For the first time, a fully stacked Space Launch System rocket and Orion spacecraft rolled out of the Vehicle Assembly Building at Kennedy Space Center on Thursday evening. [credit: Trevor Mahlmann ]
On Friday morning, NASA's titanic Space Launch System reached the launch pad. The rocket is not yet ready to fly, and it may not lift off the planet for several more months. But as the fully assembled, skyscraper-sized rocket rolled into a serene Florida evening on Thursday at Kennedy Space Center, no one could deny that it is finally here.
Frankly, it is hard to know how to feel about this rocket. Certainly, one cannot help but be awed by a rocket that is as tall as a US football field is long. Designing, building, and testing such a large and complex machine represents a significant engineering achievement. But it's impossible to have a rational discussion about the Space Launch System rocket and its payload, the Orion spacecraft, without considering its enormous expense, ongoing delays, and looming obsolescence.
One thing seems clear: although this fully stacked SLS rocket and Orion crew capsule have set the stage for the uncrewed Artemis I test launch later this year, the rollout does not mark the end of the beginning for this launch system. Rather, it's the beginning of the end. This is probably the last gasp of the Apollo era of NASA that has gripped the space agency for six decades.
