Understanding microgravity
- Gravity is a force that governs motion through the universe
- People mistakenly think there is no gravity above the Earth's atmosphere
- Typical orbital altitudes for spaceflight = 120-360 miles
- Gravitational field is still quite strong
- Earth's gravitational field at 250 miles is 88.8% of its strength at the surface
- Orbiting spacecraft are kept in orbit around the Earth by gravity
