Dagny luxuriated in the big bathtub. The tub was truly the size of a small swimming pool. She intentionally moved her body back and forth to get the water sloshing around. The curved walls of the tub rose over a meter above the surface of the pool to contain the water in the two-hundredths of a gee habitat. Lazy water waves propagated at barely half a meter per second towards the edge of the tub. The waves were then deflected upwards then inwards by the curved wall until they surged over her head to lazily fell back under the microgravity. The repeated deluges rinsed the soapy lather out of her hair and off of her nude body.
After a long, leisurely soak, Dagny climbed out of the tub to stand on the deck that surrounded the tub. A touch of a button caused warm air to blow on her until her skin was dry. She'd allow her hair to dry more slowly in the intentional warmth of the compact shelter.
Dagny used a built in terminal rather than the far smaller touch screen of her bracer to check the weather. She'd lingered in the tub far longer than she had expected. The stellar storm was now raging outside. The storm was even more intense than she or The Oracle had predicted. A tsunami of atomic nuclei, mostly ionized hydrogen and Helium, were blowing by at a velocity of over a thousand kilometers per second. The plasma density was also much greater than expected. Magnetic fields supplemented by half meter thick steel walls kept the radiation at bay.
Switching to the navigational subroutine, Dagny checked on the progress of the Magnetosail module. The compact, egg shaped, eight ton spacecraft had its magnetic sails fully unfurled to capture the energy and momentum of the stellar wind. The spacecraft was currently accelerating at over ten gees. The acceleration would wane as the plasma density decreased and its velocity increased until it was nearly keeping pace with the stellar wind. The egg would require barely two days to accelerate to its peak cruising velocity of a thousand kilometers per second.
Dagny utilized the storm shelter's tiny kitchen to prepare herself a meal. The label read "Macaroni and Cheese." She didn't know what that was. The prepackaged foods were a legacy from Earth. Even freshly rehydrated and heated, the taste was about what one would expect of food that had been manufactured two centuries earlier.
Awakening half a day later, Dagny checked the weather as well as the progress of the tiny cargo craft. The stellar storm was continuing to rage. The acceleration of the cargo craft had waned, but was nominal. The Magnetosail continued to boost into the void, carrying its precious cargo of human embryos.
A pang of guilt inspired Dagny to briefly contemplate returning to the starship. The five women in her crew were no doubt getting a workout from the dozen, young men. She knew that she was shirking her duty by intentionally avoiding the ongoing orgy. She could remotely pilot the magnetosail capsule from anywhere. The gondola had magnetic fields to ward off radiation. However; in the event of a power failure, she'd be quickly exposed to a lethal dose of radiation. She would remain in the shelter until the stellar storm abated.
A quick check of navigational data revealed that the magnetosail craft had veered slightly off its anticipated course. A magnetosail gets the best performance when it is running with the stellar wind. Although such a craft could have no keel to enable it to tack into the wind, it could broad reach a point or two off axis. No doubt the computerized brain was reacting to unexpected variations in plasma density and velocity to optimize boost with the expectation that it would adjust its course later.
Dagny knew that the glorified, electronic calculator was foolishly presuming that the stellar storm wouldn't abate prematurely. She knew better. Touching a few icons on her bracer transmitted commands to the little craft. However; the light speed time lag compelled her to wait for an hour while the commands propagated at the speed of light then acknowledgement of those commands returned to her. Even more time would be required to reveal the evidence of the required course correction.
To combat the boredom of waiting, Dagny accessed the video and data feed from the Sentry satellites. The observation platforms had been released, very covertly, by the starship as it was it was boosting out of Sol system centuries ago. Magnetosail transport modules had decelerated the Sentries so that they would lurk only a few hundred astronomical units outside the inner system. While neither the Transhumans or the Cybers had specifically forbidden the colonists from leaving Sentries behind to monitor the home system, they probably would not have approved. Shrouded by distance and the darkness of interstellar space, the sentries were effectively invisible. The probes would be extremely vulnerable if they were detected.
Although the sentry platforms had deployed optical interferometers with an effective aperture diameter of over a hundred meters, their resolution wasn't unlimited. They couldn't resolve objects on Earth that were smaller than a few dozen kilometers in diameter. However; that resolution was more than adequate to resolve the diminished oceans and greatly expanded continents of Earth.
While Transhumans and Cybers had denied the motive, they had not been content to allow the human population of Earth to diminish gradually and gracefully to inevitable extinction. They had installed a constellation of their solar power satellites at Earth's number one Lagrangian point. The enormous solar collectors partially eclipsed the sun.
Ironically; the Transhumans and the Cybers had cited the discredited theory of Anthropogenic Global Warming as a rationalization for their solar power project. That mass hysteria had not only wrought economic devastation. The competition for needlessly scarce resources had escalated to nuclear war.
Thanks to distance and orbital inclination, the eighty-four-thousand kilometer diameter habitat ring that girded the Earth at geosynchronous orbit was largely unaffected by the interdiction of solar energy. While the dwindling remnants of humanity had been languishing in the cold and the near darkness for centuries, the Transhumans and the Cybers had thrived in their ring around the world.
The orbiting megalopolis had grown continuously over the centuries. The most recent imagery that had been transmitted by the Sentries revealed a solid ring that was a thousand kilometers wide and dozens of kilometers thick. If one counted the inner as well as the outer surfaces, the surface area of the orbital ring was now quadruple the surface area of the Earth! The effective living volume was orders of magnitude greater. The ring around the world might be inconsequential compared to Niven's Ringworld around a star, but it was an awe inspiring marvel of engineering. It was estimated that tens of billions of Transhumans lived in the ring. The population of Cybers was no doubt at least an order of magnitude greater. Venus as well as Mars and Earth's moon hosted similar albeit much smaller, orbital megalopoli.
The Sentries were able to image the glaciers that had spread out from the Arctic during recent centuries. Most of North America and Asia as well as all of Europe we're covered by ice sheets that were kilometers thick. The Antarctic ice pack had expanded Northward to reach Australia. The cities of the once temperate zone of that continent were now under ice sheets kilometers thick.
A colder planet is a drier planet. The temperate zone and subtropical deserts had expanded to envelope the equatorial jungles. The Transhumans and Cybers had been unsympathetic to humanity. Earth's diminished and continually diminishing population no longer needed most of its once great cities anyway. Unlike humanity, neither the Transhumans or the Cybers cherished Earth's former biological diversity. They had ceased making pilgrimages to Earth's former ecological wonders generations ago.
Later
Another day had passed and the stellar storm had abated before Dagny boarded the gondola. She resisted the temptation to program the craft for a leisurely journey. She strapped herself in. She then programmed the craft for the journey. She'd accelerate at one gee for half an hour before decelerating for another half hour to arrive at the starship at Havensynchronis orbit.
A flaw in the design of the gondola was that the seats were not designed to be reversible. As the craft accelerated downwards, Dagny was subjected to one gee, negative. It was as if she was standing on her head! Since she was nude, her large, mature, pendulous breasts sagged towards her head rather than towards her belly. Her nipples presented themselves. Dagny couldn't resist the temptation to suck on her own nipples. She also inserted her fingers into her vagina to stimulate her gee spot as well as her clitoris. By the time the gondola began to decelerate, she'd brought herself to climax, twice.
