NASA overhauls Artemis program, delaying Moon landing to 2028

As far as WIRED can tell, no one has ever died because a piece of space station hit them. Some pieces of Skylab did fall on a remote part of Western Australia, and Jimmy Carter formally apologized, but no one was hurt. The odds of a piece hitting a populated area are low. Most of the world is ocean, and most land is uninhabited. In 2024, a piece of space trash that was ejected from the ISS survived atmospheric burn-up, fell through the sky, and crashed through the roof of a home belonging to a very real, and rightfully perturbed, Florida man. He tweeted about it and then sued NASA, but he wasn’t injured.

But after years of building on Web streams – implementing them in both Node.js and Cloudflare Workers, debugging production issues for customers and runtimes, and helping developers work through far too many common pitfalls – I've come to believe that the standard API has fundamental usability and performance issues that cannot be fixed easily with incremental improvements alone. The problems aren't bugs; they're consequences of design decisions that may have made sense a decade ago, but don't align with how JavaScript developers write code today.

Finding these optimization opportunities can itself be a significant undertaking. It requires end-to-end understanding of the spec to identify which behaviors are observable and which can safely be elided. Even then, whether a given optimization is actually spec-compliant is often unclear. Implementers must make judgment calls about which semantics they can relax without breaking compatibility. This puts enormous pressure on runtime teams to become spec experts just to achieve acceptable performance.
