Last day on (or out of) Earth

The world is so screwed up (possibly because of World War 3) that you're going to Space with your lover.

The spacecraft fails. You start to feel woozy from lack of oxygen, and realise that you are dying. Dying out of this world. Dying while gazing at the curvature of the Earth with all its deserts, grasslands, ice and seas, with its pale blue aura. Dying in heaven.

There's your lover next to you, dying too. You embrace until you both run out of oxygen, and fall to the Earth still locked in the embrace as one majestic meteor, vaporising into thin air.
