- Helium pressurizes fuel tanks and supports cooling systems essential for rocket engine functionality.
- Its small atomic size causes leaks, which have affected missions such as Boeing’s Starliner and ISRO’s Chandrayaan 2.
- The gas is inert, non-toxic, and remains gaseous at extremely low temperatures, making it ideal for space applications.
- While alternatives like argon and nitrogen are explored, helium remains the preferred choice in the aerospace industry.

- Boeing's Starliner will remain docked at the International Space Station (ISS) for the time being as engineers analyze data from the vehicle's propulsion system.
- Originally scheduled to leave the station and land in White Sands, New Mexico on June 25, the spacecraft's undocking has been postponed once again without a specified new date.
- With two spacewalks from the ISS planned for June 24 and July 2, the next departure date could potentially be in July or even pushed back to August.
- The delay aims to avoid conflicts with upcoming spacewalks and provide engineers with more time to assess data from the Starliner's propulsion system.
NASA delays Starliner return a few more days to study data: “I would not characterize it as frustration. I would characterize it as learning.”

- Boeing launched astronauts for the first time on Wednesday, becoming a second NASA taxi service alongside SpaceX.
- NASA test pilots Butch Wilmore and Suni Williams flew aboard Boeing's Starliner capsule to the International Space Station, spending just over a week in orbit before landing in the western U.S. on June 14.
- Despite delays due to spacecraft flaws, Wilmore and Williams expressed full confidence in Boeing's capabilities for this test flight prior to launch.
- Boeing and SpaceX were hired a decade ago by NASA to ferry astronauts to and from the space station, with SpaceX successfully sending astronauts into orbit in 2020.
NASA finds more issues with Boeing’s Starliner, but crew launch set for June 1: Fixing the helium leak would delay Starliner crew test flight for months.
