A startup is ten days from launching a satellite rescue mission that could save a $500M observatory — plus JWST finds salt clouds on a distant world and SETI researchers discover why alien signals may have gone undetected. Today's biggest stories in space and astronomy, clear and concise.

A startup built a satellite-servicing spacecraft in ten months, shipped it to the launch pad, and is now ten days out from a mission that could save a five-hundred-million-dollar observatory from burning up in Earth's atmosphere. That's the signal this week.
The company that stepped in is Katalyst Space Technologies. Their spacecraft, called Link, completed all testing and has shipped to the launch pad ahead of a June twenty-seventh liftoff.
The Swift rescue doesn't exist in isolation. It fits a broader shift in how space infrastructure gets built and maintained.
Away from the infrastructure story, JWST delivered another atmospheric first. The telescope detected salt clouds in the atmosphere of GJ504b, a cold planetary-mass object fifty-seven light-years away sometimes called the Pink Planet.
Two other findings this cycle both point at the same underlying problem: detection limits shape what we think we know. Stanford's new STEHM model predicts that rocky exoplanets at least eighty percent the size of Earth can retain atmospheres for more than ten billion years, narrowing which worlds are worth targeting for biosignature searches.
Before we close, a low-risk but notable event: a plane-sized asteroid designated two thousand three LN six makes a close pass tomorrow at eight hundred eighty thousand miles, moving at nearly nine thousand miles per hour. No impact risk.
