Why is the U.S. government building a space rocket? In particular, why is it building a space rocket that has cost nearly $20 billion and counting, is years behind schedule, relies on outdated technology, suffers by comparison to private-sector alternatives, and has little justification to begin with?

That’s the question President Joe Biden should bear in mind when pondering the future of the Space Launch System, the two-stage, heavy-lift rocket that aims to bring American astronauts back to the lunar surface and then — someday in the distant, hazy, not-too-specific future — to Mars.
