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.
Unmanned probes from Earth can take from 7 months to two years to reach Mars, depending on when they are launched and how fast they can travel. The direct distance can vary frâ¦om about 58 million kilometers to more than 400 million kilometers. The distance is at least 36 million miles (58 million km).
