In the summer of 1997,

00:16

NASA's Pathfinder spacecraft landed on the surface of Mars,

00:20

and began transmitting incredible, iconic images back to Earth.

00:25

But several days in, something went terribly wrong.

00:28

The transmissions stopped.

00:30

Pathfinder was, in effect, procrastinating:

00:34

keeping itself fully occupied but failing to do its most important work.

00:39

What was going on?

00:40

There was a bug, it turned out, in its scheduler.

00:44

Every operating system has something called the scheduler

00:48

that tells the CPU how long to work on each task before switching,

00:52

and what to switch to.

00:54

Done right, computers move so fluidly between their various responsibilities,

00:58

they give the illusion of doing everything simultaneously.

01:02

But we all know what happens when things go wrong.

01:06

This should give us, if nothing else, some measure of consolation.
