Experiments are being conducted in microgravity to try to understand the effects it has on objects. Experiments on fluids are being performed to try to better understand how they flow in microgravity (Illustrated 219). These fluids will help engineers to build earthquake-resistant buildings, increase productivity in materials processing, and performance of power generating sources. Science on combustion is performed to better understand the ways to improve combustion efficiency, reducing pollution and transportation costs. Biotechnology experiments on protein crystals is being performed trying to achieve better medicines with fewer side effects (Microgravity 2).

On the ISS, astronauts do not get the fresh food that all of us are used to on Earth. Food is meant to be stored over a long time. It is stored in different forms like dehydrated, low moisture, heat-stabilized, irradiated, or natural. All this food is stored in food storage compartments in the galley or kitchen. Heat-stabilized food has to be prepared on food warmers to be able to be eaten. The food that is dehydrated or has low moisture has to have water added to it (Work 10).

volt DC current transformer. Some of the equipment onboard runs on AC current so there is power converters to fix that problem. Excess power from the arrays is used to charge the batteries for when the ISS passes through the Earth’s shadow (Work 11).

In outer space, cold temperatures vary throughout the ISS. Electronic equipment produces enough heat to keep the ISS heated, but the problem is the equipment produces to much heat. The problem is that excess heat is produced. A temperature control system was needed to distribute heat where it is needed and to get rid of excess heat. The first method to temperature control is the passive methods. This involves using insulation between rooms to minimize heat loss between rooms. Also, using electric heaters to heat small spaces. Next, putting liquid ammonia in a pipe to transfer heat from a warm area to a cold area. The ammonia evaporates at the warm end and goes to the cold end to give off heat (Work 9).
