Eighteen of these advanced concept proposals were categorized as
Phase I and 10 as Phase II. They were selected based on their
potential to transform future aerospace missions, enable new
capabilities, or significantly alter and improve current
approaches to launching, building and operating aerospace
systems. The selected proposals include a broad range of
imaginative concepts, including a submarine glider to explore
the ice-covered ocean of Europa, an air purification system with
no moving parts, and a system that could use in situ lunar
regolith to autonomously build concrete structures on the moon.
“These selections represent the best and most creative new ideas
for future technologies that have the potential to radically
improve how NASA missions explore new frontiers,” said Michael
Gazarik, director of NASA’s Space Technology Program at the
agency’s headquarters in Washington. “Through the NASA
Innovative Advanced Concepts program, NASA is taking the long-
term view of technological investment and the ad
