This expedition is trying to find out if the tallest mountain in the world shrank (January 26, 2017)
This week, India’s surveyor general announced that the government is going to re-measure Mount Everest, in a bid to determine whether the world’s tallest peak shrank (or grew) following a devastating earthquake in 2015.
A team of 30 scientists will use two methods to measure the mountain. The first involves placing a GPS transistor at its summit to measure the distance from sea level; the second involves more traditional on-the-ground triangulation, whereby researchers would determine the distance to the summit based on its angle relative to two baseline points.
