These modules were designed/constructed independent of a specific text book.
-
Range of Planetary Ejecta: For an asteroid impact on Mars, just as on Earth, the range of ejected material depends on the angle and speed at which it is ejected. Disregarding air resistance and assuming a constant value of g, the range is given by the range equation.
-
Varying Gravity With Altitude: For an asteroid impact on Mars, the range of ejected material depends on the angle and speed at which it is ejected. As the projectile increases in altitude however, the value of the gravitational acceleration decreases, which changes the trajectory and increases the range.
-
Global Temperature and Sunspot Activity: In terms of sunspot number, solar activity has been measured since the early 1600's. The average annual temperature on the Earth has also been measured for significant portions of time, and it has been suggested that there is a correlation between the two.
-
Effect Planetary Temperature: The effective temperature of a planet is influenced by its distance from the Sun and its albedo. Planets with higher eccentricities therefore undergo greater changes in their effective temperatures.
-
Tidal Heating of Io: Due to its proximity to Jupiter, Io undergoes tidal heating.
-
Balloon Data on Temperature, Pressure and Alitiude: The pressure and temperature of the atmosphere as it relates to altitude, is most often obtained through balloon launches. On April 30, 2011, a weather balloon was launched from Gila Bend, AZ and gathered data on pressure, temperature, and altitude as the balloon ascended to around 25 km and descended via a parachute.

Fitting Temperature and Pressure Profiles: The pressure and temperature of the atmosphere as it relates to altitude, is most often obtained through balloon launches. On April 30, 2011, a weather balloon was launched from Gila Bend, AZ and gathered data on pressure, temperature, and altitude as the balloon ascended to around 25 km and descended via a parachute. The temperature, pressure, and density can be modeled as functions of altitude.
