The U.S. space agency is looking to replace the highly toxic hydrazine propellant by another less dangerous to humans and the environment. It has launched researches in this direction.
To reach the highest layers of the atmosphere and move in space, a rocket, satellites and other spacecrafts need non-conventional types of fuels. Since missiles from the World War II and until now, it was understood that the propellant was hydrazine.
But the Hydrazine is highly toxic and corrosive. Also, NASA decided to substitute it by less harmful fuels. Michael Gazarik, director of the Space Technology Program at NASA, which aims to develop space technology has recently said, "High performance green propellant has the potential to revolutionize how we travel to, from and in space,"
So after a solicitation, Ball Aerospace’s technology has been selected for a series of tests in the program called "NASA's Green Propellant Infusion Mission" that will last three years and whose cost is estimated at 45 million $.
"An effective green rocket fuel would dramatically reduce the cost and time for preparing and launching space missions while decreasing pollution and harm to our environment."
