INTERACTIVE EXPERIENCE
The art of falling
Launch a probe. Change its speed. Watch a circle become an ellipse, or give it enough energy to escape.

Space &
Gravity
A falling stone and an orbiting world have more in common than you might think.
Explore motion under gravity, from a sideways launch to in-flight engine burns and a planetary flyby. Follow the Moon through its phases and eclipses, then discover repeating orbits and sensitive futures in the three-body problem.

NEW INTERACTIVE EXPERIENCE
Eclipse Lab
Explore lunar and solar eclipses through large shadow diagrams, a moving tilted orbit, a close-up Moon and the red light bent through Earth’s atmosphere.
Enter the experiment
GRAVITY ASSIST
A little help from a world.
Fly past a moving planet. Borrow a little of its orbital energy, or give some back. Change your point of view to see how the same encounter tells two stories.
Enter the experiment
MOON PHASES
Same Moon. Changing light.
Move the Moon around Earth and watch its face change. Connect crescents and quarters to the Sun, discover when to look up, and explore why a lunar month has two different lengths.
Enter the experiment
ORBIT MANOEUVRES
One burn. A different orbit.
Fire an engine while you fly. Preview the new path, coast to its far end, and discover why reaching a higher circular orbit can take two forward burns.
Enter the experiment
THREE BODIES, ONE LAW
The Three-Body Problem
One law of gravity. A repeating dance, a close encounter, or two futures that slowly part ways. Change a tiny detail and discover how much it can matter.
Enter the experimentIdeas you’ll explore
Gravity
An attraction that changes the direction and speed of a moving body.
Orbits
Explore the balance between inward acceleration and sideways motion.
Energy
Investigate what separates a bound path from an escape trajectory.
