravity level is different and the radiation and so on so developing a technology for space rated requests, very high reliability, and and even different performance. In some cases. When the Muslim claims that they can do this mission using the existing technology. Winter we interpret that existing technology technologies that can be used for space right now if with that interpretation, the oxygen removal system is not a similar thing can be said about I saw you in today's. Well, because there have been no technology demonstration mission so far by you. So in terms of is how you and oxygen removal system and some other system that we identify in the paper, we need further technology development to actually make that happen. So the segment but most one made about the no. Thing technology can serve the purpose is not correct. I find that the most significant detail here because what you took was the Mars one mission and said, all right. What what can we say about the viability of this that the technology does not is not already extant all your paper identifies? What needs to be developed, especially what Cokie just referenced about the institute rece- resource utilization. What does that mean Olivia in situ resource utilization? And give an example of what we need to discover before we can do it. No, that's that's a great point. And the before I answer for ISU specifically, I just wanna make the point that, you know, we we are. We are our goal was not to to basically show that Mars one is impossible Mars. Call innovation can't be done with very supportive of it. I think we're all excited about those prospects. But we think it needs to be done based on on very sound models and sound science. And specifically I answer you technology is an area that NASA and other organizations have invested in. But but more needs to be done MIT was recently selected as the provider for the moxie experiment, which will find the March twenty twenty mission to to demonstrate essentially extracting gases from the from the Senate atmosphere of Mars, and that's quite challenging to do. And general is are you is a class of technologies that harvest's local resources weather from. Soil or the local atmosphere, and again, it's quite different from for the moon, and for Mars, but on Mars, we think that we can harvest, you know, the majority of the atmosphere on on on Mars is, of course, CO two, but you can you can take in that CO two and you can separate you can separate the oxygen? You can also extract potentially minerals from from the soil and each of these technologies requires thermodynamics a lot of chemistry and a cascades of chemical reactions that are more or less. Well, understood the real issues are scale ability and a lot of the experiments that have been done on Hawaii that were mentioned previously show that it can be done in principle, but after several batches filters get clogged and the productivity of an ICU system drops dramatically. Just a minute are festival when we come back. We'll continue with David Livingston, Dr space and the MIT campus team of an independent assessment of the technical feasability of Mars one mission plan in this century. I'm John Batchelor.
