Last night I was inspired to take photos of a dramatic moonrise appearing above the Cascade Mountains in the Pacific Northwest. It was an exceptionally clear evening, which enabled the luminous clarity of the moon to reveal its turbulent history.

In fact, the Earth shares some frightening historic parallels with all of its neighboring planets within our solar system. Indeed, of all world’s collateral past and future events, it is the asteroid or comet nemeses which present a potential close encounter of the worst kind!

Ignorance Is Bliss

Since the beginning of time, on a nearly daily basis, these extraterrestrial objects known as an asteroid come perilously close (relative to celestial distance) to our planet Earth. NASA scientists developed a method of categorizing Near Earth Objects (NEO) for tracking the orbital path of asteroids and comets. The space agency’s Near-Earth Object Observation (NEOO) Program, often referred to “Spaceguard” tracks and catalogues celestial objects coming to within 30 million miles (96,560,400 kilometers) of Earth. Ground and space-based telescope resources are used for increased surveillance and tracking of these unwelcome space nomads.

Potentially Hazardous Asteroid (PHAs) is what NASA currently uses for its parameters to gauge an asteroid’s potential impact threat to the Earth. If an asteroid is projected to travel within the moon and Earth’s orbit, it’s considered a potentially Earth-impact threat and depending on its specific trajectory, it is then placed into groups (Athen, Apollo Amor) for enhanced analysis. If a PHA were detected, it should not be assumed that an imminent Earth-collision is about to happen, however, understating or ignoring this catastrophic potential could lead to an early and permanent retirement of most life on Earth.

Blinded By The Light of Day

On February 15, 2013 the asteroid 367943 Duende was long-predicted to approach and pass dangerously close to Earth. On that morning, just after sunrise near Chelyabinsk Oblast, Russia a 20 meter sized meteor exploded as it entered the Earth’s atmosphere from a shallow angle. A radiant superbolide meteor blast occurred at an elevation of just under 30 km (18 miles) creating an intense light brighter than the Sun.

The estimated energy released was equivalent to approximately 500 kilotons of TNT, upwards of 30 times the explosive energy of the atomic bomb detonated above Hiroshima. Regional hospitals treated approximately 1,500 people for injuries and at least 7,000 buildings were damaged in half a dozen cities as an indirect result of the meteor’s shock wave.

The Chelyabinsk asteroid literally snuck under the radar as not all 15 meters wide, near-Earth objects are tracked and catalogue. The trajectory of the asteroid aligned so close to the Sun that it was not visible to the instruments responsible for locating such objects.

Within 16 hours after this unexpected event, the forecasted asteroid 367943 Duende perilously flew past Earth by 27,700 km without incident. In the days that followed, there were increased sightings of bright meteors streaking through the night sky. International space agencies and sources concluded that due to the divergent trajectories of the two celestial objects, they could not possibly be related. Consequently, this event illustrates how unprepared the World community currently is for developing essential contingencies to mitigate the range of potential dangers that asteroids present.

A Sobering Series Of Events

By coincidence, the Chelyabinsk event is cited as the second largest asteroid to impact the Earth’s atmosphere in recorded history. The larger, 1908 Tunguska event was caused from a 50 meter wide asteroid strike, which detonated at a 28,000 foot elevation. In an instant this event leveled approximately 800 square miles of Siberian forest that contained 80 million trees. The subsequent fireball is estimated to have released the energy equivalent of 185 Hiroshima atomic bombs.

The mother of all meteors to have collided with the Earth is the infamous Chicxulub asteroid, which impacted Mexico’s Yucatán Peninsula 65 − 66 million years ago. This mammoth asteroid caused a 10 mile wide crater and was from a 60 km (37.28 mile) fragment associated with the larger 170 km wide parent body. It is estimated the Chicxulub impactor released the equivalent 100 teratons of TNT, which also qualifies as the largest explosion to happen on the planet. This asteroid’s impact is credited with the Cretaceous-Paleogene extinction event, causing the worldwide extinction of most dinosaurs.

Size Does Matter

To put the potential horrific effects of asteroids into perspective, we can use past asteroid encounters to determine the likely scale of catastrophic damage that would likely occur.

An asteroid about 40 meters in width could level the largest cities on the globe. An asteroid or comet of 400 meters, similar in size to the asteroid which NASA has forecasted to come near the Earth on Halloween, would cause serious geological damage to an entire continent.

An asteroid about 1000 meters or larger, would likely end most life on Earth.

Trick Or Treat

Doomsday preppers are exceptionally excited regarding what NASA scientists are tracking and forecasting for asteroid 2015 TB 145. This 400 meter-wide (1,300 feet) is tracked using optical observatories and the radar technology of NASA’s Deep Network at Goldstone, California. Known as the ‘Great Pumpkin’ Halloween Asteroid, it is predicted to safely travel slightly beyond the moon’s orbit on October 31 at 10:05 a.m. PDT., before returning back on its circular journey into the vast realm of our solar system.

According to the Minor Planet Center, which catalogs Near-Earth objects (NEOs) this Halloween’s asteroid visitor is the closest known approach by any substantial celestial object until asteroid 1999 AN10 – which is a massive 800 meter sized object, whose orbit will return it near our moon in August 2027. ~

The Evolutionary Mastery Of Mars
In a forty-year period, the march towards making Mars inhabitable, astonished the most optimistic futurist. A sequence of technological events and economic opportunities (commonly known as the Third Industrial Revolution) converged seamlessly, allowing for safe and efficient journeys to the fourth planet from our Sun. Now, human life has sustained itself and is beginning to thrive on Martian soil.
On Earth, three decades into the third millennium, unstable global weather patterns caused by environmental abuse to our oceans, created extreme ripple effects with appalling famines and droughts. Then, suddenly a horrific rain of fire appeared as a sequence of catastrophic meteorite strikes plagued Earth— hastening humanity’s efforts to reach for the red planet. Of all the planets in our solar system — Mars has proven the best hope as a lifeboat and as a refuge for life taking hold.
Collaboration from the World’s nations, aligned rapidly to expand the colonies beyond Earth’s low-orbit. These outposts are in a stable formation at Sun-Earth Lagrangian Points:  L2, L4,  L5 and beyond. The various sites are used to support manufacturing, exploration and asteroid mining operations. Once established, they became “stepping-stones” towards Mars. Distant supply and launch stations are currently expanding at Sun-Mars Lagrangian points, circulating Mars.

Triumph Through Large Scale Asteroid Mining 
After the first three decades of daring space exploration in the late Twentieth Century, momentum was lost from lack of compelling mission. Chemical propulsion system limitations and lack of aerospace manufacturing beyond Earth’s orbit, slowed space exploration’s progress. Major superpowers lacked funding and political will to achieve great advances beyond low Earth Orbit.
As the Twenty-First Century progressed, collaboration of prime aerospace companies Boeing and Space X, developed, hybrid launch vehicles to accelerate humanity’s expanded presence in space. Private commercial ventures determined a great potential existed for mining valuable resources from near Earth asteroids and the Moon. The first company to successfully begin asteroid mining were Planetary Resources, with funding provided by wealthy technology luminaries.

Three-D Printing In Space – A Bridge To Infinity 
Early in the Twenty-first Century, new advanced technological tools were developed for flexible and efficient manufacturing. After revolutionary 3-D printing operations took hold in space, opportunities expanded rapidly to develop massive infrastructure beyond Earth’s orbit. Three-D printing devices made prefabrication of immense living and working sites possible on the Moon and various stationary points well beyond Earth’s gravitational influence.

Beyond Earth’s Orbit — Islands In Space
As the population of human enterprises rapidly expanded into deep space, exploration of Mars became practical and irresistible.
Using a spectrum of cybernetic applications, including artificial intelligences (AI), atomically precise manufacturing (APM) and 3-D printing provided cost-effective infrastructure manufacturing  to expand beyond Earth’s low orbit. The network of space station developments offers a growing population of skilled aerospace workers — dynamic living and work environments.
Molecular nanotechnology (MNT) produces an endless variety of manufactured goods for the inhabitants of interplanetary space. As the initial space stations quickly expanded and connected to one another, they became known as “Island Stations.” Adopting interplanetary codes for infrastructure support commonality is maintained for all inhabitants and guest visits by the National Aeronautics and Space Administration (NASA) and European Space Agency (ESA).
A network of stepping stone islands, which initially were used to extend the reach of asteroid mining operations from stable points beyond a low Earth orbit, is essential for colonizing Mars.

Revolution — Electro Magnetic Propulsion And Magnetic Shield Protective  Fields 
Revolutionary, electromagnetic propulsion systems, using super-cooled, conducting magnets and magnetoplasmadynamic (MPD) were developed for vastly superior performance over conventional chemical rockets. The time required to reach destinations such as Mars has been reduced significantly, by a factor of one year to less than two weeks. Initial funding from NASA and ESA, created a collaboration between Boeing, SpaceX and Virgin Galatic to produce these hybrid propulsion space craft. http://www.cbsnews.com/news/boeing-spacex-to-team-with-nasa-on-space-taxi/
The greatest threat to human space travel and colonization is from solar winds of magnetized plasma carrying protons and alpha particles, which can

Genetic Modification Through Astrobiology Provides Essential Benefits For Human Space Travelers
Evolutionary biology has provided advantages to meet the challenges of human travel into deep space.
The first generation of genetically modified humans was created to  limit the effects and risk from extended space travel. Microchip circuitry imbedded into tissue, gave humans expanded capabilities to assure space survivability, productivity, and flight operations. To combat muscle degradation from zero gravity-exposure, contractile protein levels were increased in muscle tissue.

Settlements On The Red Planet And Stages Of Terraforming
To survive solar radiation effects, early Mar’s settlers lived bellow the planet’s regolith (soil). Within less than a decade, the colonies developed their own localized magnetosphere, which became encapsulated environments within translucent domes — creating an atmospheric oasis. These aerodynamic structures offer shielding from dust storms and subzero temperatures. Now, an enriched quality of life on Mars includes ever-expanding domains of Earth like atmosphere for expanded development and life above the surface of the red planet.Meteor showers streaming above craters and cliffs during a Martian sunrise.

Massive mirrors are fixed in orbit above Mars for reflecting warmth back onto its surface, to provide a more temperate climate. Reflected light directed at Martian polar ice caps and its Carbon dioxide atmosphere of CO2 helps to keep thermal energy near the planet’s surface. As a result, a thermal runaway greenhouse effect is created to help build a thicker atmosphere. Release of microorganisms on the red the planet dramatically accelerates production, for intensifying greenhouse gas expansion.
Directing small asteroids with rich concentrations of ammonia to impact nitrate beds on Mars, releases high volumes of oxygen and nitrogen. These highly controlled asteroid strikes are providing substantial positive results to help develop an enriched atmosphere.

Nanotechnology is now employed on the surface of Mars and is dramatically altering landscape regions within various craters. Genetically modified plant forms are successfully taking hold and surviving some test environments. In conclusion, all of these achievements are creating a more Earth like climate, for efforts to terraform Mars.

Earth’s Sustainable Community On Mars
Self replicating machines using APM manufacturing allow infrastructure to develop at astonishing rates on the red planet. New scientific, engineering and mining communities are establishing themselves rapidly as they descend from orbiting stations and stationary platforms above the planet. The current population on Mars has surpassed 40,000 inhabitants and is projected to double within the next five-years.

The form of governance adopted by the colonies on Mars is based on a nonpolitical and international form of cooperation.  Asteroid mining and APM manufacturing are the largest industries associated with the Mars colonies.

Blinded By Light, In The Middle Of Night

16 Aug
Multimedia essay by: David Johanson Vasquez © All Rights  — Second Edition
For an alternative formatted view of this essay, please visit — http://www.BigPictureOne.wordpress.com

My photo wingman, Rick Wong and I headed into the heart of darkness in quest of the Perseid meteor showers. Mount Rainier National Park—was our ultimate destination. We chose the iconic, volcanic landmark for framing an infinite field of stars, which we believed was far from the glare of city lights. Traveling at night in Rick’s new Ford Fusion, using the hybrid’s voice recognition, made it easy to arrive at the park without using a map. Reaching our destination, luminous sparkling stars lit up the still night, but we were surprised with some uninvited competition, which nearly stole the show.

A stunning view of Mount Rainier reflected in Reflection Lake, with the summer stars overhead. The pink and orange glow on the left side of the mountain is light pollution emitted from the City of Tacoma, approximately 65 miles northwest.

 

We found an ideal location above Reflection lake, with the Cascade Mountains’ most famous stratovolcano in the background. An unexpected warm light was glowing behind Mount Rainier, which I reasoned, was a faint remnant from the earlier sunset. However,  the sun had set at least four hours earlier, so it couldn’t be the source of the illumination. Rick suggested “its light coming from the City of Tacoma,” located about 65 miles away. During a 20-second long exposures used to take images of the snow-capped mountain, I began thinking about the effects caused by light pollution.  

With a bright moon rising, we worked fast to keep up with the changing light, until its intensity eventually overpowered the stars.

With the moon steadily rising behind us, it too was causing us to shift focus on what to photograph. Like a giant diffuse reflector, the moon projected soft filtered sunlight onto a previously dark, formless landscape. As the moonlight overwhelmed the intensity of the starlight, it removed the opportunity for crystal clear views of the Milky Way, as well as faint meteor sightings. Being photo opportunist, we used the moonlight opportunity to reveal shadow-detail  on the south face of Rainier.    

The photographer appears in the dark, like some sorcerer conjuring an intense red light before Mount Rainier and her crown of stars above.

A Peaceful Paradise Lost

There’s a tranquil feeling while in the process of taking long exposures at night; it’s normally quiet with minimal distractions to overwhelm the senses or interrupt your focus. I personally enjoy these rare opportunities of solitude, to visualize an image using a minimal—Zen like perspective.

Distractions can be disruptive during these in-the-now-moments, as when cars coming around corners with intense, high-beam headlights.  More than once, clusters of cars with high beam lights appeared… just as the moon illuminated the mountain’s reflection onto a perfectly still lake. I quickly used my hands, in an attempt to shield the lens from light flare. Finally, the cars diapered into the darkness with no approaching vehicles until dawn.

Photo-illustration of the multiple effects of light sources which can cause light pollution by unintended distraction or spill-light.

Moving above the lake to find new angles for interesting compositions, I began to notice something, which I had not noticed before.  Lights of various colors, were coming from photographers bellow me, created by their digital camera’s preview monitors and infrared sensors for auto focusing. With the low light-sensitive Nikon cameras I was using, their monitor lights appeared like a bright flare in my long exposure photos. Now, I had one more unwelcome light source to deal with, which required strategic timing in making exposures to avoid the glare. 

Again, my thoughts returned to the issues of light pollution. I remembered back home when I wanted to photograph a full-moon  at night and a neighbor’s floodlight lit up the backyard. Their floodlight forced me to find the last remaining isolated shadowed corner of the yard.

My reminiscing was cut short by a distant, but bright, pinpoint of light flashing from bellow Mount Rainier’s summit.  Flashlights from mountain climbers near Camp Muir shined bright like lighthouse beacons in the semi-darkened rocks and glacier fields. Even the faintest light can shine bright at night as documented in World War II. Warships were forbidden from having any exterior lights on at night, including a lit cigarette, otherwise they could be spotted from great distances by enemy submarines.  

Lights from mountain climbers on the approach to the summit of Mount Ranier.

Encountering the Universe’s Brilliance

The improper, overuse of outdoor lighting has erased a fundamental and connecting human experience—encountering the universe’s brilliance with its galaxies and stars shining in the night sky! Making a visual contact with our own galaxy, the Milky Way, is one of the greatest shows seen from Earth.

In less than a century of civilization’s reliance on electric technology: two-thirds of the U.S., half of Europe and a fifth of people in the world—now live where they cannot see the Milky Way with the unaided eye. You can appreciate how we lost our stellar view by seeing aerial photos taken from orbiting spacecraft and the International Space Station. These startling images taken of Earth at night, reveals a man-made galaxy of artificial light, which cancels out much of the real ones in the sky above.  

Some years back, I was a part-owner in a small recreational ranch, in Eastern Washington’s, Okanogan County. Brining friends over from Seattle, it was often nighttime when we arrived. The instant of exiting the cars, was a startling event as the Milky Way’s intensity of light overwhelmed your senses. The “ranch” was remotely located, at about 5,000 feet in the mountains, near the Canadian border and 30-miles from the closest town. Days would go by where we didn’t see a car or even hear a small airplane go overhead… it was one of the most refreshing experiences of my life, to perceive nothing except wind going through trees and seeing only starlight at night for hours at a time.

 A television interview with the director of a major observatory in Southern California recounted when Los Angeles had its last electrical blackout —people were calling 911 and his observatory, reporting of strange, bright objects in the night sky. Actually what the callers were seeing for the first time, was the natural light from intensely shining stars of the Milky Way.

Besides forfeiting a life inspiring, wondrous view of the cosmos, there’s tangible losses associated with light pollution. Conservative estimates are 30 % of U.S. outdoor lighting is pointed skyward in the wrong direction, which wastes billions of dollars of electricity. The unnecessary practice of lighting clouds, burns more than 6 million tons of coal, which adds harmful greenhouse gas emissions, along with toxic chemicals into our atmosphere and water.

Further scientific studies indicate wildlife is suffering the ill effects of excessive urban lighting.  The City of Chicago has taken measures to turn off or dim its high-rise lighting to enable migrating birds to continue normal migration patterns. An increase in species of insects attracted to light, along with rodent attraction to bright city lighting is a growing concern to many scientists. 

Heavy equipment product shots never look quite this good. Scheduled improvements to the viewing area above Reflection Lake, had some equipment taking a nap, before going to work when the sun came up.

Education Is the Solution to Light Pollution

The reason light pollution has continued to multiply is, we have grown accustomed to its seemingly benign expanding presence. After all, probably no one can point to a single case of a person killed from overexposure to light pollution?  However, there is a correlation to growing health risk associated with overexposure to artificial light in the form of physical fatigue and damage to eyesight. In 2009, the American Medical Association established a policy, which supports the control of light pollution.

Municipal lighting codes are beginning to help define and eliminate unnecessary light pollution. Lighting enforcement can create a more pleasing environment, by reducing excessive urban lighting, which causes fatigue from glare and cuts down on unnecessary electric utility cost. Redirecting outdoor lighting away from the sky where it is needlessly wasted is a simple and easy solution.

Installing motion detector security lights are another efficient and productive mitigation strategy. For security purpose, a light which is triggered by motion is much more effective for crime prevention than a continuous floodlight. Motion detector lights have a clear advantage of focussing our attention onto an area where there’s a sudden change from darkness to bright-light.

The Milky Way is what we should be able to see at night if it was not for unrestricted light-pollution. You can see the Andromeda Galaxy in the right 1/3 of the frame. Nikon D700 – Nikkor 28mm lens @ F3.5 @ 20 seconds August 11 11:48 p.m.

The encouraging news is… the key to reducing light pollution is a simple matter of basic education and action. Public awareness of over-lighting requires a minimal expenditure, which will quickly pay for itself in energy savings and perhaps return the opportunity to experience one of the greatest shows seen from earth. ~

Light pollution glossary:

Urban Sky glow: the brightening of night skies over municipal and communities. Caused primarily from collective reflected light and poorly directed light, which is pointed upward.

Light trespass: light falling or spilling into areas where it is not intended. Also know as “spill light” such municipal streetlights, which go beyond indented illumination of street signs and sidewalks and lighting residential homes.

Glare: A direct, bright or harsh light, which causes discomfort or pain. The effects of glare can be reduced or eliminated with the use of a shield or filter.

Uplight: Light angled inappropriately upward towards the sky and serving no purpose. Uplift washes out the night sky and reduces opportunities for astronomers and stargazers to enjoy the beauty of the planets, moon and stars.

Clutter: Poorly planned, confusing and unpleasant use of multiple lights usually associated with urban or retail lighting. Retail business sometime competes by using overly bright, multicolored or pulsating light
