Re-measuring Mount Everest

摘要

The world's highest mountain might just be a little higher than traditionally thought: new measurements to determine the Earth's geoid could add a few metres to Mount Everest's height. In December 2010, scientists on board a King Air turboprop ascended through the thin Himalayan air to find out how high Mount Everest really is. By flying back and forth over Mount Everest, the team sought to measure the gravitational pull at the peak using a gravimeter. Results are expected to be ready in summer 2012.
