- Look, there's the comet!

- Wow, there it goes!

There it goes!

- Oh, no!

The comet disappeared!

How will I find it?

- Alpha Pig to the rescue!

With my space map, I can help find the comet!

[Beeping] [Galileo gasps] - The rocket computer tells me that the comet is headed for Mars!

- Got it, Galileo.

We need to find Mars.

"Mars"begins with an "M".

Where's the letter "M"?

- [Kids]: There!

- There's the "M"!

On the planet Mars.

Ooh, it's that red one!

- Blast off for M-M-M-Mars!

- Weeeeeee!

- Woo-hoooo!

There's Mars!

it's the dusty red one, just like on the map.

- The comet!

There it is!

And... there it goes.

[Beeping] - Super Readers, the rocket computer says that the comet is headed for Jupiter.

- OK, then.

We've got to go to Jupiter too.

"Jupiter"begins with the letter "J".

Um... where's the "J"?

- [Kids]: There!

- There's the "J"!

On the huuuuge planet Jupiter!

- Blast off for... Jupiter!

- [Super Readers]: Weeeeeee!

- Whoa!

- Wow!

Jupiter is one big planet!

- It's the biggest planet of them all!

- Meow!

- The comet!

There it is!

[Super Why gasps] [Pig sighs] And there it goes.

[Beeping] - Alert!

The rocket computer says that the comet is headed for Neptune.

- "Neptune"begins with an "N".

Which word starts with the letter "N"?

- [Kids]: There!

- There's the "N"!

On that windy-looking blue planet.

- Blast off for Neptune!

- Weeeeeeee!

- Woo-hoo!

- And look!

There's the comet!

- Meow!

- And my little kitty-kins!

Houston!

We found him!

- Meow!

- OK, you crazy comet, don't move!

We're coming to get Houston.

Woof, woof, woof!

- Hee-hee-hee-hee!

- Lickety letters!

We followed the space map and found the comet!
