NEPP Investments and Their Impact on Ingenuity’s Success

4-minute read

NASA’s Ingenuity Mars Helicopter made headlines in April after successfully completing the first powered controlled flight by an aircraft on a planet besides Earth. Ingenuity’s tremendous success demonstrates the continuing evolution of NASA’s Risk Management processes for infusing commercial technologies into space missions. While rightly described as a “high-risk, high-reward” technology demonstration, Ingenuity is completely based on well-reasoned and disciplined engineering analysis and methodical risk identification and mitigation schemes.

Yes, If Program

At NASA, safety is our first priority. When the possibility of something comes into question, our response should begin with, "Yes, if" instead of "No, because." Those who have exemplified this spirit of ingenuity, creativity and commitment to safety have received the "Yes, If" coin from the current chief of Safety and Mission Assurance. Recognize a NASA colleague who you believe should earn a "Yes, If" coin.

Lessons From Challenger

This Jan. 28, marks the 35th anniversary of the Challenger accident. The loss of the crew was a tragedy felt by their families, friends and coworkers at the agency, as well as people throughout the world.

The Challenger accident taught us tough lessons and brought forward what have become recognizable phrases: normalization of deviance, organizational silence and silent safety program.
