##### Orbits: Kepler's Laws

In this educational aid we are going to talk about Kepler's Laws of planetary motion. For 400 years these laws have been the foundation to understanding orbits. Not just for the planets orbiting the Sun, but also satellites orbiting the Earth.

##### Orbits: Newton's Laws

In this educational aid we are going to talk about Newton's three laws of motion and how they affect orbits. Newton developed his theory on gravitation when he was 23 years old and published his laws of motion 20 years later in 1687.

##### Orbits: Gravity

In this educational aid we are going to discuss gravity and how it enables orbits and the relationship between distance and the force of gravity.

##### Orbits: Conservation of Energy & Momentum

In this educational aid we are going to talk about conservation of energy and conservation of momentum, and how each affecs orbits.

##### Orbits: Classical Orbital Elements (COEs)

In this educational aid we will discuss the Classical Orbital Elements or COEs. The COEs give us a practical way of understanding the characteristics of as orbit and a satellite's location at any given time.

##### Orbits: Orbit Types

In this educational aid you'll learn about common orbit types and an orbtial perturbation that allows for specific orbits. We will discuss four different types: Low Earth Orbit (LEO), Medium Earth Orbit (MEO), Geosynchronous Earth Orbit (GEO), and two special orbits: Sun-synchronous and Molniya.

##### Orbits: 2-Body Equation of Motion

In this educational aid we are going to talk about the 2-body equation of motion. The 2-body equation of motion is an equation that allows us to relate the motion of an object or body or satellite, around another object or body such as the Earth.

##### Electromagnetic Spectrum Basics

In this educational aid you'll learn the basics of the Electromagnetic Spectrum. Specifically, its make-up, space application, frequency, and wavelength. So what is the Electromagnetic spectrum? Most simply it is light and describes the total range of light that exists.

##### Spacecraft Subsystems

In this educational aid we are going to cover spacecraft subsystems. The spacecraft can be divided into two major part, the payload and the bus. The payload is what does the mission, its why we are going into space. And the bus, is all the parts that support the mission.

##### Space Environment

In this educational aid we'll cover the space environment and its effect on spacecraft. The space environment can be grouped into six categories: Vacuum, Neutral, Plasma, Radiation, Micrometeoroid/Orbital Debris, and Scintillation.

##### Space Mission Operations

Have you ever wondered how space systems are optimized to maximize mission accomplishment? In this educational aid, we'll discuss Space Mission Operations. Space Mission Operations is how we use all or part of a space system to achieve goals.

##### Launch, Propulsion, and Re-entry

In this educational aid we'll identify key terminology needed to better understand propulsion, going into detail on launch constraints and phases, and identify the propulsion systems used for launches, spacecraft maneuvering, and re-entry.
