The depositories are placed in the orbit of the Earth or any other body to allow for spacecraft to take place. They may also be used to transport spacecraft for fuel in space. They occur in varying kinds depending on the type of fuel that is to be supplied, the location or the kind of propellant. These refueling activities are done by communication satellites, defense ministries, and commercial companies. The article below will explain more about propellant depots.
There are two steps towards refilling spacecraft in low earth orbits. They are propellant tanker delivery and the in-space depots. Both methods are still used to date and offer durable benefits thus assisting in normal performance of communication satellites. In a tanker delivery method, one tanker docks with the spacecraft transfer the propelling agent and depart. In an alternative method, many tankers are used which dock with the spacecraft and receive the propelling fluid.
This design of depots is an immature field and faces a variety of challenges. This has brought up the desire in researchers to come up with a perfect design thus motivating them to invest their energy and time in the research. The issues include propellant settling, transfer, usage for reboots among others. Transportation of fuel is complicated because of uncertain settling of liquids and gases in the tank thus slowing the process.
At zero gravity, the flow of gases and liquids is slow. The fluids float in pipes thus prolonging the refilling process. Upon the first transfer, the tanks are restocked with fuel for the next cycle. A large vehicle is mounted onto the tanker with a propulsion tug for a quick and easy top up. Varying methods are employed in the replenishing process, but the most common is the use of large vehicles to accumulate gases at high altitudes and later transport the same to distant orbits.
Another benefit of this invention of these repositories is that the manufacturing process becomes economical. The rockets are made are small in size and hence cost friendly. The traditional method involved the molding of large spacecrafts that could carry a large amount of fuel hence making them expensive.
Because the depositories are located on earth, they give the engineers a chance to advance and develop cheap refilling systems. The units are at their disposal and can thus interact with other engineers and sketch a design they assume could be promising. The previous method of creating spacecraft with individual tanks nullified the opportunity of researching.
Launching of storage tanks on earth enhances the performance of spaceship as the amount of mass they carry to the moon increases. The light carry payload gives the scientists a chance to explore deeper into space without interruptions of material damage in the heavy spaceships. They have a better chance of bettering their research as the light material is less prone to damage.
The depots are also important because they protect the stores with micrometeorites and bumpers which help retain both stability and altitude of orbits. Stability is achieved by poising the solar-shield to the sun direction, reporting the state and fuel condition to the earth. They also ensure that fuels do not boil away by maintaining their original low temperatures.
