The effects of global warming mitigated by moon-mining campaigns via inexpensive spacecraft-impacts eject lunar-dust scatters earthbound-sunlight in orbit.
Introduction
The previous article—of the series—discussed the relatively macroscopic and microscopic political-issues pertaining to combating the effects of global warming already. We link to the previous article’s introduction section, for readers interested in the cases for climate denial, alleged academic corruption … And the reason why climate change still seems to require serious attention.
This article continues with the science behind inexpensive lunar-bombardment; this may seem like a novel approach to extra terrestrial mining. If this investment reduces the effects of global warming and its associated costs in damages, then it is effectively-lucrative indeed.
Phased photonic propulsion 3PS third figure 3PS-iii caption. Question: how is lucrative space mining imagined? Answer:
Impacting Luna, our moon, at terrestrial escape speed with solar sail spacecraft, SC, kicks-up dust into at least one orbital-type.
This scatters Earthbound sunlight, and enriches industrial sectors such as agriculture, tourism, and utilities like water supply, as non-exhaustive examples. As the global population rises, and more greenhouse gases are produced, the effects of global warming are likely to exacerbate.
As effects of global warming are discussed, desertification of farmland leads to food shortages, higher prices, and disputes over resources.
Sunlight scattering mitigates costs in damages for wild fires, skin and infrastructure damage—bitumen roads and roofs as non-exhaustive examples. Spaceborne-clouds could cast shadows on narrow waterways, causing warm sea-water to flow into oceans—thereby cooling the aforementioned seas’ coastal countries.
In this way, celestial-mining is not effected by flying robot-bearing-SC, landing to dig up extraterrestrial regolith, for return to Earth. Large rockets need not ferry recognisably heavy mining equipment and ore between the surfaces of the Earth and her moon.
Rather, small pre-existing commercial rockets need only launch material sheets into low Earth orbit, LEO, inducing their rotation upon release. This is one of the least-complex embodiments of the presently described invention that our client has a patent applied for.
Strange New Worlds
Figure 3PS-iii follows from figure 3PS-ii, however the scaling is linear; operation is narrated, rather than labelled features being described. Depicted direct sunlight travelling from the right-hand-side to the left-hand-side of figure 3PS-iii causes the increase of spacecraft geocentric speed.
This was illustrated by overlapping grey broken elliptical curves, which were introduced in figure 3PS-ii of this series’ previous article.
The green elliptical broken curve shows SC impulse due to periodic exposure of the SC’s area to sunlight’s photon pressure.
The SC eventually travels close to Luna’s geocentric-orbit and could be flung further outwards, by Luna, towards Martian heliocentric-orbit.
On Earth, the effects of global warming are to be mitigated … By using Luna’s dust like a smokey lens to block some sunlight from orbit, by ‘eclipsing’ the sun.
Alternatively consider the SC impacting the Martian moon—Deimos in particular rather than Phobos.
The SC impacts Deimos ejecting her dust which acts as an orbital mirror. This reflects sunlight bound for the plains of Mars, to be focused upon her craters or valleys.
By comparison, the SC impacts Luna ejecting her dust which acts as an orbital lens. This scatters away sunlight bound for the deserts of Earth.
On Mars, we are not attempting to eclipse the faint and distant sun.
We rather place Sol’s reflection in Martian orbit to increase the surface-temperature of her craters or valleys—for human colonisation.
The astronaut landing on Mars would see two or more sun-like objects whilst standing in their warmed valley or crater.
That astronaut would install the cyanobacteria introduced in the present series’ previous article …. Search the ‘Introduction’ section. They would thus oxygenate the greenhouse gas atmosphere of the planet, Mars.
We briefly transcend dust-ejection orbital applications to exploit or prevent the effects of global warming on Mars or Earth respectively. The SC could be inexpensively sent to Mars for use in building structures in that planet’s environs or vicinity.
The SC may also orbit Luna herself.
In this case, the SC would be inexpensively sent to Earth’s-moon for use in building structures in that spatial region—instead.
We now return to our dusty application to mitigate the effects of global warming on the Earth. Depicted in figure 3PS-iii is what follows SC impact upon Luna’s surface; dust therefrom is ejected into some orbit. The particular orbit may be lunar-focal, the depicted geo-focal example, or helio-focal, depending upon the SC pre-lunar-impact terminal momentum vector.
The word ‘focal’, rather than ‘centric’ is used to prepare the reader for the possibility of highly eccentric, non-circular, orbits.
Despite these possibilities, only a geocentric circular orbit was explicitly depicted in figure 3PS-iii for the ejected lunar dust, regolith. The SC is photonically propelled … So it will impact the moon in temporal relation to its mutual spatial alignment with the Earth and the sun.
By methods undescribed for the sake of brevity, other SC can change the geometry of the dust cloud … Just as the impacting spacecraft can determine the dust-cloud’s orbit. However, figure 3PS-iii only illustrates a geocentrically-orbiting spherical dustcloud ‘eclipsing’ or obscuring the full intensity of Earthbound sunlight, once monthly.
This undermines our capacity to mitigate the effects of global warming by limiting sunlight’s intensity incident on Earth’s surface. What solution is available to us now?
Ideally, a high altitude circular geostationary and geocentric orbit for the dust cloud is desired. In practice though, an eccentric elliptical geo-focal-orbit is anticipated with its apogee near Luna’s geocentric-orbit and its perigee near Earth.
Figure 3PS-iii depicts such an orbit partially traced out by the green broken curve and its adjoining grey broken curve.
The cloud may eventually resemble a highly-eccentric analogue of Saturn’s rings; the ‘nebulous-sphere’ tidally disperses dust along its orbital trajectory. Whatever the geometry, dust scatters direct and intense earthbound sunlight, as depicted in figure 3PS-iii, cooling part of Earth’s surface.
Before considering the more complex embodiments of the present invention, let us first reflect upon a simple manifestation. We discuss some fundamental-physics of the mission in the present article, and then more applied-physics and engineering in the next.
All embodiments are capable of combating the effects of global warming according to our study.
Let us imagine a simple sheet of reflective material without rigid support structures like a mast or a boom. The sheet is folded in its centre like an umbrella, but without the rods to maintain its shape.
Placed inside a relatively small rocket to achieve LEO, the vehicle launches from the ground and spins in space. It releases the sheet, which also spins and flings out its corners like a centrifuge to reveal its square-like shape.
Precession
Since the sheet is spinning, we designate the axis, the imaginary line about which it spins, the roll-axis. If this roll-axis—as a non-exhaustive example—points towards the centre of Sol, the sheet will eventually precess—or wobble in its spin.
This is observed with spinning-tops and gyroscopes—such that the sheet’s roll axis will transcribe a circle like the solar circumference. The sheet will no longer point towards the centre of Sol, it will precess without the help of a pilot.
Even if the sheet does not precess, there may be an optimal angle for the roll-axis—with respect to the sun-Earth-axis. The optimal angle is the one which maximises the difference in magnitude between
Photonic drag when the sheet’s geocentric orbit approaches the sun, and
Photonic thrust when the sheet’s geocentric orbit recedes from the sun.
This, and the avoidance of aerodynamic drag from the Earth’s atmosphere is the minimal requirement for the present invention’s operation.
However, precession or wobbling away from and towards the optimal angle is inevitable unless actively corrected for. The simple embodiment discussed has no active correction; rather, both the precession, wobbling-spin, and the orbital, revolutionary, periods are synchronised.
Alternative Spacecraft
Economically reducing the effects of global warming on Earth’s surface does not imply that the rotating-sheet physics modelling was unsophisticated. Simpler mathematical models than that of a mastless and boomless solar-sail were considered—such as a more expensive geocentrically-orbit-receeding sunlit-expanding balloon.
The aforementioned balloon contracts during its geocentric-orbital-night-phase, its gas deposits into powder which is later heated upon daytime-geocentric-orbital-approach of Sol. The heated powder is synchronised to sublimate at the green orbital phase depicted in figure 3PS-i and figure 3PS-ii.
Concluding Part II of ‘What Solar Eclipses, Lunar Impact & Space Mining Have in Common’
Returning to the solar-sail embodiment: the sheet has the attitudes depicted in figure 3PS-i of the previous article.
For the reader’s convenience, I reiterate that upon geocentric orbital:
Solar recession, the sheet’s largest surface’s vector-area, or the roll-axis should align with Sol’s centre, and
Solar approach, the sheet’s largest surface’s vector-area, or the roll-axis should point ninety degrees away from its previous orientation … In other words, it ought to pitch or yaw by one-half-pi-radians.
This is a severe angular shift—but unavoidable precession will occur to make some angular shift to assist the present invention. However, in practice and for the sake of control, certain technologies may be added to the sheet … And we plan to discuss these in earnest within the next article.
