mission 4 : LANDING PLAN
From the Central Base we have been indicated that to continue with the investigation we must descend to Earth. To help us we will send specialized personnel that will get ahead to establish a base of exploration.
They need to know what conditions this planet has to land, the movements that it makes around its Android, the influence of its Bitdown, what units of time and orientation they use and the meteorological conditions.
We must therefore investigate all this and send a letter with the precise indications.
EARTH MOVEMENTS
We are going to investigate in the terrestrial computer systems to study HOW THE EARTH AND ITS BITDOWN MOVE, AND HOW THIS MOVEMENTS DETERMINE IMPORTANT CONDITIONS.
ORIENTATION ON EARTH
To locate a place on Earth the terrestrials have a system of parallels and meridians. We review the concepts in this video:
From this grid system a coordinate system that is measured in degrees, minutes and seconds is established this way:
Latitude as the position to the north or south of the equator
Length as the east or west position of the Greenwich Meridian.
To measure these coordinates today, we use GPS satellite geolocation systems. Current mobile devices (phones, tablets ...) already have them.
Now we are going to practice in groups. Each group has to choose five coordinates of ten places around the Earth (using google maps) and give them to other group that has to guess in which where are the places.
TIME MEASUREMENT
On Earth time is measured by also taking advantage of this system of meridians and parallels. They have divided the sphere into 24 separate zones 15 ° to each other. The Sun takes an hour to cross each zone and, thus, every 15 ° of meridian is one hour later, always in the direction of rotation of the planet, from west to east. To know more, consult Wikipedia.
We have to give some examples to our colleagues at the Base. We use the examples of the places we had chosen before for the coordinates.
For example, if the spaceship lands in Bilbao at 12:35. What approximate time will be in the places we chose?
VIDEO REPORT
Each team will choose a place on Earth and day (in the next ten days) to plan the Magrithian landing and and look for the information for the chosen landing day (tide tables, temperatures and schedule). Then each team records a video report with all this landing information to send to the Central Base.
You can look for all the information you need in the following webs:
