🛰️ Space Missions

How does a satellite stay up? Pick a launch speed and see if it crashes, orbits, or escapes into space!

Launch speed: 76%

Aim for the green zone for a stable orbit!

📡 Communication

Rockets like ISRO's PSLV / GSLV are the launch vehicles that carry them up. 🇮🇳

🧠 The Big Idea

A satellite is really falling toward Earth — but it moves sideways so fast that it keeps missing! That balance is a stable orbit.
Too slow → gravity wins → it crashes. Too fast → it beats gravity → it escapes.
The speed needed is the orbital velocity; the speed to break free is the escape velocity (~11.2 km/s for Earth).
