Lunar Panel on Human and Bio Science

#NATLACADEMIES - Will need to break off here, have some domestic things I have to attend to. There IS one more presentation on the Lunar Effects on Agricultural Flora or #LEAF program coming up at 3:30 PM EDT vimeo.com/event/5234548

#NATLACADEMIES - Final Slide for concluding remarks

#NATLACADEMIES - Need to have measurement and forecasting systems that would be available to the crew. Also we could not come up with any experiments on the lunar surface for radiation protection foe the crew

#NATLACADEMIES - Could do the job with only dosimeters but it would be better with solar data however dosimeters are always the fallback, we do get info from the #GOES satellites If we had an observatory at L4 it would have a view of the Sun were most particle events originate (2nd placard )

#NATLACADEMIES - Need some better space weather forecast to increase the reliability of the models Also use the Acute Radiation Tool

#NATLACADEMIES - Big 3 questions , will be asked by the flight director and will use the ISEP Project to answer some of these questions ( placard 2 )

#NATLACADEMIES - Radiation Hardware that will be on board Artemis II and how Artemis 1 was used as a testbed for Artemis II

#NATLACADEMIES - can see in the first placard how Artemis II will flay though radiation fields, 2nd and third placards show how SRAG interacts and what support activities it provides

#NATLACADEMIES - Galactic rays change with the solar cycle when the sun is more active less particles make it to Earth, have modeling to dictate what particles can get through

#NATLACADEMIES - Solar Energetic Particles what are they?

#NATLACADEMIES - Space radiation data comes form both NASA and NOAA , Placard three shows the Van Allen Radiation Belt where Orion will be passing through

#NATLACADEMIES - Anywhere there is crew, there WILL be dosimeters there's a demo (HERA) that will be used on Artemis and another called RAD that is located in Node 2 on ISS Also Orion was the first ship built with radiation in mind.

#NATLACADEMIES - Types of modeling SRAG does

#NATLACADEMIES - Who makes SRAG up and what does it do? (cartoon shows a humorist view of what the organization is responsible for)

#NATLACADEMIES - Mission: To protect humans form impacts of space radiation

#NATLACADEMIES - Why do we manage the exposures? Galactic cosmic rays are even more damaging than terrestrial radiation sources. focused on human protection

#NATLACADEMIES - So why do we care about radiation List of In-Mission risks and there are long term risks of getting cancer any radiation exposure increases the risk

#NATLACADEMIES Next

#NATLACADEMIES - Summary

#NATLACADEMIES - The experiment on the lunar surface as outlined above would fit right in with the The Moon to Mars Architecture objectives, and the Decadal Survey.

#NATLACADEMIES - This is what a thick shield measurement may look like on there lunar surface, would take measurements as far away from the lander as possible. Need a nice flat area far away from other elements. hemispherical layers best re: the dose vs depth curve.

#NATLACADEMIES - Did have the thick shield project, GCR simulator was designed to study bio effects, need to understand what the secondary radiation field is inside the human. NSRL only goes to 11/2 GeV.

#NATLACADEMIES - Here's what is driving the knowledge gaps: Need measurement to understand mixed radiation, need additional ground based nuclear measurements, moon offers the deep space radiation at full intensity and the shielding mass is available Regolith very similar to aluminium

#NATLACADEMIES - Engineering and tech gaps, really have a goal of identifying materials for infusion looking for a reduction of 50% to get into the limits for a Mars mission. Have to improve our nuclear model by a factor of 2

#NATLACADEMIES - Today we can reduce exposure by 10%-15% - this is the current state of the art.

#NATLACADEMIES - If you have cheap mass to orbit you might be able to loft a thick shield but how thick does that shielding have to be? Slide shows Gap Structures 11 in all will focus on passive and environmental

#NATLACADEMIES - Challenges for the space radiation efforts. When you look at a Mars mission current mission duration estimates are at 870 day missions at minimum 1250 days Max. which would be twice the reasonable limit 1220 mSv. If you go during Solar Max, its better, perhaps go to fast transit

#NATLACADEMIES - ( some confusion on how together the slides to work with the ZOOM platform, standby)

#NATLACADEMIES - Next up

#NATLACADEMIES - In need of solutions - There are things that Generative AI can and cannot do. Mission Control can't fix everything and what kind of training is involved so we can bring down acceptable risk.
