Context
India's human space mission Gaganyaan is likely to use a green propellant to avoid all toxic and hazardous materials as a propellant.
About
- What is Green Propulsion?
- Green Propulsionis a green alternative for the conventional chemical propulsion systems for future spacecraft.
- This is called a "green" fuel because when combusted it transforms into nontoxic gasses.
- Example: Hydroxylammonium nitrate (NH3OHNO3)fuel/oxidizer blend which is also known as AF-M315E is one example of green propellant
Significance
- Efficient:The green propulsion system seeks to improve overall propellant efficiency.
- Better performance: It delivers a higher specific thrustdelivered to per given quantity of fuel. It strives to optimize the performance of the hardware, systems, and power solutions.
- Easy & Safe: This is easier and saferfor storage and handling.
- Less toxic:It will reduce the handling concerns which are associated with the toxic fuel hydrazine.
- Lower cost: It requires a potentially shorter launch processing period and results in lowering costs.
