Monopropellant

A monopropellant is a type of fuel used in spacecraft and rockets that can produce thrust on its own without needing an additional oxidizer. When exposed to a catalyst or specific conditions, it rapidly decomposes, releasing gases that generate thrust to propel the vehicle. This simplifies rocket design since only one substance is needed, making monopropellants efficient for small adjustments or maneuvering in space. Common examples include hydrazine and hydrogen peroxide. They are valued for their reliability and ease of storage, despite sometimes posing handling hazards due to toxicity or stability concerns.
