Curiosity Comes Cheap - Why the latest Mars rover (and all planetary exploration) is a steal
It’s happening again, sure as clockwork. Unable to tear themselves away from the lazy narratives that the media hold on to like so many safety blankets, the usual tropes about MSL Curiosity’s cost are popping up in almost every news story or interview about the mission.
Here’s a good example. Here, Adam Steltzner (Curiosity EDL Lead Engineer) is being interviewed by Shepard Smith on Fox News. Note that this is the morning after he and his team’s greatest professional achievement in their collective lives. Pay special attention to the attitude of the questioner:
It’s not enough that the landing was a complete success. It’s not enough that JPL and NASA have gone almost 15 years without a major robotic mission failure. No, it always comes back to the tired questions of “can we afford this?” and “why should we pay for it?”
Here, the media, let me answer these questions for you. I’ll save you the trouble of having to ask them again:
2) To develop advanced technology and push the limits of engineering capability, to question our place in the cosmos, and to pursue the eternal desire of exploration unique to our species.
There. That wasn’t too hard, was it? And let me add the additional note, which is something that we all must keep in mind. This is the sad irony of this entire narrative:
The Curiosity mission was cheap. In fact, our entire planetary exploration program costs almost nothing.
Let me explain, because I’m sure that the number 2.5 billion is popping into your head right now (see how insidious the narrative is?).
Curiosity had a total cost of 2.5 billion dollars, yes, but it’s not like NASA went over to the Rover Depot, plucked the glamor model off the shelf and whipped out Uncle Sam’s credit card.
No, NASA spread the cost of this mission out over eight years. The money spent went into salaries of highly-skilled engineers, programmers, managers, and independent contractors in over twenty states across the country. Things like the cost of rocket to launch it to Mars are included in that total, too, which accounts for nearly a fifth of the amount.
If you you just divide the total cost by the number of years NASA has saved for it, you come out with about $312 million per year. This works about to approximately 1.8% of NASA’s yearly budget and approximately diddly-squat of the total federal budget. That’s about $1 per year for every American, aka, nothing. Think of it this way: say you lose one dime every month this year. Whoops! You’ve lost more money than you spent on Curiosity.
For this tiny amount of money, we’ve developed some of the most advanced machinery ever created. We advance our scientific understanding of the universe. We encourage the development of highly-educated problem solvers and provide some of them with jobs. We’ll make discoveries and raise new questions that no one could have previously dreamed of.
A larger topic that I’ll discuss in a separate post is our whole Planetary Exploration budget, which is a division inside of NASA responsible for every robotic mission to the planets. And I really mean every mission: New Horizons, Juno, Voyager, Cassini, MER Opportunity, Curiosity, Mars Reconnaissance Orbiter, Mars Odyssey, and the rest. All of those are funded out of the pool of money reserved for planetary exploration, which is filled to the tune of about $1.5 billion a year. That’s really it. Americans spend more on dog toys every year than the cost to run all of these missions. Just think about that the next time someone in the media asks the question, “can we afford this?”
That’s the crux of this sorry joke. Not only can we afford it, we can afford to spend a lot more. Instead, we choose not to explore. We choose not to know what’s out there. We choose to pretend that Curiosity is some budget-busting mission when really it’s one of the best deals we get from our tax dollars.
We need to change the narrative. The next time someone you know comments about the cost of Curiosity or any other NASA mission, respond with, “Yeah, I know! It’s so cheap! It’s amazing how much they can achieve despite their funding.”
Finally, if you are a scientist and you face this type of question, don’t answer defensively! A defensive answer serves only to legitimize the argument. A respectful answer that denies the validity of the question is the most important way to respond.
Slowly, we can change the question from “why so much?” to “why so little?”

We know you love reading about space exploration, but did you know you can make it happen?
