But what if it’s not fine? Even back in 1996, before a single component of the ISS was launched into orbit, NASA foresaw the possibility of an even worse worst-case scenario: an uncontrolled reentry. The crux of this scenario involves multiple systems failing in an improbable but not completely impossible cascade. Cabin depressurization could damage the avionics. The electrical power system could go offline, along with thermal control and data handling. Without these, systems controlling coolant and even propellant could break down. Unmoored, the ISS would edge slowly toward Earth, maybe over a year or two, with no way to control where it is headed or where its debris might land. And no, we could not save ourselves by blowing the station up. This would be extremely dangerous and almost certainly create an enormous amount of space trash—which is how we got into this hypothetical mess in the first place.

Jay Graber became the first CEO of Bluesky in 2021 when the network and its AT Protocol spun out from life as a Twitter research project to go independent, but now she's leaving that role, as reported previously by Wired. While venture capitalist and former Automattic CEO Toni Schneider steps in as interim CEO until a permanent replacement is found, Graber says she will become Bluesky's Chief Innovation Officer, focused on building new things for a platform that has gone from 30 million users about a year ago, to 40 million currently.
