Hydrogen Flame Detection Methods:
NASA rockets rely on liquid hydrogen and oxygen for fuel, maximizing tank volume for lift. But if the highly combustible hydrogen leaks, it can lead to a massive explosion.

NASA struggled with hydrogen leaks, grounding the Space Shuttle program for months during the "Summer of Hydrogen." Hydrogen's invisible flame in daylight posed a challenge.

Engineers used a low-tech solution during the Apollo missions—walking with a broom. When the broom touched burning hydrogen, it combusted, revealing dangerous areas.

Later, NASA employed sensors and ultraviolet cameras for leak detection, providing better accuracy. However, visual indicators were still lacking.

Collaborating with the Florida Solar Energy Center, NASA developed chemochromic tape that changes color in the presence of hydrogen, offering immediate leak detection.

Hydrogen leaks remain a concern, as seen in the aborted Artemis 1 mission. NASA must address the challenge of the most efficient fuel being the most dangerous to prevent future leaks.
