So you're using a balloon to carry something that is two tons all the way to an altitude of 40 km. And the engineers, the technicians, the physicists have all got to assemble on the Ross Ice Shelf, because Antarctica, I won't go into the reasons why, but it's one of the most favorable places for doing these balloon launches, except for the weather.
O sea, se usa un globo para llevar algo que pesa 2 toneladas hasta una altitud de 40 km. Los ingenieros, los técnicos, los físicos, han tenido que montar todo sobre la barrera de Ross porque la Antártida es uno de los mejores lugares para lanzar este tipo de globos, salvo por el clima.
