Forty-one years ago today, humans set foot on the moon for the first time. Neil Armstrong left a footprint in the dust, and said, "This is one small step for man, one giant leap for mankind." Interestingly, he went off script for that remark. He meant to say, "This is one small step for a man, one giant leap for mankind." (I think we're all thankful for the flub.)
This post is really about great space photos, but allow me a quick digression into the outsized role Apollo now plays in energy policy, mostly due to that glorious moment four decades ago.
Apollo is the analog of choice for any field in science and technology that proponents think needs a big boost in funding. We apparently need an Apollo project for everything, most especially energy. The impulse to draw the link to Apollo is understandable. NASA was incredibly successful at boosting its budget during the program's early days. And while there was fierce opposition to Apollo (aka "the moondoggle") before its completion, the success of the missions erased most of it.
Energy R&D, particularly for non-nuclear technologies, has historically been underfunded, so most energy experts think it makes sense to increase that budget, perhaps to $15 billion a year (or 0.1% of GDP). By drawing the link with a proud moment in American history, some groups think clean energy advocates can gather political momentum.
But the Apollo analogy just doesn't fit our energy situation, in my mind, not least because we wouldn't want energy R&D to turn out the way Apollo did: the program was canceled before it could finish its docket of flights.
More deeply, Apollo just had to get some guys to the moon. It didn't have to change Earth (though some would argue it did). Put it this way: Apollo barely left a mark on the moon, while a clean energy R&D program would have the goal of changing the way everyone on Earth does everything. So, I lean towards the group of policy people like Butler economist Peter Grossman who think that the rhetoric of Apollo has "political benefits but" ultimately is "detrimental to the adoption of potentially effective energy policies."
In any case, more on that another time. Today, we can just reflect on why Apollo has political cache. It was a wondrous thing getting to the Moon (and beating the Russians to boot!) and NASA savvily made sure it was very well-documented. Enjoy. According to NASA, all these photos were taken exactly 41 years ago on July 20, 1969.
