Is there a space exploration race among BRICS nations?
On Sunday, India became only the fourth country in history to employ scramjet engines in the launch and propulsion of space rockets.
Scramjet technology relies on hydrogen as fuel while oxygen from the air is used as an oxidizer to burn the fuel. Combustion occurs externally while the craft is moving at supersonic speeds.
