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.
For a more detailed discussion, see the. How long does it take? It takes the Earth one year to orbit the Sun and it takes Mars about 1.9 years (say 2 years for easy calculation) to orbit the Sun. The elliptical orbit which carries you from Earth to Mars is longer than Earth's orbit, but shorter than Mars' orbit.ll in all, your trip to Mars would take about 21 months: 9 months to get there, 3 months there, and 9 months to get back. With our current rocket technology, there is no way around this.
