Risk And Exploration Go Hand In Hand

Blood and Money, Wayne Hale

"We must have a clear-eyed appreciation for the risk involved in space exploration. Flying to the moon will not be much safer in 2024 than it was in 1969. Exploration always comes with risk, and with some regularity exploration risk is realized. The real cost of Artemis will be written in blood. Face that fact. This may be considered a poor time to bring this up - at a time when so many folks are actively working toward program approval. Death is hardly a selling point. But if we don't recognize that fact, the program will come apart at the first bad day."

Administrators Symposium on Risk and Exploration: Earth, Sea and the Stars, NASA (2004)

"Challenge fosters excellence, often drawing on previously untapped skills and abilities. Each of us takes and accepts risk as a part of our daily existence. We often go out of our way to seek challenge. However, seeking challenge often means accepting a high level of risk. The dictionary defi nes risk as being exposed to hazard or danger. To accept risk is to accept possible loss or injury, even death. One of the key issues that continues to be debated in the tragedy of the Space Shuttle Columbia is the level of risk NASA accepted. And, ultimately, the entire nation is now engaged in a broader debate over whether or not the exploration of space is worth the risk of human life. While risk can often be reduced or controlled, there comes a point when the removal of all risk is either impossible or so impractical that it completely undermines the very nature of what NASA was created to do--to pioneer the future. Everyone today understands that human space exploration is a risky endeavor. However, the quest for discovery and knowledge, and the risks involved in overcoming seemingly insurmountable obstacles is not unique to NASA. Whether the challenge is exploring the depths of our oceans or reaching the top of our highest mountains, great feats usually involve great risk."

Fortuna Audaces Juvat, @JimBridenstine, earlier post

"During that time when the VSE was seen as a refreshing recommitment to exploration post-Columbia - there was a momentary alliance between all factions. People thought bold adventurous thoughts again. Back to the Moon and then on to Mars. Craig Steidle was looking to do some branding and meme generation. He hit on one thing that was really ballsy (larger image) . The motto was "Fortuna Audaces Juvat" which is usually translated as a variant of "Fortune favors the bold" - a latin proverb most prominently repeated in Virgil's "Aeneid" at 10.284. You have no doubt seen this phrase before. Its common in the military - for good reasons. It has a Star Trek vibe to it. Craig Steidel drew a line in the sand and provided a motto to wear on one's shoulders as the agency set forth back into space. I thought it was a master stroke. Too bad NASA doesn't do things like this any more."

Keith's note: Wayne Hale's words ring true in a way we seem to be forgetting again. In 2004 John Grunsfeld and I organized a symposium on Risk and Exploration for Sean O'Keefe. At the core of this event was an attempt to compare risks faced - and accepted by NASA and those faced and accepted by other explorers. We held this event barely a year after the loss of Columbia - so these risk evaluations were foremost in everyone's minds. This event had a big effect on people's thinking - including Wayne Hale who ordered a box of copies of the Symposium's proceedings to use to educate his staff at JSC. So now here we are in 2019. We've had several accidents or "mishaps" as we develop commercial crew flights while flying on Soyuz spacecraft. NASA is now talking about skipping a "green test" - and all-up firing of the SLS first stage so that we can meet a rushed deadline - one set with little warning - to land humans on the Moon in 5 years.

Yes fortune does often favor the bold. But it also punishes the ill-prepared.
