Per Ardua Ad Astra

This is a repost of what I wrote last year during this difficult week for NASA. But I stand by every word, and it is just as important now as it was then, and, I think, will continue to be.

Today marks the second in a week of three tragic anniversaries in space exploration. On Jan. 27, 1967, we lost three astronauts in the Apollo 1 fire. On Feb. 1, 2003, seven astronauts died when Columbia broke apart upon re-entering Earthâs atmosphere. And Jan. 28, 1986, is when the Space Shuttle Challenger exploded, killing all seven astronauts on board.

All three of these events were horrible. All three were the results of unlikely chains of events that seemed inevitable afterward. All three sparked immense debate over the dangers and value of exploring space.

And all three should show us how important it is that we carry on that exploration.

There are two ways to look at why slipping loose the surly bonds of Earth is so critical. One is practical. Going into space has given us tremendous advantages in life. Global communication. Weather forecasting. Technology spinoffs that have generated vast economies. The list goes on and on. How many dangerous regimes have collapsed because we can directly see and talk to those being oppressed? How many lives have been saved by advance knowledge of crippling weather events? How much have our lives improved due to the wonderful technology generated? The money spent on space exploration has literally paid us back manifold.

That argument alone is more than enough to support both automated and crewed space exploration. But thereâs more.

We are a species of explorers. Itâs in our blood, in our makeup. We crave to see whatâs around the next corner, whatâs over that hill, whatâs next in our adventure. Sometimes we learn something massively important, and sometimes we donât. Sometimes we come home to tell the tale, and sometimes we donât. Exploration has fantastic rewards, and grave dangers. But fulfilling our need to explore is its own goal.

The practical benefits of exploration are our sustenance, but the adventure itself is the flavor. The price we pay for this, sometimes, is counted in human lives. And itâs a terrible price. But we must continue to explore because itâs a part of us.

The very fact that so many people are so deeply affected by these events shows just how profoundly space exploration reaches into us. Any event involving large multiple deaths in a single, searing moment is going to resonate with us, and certainly watching it live on television will magnify that feeling. But in this case, we hold astronauts to a higher level. Like with any dangerous occupation that makes life better for others, risking their lives is part of the job requirement.

At first, it feels like this makes these losses cut even more. But itâs ironic: The astronauts themselves knew the risks and downplayed the significance of them potentially being killed. They thought it was worth the risk, or else they wouldnât have done what they did. That doesnât make their loss any easier, but it shows us that we must carry onâwho could convey that message better than the ones who themselves sit on top of those rockets?

There are many reasons we lose lives exploring space. Itâs inherently difficult and dangerous, a hostile environment that takes supreme and envelope-pushing effort even to reach. And there will always be human errors, those caused by carelessness, rush, politics, greed, and simple mistakes. We can minimize these risks in many ways, but over time, the odds of these mistakes leading to tragedy become inevitable.

The only way to absolutely minimize these risks is to stop exploring. And thatâs unacceptable. Ships are safe in the harbor, but thatâs not what ships are for.

So, for Grissom, Chaffee, and White; for Scobee, Smith, McAuliffe, Onizuka, Resnick, McNair, and Jarvis; for Brown, Husband, Clark, Chawla, Anderson, McCool, and Ramon, and for all the others who gave their lives for this great adventure:

I hope that we have learned from your experience, I hope that we have become better through your experience, and that, while we will never forget what happened to you, we will also remember what you were trying to do, and what you did do.

Per ardua ad astra.
