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.
The first part of Bridgerton's fourth season left us on cliffhanger worthy of throwing glassware, with three little words hanging in the air: "Be my mistress." And they'll stay there, stitched into the hem of Part 2, which continues the season's trials, trysts, and tribulations, and moves into more serious territory (don't worry, it's still Bridgerton, not Hamnet).。业内人士推荐同城约会作为进阶阅读
