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.
How long does it take to get to Mars? NASA's New Horizons probe is the fastest spacecraft launched from Earth as of January 2015. It traveled at 36,000 miles per hour when it was launched in 2006. If it had traveled to Mars during the closest approach to Earth, it could have arrived in as little as 39 days.
