Space explorers who need to recharge the fuel tank while in transit to the Moon or Mars in the near future will be able to come to fueling stations in orbit.
Reportedly, NASA provided a U.S. $ 200 million or approximately Rp1, 7 trillion for those who were able to show how to store and transfer fuel rocket in space.
The idea to open a petrol station in outer space itself has long been developing. For example, a Canadian company preparing to launch a refueling station in the year 2015.But the proposal, NASA wants something more than just recharge the spacecraft in Earth orbit.
Excerpted from the Innovation News Daily, May 23, 2011, NASA wants to specifically utilize oxygen and liquid hydrogen which is used to supply power for spacecraft engines and some commercial rockets. The proposal offered by looking for companies that can provide storage 'zero-boil off' liquid oxygen storage and at least 'minimum boil-off' of liquid hydrogen.
As an illustration, the liquid hydrogen storage requires a temperature of minus 218 degrees Celsius. Substances that need to be protected from external heat sources such as solar or waste heat rocket engine to prevent it from occurring expansion or storage tank caused the explosion.
Interested companies to welcome the challenges NASA must also be able to show how the liquid is transferred in a minimal-gravity environment of Earth orbit.
Although the proposals reached a value of USD 200 million, the United States space agency would consider the mission whose value reached USD 300 million. Condition, the additional cost it offers important advantages. Instead, NASA is also considering a proposal valued at under $ 200 million provided that fully meet the requirements.
NASA partners who managed to provide the technology to bring the gas station in outer space itself will benefit from a main refueling stations are.
For information, at this time, NASA is also working with a private rocket company from the United States, Space Exploration Technologies Corp. (SpaceX). They are contracted to deliver astronauts and cargo to the International Space Station. But not to deliver humans to the Moon and Mars.
