This is the thing the last song was about, LightSail, which even now is orbiting Earth and probably (if it’s going as expected) accelerating. We’re not entirely sure how it’s going, though, because the software has run into a little problem.
Right now, they’re hoping a cosmic ray will reboot the onboard computer, which is apparently a thing that happens once you’re outside the atmosphere.
Oh, and as I’m typing this on Saturday night, it looks like that might have just happened! Huh.
Now we’ll get to see if this thing works after all!
