NASA engineered the James Webb Space Telescope (JWST) to withstand continual bombardment from dust-sized particles moving at extreme velocities, known as micrometeoroid strikes. To date, JWST is averaging one to two strikes a month.

Although both Planetary Protection and Planetary Defense programs at NASA include the word “planetary” and aim to protect the planet, that’s where similarities end. These two vital efforts oversee very different aspects of the agency’s role in protecting Earth, and in some cases, other planets. 

The Mars Ingenuity Helicopter will take its first steps toward demonstrating powered flight in the Martian atmosphere, with a first attempt at a powered, controlled flight of an aircraft on another planet scheduled for no earlier than April 8, 2021. The helicopter rode to Mars in the Perseverance Rover's belly pan and will be deployed for flight testing from the red planet's surface in April. 

NASA uses the Programmable Josephson Voltage Standard (PJVS) to ensure the agency’s calibrations include the most accurate voltage measurement with the lowest measurement uncertainty possible. 

Langley Research Center is actively using state-of-the-art Nondestructive Evaluation (NDE) modeling and simulation tools to accelerate the adoption of advanced materials and ensure the safety of aging infrastructure.

The Mars 2020 mission, including the Perseverance Rover and Ingenuity Helicopter, will land on Mars on February 18, 2021. A first on a Mars mission, the Sample Caching System included on Perseverance will collect and store short cores of Martian rocks and soils destined for future return to Earth and study with advanced instrumentation. The system is complex, including a drill for sample collection and tubes to seal and store the collected samples until a future mission can retrieve them.  

NASA projects go through the full life cycle, from concept to implementation to closeout, with a number of reviews along the way. These reviews ensure that the developed project can meet mission objectives and do so safely. The project must make a case for itself: show and explain why the system will work as intended. Enter, the safety assurance case, or simply safety case as it may be more commonly known. Researchers at Ames Research Center have been fine tuning their notion of the safety case and developing a tool to make its development easier.

In recent years, the Office of Safety and Mission Assurance (OSMA) Pressure Systems program accomplished a number of efforts to facilitate broader use of NASGRO for the analysis and sustainment of pressure systems. By expanding the use of NASA’s perpetual, royalty-free NASGRO license, centers across the agency will realize a significant cost savings.

When working with explosives, it’s essential to fully understand the hazards and potential risks to employees and facilities in the area should something go wrong. However, it’s also possible for non-explosive materials to become energetic in a way that poses similar, potentially deadly and damaging risks. These high-risk operations — whether relative to “traditional” explosives or energetic materials — need to be properly managed to ensure a safe work environment. How Explosives Safety Officers are assessing and managing that risk varies from center to center to accommodate the diverse environments and work being done. The following examples show how three unique NASA centers and facilities are managing these risks.

The Safety and Mission Assurance Directorate at Goddard Space Flight Center developed an integrated platform, the Meta information system, which currently encompasses 22 operational applications for Goddard and NASA Headquarters’ Science Mission Directorate.
