Sls Sustainability: The Debate Over Nasa’s Expendable Rocket
Alright, space fans, let's talk rockets! Specifically, let's chat about NASA's big, shiny, and dare I say, expensive, Space Launch System, or as it’s more commonly known, the SLS. Now, before you start blasting off into the comments section, hear me out. I’ve got a bit of an… unconventional take on this whole thing. Think of me as the slightly chaotic but well-meaning cousin at the family reunion, the one who says the thing everyone’s thinking but nobody’s brave enough to admit.
We all love space, right? We want to explore, go to the Moon again, maybe even Mars someday. And for that, we need rockets. Big, powerful rockets. And the SLS? Oh, it’s definitely big and powerful. It’s like the absolute unit of rocketery. It’s the rocket that shows up to the party and immediately starts lifting the heaviest weights. It’s got a certain… presence. It’s got all the bells and whistles, all the cutting-edge tech that NASA can throw at it.
But here’s where my little contrarian heart starts to flutter. Sustainability. The word itself sounds so… earnest. So eco-conscious. We’re talking about rockets that we basically use once and then… poof! Gone. Like a really, really fancy firework that costs more than your house. And I’m looking at the SLS, this magnificent beast that takes years and billions of dollars to build, and I’m thinking, “Is this the most sustainable way to get to orbit?”
Now, I know what the eggheads will say. They’ll talk about the unparalleled power, the ability to lift huge payloads for deep space missions. They'll mention the Artemis program and the glorious return to the Moon. And yes, absolutely. The SLS is designed for some seriously ambitious stuff. It’s the chariot to carry us to new frontiers. It's the ultimate Uber Black for astronauts.
But let’s be real. It’s also… expendable. Like a disposable coffee cup, but with significantly more thrust and a few stages that are, shall we say, robustly jettisoned. And every time one of these behemoths lights up the sky, it leaves behind a trail of… well, stuff. Stuff that isn’t exactly biodegradable. And then we build another one. And another. And the bill? Let’s just say it’s enough to make your wallet weep.
Think about it this way. Imagine you’re going on a road trip, a really epic one. Do you buy a brand-new, custom-built, super-duper car for every single trip, use it once, and then just… abandon it by the side of the road when you reach your destination? No! You’d probably get a reliable car, maybe a slightly used one, and then you’d keep it, maintain it, and use it for lots of trips. You'd get your money's worth.
And that's where my little spark of heresy ignites. What about reusable rockets? I mean, we’ve seen them, right? They land themselves, all suave and composed, like a sophisticated gentleman returning home after a night out. They’re the rocket equivalent of a fancy reusable water bottle. You fill it up, you use it, you refill it. Simple. Elegant. And, dare I say, smarter from a long-term perspective.
Companies like SpaceX have really shown us the way. Their Falcon 9 rockets? They’re like the reliable, workhorse sedans of the space industry. They’re getting the job done, they’re doing it repeatedly, and they’re doing it without leaving a permanent ecological footprint the size of Texas. They’re the friends who always show up on time, bringing snacks and helping you move furniture. Dependable.
So, the SLS is like the extravagant, one-off sports car. It’s impressive, it’s powerful, it’s a marvel of engineering. It’s the kind of thing you’d rent for a special occasion, and then happily hand the keys back. But for the day-to-day grind of getting stuff into space, for the sheer volume of launches we’re starting to see, it feels a bit… overkill. And perhaps a little… wasteful?
Is the SLS the space equivalent of a solid gold toilet? Beautiful, luxurious, but perhaps not the most practical choice for everyday plumbing?

I’m not saying we should ditch the SLS entirely. For those truly massive, once-in-a-generation missions, maybe it has its place. It’s like having a really fancy, rarely used blender that can pulverize granite. You don’t use it for your morning smoothie, but when you need to make a truly epic batch of margaritas for a huge party, it’s your go-to.
But for everything else? For the frequent trips to the International Space Station, for the satellite deployments, for the general hustle and bustle of getting us into orbit? It feels like we’re using a sledgehammer to crack a nut. And that sledgehammer costs a whole lot of taxpayer money to build and then, poof, it’s gone.
My humble, slightly unpopular opinion? While the SLS is a testament to human ingenuity and our boundless ambition, maybe it’s time to lean more heavily into the reusable revolution. Let’s get our fill of the majestic, albeit fleeting, spectacle of the SLS launching, and then let’s put our resources into building and perfecting rockets that can fly again and again. Rockets that are as kind to our planet as they are powerful in reaching for the stars. Because, you know, we only have one Earth to launch from.
