Spacecraft Radio Off? Yeah, Good Luck Getting Them Back

NASA and basically anyone who loves spacecraft radios are in a bit of a cosmic pickle: once you switch those receivers off, they're uninvited guests at a space party you can't ever re-call. No emergency 'radio on' button—none, zip, nada. Picture a spaceship ghosting you for good. This startling static came from someone presumably very confident in the finality of their transmission decisions. The takeaway? Your spacecraft’s radio has the commitment level of a dramatic breakup: once it's off, it’s off for eternity, which is convenient if you hate unloading emails from Mars rovers but less great if you still want to hear the sweet sound of interplanetary static.
