Ballistics

We just learned about the Inertial Navigation Systems.

Another part of navigating rockets is the science of Ballistics.

This is all about the forces that are moving the rocket around, and what happens to the rocket because of those forces.

Usually there are 4 forces on the rocket:
1. Thrust from the engine
2. Gravity
3. Drag - which is like the air blowing against the rocket
4. Lift - which is like air blowing with the rocket

Opalescent Inshore Squid

We just learned about the Big Blue Octopus.

Another type of cephalopod is the Opalescent Inshore Squid, also called Doryteuthis opalescens.

This is a very small squid, only growing to about 7 inches.

They live in the Pacific ocean by the eastern short of North America, all the way from Alaska to Mexico.

These squids are tiny but there are lots and lots of them.
The mother squids lay their eggs on the ocean floor, and there are so many that they cover acres and acres in the sand.
Because there are so many eggs there, a lot of ocean predators like starfish will go eat the eggs.

When the squids grow up, they are still very tiny but when they get together in groups there can be millions of them all in one place!
With so many of them swimming around, they are a big snack for other animals like sharks and seals.
