00:00The Probe 3 space mission by the European Space Agency

00:03comprises two satellites which must fly in a precise formation

00:07to observe the mysterious solar corona. The solar corona is the exterior layer

00:12of the Sun's atmosphere.

00:13It is a cloud extending over millions of kilometers

00:16and is the origin of the solar wind. During eclipses we can see,

00:20with the naked eye, its luminous halo which overlaps the edge of the Moon,

00:24but for the rest of the time it is hidden by the light of the Sun and is

00:28difficult to observe.

00:29Observation of the corona didn't start until the 20th century

00:33with the invention of the coronagraph, a telescope which has the equivalent of a

00:37lunar disk

00:38to simulate the conditions of an eclipse. Probe 3 will use this technology

00:43by creating for the first time a giant coronagraph.

00:46Two satellites will fly in tandem in a high Earth

00:49orbit. The first will block out the Sun, like the Moon during an eclipse,

00:53while the other, 144 meters behind,

00:57will study the halo. Using this method to simulate six hours of eclipse by day,

01:02the two satellites must be coordinated to the nearest millimeter,

01:05a position never previously achieved. Among the mysteries scientists are

01:10hoping to uncover

01:11is why the temperature of the corona reaches millions of degrees

01:15while the surface of the Sun is only 6,000 degrees.
