Loss of taste is a problem for the astronauts since their nasal passages become congested due to weight shifting to the upper body and the head.  Space agencies use, "techniques that include food thermo-stabilized with heat to destroy microorganisms that may cause it to spoil, dehydrated foods to reduce volume and the survival rate of microorganisms, natural form foods such as nuts that are already stable, and beverages."

But astronauts in space usually do not feel its effects.  The longest time spent in zero gravity was 437 days by Valeri Polyakov 20 years ago. Currently we do not know how long you could stay in zero gravity before your bones would completly give away. We currently bellive that if you spent too long without zero gravity then your neck would not be able to soppurt your skull and your head would collapse along with the fact that if you bones deteratied too much you would never recover. As well as a loss of your skeletal system  your immune system would suffer under long exposer to zero gravity. You would feel unwanted autoimmune responses and hypersensitivity. Finally Even on Mars the gravity there is theses than that on earth meaning astronuaghts would still loos mass on the red planet.The average time spent in spade is 6 months muc h longer than a trip to mars so something must be done to either replicate gravity or shorten the distance to mars in order to protect our astronaughts. ]]> 2018-03-09 15:30:34 UTC https://padlet.com/andrea_bell2/mlchwkpg6jsh/wish/240202924 Owen Brethauer - Space Suits breto7376 https://padlet.com/andrea_bell2/mlchwkpg6jsh/wish/240202983 NASA seems to be running out of the space suits it does have for the astronauts on the ISS.

As NASA looks further into food on Mars, they have realized that most food won't last more 5-8 years for the trip to mars. So they were thinking about growing plants. But I think that if they can find away to get livestock to Mars in the future they won't have to find ways to send food to Mars every year.

I feel that zero gravity is the most important topic because when you get back to earth, it still affects you because your muscles aren't as strong as they were before, even to the point of you don't have enough strength to stand and this could take month to years to get your strength back to do just the little things like stand and walk

Astronauts have lots of problems moving around because of how stiff the suit is. Another trouble with space suits is that they need to be full of air which is actually the reason it is difficult to move in. As an astronaut would keep going higher and higher the pressure would decrease and so would their need for air which is why the suit is pumped full of it. Nasa is working on a better space suit that will be able to keep astronauts alive while being able to move.]]> 2018-03-09 15:31:34 UTC https://padlet.com/andrea_bell2/mlchwkpg6jsh/wish/240203518 Radiation - Zoha Awan https://padlet.com/andrea_bell2/mlchwkpg6jsh/wish/240203587  A very big problem for humans and space travel is the risk of radiation. On Earth we are protected by the planet’s natural radiation shield, the magnetic field that surrounds our world which blocks out 99.9 percent of the harmful radiation from the Sun and deep space. Radiation is obviously not healthy for humans. In space radiation is in the form of subatomic particles that can come from the Sun and further out in the Universe including the Milky Way Galaxy and even beyond. They are moving at high speeds and can rip through our DNA molecules causing damage or splitting within them which can lead to cancer and other diseases. In the International Space Station astronauts stationed there for the average of six months will be exposed to roughly 100 milliliters of radiation.  Mars has no global magnetic field to deflect energetic particles, and its atmosphere is much thinner than Earth's, so they'll get only minimal protection even on the surface of Mars. Throughout the entire trip, astronauts must be protected from two sources of radiation.

Meteoroids can be man made (satellites) or natural (rocks). If they are moving at high enough speeds then they could go through spaceships/shuttles/satellites. This is dangerous for astronauts because if a meteoroid pierced a spaceship the oxygen inside the spaceship could leak out and everyone would die. Nasa is trying to find a way to stop the meteoroids from going all the way through the ship by layering metal and foam in the hopes that it would slow the meteoroid enough that it would be unable to hurt anyone inside the ship.

This may seem fun at first, however, the weightlessness causes one's muscles and bones to weaken and lose a detrimental amount of strength. The cause of this is the fact that when in zero gravity, your muscles aren't used as much as they are on Earth. This loss of strength causes astronauts to be extremely weak once they return to Earth.

To combat this, scientists created exercise machines that can be installed inside spacecrafts. Astronauts can use these as a way to keep using their muscles and bones to stay as strong as possible while in zero gravity. This way, when astronauts return to Earth, they are not nearly as weak as they would be without having used their muscles at all.]]> 2018-03-09 15:32:27 UTC https://padlet.com/andrea_bell2/mlchwkpg6jsh/wish/240204075 Zero gravity- Mila jozkm4859 https://padlet.com/andrea_bell2/mlchwkpg6jsh/wish/240204076 A  high risk of going to space it the fact that so far we have not found a way to create fake gravity in space now this a problem because when you are in zero gravity far long amounts time your muscles and bone start to break down because they are not needed as much and even when you workout in zero gravity it still doesn't apply that same amount to presser to the body, air weighs 14.7 pounds per square inch at sea level. the way we know that air has a weight is because you can feel the wind we just are accustom to the amount of presser in our region. this may not seem like a problem when you are in zero gravity but when you come back from your mission you will not have enough strength with our amount of gravity and you will not be  able to build the bone and muscle tissue again.]]> 2018-03-09 15:32:27 UTC https://padlet.com/andrea_bell2/mlchwkpg6jsh/wish/240204076 Zero Gravity- Vanessa millv4492 https://padlet.com/andrea_bell2/mlchwkpg6jsh/wish/240204104 Zero gravity in space is important to talk ]]> 2018-03-09 15:32:29 UTC https://padlet.com/andrea_bell2/mlchwkpg6jsh/wish/240204104 Zero Gravity- Brandon glydb5495 https://padlet.com/andrea_bell2/mlchwkpg6jsh/wish/240204190 As an astronaut, you encounter several problems while floating around aimlessly. Some of these occurences are damage to the heart, musculatory system, bone structure and visual imparement. Having an occupation such as someone who goes to space, this could be quite the challenge after a while. Some of the main conclusions to this problem is artificial gravity. As of right now, artificial gravity is possible by spinning the spacecraft or station fast enough, causing the centrifugal force to push back mimicing gravity. ]]> 2018-03-09 15:32:38 UTC https://padlet.com/andrea_bell2/mlchwkpg6jsh/wish/240204190 Food in space- Caitlyn Prosser https://padlet.com/andrea_bell2/mlchwkpg6jsh/wish/240205314 Food is essential to survival in space. It is what keeps us functioning throughout the day. However over time no matter how many preservatives are put into the food, it begins to lose nutrients, taste and texture. In other words it starts to expire. How NASA is attempting to solve this problem is by thermo-stabilizing their food or it  is freeze dried and keeps out any air or water that might expire the food . This rids the food of any micro-organisms that might cause the food to go bad over time .]]> 2018-03-09 15:34:28 UTC https://padlet.com/andrea_bell2/mlchwkpg6jsh/wish/240205314 Radiation - Gurleen Katnoria katng4324 https://padlet.com/andrea_bell2/mlchwkpg6jsh/wish/240206097 2018-03-09 15:35:29 UTC https://padlet.com/andrea_bell2/mlchwkpg6jsh/wish/240206097 Zero gravity- Jordan King https://padlet.com/andrea_bell2/mlchwkpg6jsh/wish/240206427 When is space, Your spacecraft lacks garvity causeing you to float. when you are on earth your body has to use muscles more to do dimple things like walking. But when you are in space with zero gravity, your body doesn't use all of the muscles and even bones to do simple things.

Scientists are trying to fix this by creating excersising rooms that spin to act like gravity in space. This would help because you would have to use all of your muscles and bones to excersise. So when you come back down on earth, there will be less impact when you feel gravity.]]> 2018-03-09 15:35:58 UTC https://padlet.com/andrea_bell2/mlchwkpg6jsh/wish/240206427 https://padlet.com/andrea_bell2/mlchwkpg6jsh/wish/240387085 2018-03-09 22:34:13 UTC https://padlet.com/andrea_bell2/mlchwkpg6jsh/wish/240387085 Meteoroids - Fares Fadl fadlf7686 https://padlet.com/andrea_bell2/mlchwkpg6jsh/wish/243643006 Space is littered with small fragments of comets, asteroids and planets, called meteoroids. In the vacuum of space, they reach deadly speeds, at about 20,000 kph. If a meteoroid in space would have hit a spacecraft it could potentially cause a loss of power, damage it, or may even  kill who ever is behind the wall, it smashed through. Now at NASA they are testing new lightweight shielding for the walls of a spacecraft. It is a smartly designed shield, and what happens is that because the velocity is so fast, when the projectiles impact the shield, the speed breaks it apart, and then the rest of the target will absorb the impact. This is a new design that NASA will hopefully start using to prevent meteoroids, from ruining space missions, or even injuring astronauts in space. But meteoroids are only a peril of many other dangers in space.

The suit is really a small spacecraft. It protects the astronaut from the dangers of being outside in space.” The suits protect them from getting too hot or cold, give them oxygen to breath , hold water, protect their eyes from the sun, and protects them from space dust. The suits are very heavy and are hard to move around in, they are stiff and awkward. They are difficult to do activities in and the astronauts use most of their energy just trying to move around in the suits. The suits need to have enough pressure in them to keep you alive, it is very hard to get the amount of pressure needed. Your space suit is your main protection. These are key in traveling in space. Without wearing proper space suits your body would not be able to withstand the elements of space, you would die. Space engineers are working on designing new suits that provide the pressure needed but also allow you to move freely. The suits are skin tight and are made with a new product called “smart wire”. These suits would take less energy to move around in and let the astronauts get what they need to get done faster and easier.

The Advanced Resistive Exercise Device allows astronauts to do weight-lifting without "maxing out" their top weight. It has also been linked to better outcomes in bone density and muscle strength. Astronauts typically have an exercise period of two hours a day to counteract these effects. This time includes cardiovascular exercise, weight-lifting, and also time to change clothes and set up or take down equipment. Despite exercise, it still takes months of rehabilitation to adjust to gravity on Earth after a typical six-month space mission.

Some people may not believe this to be true, but clearly they have never talked to an astronaut who has spent, in excess, of four to five months in a zero gravity environment. Some astronauts who have spent only 5 months in space (I say only because humans have stayed in space for up to 437 days and 18 hours) have experienced muscle and bone mass loss of up to 45% in that, relatively speaking, short amount of time. A solution, or at least a way to limit the effect (to an extent) of a zero gravity environment, is to be physically held down by straps to a piece of exercising equipment and work out like that multiple times a day, every day. Some astronauts do not believe that this method is very effective, if at all effective, thus, another (more expensive, but pretty cool) solution would be to create a new space station that spins! To a simple minded person, this may seem stupid as it would just throw the astronauts all over the place, right? Not quite the case! The spinning effect of a spacecraft would have the same effect as the rotation of the Earth. The spinning creates centrifugal force, pushing anything and everything away from the centre of the area contained within the spinning craft. This centrifugal force created by the spinning motion would act as a force of gravity on the objects within the craft. The gravity would not be automatically the same as the gravity on Earth if the craft spins only slightly though. The exact rotation speed of the craft would to be calculated and calibrated accordingly throughout the time that the craft is occupied by humans to keep the current occupants comfortable and safe. If the spinning was not regularly adjusted, it could go out of control, forcing every object onboard (including humans) to be forced as far away from the centre of the room as possible, essentially "pinning" everything against the walls without them having the ability (in the case of humans) to even move their heads. On the other hand, if the spinning motioned slowed too much, could cause everything to float into the air, creating a big mess everywhere, or even in the worst case scenario, getting into electrical and/ or water systems, causing shorting outs, or blockages.

Since heat and respiration is reduced leading to progressive loss of body weight, and bone calcium. Without the downward pressures of gravity, height increases, and body mass decreases with a loss of muscular tissue. Astronauts feel weaker upon return to Earth. Although, these effects are easily reversible after short missions, within a week or two being on Earth. The most serious concern is the loss of bone calcium, some scientists believe we should find a way to simulate Earths gravitational force in space missions. ]]> 2018-03-23 11:50:56 UTC https://padlet.com/andrea_bell2/mlchwkpg6jsh/wish/245403983 Food in Space- Chantelle Balke balkc5710 https://padlet.com/andrea_bell2/mlchwkpg6jsh/wish/245469084 Food in space is a huge challenge for astronauts. Things that are very lightweight will float away immediately and spill, such as liquids if you don't handle them properly. Things that are crumbly are not good in space either because small pieces of food break off and go into people's sleeping spaces and other places they shouldn't be. Food in space sometimes needs to be re-hydrated in order to improve taste and nutrition. "If I wanted to suck vile fluids out of a flaccid and indifferent tube, I'd have stayed on Earth with my husband.”
― James S.A. Corey, Abaddon's Gate. Food in space is typically not enjoyable and more for energy and nutrition. There are very limited things that are portable enough to travel to space, and they must be handled very carefully in order to make it all the way there. Astronauts eat 3 meals a day, same as you typically would on earth. Nutritionists make sure to provide astronauts with a healthy, balanced diet with necessary vitamins and minerals as well.

For example, bones and muscles can be weakened, and there are also some other effects that can happen due to it. Astronauts can experience a disruption in their proprioceptive system, which tells where arms, legs and other parts of the body, this can cause them to feel queasy. Some longterm effects are that as the bones weaken due to calcium secretion, they can break a lot easier if they fall. These effects are all caused by there being zero gravity in space. They can't feel the effects of gravity on their body so in results the astronaut's bones, and muscles weaken. The way they combat this is by having an allocated exercise period of two hours a day during this time they do cardiovascular exercise and weight-lifting. Another way to combat this issue is by creating a room that spins. By doing this it forces everything in the room towards the wall acting like an artificial gravity. Astronauts can use these rooms to workout. Despite exercise, it still takes months of rehabilitation to adjust on Earth after a typical six-month space mission.For example, Chris Hadfield said "Just holding my head up is a bizarre new experience (www.smithsonianmag.com, 2016). Overall zero-gravity can have many effects on the human body.

Meteoroids as small as a pebble may be travelling at more than 20,000mph, and if that pebble was to come into contact with a spacecraft, then the lives of the people on board could be lost.
While this is a very dangerous issue, scientists have discovered a way to combat the dangers of these meteoroids.
Researchers have come up with a foam shield built to combat these micro meteors. The foam shield has a hard surface, which will break apart the meteor, then the meteor will be collected in the foam interior and stopped before it can reach the interior of the spacecraft, thus making space travel the slightest bit safer.

  • Compact: Space is very limited on board the ISS.
  • Lightweight: Sending goods into orbit is extremely expensive.
  • Nutritious: The food must contribute to the healthy diet of the crew.
  • Tasty: Astronauts' sense of taste is reduced in microgravity.
  • Sticky or wet: In the absence of gravity, crumbs and particles float freely.
  • Processed or pasteurized: The food must keep for at least the entire duration of a mission
