Objectives
- Understand why orbiting is just continuous free fall and why astronauts feel weightless
- Apply Kepler's three laws to predict orbital shapes, speeds, and periods
- Identify and compare orbit types including geostationary, polar, sun-synchronous, and Molniya
- Reason about delta-v budgets and why every maneuver in space has a propellant cost
- Explain Hohmann transfers, gravity assists, plane changes, rendezvous, and aerobraking
- Recognize how perturbations like drag, J2 oblateness, and third-body effects reshape orbits
- Understand launch windows, equatorial launch advantages, and why staging is essential
- Describe Lagrange points and why missions like James Webb park there
Pre Requisites
- Basic high school physics concepts like force, mass, and velocity are helpful
- Comfort with the idea of gravity as an attractive force between masses
- Curiosity about spaceflight, satellites, or astronomy
- No calculus, differential equations, or programming experience required
- An open mind willing to embrace counterintuitive ideas about motion in space
FAQ
- Q. How long do I have access to the course materials?
- A. You can view and review the lecture materials indefinitely, like an on-demand channel.
- Q. Can I take my courses with me wherever I go?
- A. Definitely! If you have an internet connection, courses on Udemy are available on any device at any time. If you don't have an internet connection, some instructors also let their students download course lectures. That's up to the instructor though, so make sure you get on their good side!
