Johnny and Greg fed the navigation data into the ship's drive mechanism, checking and rechecking speeds and inclination angles. Already the Dutchman's orbital speed was matching the speed of Roger Hunter's asteroid ... but the orbit had to be tracked so that they would arrive at the exact point in space to make contact. Tom was assigned to the viewscreen, and the long wait began.
There was scarcely a trace of the original bones beneath the mass; even those forming the nasal sinuses on that side were replaced by a formation much resembling the cysts before alluded to, and full of abscesses. The progress of the disease was decisively marked in the inferior rim of the orbital cavity, where the osseous matter was being removed, and the morbid structure deposited."
It determines the velocity of rotation of the sun and of nebulæ, the existence and periods of orbital revolution of binary stars too close to be separated by any telescope, the presence of magnetic fields in sunspots, and the fact that the entire sun, like the earth, is a magnet.
The orbital paths of the planets are in the simple ratio of the distances; the weights or quantities of matter in different planets are in the subduplicate ratio of the same distances, as has been already proved; so that with every increase of distance a planet has more matter and therefore is moved more slowly, and accumulates more time in its revolution, requiring already, as it did, more time by reason of the length of the way.
In a few minutes he had elicited the information that the solar flare was now predicted to be terminated and the major part of the flare protons past their solar orbital position within another ten hours; that Earth co-ordinates had shifted, indicating their own orbital shift to be a trifle over thirty-seven kilometers north in the past eight hours. North? he thought.
If I went the other way I'd meet him going at over 10 miles a second in relation to his machine. He had the right idea. He told me to fall out to him at a greater than orbital speed. I will go just within the Earth's atmosphere till I get just under him, holding myself in the air by means of a downward acceleration on the part of the regular lifting power units.
As soon as the Lamia was on orbital watch, the Space Scourge was set down at the spaceport and work started on her. It was decided that Valkanhayn would take her to Gram; enough Nemesis people would go along to insure good faith on his part, and to talk to Duke Angus and the Tanith investors.
Another method of getting the distance from the sun is to measure the velocity of the earth's orbital motion, giving the circumference traversed in a year, and so the radius of the orbit. This has been done by comparing observation and experiment. The aberration of light is an angle 20" 48, giving the ratio of the earth's velocity to the velocity of light.
"Foster, three orbital turns, then front and center." Rip obediently spun around three times, then walked forward and stood at attention, trying to conceal his grin. "Foster, what does SOS mean?" "Special Order Squadrons, sir." "Right. And what else does it mean?" "It means 'Help! sir." "Right. And what else does it mean?" "Superman or simp, sir."
The cabin remnant was heavy, of course, but it was an irregular object, some twenty feet across. It was below orbital velocity, and wind-resistance slowed it. Even so, it traveled 47 miles to the east in falling the last 10 miles to Earth. It hit a hillside and dug itself a 70-foot crater in the ground. But there was nobody in it, then.
