Space missions demand extreme precision in fluid measurement and control, particularly at low flow rates.
Key challenges include:
1. Detecting microscopic leaks in critical sealing systems
2. Maintaining high repeatability in validation processes
3. Ensuring system integrity in life-support and propulsion systems
4. Operating reliably in high-stakes, zero-failure environments
In these scenarios, even the smallest undetected flow can compromise mission safety.
In NASA’s Artemis missions, Brooks SLA Series mass flow controllers are used for critical O-ring leak testing of booster rockets. These systems verify that seals prevent any unintended flow past designated thresholds, ensuring the integrity of propulsion systems during launch.
Key Benefits:
On the International Space Station (ISS), the Quantim® Coriolis mass flow controller supports the rehydration and generation of saline solution, enabling astronauts to receive intravenous fluids on demand.
Key Benefits:
Following the Challenger accident, NASA implemented enhanced leak detection systems for the Space Shuttle Solid Rocket Motor (SRM). A Brooks Instrument thermal mass flow meter was incorporated into the improved system to ensure more reliable detection of O-ring seal integrity.
Key Benefits:
Brooks’ legacy in space exploration dates back to the 1960s, when Sho-Rate® variable area flow meters were used to leak-test NASA spacesuits during the Gemini and early Apollo programs.
These instruments are visible in archival imagery, including a 1962 Norman Rockwell painting depicting astronauts Virgil Grissom and John Young during Gemini mission preparation. The presence of Brooks instrumentation highlights its role in ensuring astronaut safety from the earliest days of human spaceflight.
Key Benefits:
Reliable visual flow indication
Brooks Instrument solutions are designed to deliver:
As demonstrated across decades of NASA missions, these capabilities are essential where failure is not an option.
