My Experience at Aviation Challenge and Space Academy -Aviation Challenge- Day 1 When I first arrived at Aviation Challenge, I was expecting a very laid-back camp in which we get to do military style activities, but boy was I wrong. By the end of the first day, I had concluded that this military-based camp was just like the military (who would have known). On the first day, we were divided into teams, given call signs (nicknames), and given Battle Dress Uniforms (BDUs). My team’s name was PPG
dissolving around 1-2% a month in astronauts . After longer periods, this can jeopardize missions if the astronauts do not have enough muscle or their bones are not strong enough to move safely . In order to prevent muscle and bone loss, NASA is using osteoporosis drugs and exercise . Exercises include an hour of cardio and an hour of weightlifting everyday . The exercise sends signals to the body to build muscle and bone, which resulted in astronauts returning with around the same amount
changes in stimuli, such as the visual systems ability to adapt in high vs low light environments. For the vestibular system we have no need to adapt because the primary stimuli has been a constant since our species first came into being. Here on Earth gravity pulls down on us with the same force no matter where we are standing. Occasionally we do experience a change in this state, like when we fly on aircraft, and during these moments we may experience distortions that cause; dizziness, vertigo
Due to the great development of science and people’s interest in astronomy,“Einstein’s general theory of relativity allows for the possibility that we could warp space-time so much that you could go off in a rocket and return before you set out” (Hawking). The access to internet allowed many people to gain huge amount of information and knowledge easily, including astronomy. Because of IT development, many people gain knowledge and found interest in the most mystical place, the space. Nowadays, movies
to the topic of medicine, but for the most part they utilized herbal ingredients and other natural remedies. Today, when we think of medicine we picture ground-breaking treatments in hospitals and labs filled with 3-D printers of organs and centrifuges spinning the latest vaccines. In the times of tribesmen and hunter-gatherers, the perception of medicine was quite different. These people believed that the body, the physical being, and the soul, the spiritual being, were meant to be treated as a whole
is a hazard that scientists have to keep in mind when making food. Also, it should be long lasting enough to last in space until a resupply. The food the astronauts eat in the International Space Station right now are all packaged food sent up from earth. There is freeze-dried food which is cooked before being flash frozen and vacuumed. This is then rehydrated with water when astronauts want to eat. There are wetpacks, which are food pouches that don’t need to be rehydrated like
significantly since the inception of the engagement ring the tradition surrounding the ring has not changed as much. As a result the market for gold rings shows no sign of slowing. Before gold is fashioned into beautiful rings it has to be mined from the Earth. In modern mining most gold comes from what are called load deposits.
remove physical, chemical and biological contaminants. Its objective is to produce an environmentally-safe fluid waste stream (or treated effluent) and a solid waste (or treated sludge) suitable for disposal or reuse (usually as farm fertilizer). Using advanced technology it is now possible to re-use sewage effluent for drinking water, although
