Giant truck set for sky-high task

A colossal 28-wheel truck that will help build a major telescope array in the Chilean Andes has successfully passed a series of tests.
The giant vehicle will heave antennas - each weighing 115 tonnes - up a mountainside to the site of the array, a plateau 5,000m above sea level.
The Alma telescope will study the night sky at sub-millimetre wavelengths.
Astronomers say Alma will illuminate one half of the Universe that has hitherto been shrouded in darkness.
