On Earth, sunlight is filtered through the Earth's atmosphere, and solar radiation is obvious as daylight when the Sun is above the horizon.When the direct solar radiation is not blocked...

, can achieve a speed of two thousand miles an hour within a day.

The concept leads to the development of the sport of sun-yacht racing, and after several years of refining his ideas, Merton competes in what will be his final race. His hopes for victory rest on the low mass of his craft which he has made possible through advances in automation enabling him to fly it solo.

Soon, all but two of the competitors have dropped out, mainly due to damaged craft, and it is a straight race between Merton's craft and Lebedev
Pyotr Nikolaevich Lebedev
Pyotr Nikolaevich Lebedev was a Russian physicist.He made his doctoral degree in Strasbourg under the supervision of August Kundt in 1887–1891. In 1891 he started working in Moscow State University in the group of Alexander Stoletov. There he made his famous experimental studies of...

, entered by a Russian crew from the University of Astrograd. Although the Lebedev is lagging Merton's yacht, its senior pilot delivers a surprise blow by announcing that he plans to jettison his co-pilot in an escape capsule now that the earlier, navigationally intensive part of the race has finished.

Merton responds by recalculating his expected margin of victory and realises that the race is now going to be neck-and-neck at the finish line. At this point news arrives of a massive, and potentially deadly, solar flare
Solar flare
A solar flare is a sudden brightening observed over the Sun surface or the solar limb, which is interpreted as a large energy release of up to 6 × 1025 joules of energy . The flare ejects clouds of electrons, ions, and atoms through the corona into space. These clouds typically reach Earth a day...

. The race has to be abandoned, and there is no winner, though Merton abandons his craft with its sail still fully extended in order to ensure that it will be blown into interstellar space
Interstellar medium
In astronomy, the interstellar medium is the matter that exists in the space between the star systems in a galaxy. This matter includes gas in ionic, atomic, and molecular form, dust, and cosmic rays. It fills interstellar space and blends smoothly into the surrounding intergalactic space...
