A LITTLE CURIOSITY. A LOT OF SPACE.
Make sense
of spaceflight.
Explore the ideas that take us beyond Earth. One experiment, one question, one discovery at a time.
Eight tools, one course
FORCE TO ORBIT
SORT BY
01 / MOTION AND FORCES
Motion Lab
Force, mass and momentum move a cargo truck on a straight road.
Open tool02 / ROCKET PROPULSION
Thrust Lab
Mass flow and exhaust velocity produce the force that moves a rocket.
Open tool03 / STAGING
Staging Lab
Drop empty hardware. Improve upper-stage exhaust velocity.
Open tool04 / ORBITAL MOTION
Orbit & Escape
How fast must you move sideways to keep missing Earth?
Open tool05 / ORBITAL MECHANICS
Kepler Explorer
Change eccentricity and watch orbit shape, speed, and period respond together.
Open tool06 / ORBITAL MANEUVERS
Transfer Lab
Burn, coast, burn again — move between orbits and out to Mars.
Open tool07 / ORBITAL MECHANICS · CAPSTONE
Orbit3D
Discover how an orbit's size, shape, and tilt change the journey around Earth.
Open tool08 / ELECTRIC PROPULSION · OPTIONAL BONUS
Electric Propulsion Lab
Hall thrusters, the OneWeb constellation, and an optional station-keeping game.
