Experts on the ground give them advice if they need to improve their diet.
Main Idea 3: Some people need dietary restrictions and de-restrictions to be able to live on space. Central Idea: Nutrition and high morale are crucial for exploration.

Main Idea 3: Some people need dietary restrictions and de-restrictions to be able to live on space. Central Idea: Nutrition and high morale are crucial for exploration.
Getting enough calories, vitamins and minerals is as important for astronauts as it is for people living on Earth. They have to eat at least 2000 calories per day.
Main Idea 2: Astronauts need enough nutrients, similarly to those on earth, despite the microgravity conditions.
Drinks range from coffee, tea and orange juice to fruit punches and lemonade.
Why not cubes and mimics of drinks with artificial flavoring and sweeteners? The dangers of liquid are immense in space.
Ovens are provided to warm foods to the proper temperature.
How to ovens work in space? Considering the zero-gravity conditions that the users need to endure.
It may be freeze-dried, low moisture, pre-cooked or dehydrated (with its water removed)
Main Idea 1: There are a variety of ways to get food and nutrients into people in space.
Space food may be canned or wrapped in aluminium foil.
Is there any other storage methods, and if so, why aluminum foil?
plus snacks that can be eaten at any time.
Which snacks are astronauts able to access?
Salt and pepper are available too, but only in a liquid form.
Why in liquid form? Shouldn't they be kept solid to prevent spills and damages to machine hardware?
more than 100 items. Astronauts choose their daily menus long before they fly into space.
So they attempt to get the astronaut's favorite meals to boost morale?
include frozen vegetables and desserts, refrigerated food, fruit and dairy products.
There aren't any dry variants of food, and seemingly are intended for storage in fridges or freezers on the ISS.
Today, space foods are similar to those eaten every day on Earth.
How did they accomplish this?
Eating in space has improved a lot since the days of cold paste in aluminium tubes and cube-shaped bites.
Did the old variants of food still provide the same amount of nutritional value as the modern variant?
Astronauts are far from the shops, so they have to rely on regular deliveries of food. Every few months an automated spacecraft, such as ESA’s Automated Transfer Vehicle or the Russian Progress, arrives loaded with fresh fruit, water and pre-packed meals.
Judging by the amount of times food is delivered to the ISS per month (aka once per month), do they also include forms of plantation in order to grow food, or do they just pack enough for a month?
Our bodies depend on Earth's atmosphere to survive. Not just for oxygen.
So they basically have a larger and much more important job than supplying oxygen, like forming a defensive layer for any debris, kind of?
Outer space has other hazards - freezing temperatures, lethal radiation. But here's the good news you won't live long enough to have to worry about them. Despite all the dangers, if youre rescued within 60 seconds, you'd probably survive.
So you die once you reach the 60 second limit? Huh, that's really terrifying because you're basically on a time limit to depend on your fellow crew members.
After a few minutes, if the lack of oxygen hasn't killed you, the damage from depressurization will.
I'm really glad that spacesuits exist, otherwise we would not be able to go to space at all.
Youll swell to about twice your normal size. Your body wont explode like you see in some movies, but you will be in a world of hurt.
Assuming that the vapor is from, well, heat and the swelling is from thermal expansion, wouldn't the suits be designed with some cooling mechanism/fan to keep your body from expanding too far, but as well as keeping it from exiting the suit's boundaries?
Now, you might be thinking - I can hold my breath for a minute! That might work underwater or under our atmosphere, but in outer space, there's no outside pressure.
The lack of shielding on your skin and the definite idea of dying from frostbite in space due to the lack of heating terrifies me.
The most serious danger is asphyxiation. After about fifteen seconds, your body has used up all the oxygen in your blood, and your brain loses consciousness.
From the lack of air within space, it's really dangerous to just, fly out into space without any regulative equipment nor any form of oxygen supply.
The atmosphere protects us from ultraviolet radiation.
The suns rays are really powerful, and they can also release solar flares, so the suits are designed to survive them, right?
It takes from about four minutes to almost as much as a half-hour for light to travel from Mars to Earth
I thought it took 11 minutes, welp, false information from my part.
Instead, the spacecraft must be able to receive commands from operators on Earth, then execute them on its own.
Huh, that's kind of surprising that they're going with that approach.
The Mars Helicopter is an autonomous spacecraft.
Considering the 11 minute delay between commands, is there some sort of A.I implemented to spot obstacles similarly to how the Boston Dynamic's robot dog can do so?
The car-size rover is equipped with a drill for collecting rock samples, and instruments for conducting chemical analyses and seeking potentially habitable environments.
Percy does share some similarities with Curiosity, though the fundamental point is it's infrastructure.
If all goes according to plan, the craft will make four more flights over the course of a 30-day test campaign, each progressively longer and more complex than the first.
That's really exciting to see the progression of.
If the Mars Helicopter fails, the overall Mars 2020 mission will not be harmed. But the potential upsides for NASA are thrilling. A successful mission could pave the way for the future of the rotorcraft.
Aviated mars colonies, perhaps?
The helicopter is equipped with solar cells. The cells will charge its lithium batteries and an internal heating mechanism to keep it warm through the Martian night.
They found a way to store solar energy into batteries? Suprising.
To make it fly at that low atmospheric density, we had to scrutinize everything, make it as light as possible while being as strong and as powerful as it can possibly be
As I previously mentioned, they need to buff up the wingspan and minimalize size at this point.
It took four years of testing and redesign to create a helicopter capable of operating on the Red Planet. Mars' atmosphere is very thin. Hovering just 10 feet above the surface is the equivalent of soaring 100,000 feet above Earth.
How so? I'd generally expect gravity to be lighter considering the planet is much smaller and therefore makes a smaller gravitational pull on things around it, but eh.
orbiters, landers and rovers to explore Earth's neighbor. NASA's next mission will be the first to send a tiny robotic helicopter to another planet.
Now that the first flight test has already happened, as well as the deployment of Perseverance, it kind of still fascinates me of how far we've come and how much research went into this idea.
Still, it is so distant that it would appear to Earthlings as a doughnut on the moon.
The perspective kind of reminds me of Carl Sagan's quote, which I quoted on a different annotations, because we're just one spec, and yet we've 'conquered' black holes and discovered pictures of them, this truly is fascinating on how far we've come.
Ozel helped coordinate the week of observations from the project's makeshift command center at the Massachusetts Institute of Technology. She recalled the surge of excitement as hundreds of astronomers around the world prepared for their first night of work.
Surprisingly this has about the same amount of people working on it as the German V-2 Rocket.
"If the scientific goal wasn't so attractive and so full of potential, and if we hadn't spent so much time working toward this goal, I think it probably would have fallen apart," Ozel said. "The science kept us together."
Connecting it back to 'The Smithsonian History of Space Exploration', Space Exploration is kind of an effort for the entirety of mankind, not just a singular person, but uniting over a single topic is really difficult, but science and it's ideals is just that fascinating in my opinion.
In 2016, scientists detected ripples in spacetime caused by black holes colliding. These ripples are called gravitational waves.
Black holes colliding lead to larger black holes, right? So could the sound also be produced by the fusion of two?
Karl Schwarzschild calculated that if an object is dense enough, it would create a bottomless pit in spacetime known as a "singularity." Anything within a certain radius of that pit — a region known as the "event horizon" — would be swallowed by its gravity. A black hole —another name for a singularity — consumes clouds of gas and stars that wander too close. Not even light can escape.
Karl Schwarzschild is a really cool mathematician/physician, he literally came up with a solution to Special Relativity right before he died.
The foundations for this discovery were laid more than 100 years ago, when Albert Einstein published the equations that defined modern gravitational physics. General relativity, first described in 1915, explained gravity as a force created when matter warps the geometry of space and time. In turn, curved space and time ("spacetime") tells matter how to move.
Considering the theory of relativity was built around space time being a fabric of sorts and every planet/interstellar object/celestial being had a weight, I think that an object with a 'infinite' amount of weight could be possibly theorized back in 1915.
Event Horizon Telescope (EHT), a network of eight radio telescopes that operate in tandem.
Not being a single telescope taking pictures is much more reasonable and meets my general idea, though if it were to be a cluster in orbit that would be much better considering the range would perhaps be farther.
It sits at the center of Messier 87, the largest known galaxy.
How large would Messier 87 be to qualify to be the largest discovered though?
Event Horizon Telescope collaboration
Objectively I'd expect hubble to take a picture of it considering it's range, but I'm unsure if it actually got decommissioned or not.
The results of the one-year mission will provide more insight into these changes over a longer period of time, and present a stepping stone for even longer missions.
One year? For the first mission? I was expecting 3 months of something atleast smaller than that.
NASA is using the space station to figure out what types of medical events happen in space over six months and what types of skills, procedures, equipment, and medication are needed, so you will have a good idea of what you’ll need to pack for Mars. You can produce Intravenous (IV) solution from purified space station cabin water, and then mix it with salt crystals to produce normal saline for medical administration.
Multiple skillsets really need to be aboard this mission, there's too many roles that need to be fulfilled, and I'm pretty sure the minimal amount of people that are going to be on mars is 5, and there are oh so many jobs that need to be done.
The space station sits just within Earth’s protective magnetic field, so while our astronauts are exposed to ten times higher the radiation than on Earth, it’s still much less than the radiation a mission to Mars will encounter, and of a different type. Shielding, monitoring, and operational procedures control the radiation risks to acceptable levels to keep you safe.
10 times more radiation is a stretch, so confinement kind of needs to be required for the astronauts to live, though that of it's own right is already another issue NASA is tackling.
NASA is using technology to monitor the air quality of the space station to ensure the atmosphere is safe to breathe and not contaminated with gases like formaldehyde, ammonia, and carbon monoxide.
That is a incredibly long list of gases, but the important thing about this is also the working conditions, perhaps. The suits need to be cleaned, rovers need to be cleaned and stayed within perimeter of the colony to prevent communication problems as well as loosing valuable pieces of technology from a measly dust storm.
All of these methods and technologies will help us prepare for longer, farther exploration missions.
I think maybe forms of entertainment would be available on mars, books, maybe handheld offline games, but books especially need to be on a mars mission, manuals are important for guidance when there's an 11 minute delay.
small, noisy environment, or the stress of prolonged isolation and confinement. Depression could occur. Fatigue is inevitable given that there will be times with heavy workload and shifting schedules.
Now that I think about it, mars is a really hazardous location to be in, filters need to be monitored, suits need to be cleaned to prevent infestation, etc. etc.
Expedition crews selected for a stay aboard the space station are carefully chosen, trained, and supported to make sure they can work effectively as a team for six months. Crews for a Mars mission will undergo even more scrutiny and preparation, since they will travel farther and longer than any previous human, being more isolated and confined than we can imagine.
I'm partially glad that they will openly adjust plans of separation and confinement because Mars is at least 30 times farther than the ISS and due to the lack of communication delay being about 11 minutes, it's partially necessary for every task to be fulfilled by the crew with no issues.
protection against these changes for a Mars mission can be developed. Functional task testing is in place to help detect and minimize the effects of space on your balance and performance.
Applying the gravity and general effects of mars to an artificial being works, but how would you apply that to a biological person? By applying a person through simulation tests online to see if they can withstand Martian dust storms?
Compression cuffs worn on your thighs will help keep the blood in your lower extremities to counteract those vision changes.
Wait, this also makes the vessels compressed which minimizes blood flow, so yeah, that's REALLY useful.
Bisphosphonates drugs have shown to be effective in preventing bone loss.
The medical standpoint of space exploration is particularly important in my standards, but there surprisingly is a drug for bone recovery as well?
how much urine you produce in space, which is essential to human research since it reveals key information about your health.
I've never known that, actually. I mean objectively your vitamins and minerals need to be extended and 'modified' for space travel, so technically it could be an actual valuable asset?
Scott’s data will help researchers determine whether the solutions they’ve been developing will be suitable for such long, onerous journeys.
I think the data would be INCREDIBLY valuable considering you just need to boost that by 3 times, though I think other symptoms would be in the equation of health risks due to the extended period.
Rest assured, when we take the next giant leap to Mars, we will be ready.
Huh, considering this was released in 2015, nobody didn't really know about Artemis.
otherwise you could compromise your health since nutrients are required for the function of every cell and system in your body.
Don't cells die upon the movement of a limb, so technically you need a LOT of cells/rapid production to move, right?
Medications react differently in your body in space.
Wait, how so?
you will lose muscle strength, endurance, and experience cardiovascular deconditioning since it does not take effort to float through space
Now that I think about it, simulated gravity through use of a cylindrical colony/space ship would actually work if you were to allow the cylinder to spin. Additionally, I'm pretty sure that's why people switch out from time to time on the ISS to avoid general health issues.
Even after returning to Earth, your bone loss might not be corrected by rehabilitation, so you could be at greater risk of osteoporosis-related fractures later in life.
Vitamin deficiency due to distance away from the sun? Oh, and also dust storms could technically cover up the sun from providing you with nutrients.
Gravity fields, isolation/confinement, hostile/closed environments, space radiation, and distance from Earth.
I think these are hazardous because:
confinement with three co-workers picked to travel with you by your boss.
Now that I think about it, the Apollo crew and others had no decision on which groups they were apart of, or necessarily needed to establish relations with new people (which in my opinion, would be very hard.)
has been unfolding answers for over a decade.
Not very simple to figure out, despite our current experience with space, aka the extended stay in space longest being I think around 3 years, which I'm pretty sure they did research on the effects.
It’s widely accepted that there won’t be another “Apollo moment” for our space program. NASA will probably never receive the amount of funding it did when JFK set his sights on the Moon.
Agreed, though weirdly enough, the Artemis program is officially starting in 2024, and there is already a lot of funding, luckily.
Budget cuts are delaying the development of the Commercial Crew program, which would get astronauts launching from American soil again. In the meantime, we’ll be forced to continue buying tickets on the Russian Soyuz.
It's confusing that they continue to be delayed through lack of funding, but the dependence on other countries, regardless of how we started off space exploration being dependent with the country. But at least some independent support from themselves would be better.
Since 1972, NASA’s budget hasn’t increased, but has been cut by roughly 75 percent, and it’s stayed that way for 42 years. While the Apollo era budget was arguably not sustainable, it raises questions as to what might be possible if NASA once again had access to more financial support.
Considering it was dramatically cut to 25% shows how much funding and how much encouragement and enthusiasm JFK had of the Apollo program, and I think nowadays without any inspirational value the cost was cut low.
That's minor fees per year, but the prices eventually stack up due to operation costs, and all that.
How did New Horizons, a simple machine made for literally going to PLUTO and needs to be built to withstand forms of environmental/intergalactic debris literally only cost 7,000,000, while Cassini, a machine just for investigating Saturn and eventually dived into it for a dramatic re-entry (no literally), that cost 3.3 billion, it's an even larger cost then Horizons, wow.
$20 per year to NASA. JFK needed that number to go up to $26 a year to help get our astronauts to the Moon. In 2015 dollars, the Apollo era budget would have been equivalent to each American paying over $200 a year to the space administration. If NASA still had that sort of funding in 2015, that would make its budget a whopping $65 billion dollars per year, compared to its actual budget of $17.5 billion.
That is an incredibly dramatic difference for just 6 dollars more than the original amount.
That’s not even a percent of the total 3 trillion dollars allocated to the U.S. in 2014.
I'm confused on how why they earned 3 trillion yet only provided .5 percent to a governmentally linked organization.
But exploring isn’t free, especially not in the space case. What is the price of awe and amazement?
This quote kind of shows to me that you actually could theoretically buy happiness.
On July 14th it seemed as though the world stopped
It seems as though many, and I mean MANY people are united by a single concept of space and generally the fascination of it, and I'm glad that we've made it, because there's still a lasting impact of inspiration on the onlookers.
And while no one could see the spacecraft, we all watched in awe as the nine-year journey came to a close
Using the word came to a close is kind of unreasonable, there's still more things ahead of us, after all, since we've merely just crossed a decade long boundary.
Recently, the world was united once again in the spirit of space exploration as the New Horizons spacecraft flew by Pluto.
This really puts into perspective how far humanity has come, from merely making up tales of green men from interstellar/celestial bodies, and now, look at us, we've reached the very end of the solar system and now we're traveling beyond it with the existence of the Voyager twins, the Pioneer twins, and New Horizons.
the Voyager 1 spacecraft turned around on its way out of our solar system, and took the ultimate family portrait. This time, from a distance of 3.7 billion miles away, we were tiny, just a speck among the stars.
Voyager 1 and the other probes that have no other purpose than to go outside the solar system really kick a perspective into mankind, and to (indirectly) quote Carl Sagan, 'Many people have fought wars, killed, just for this small, blue dot in an endless expanse'
Upon signing the Space Act
The Space Act does refer to the peaceful usage and non-weaponization of space, but I also originally thought that JFK was the starter to the fire/career that is space exploration, so it's partially surprising. Also, I'm pretty sure the predecessor of NASA was the one created, aka NACA.
After the launch of Sputnik in 1957, President Eisenhower realized we were losing the space race
Sputnik kind of served as the disaster to the entire idea of space exploration, think about it. Sputnik was the VERY FIRST big step within the territory of space exploration, and is a even larger deal than rockets, forms to exit the atmosphere and enter earth's orbit, etc.
it turns out we are actually getting a great value from this government-run agency.
This most likely is true considering the contributions the space agency and generally the ideal of space exploration has given us, take for example photographic imagery and geologic structures on maps, but also tidal maps, wind maps, temperature maps, and I think also weather maps.
We’ve successfully put laboratories onto the surface of Mars,
Considering the multitudes of landers that have landed on mars to conduct experiments upon the soil, rocks, and land, I think that those are basically the labs that this article has been talking about, considering inflatable habitats have not been established and we haven't even landed on the moon for real yet, or at least haven't established a colony.
