Planetary and Space Exploration

A summary of U.S. and international space programs, the Earth and its space environment, methods of scientific exploration, spacecraft and payload criteria at the basic physics level, Space Station flight operations and supporting elements, and commercial applications, logistics, maintenance, and servicing design concepts.

Modules

8 Modules, One Sitting Each

Module 1 Available

Earth and Its Space Environment

Earth as the baseline case for "planetary exploration" — atmosphere, magnetosphere, and the near-Earth environment. Basic physics of spacecraft and payload design at a conceptual level.

Start Module →

Module 2 Available

Methods of Scientific Exploration

How missions actually gather data: flybys vs. orbiters vs. landers vs. rovers vs. sample return, and what each method can and can't tell you.

Start Module →

Module 3 Available

The Moon

Apollo through Artemis: what changed in 50 years, current lunar missions, why the Moon matters again strategically and scientifically.

Start Module →

Module 4 Available

Mars

Viking through Perseverance/Curiosity, the sample-return question, human Mars mission proposals, why Mars has a low mission success rate for real technical reasons.

Start Module →

Module 5 Available

The Outer Planets and Small Bodies

Voyager, Galileo, Cassini-Huygens, New Horizons for the outer planets; OSIRIS-REx, Hayabusa/Hayabusa2, and DART for asteroids/comets and planetary defense.

Start Module →

Module 6 Available

Space Station Flight Operations

How a station like the ISS actually runs day to day — supporting elements (life support, power, robotics), planned/future systems, and what "flight operations" means in practice.

Start Module →

Module 7 Available

Commercial Applications, Logistics, and Servicing

Cargo resupply, in-space servicing and maintenance concepts, and how the shift toward commercial logistics is changing who can operate in space and at what cost.

Start Module →

Module 8 Available

Space-Based Astronomy and What's Next

Hubble, JWST, and how orbital telescopes differ from ground-based ones. Closing survey of currently planned and proposed missions across all destinations.

Start Module →

Sourcing

Primary Sources

NASA JPL mission pages (many with public APIs), NASA ISS operations documentation, ESA mission archives, JAXA/CNSA mission pages where available in English.
