99.9%24 Feb 2026 20:05
Apologies if I have missed this angle in recent discussion.
Can we assume that Elon Musk and NASA know of HEX’s 99.9% Helium?
N.B. From AI.
High-purity (99.9% and higher) helium is considered vital and mission-critical for space exploration. It is not used for breathable air, but its unique physical and chemical properties make it indispensable for rocketry and satellite operations.
Why High-Purity Helium is Vital in Space:
• Rocket Fuel Pressurization (Ullage): Helium is used to displace liquid fuel and oxidizers in rocket tanks. Because it is inert, it does not react with the volatile fuels, making it safe for preventing tank collapse and ensuring proper fuel flow.
• Cryogenic Cooling: Liquid helium is used to cool equipment to near absolute zero, which is essential for sensitive sensors on space probes, telescopes, and satellites.
• Leak Detection: Due to its tiny atomic size, helium is used to test for leaks in high-vacuum and high-pressure equipment.
• Purging Systems: It is used to purge fuel lines in ground support equipment before launch.
Why 99.9% Purity Matters:
While helium is the second most abundant element in the universe, it is rare on Earth. High-purity, processed helium is necessary because impurities can cause issues in sensitive, ultra-low temperature, or high-pressure environments.
