NASA Gives The World a Brake

3 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) Current brake system technology cool disc brakes with air pulled from inside the vehicle’s body to prevent overheating. The channels cut into the exterior of the disc brakes developed by Orbis Brakes draw in external air, which is cooler, ensure the brakes work more […]

Key Considerations When Developing Avionics for Safety-Critical Systems

This article is from the 2024 Technical Update . Multiple human spaceflight programs are underway at NASA including Orion, Space Launch System, Gateway, Human Landing System, and EVA and Lunar Surface Mobility programs. Achieving success in these programs requires NASA to collaborate with a variety of commercial partners, including both new spaceflight companies and robotic […]

6DOF Check Cases

This article is from the 2024 Technical Update . In 2015, the NESC released benchmark Earth-based check-cases for well specified, rigid-body, six-degree-of-freedom (6DOF) aero/spacecraft models to promote consistent and accurate flight simulations across multiple Agency tools and facilities. Recently, the NESC expanded upon that effort to add Lunar-based check-cases to support new lunar exploration initiatives. […]

Helium Conservation by Diffusion Limited Purging of Liquid Hydrogen Tanks

This article is from the 2024 Technical Update. The NASA Engineering and Safety Center (NESC) has developed an analytical model that predicts diffusion between two gases during piston purging of liquid hydrogen (LH2) tanks. This model helps explain dramatic helium savings seen in a recent Kennedy Space Center (KSC) purge, shows that undesired turbulent mixing […]

Considerations for Using Autonomous Flight Termination Softwarein Crewed Launch Vehicles

This article is from the 2024 Technical Update Autonomous flight termination systems (AFTS) are being progressively employed onboard launch vehicles to replace ground personnel and infrastructure needed to terminate flight or destruct the vehicle should an anomaly occur. This automation uses on-board real-time data and encoded logic to determine if the flight should be self-terminated. […]
