Ice

The sounds of breathing pushed in. Cold seeped slowly through the surface of the suit. Stars drifted slowly through the view, slowly spinning again, in the same pattern. Time ticked by slowly... breathing.
Frost was building up on the glass view, branching and feathering slowly towards the center. There was no more fuel left, it had all leaked out on the impact. Plenty of air, that's what the suits were good at.. enough air for years. But the cold, the chilling cold couldn't be helped.
A little number on the heads up display said 10 km/s. I couldn't feel it. I couldn't see it.. couldn't see anything but those damn stars.
Closed my eyes, a soft touch. A gentle caress. Words whispered. Meaningless, distant, no more than memories. But the sensation, the brush of her hair...
A tear welled, drifting slowly away, slowly freezing into a shining sphere. She was safe. Did it matter? No, not quite, not at this point. But it did... irrelevant. It was a bad decision, the only regret. Life is too short for regret. It was too late now.
A malfunctioning component sparked briefly, lighting up the dark interior of the helmet, and scoring a mark into the butterfly wings of the frost. He cursed, a futile gesture, but a necessary one.
Smart retorts, sharp and biting, playful and harmless. Hunching intently when taking a picture. Hair clinging to her neck after a long run. Powerful gaze of triumphant discovery. Too much, too little. So far away. Another tear drifted slowly.
He removed the helmet, ignoring the soft alarm noises. The air hissed out of the suit, spraying into the dark void of space.

The helmet drifted slowly away, spinning ever so slightly. Never.

He evaporated in the atmosphere of a small, newly formed planet, 1.7 billion years later.
