Theme- Science, Outer Space
Description:
Engineers Week runs from February 20-26, 2022, and today we are sharing this Planetary Missions design from Studio E Fabrics. This design features aerodynamic forces and calculations related to flying, concentrating on escaping Earth’s gravity and flying in outer space.
The red letter section describes Vertical Ascent and the white letter section describes Vertical Descent. Both of these sections contain calculations to explain ballistic flight, the motion of a flying ball with drag.
The equations surrounding the right triangle describe the Lift to Drag Ratio, the balance of forces on a descending Wright Glider.
The yellow letter section shows the equation for the Law of Gravity, along with the constants for the mass of the Earth, the radius of the Earth, and the universal gravitation constant.
The orange letters under the rocket show the velocity effects on aerodynamic forces. Double the velocity, quadruple the lift and quadruple the drag.
The Solar System graphic shows the shape of the orbits of the planets around the Sun, along with the orbits of some comets and asteroids.
The Earth, Venus, Sun diagram doesn’t have any calculations associated with it. This diagram is often shown when explaining how the Astronomical Unit was first determined. One Astronomical Unit (AU) is the distance from the Earth to the Sun, and it was first calculated using geometry and the transit of Venus.
There is a lot of great science on this pattern. I hope you learned something new today. If you would like more information, visit NASA’s Glenn Research Center to see more detailed explanations of these formulas.
Happy Engineers Week! Science is fun!
