Learn how the ISS generates, stores, manages, and distributes electricity in orbit, including solar arrays, batteries, and power control systems.

Learn what escape velocity means, why it matters in spaceflight, and how gravity, mass, and distance shape the speed needed to leave a body’s pull.

Learn why rockets launch vertically, how gravity turn maneuvers work, and why straight-up liftoff is usually the most efficient start.

Learn how booster landing works, from reentry control and engine relight to grid fins, landing legs, and precision touchdown.

Learn how astronauts travel to the International Space Station, from launch and orbital rendezvous to docking and arrival aboard the ISS.

Learn how spacecraft docking works, from orbital rendezvous and alignment to sensors, latches, and pressurized transfer between vehicles.

Spacecraft rely on computers for navigation, timing, autonomy, and fault protection. Here is how onboard systems make modern space missions possible.
