NASA's SLS rocket system might be the most powerful ever created, but it's also extremely unsustainable. Here's why.
. Adding all of those costs on, plus the addition of changing prices over the coming years, and we’re looking at some very expensive missions.The SLS rocket also utilizes the same propellant that NASA used back in the Space Shuttle era, which means a constant concern of leaks and having to refill tanks to get them back up to where they need to be for launch. It’s all of these concerns that have many wondering just how long NASA’s SLS will last as its primary driver for missions like this.
