Nasa, Brookhaven, Long Island discussed on NASACast Audio
It's a simple, relatively simple surgery surgery, so it is a known space, radiation effect, but NASA call quantifies it as a acceptable risk because the the surgery for cataracts is fairly simple. It also manifest later on in life, and so it's not an in mission risk. So the thing with the sands risk which stands for spaceflight associated neuro ocular syndrome is that it's been only identified recently. There's still a lot of data to be collected from that. They're not sure if it's caused by microgravity if it's caused by fluid shifts, if it's caused by something else. Us elevated inter cranial pressure. So the there may or may not be some kind of interacting with radiation as well. We just don't know yet. Now, one thing about being a scientist and and you know you're working in the NASA space, radiation laboratory trying to get data points to understand what is happening. We're looking forward to going beyond low-earth orbit. Now, you know, we're talking about missions on the moon missions to Mars. Let's go to the moon for a second and assume we're, we're in the middle of a long duration. Stay on the moon. What scientifically from a radiation perspective and a biological perspective, are you looking forward to? So a lot of the samples, the data we get from astronauts and crew involves blood samples, and what we can gather from those samples is, are there any chromosome aberrations within the within those samples will kind of DNA damage is happening. So I think that is a one very useful tool. We call it by dissymmetry. So it's a biological measure of. Of the Dosimetry the radiation dose a you're gonna get. I think the bio Dosimetry from a long duration mission, long, duration mission at on the moon would be really useful. We don't have that data yet. Other things that would be interesting to look at our same thing in the blood samples, looking at biomarkers that are interest for all four of our wrists, so cancer CNS in cardiovascular disease. Other things that we could look at would be the cardiovascular morphology doing an echocardiogram on the heart or doing an MRI on the brain or even on the heart itself to look and see if there early markers sub clinical, but early markers that we can use to identify potential downstream effects and mitigate them earlier. Yes. So a lot of data that we can get really an to help us understand the environment. So can you tell us about some of the more recent studies that you've been doing for in terms of radiation may be in the NASA space? Radiation laboratory? Yes. We are planning an sorelle actually has three runs a year spring summer and fall in this fall eighteen see. We're planning to do the first test of her g. CR simulator. So we're going to irradiate animals and test out the scheme that we have to simulate the space, radiation GPS your field or going to irradiate them with six days a week. Rena Radi them with the schema, these five ion beams plus hydrogen and proton. And we're gonna see what happens to these animals overbearing lanes of time. And in that way, we hope to simulate a three year Mars mission and the end points that we might see in the human cohort. Okay. Yeah, so so it's coming up this fall where where. Is it again is it is an on the net? Yeah, the NASA space radiation laboratory is house at Brookhaven, National Laboratory. It's on Long Island, Long Island. Okay. So you're going up to. They have a lung to Brookhaven. National labs has a very large linear accelerator. And what they do is they pull off a little bit of the large beam in routed down to NASA space radiation laboratory, and that's very simplified way of what's happening with all the physics of it. But in that way that we can then sort of piggyback off the large lyric celebrator it's not, you know, when you say, oh yeah, we have to simulate this galactic cosmic Ray this galactic cosmic background radiation. That's not an easy thing like it's not. It's not easy at all. And as I said, this is probably the only facility in the world that is capable of doing it today. Yeah, we were talking. We were talking about everyone always asks us, you know, where's your?.
