What happens when the sun blocks our signal?

About every two years, Earth and Mars wind up on opposite sides of the sun.

It's like being on either side of a huge bonfire:

we can't see Mars, and our landers, rovers, and orbiters can't see us.

If our spacecraft send back signals, charged particles from the sun could interfere,

That's not a big deal: if something's missing, it can always be resent later.

But, no way do we want to lose data when we send up commands.

Receiving a partial command could confuse the spacecraft, putting them in grave danger!

So, mission controllers plan ahead by sending up simple to-do lists, including regular health check-ups.

Back home, this break in communications lets team members catch up on other work...

Solar conjunction lasts just a few weeks.

Then it's back to the grindstone... on Earth and on Mars.
