A team of 20 dedicated scientists, students, engineers and science enthusiasts from all over the world travel to Santiago, Chile
Collectively they travel north to Vicuña, where it is predicted that the totality line of the eclipse shall pass
They set up their equipment - both the modern telescopes and the historical equipment - and practice using it (Total solar eclipses don't come around very often so you want to make sure everything is ready to go)
Totality (the point at which the moon completely blocks out the sun) is predicted to be reached on Tuesday 2nd July 20:38:16 GMT. The team will have effectively 2.25 minutes to obtain all of the requisite data.
The team shall now analyse the obtained results, comparing between the modern and the historical equipment, to determine if Einstein's Theory of Relativity holds true.
