I read his obituary, sorry for your loss. That being said, I can hardly imagine anything more satisfying than walking around these labs and factories seeing exciting vanguard technology in the making for a living. And he clearly did his homework, with good and to the point questions. Top notch presentations, I've watched these clips several times. I guess you must have been told an interesting story or memory or two over the years. Take care.
understanding why they need all this information about the limits of the human body is similar to pulling a fish out of water. We're the fish in this instance, and space to us is like open air is to the fish. It has effects on the fish like space would have effects on us.
25:20 I would like to add this comment to what they are saying about extended missions on a lunar base or trips to Mars. Continued From Part 1 about Space Food posted on February 11th, 2021.The biggest challenge for a trip to Mars will be food. The reason is that they will not have the luxury of finding their own food like what earlier explorers did. Space food on a lunar base with the Artemis program and missions to Mars will play a huge role because not only will it have to be shelf stable for five years or more. The food will have to be grown on a lunar base or en route to or on the surface of Mars because their's not going to be resupply vehicles going to come and resupply the mission. The food that will be eaten on route to Mars will be no different from the ISS, but it will have to be supplemented by plants like tomatoes, cucumbers, lettuce and other plants. This will not only give astronauts a wider selection of food, but will provide a psychological boost because the astronauts will not only have the ability to process the food from one into quite a few different types of food, but the plants (like we saw in the film "The Martian") can remove the carbon dioxide from the atmosphere, recycle water and use the waste products as plant food. For a trip to Mars, inventory management is vital because there's no way that a resupply vehicle can come to your base on Mars and resupply your crew. The crew will have to keep track of what food they have, how much they have eaten and how much food is left and that is for the trip to and from Mars. On Mars astronauts will have to grow their own food and can use the martian soil to plant the food. For a trip to Mars radiation from both the sun and cosmic radiation will have to be taken into consideration. The reason is that radiation might change the composition or the taste of the food and might give it rancidity or give the food an off-taste and since there's no protection from radiation from the Martian atmosphere there must be a a way to protect the plants from radiation. Food of the future will have to not only have a shelf life of five years or more, but will have to be acceptable for the astronauts, but have enough nutrients to ensure that the astronauts can live and work on a lunar base and on Mars.

My first pair of glasses - 4th grade 1965 - were just like his! People thought you were more "intellectual" wearing black-rimmed glasses and a pocket protector. lol...
Actually it did. Because of Apollo 1, they pressurized the capsule to 14.7psi of air at launch. As it lifted off, they switched to 5psi of pure oxygen for the rest of the mission.
In regards to the space food seen on this video and what is served to astronauts now onboard the International Space Station I would like to add this comment that I posted on Retro Space Hd's video on Faith 7. Food in space has gone along way since the infamous toothpaste tubes and bite-sized cubes on the early flights. Now onboard the International Space Station, there is over 200 food and beverage items like shrimp cocktail, barbecue beef, spaghetti with meat sauce, coffee, grape drink. Food in microgravity, must pass strict shelf life standards and microbial count must be kept to a minimum. At the NASA Space Food Laboratory at JSC, Cologue, Germany and Star City, Russia astronauts and cosmonauts taste the food and decide and plan their own menu. In space there's a fluid shift that occurs that gives everyone the impression that they have a cold and it changes what food they like for example, if someone likes a certain food on earth and when they get up in space they don't like it or they don't like certain food on earth and when they get up in space they can't get enough of it. Since the Shuttle-Mir Program astronauts are paying more attention to their food selection. The reason is that on long duration flights of six months or longer food is more important for a astronaut or cosmonaut. Food pays a huge role not only in the physical well-being of an astronaut, but it is a huge psychological boost and improves their well-being because you can't just go to the nearest store in space for something, you either have it or you don't. There's several ways that food are packaged like some are your meats like steak, turkey, chicken are packaged in pouches like you would find in a MRE (Meals Ready To Eat). Rehydratables and beverage items, used to be packaged in hard plastic containers. Starting on STS-44 they are packaged in polyethylene and foil pouches because the packaging takes up less space and is easier to compact than the earlier packaging used in the early days of the shuttle. Salt and Pepper are in liquid form because the salt and pepper would get in a astronauts eyes and get into the electronics equipment and cause problems. Whenever the food quality standard is either below standard or unavailable the food is freeze-dried. Freeze-drying reduces the water count and ensures that quality is up to food safety standards for years. Fresh food is loaded in the launch vehicle within 24hrs of launch. Since STS-61B in November 1985, the tortilla has replaced bread as the jack off all trades for food. Food is delivered by Progress spacecraft, Japanese HTV, SpaceX Dragon 2, and Cygnus Spacecraft and is either docked or berthed at the International Space Station.

I would have liked to witness all the astronauts doing the tastings for their menus. I bet those were some fun times! I wonder if any stories of that exist? Interesting that they didn't mention "fiber" at all.
On short missions, it probably doesn't make much difference whether you get all essential nutrients or nothing at all for that matter. I guess the main objective is to not get stomach problems... But obviously these food scientists were thinking more long term, for the needs of staying in space for extended periods of time. Such as at the space station. But they probably overestimated the nutrient requirements for a person to stay alive. They should see how an average American is eating now in 2020...
The guy seems pretty frustrated on lack of human data.. "you can either take it with you or you don't have it". Testing on animal, which I find strange for on such a mission.. I'd be frustrated too..!
There's no human data for man's nutrition??? I busted out laughing at this guy! Here he is determining meals for NASA astronauts! He should be played by Tim Conway and this should be on the old Carol Burnet show. In fact I'd prefer it!
So, if the astronauts ran out of food while they were in outer space, they could always resort to cannibalism/animalism. They could draw straws to see who eats and who becomes the meal.
If world class food can be served on a nuclear sub, NASA can do the same in space, PROVIDED they're 1. not cheapskates 2. ready to dismiss all the food tech people trying to control the food and 3: can figure out how to put a decent freezer in space.
Back than the need for fat as a nutrient was known and considered as important. Very different from today where fat is extremely demonized as bad for health. This whole process to provide healthy food to go to war and than space turned into junk food highly processed industry with little nutritional value.
Was a neat trick how the food didn't explode when the lem was open to the vacuum of space when the actors opened the door on the moon also the car batteries that they used to do so much,amazing how those 1960s batteries were able to handle so much
Also amazing how you didn't attempt to think through the reasons as to how YOU could have misunderstood basic physics so thoroughly before posting this critical comment. Contrary to dumb theory, skepticism based on ignorance is not critical thinking...it's just ignorance.
Pure oxygen at *16 PSI* is what killed the Apollo 1 crew when the fire consumed it. 16 PSI was used to seal the capsule's inward-opening hatch against the 14.5 PSI of external atmosphere on Earth. This was changed with the redesign of the command module, as was the hatch itself.
@@HighestRank In a high pressure pure oxygen environment, however, a fire consumes all the available oxygen first. There's no oxygen left to breath for anyone in that moment. And that's how they were asphyxiated in about 22 seconds.
Damn, I know it's not in color, but if you could not see the food examples that they were clearly showing - for example, the reporter even ate a peanut product - then you need your eyes checked.
@@SweetBearCub that maybe true but i just don't believe men are leaving earth atmosphere to begin with because outerspace is a hoax nothing goes past the firmament aka vab
@@ejones6647 Bronze age notions of a firmament doesn't effect the reality of flying or going to the moon. Luckly, our understanding transcends 1,000 BC. by about 3,000 years. Recall, bronze age folk didn't have motors, jets, airplanes, cars and so many technologies that define modernity.
@@ejones6647 Why don't you ask Buzz Aldrin or Mike Collins? 50 years ago today (07/20/1969), Collins was in Lunar orbit while Aldrin and the late Neil Armstrong were pioneering the science of Moonwalking. :-)
