The author proposes extensions to the Scrum process model to add formal requirements and test case management, with requirements and test case work items that have their own state transition (e.g. âNot Implementedâ, âPartially Implementedâ, âFully Implementedâ).
In order to calculate the time of travel with this speed from Earth to Mars, we need to know the distance. When the Mars and the Earth are at the opposite sides of the Sun, the distance is the largest: approximately: 378 million km. The time needed for an electromagnetic wave to cover this distance is approximately: 21 minute. The closest distance between Mars and Earth is 78 million km, the time in this case is: 4.3 min.
The time it would take such a probe to get to Mars would be: 1  Closest approach: 942 hours (39 days) 2  Farthest approach: 6,944 hours (289 days) 3  On average: 3,888 hours (162 days)
