Human Spaceflight Knowledge Sharing: Innovation at NASANo Comment
Innovation often starts with stopping to look around.
Editor’s Note: NASA’s Office of the Chief Engineer and the Human Exploration and Operations Mission Directorate sponsored the Human Spaceflight Knowledge Sharing Forum in November 2016. Select individuals responsible for shaping NASA’s future over the next 10 to 20 years focused on technical best practices and lessons learned from successful and unsuccessful human spaceflight missions. This is part of a series of articles recapping lessons learned and knowledge shared by these individuals at the pilot knowledge sharing event.
NASA’s recent Human Spaceflight Knowledge Sharing Forum coincided with the agency’s Innovation Day, which sparked conversations around looking for different approaches to achieve success.
The infamous quote from the iconic movie “Ferris Bueller’s Day Off” set the stage for Kennedy Space Center Engineering Director Pat Simpkins’ presentation on innovation at NASA. “Innovation, to me, is about looking around,” said Simpkins, who referenced adventures from the 1986 movie. “I’m a big fan of stopping and looking around. And I’m a big fan of looking outside your swim lane.”
Simpkins shared stories from Apollo through ongoing work on Orion to demonstrate the significance of careful observation, usually beyond the focus of a launch or test.
“If you’ve been working in a system or a project or a program for such a long period of time, that’s your swim lane,” said Simpkins. “You’re an expert. Absolutely. But there may be stuff going on around you that you’re not noticing because you’re so busy keeping your head down and coloring.”
He said it’s important to be open to looking at other disciplines and experimenting with approaches that aren’t necessarily “how it’s always been done.”
Simpkins gave an example of an unusual method used to find the source of a water leak during processing of the U.S. Laboratory for the International Space Station. All the hardware was installed, processing was almost complete, and technicians discovered water in the bottom of the Environmental Control and Life Support System bay. They couldn’t figure out where the water was coming from and contemplated opening up the bay and starting over. And then someone recommended a simple, straightforward solution: lay down a brown paper bag and see where the water drips. It was a different approach to checking a leak –not listed in the ASME Handbook — and pointed them to the vicinity of the humidity separator where they isolated the leak, torqued the fittings, and fixed the leak.
Simpkins offered another example of an unconventional approach to problem solving. In order for the space shuttle fire suppression system to remain in a ready state, NASA had a requirement to verify that the fire suppression bottles in the crew module avionics bay were filled with fire-retardant fluid. The fire suppression bottles were solid-colored with no way to visually determine how full or empty they were. After struggling to figure out how to meet the requirement, someone came up with an idea to use hot air from an off-the-shelf blow dryer. They blew hot air on the fire suppression bottles, captured a photo with an infrared camera, and verified quantity based on the shadow line in the bottle. “It was a simple way, looking outside your typical space,” said Simpkins.
Wrong or Different
Simpkins says people have to get comfortable with the fact that there’s a distinction between different and wrong. “There are some wrong ways to do things, and maybe we’ve got enough scars and lessons learned to say, ‘Boy, we’re never going to do that again.’ And there’s also different.”
He offered the number of parachutes used for entry, descent and landing as an example. NASA has a lot of experience with three parachutes, but not with two or four. “That doesn’t make four wrong. It makes it different, and it’s something that we need to pay a lot of attention to, and I’m happy to say that especially the commercial crew team is asking those questions and looking at it from the point of view that there’s a difference between different and wrong,” he said.
In order to create an environment that allows innovation to flourish, Simpkins says team members need intense — almost irritating — curiosity. “I think you have to inspire and promote curiosity in your organization, whether it’s the second-shift test engineer or the project manager,” said Simpkins. “You have to reward curiosity. And then you have to ask questions, which may trigger a new thought or a new path of discovery in the program or project.”
