It had been conjectured that the sun’s interior was composed of still-molten magma, covered by a relatively thin crust: a seething flux of matter that manifested itself in volcanic activities. Only one of the volcanoes was visible from earth to the naked eye; but numerous others had been revealed to telescopic study. Now, as the Phosphor drew near to its destination, these others flamed out on the huge, slowly rotating orb that had darkened a fourth of the ecliptic and had blotted Libra, Scorpio and Sagittarius wholly from view.
For a long time it had seemed to hang above the voyagers. Now, suddenly, as if through some prodigious legerdemain, it lay beneath them: a monstrous, ever-broadening disk of ebon, eyed with fiery craters, veined and spotted and blotched with unknown pallid radio-actives. It was like the buckler of some macrocosmic giant of the night, who had entrenched himself in the abyss lying between the worlds.
The Phosphor plunged toward it like a steel splinter drawn by some tremendous lodestone.
Each member of the crew had been trained beforehand for the part he was to play; and everything had been timed with the utmost precision. Sybal and Samac, the engineers of the anti-gravity magnets, began to manipulate the switches that would build up resistance to the solar drag. The generators, bulking to the height of three men, with induction-coils that suggested some colossal Laocoön, could draw from cosmic space a negative force capable of counteracting many earth-gravities. In past ages they had defied easily the pull of Jupiter; and the ship had even coasted as near to the blazing sun as its insulation and refrigeration systems would safely permit. Therefore it seemed reasonable to expect that the voyagers could accomplish their purpose of approaching closely to the darkened globe, of circling it, and pulling away when the disruption-charges had all been planted.
A dull, subsonic vibration, felt rather than heard, began to emanate from the magnets. It shook the vessel, ached in the voyagers’ tissues. Intently, with anxiety unbetrayed by their impassive features, they watched the slow, gradual building-up of power shown by gauge-dials on which giant needles crept like horologic hands, registering the reversed gravities one after one, till a drag equivalent to that of fifteen earths had been neutralized. The clamp of the solar gravitation, drawing them on with projectile-like velocity, crushing them to their seats with relentless increase of weight, was loosened. The needles crept on… more slowly now… to sixteen… to seventeen… and stopped. The Phosphor’s fall had been retarded but not arrested. And the switches stood at their last notch.
Sybal spoke, in answer to the unuttered questions of his companions.
“Something is wrong. Perhaps there has been some unforeseen deterioration of the coils, in whose composition strange and complex alloys were used. Some of the elements may have been unstable—or have developed instability through age. Or perhaps there is some interfering force, born of the sun’s decay. At any rate, it is impossible to build more power toward the twenty-seven anti-gravities we will require close to the solar surface.”
Samac added: “The decelerative jets will increase our resistance to nineteen anti-gravities. It will still be far from enough, even at our present distance.”
“How much time have we?” inquired Hilar, turning to the navigators, Calaf and Caramod.
The two conferred and calculated.
“By using the decelerative jets, it will be two hours before we reach the sun,” announced Calaf finally.
As if his announcement had been an order, Eibano, the jet-engineer, promptly jerked the levers that fired to full power the reversing rockets banked in the Phosphor’s nose and sides. There was a slight further deceleration of their descent, a further lightening of the grievous weight that oppressed them. But the Phosphor still plunged irreversibly sunward.
Hilar and Han Joas exchanged a glance of understanding and agreement. They rose stiffly from their seats, and moved heavily toward the magazine, occupying fully half the ship’s interior, in which the hundreds of disruption-bombs were racked. It was unnecessary to announce their purpose; and no one spoke either in approval or demur.
Hilar opened the magazine’s door; and he and Han Joas paused on the threshold, looking back. They saw for the last time the faces of their fellow-voyagers, expressing no other emotion than resignation, vignetted, as it were, on the verge of destruction. Then they entered the magazine, closing its door behind them.
They set to work methodically, moving back to back along a narrow aisle between the racks in which the immense ovoid bombs were piled in strict order according to their respective elements. Because of various coordinated dials and switches involved, it was a matter of minutes to prepare a single bomb for explosion. Therefore, Hilar and Han Joas, in the time at their disposal, could do no more than set the timing and detonating mechanism of one bomb of each element. A great chronometer, ticking at the magazine’s farther end, enabled them to accomplish this task with precision. The bombs were thus timed to explode simultaneously, detonating the others through chain-reaction, at the moment when the Phosphor should touch the sun’s surface.
The solar pull, strengthening momently as the Phosphor fell to its doom, had now made their movements slow and difficult. It would, they feared, immobilize them before they could finish preparing a second series of bombs for detonation. Laboriously, beneath the burden of a weight already trebled, they made their way to seats that faced a reflector in which the external cosmos was imaged.
It was an awesome and stupendous scene on which they gazed. The sun’s globe had broadened vastly, filling the nether heavens. Half-seen, a dim unhorizoned landscape, fitfully lit by the crimson far-sundered flares of volcanoes, by bluish zones and patches of strange radio-active minerals, it deepened beneath them abysmally, disclosing mountains that would have made the Himalayas seem like hillocks, revealing chasms that might have engulfed asteroids and planets.
At the center of this Cyclopean landscape burned the great volcano that had been called Hephaestus by astronomers. It was the same volcano watched by Hilar and Rodis from the observatory window. Tongues of flame a hundred miles in length arose and licked skyward from a crater that seemed the mouth of some ultramundane hell.
Hilar and Han Joas no longer heard the chronometer’s portentous ticking, and had no eyes for the watching of its ominous hands. Such watching was needless now: there was nothing more to be done, and nothing before them but eternity. They measured their descent by the broadening of the dim solar plain, the leaping into salience of new mountains, the deepening of new chasms and gulfs in the globe that had now lost all semblance of a sphere.
It was plain now that the Phosphor would fall directly into the flaming and yawning crater of Hephaestus. Faster and faster it plunged, heavier grew the piled chains of gravity that giants could not have lifted….
At the very last, the reflector on which Hilar and Han Joas peered was filled entirely by the tongued volcanic fires that enveloped the Phosphor.
Then, without eyes to see or ears to apprehend, they were part of the pyre from which the sun, like a Phoenix, was reborn.

Rodis, climbing to the tower, after a period of fitful sleep and troublous dreams, saw from its window the rising of the rekindled orb.
It dazzled her, though its glory was half-dimmed by rainbow-colored mists that fumed from the icy mountain-tops. It was a sight filled with marvel and with portent. Thin rills of downward threading water had already begun to fret the glacial armor on slopes and scarps; and later they would swell to cataracts, laying bare the buried soil and stone. Vapors, that seemed to flow and fluctuate on renascent winds, swam sunward from lakes of congealed air at the valley’s bottom. It was a visible resumption of the elemental life and activity so long suspended in hibernal night. Even through the tower’s insulating walls, Rodis felt the solar warmth that later would awaken the seeds and spores of plants that had lain dormant for cycles.
