- Thrusters use hydraulics to move the fuel, which is the liquid into the ignition. The pneumatic system, being combustible gas is ignition to the fuel. there are many different thrusters activated during stages of flight, for example, the two biggest thrusters fall of first. This process also uses hydraulics since the fuel then needs to be regulated into the next set of thrusters.
- Many on-board crew utilities use hydraulic systems. For example, since resources are limited in space, recycling is key. A hydraulics filter re-uses water from cleaning systems and showers for drinking, boiling water, and sanitary systems. This technology uses hydraulics by pushing water through a tube that goes through a very precise filtering system. There after pipes that circulate the whole ship uses hydraulic systems designed to be able to move around liquid even under the effects of zero gravity.
- Many on board life support systems and waste disposal systems rely on hydraulics and pneumatics. For example, oxygen circulation inside the crew bay is a pneumatic system. Since the oxygen is a gas, it is able to be moved around under pressure, in pipes and exit in vents.
- Waste disposal is a mix of pneumatic and hydraulic technology. When urinating, suction is created with air, being that urine does not go everywhere from the zero gravity. After waste containers are full, it is launched out of the space craft with pneumatic pressure or analyzed back at Earth.
- The manned maneuvering unit ( MMU ) is a pneumatic system that allows the user to cruise and explore space. This technology works with gasses under pressure, most commonly Co2, propelling the pilot up. Compartments squeeze air together that is sequentially released via the thrusters. This is very useful for exploring asteroids with good agility.
- Space stations are key in the advancement of humans in space. They all use hydraulics and pneumatics previously stated. Ranging from sanitation, living essentials, and maneuverability.
- When the lunar lander was about to arrive on the surface of the moon, it needed a huge counter to slow it and park it gently. A pneumatic thruster using combustible gas was used to safely land it.
- The surface of the moon was explored using a rover. It used basic hydraulic sytems such as brakes. These work by applying the pressure created by the water to the tire, creating friction and slowing down the rover.
- Astronauts exploring the moon needed a big assortment of life support systems. The primary life support system (PLSS) used many hydraulics and pneumatics. Everything needed for survival was included in the PLSS, including oxygen, temperature regulation, radio, removal of carbon dioxide , and waste disposal. Since the suit could get heated when close to the suns rays, tubes that circulate water pass close to the skin to cool the wearer down.
-This is a big jump in departments of science and engineering
-Creates new job opportunities for people interested with working in space
- Many people are happy with mankind's progress. When Neil Armstrong landed on the moon, thousands of people made signs and campaigns to show their bliss.
- Overall, positive effects are created
- Billions of dollars are sunk into research and development of space technology
- Government might raise taxes and ignore spending money on public attractions in order to afford space research
- The space race, which was a race to see which nation reached the moon first blinded leaders and governments into funding its population
- Overall negative effects are created
- Launching of the rocket, factories creating parts for space travel, and mining of resources needed to build these create masses of pollution
- Astronauts recycle everything in space, which might create a trend to people on Earth to do the same
Overall a balanced effect on the environment
In conclusion, hydraulics and pneumatics are very important in space. The zero gravity poses a new challenge that requires this new tech. Effectsare on margins, when economy is sacrificed for society.
Thanks for listening
