Rocket Science: Aerospike Rocket Engine Applications

Aerospike rocket engines are more efficient than anything flying today...
Why did NASA spend $500 million developing aerospike technology and over $1.2 billion constructing an advanced spacecraft to use them then cancel everything? Is there a fundamental flaw in aerospike technology? Or did politics and fear of innovation cause the US to turn its back on a technology absolutely necessary for our ships to function on other worlds? How can a de Laval nozzle optimized for Earth operate efficiently on Mars, the Moon and Titan?
The Terran Space Academy walks you through rocket engine nozzle technology covering overexpanded nozzles and underexpanded de Laval nozzles, and compares it to annular and linear aerospike technology.
Thank you so much for watching!
