Artificial Skies

Look up on a clear night and you might see the moon, stars, an airplane, a Pentagon observation balloon, police drone, one of Elon Musk's Starlink communication satellites, or a Loon balloon from Google's Alphabet fleet that can provide wireless internet access to rural and remote areas.

     Shortly after a Starlink rocket launch, a satellite is almost as bright as the North Star, a magnitude 2. When it reaches its orbiting height 342 miles above Earth, unless sunlight hits just the right angle, the satellite dims to magnitude 5 to 7. Beginning three to four hours after sunset in a summer, satellites can be visible to the naked eye all night.

     With U.S. Federal Communications Commission (FCC) approval, Musk's SpaceX program is in the process of launching 12,000 satellites in a Starlink network designed to facilitate high-speed, global broadband internet access. Sometime in June, 2020, a SpaceX Falcon 9 rocket is expected to launch the eighth batch of satellites, about 60 more, for the broadband network.  His artificial satellite constellation raises concerns about space safety and the impact on ground-based telescopes exploring deep space.

     At different heights above Earth, the orbits of satellites pose different problems. At about 300 miles or less, atmospheric drag downs and vaporizes satellites. Starlink system satellites designed to orbit 700 miles above Earth are too high for a quick and disintegrating re-entry. If satellites carry fuel, working ones can be maneuvered back to higher levels, and high-level ones that no longer work can be lowered and subjected to disintegration. Of course, the presence of fuel in a satellite increases the chance of an explosion.

     Whether working or out-of-service, at any level above Earth satellites can collide and break apart into "space junk." Fragments of debris go into their own separate orbits ready to cause additional collisions and, therefore, even more space junk. That is what happened when the Chinese sent a missile to hit a satellite no longer in use. Resulting shrapnel fanned out into numerous orbits of space junk. Potentially, damaged debris could necessitate avoiding whole regions of space.

     Besides the danger of collisions, bright satellites that compete with the stars are a problem for astronomers who have been exploring deep space for centuries. Since photographing objects light years away can require exposing an image for hours, satellites orbiting the Earth already spoil the view. Those who use radio telescopes to study the universe expect interference from satellite transmissions that use frequencies close to the radio waves from distant objects.

     Loon's internet balloons fly at 10 to 15 miles above Earth. With five to 10 balloons, Loon is especially useful in providing temporary service to an area in need of communication after a disaster. Service is now provided in Puerto Rico, Peru's rainforest, and Kenya.

     Problems associated with space, including satellites, balloons, spacecrafts, and military applications, are expected to worsen. In addition to the approximately 5000 satellites already orbiting Earth and 12,000 launched by SpaceX, the OneWeb company plans to add 650 and Amazon's broadband project would deploy 3200. Along with the satellites powering the U.S. GPS, other navigation systems: Russia's GLONASS, China's BeiDou, the EU's Galileo and OneWeb, now owned by the UK and India's Bharti Global, also have launched satellites. Unless atmospheric drag is allowed to remove space junk and satellites no longer in use, the likelihood of collisions and interference with deep space research will increase unchecked.

     At present, no international agreements govern the safe use of space, observes Dr. Lisa Ruth Rand, a research associate at the Smithsonian's National Air and Space Museum and post doctoral fellow at the University of Wisconsin. To date, the use of space seems to rely on the ambitions of Elon Musk, individual countries and companies, and aliens exploring new frontiers. Urgent international negotiations are needed, at least by Earthlings. 

   

   

   

Cost Out A Better Future

Democratic candidate for U.S. President, Andrew Yang, proposes sending every person over 18 years of age a government check for $1000 each month. Why? Human beings need food, shelter, and clothing every month. Yet, automation is expected to eliminate more and more of the ways people now earn the funds needed to provide these necessities, while corporations accumulate greater wealth by replacing employees with machines.

     Already, Yang notes, big tech companies, such as Facebook, Amazon, and Google, grow rich by packaging and selling the private information millions and billions of individuals supply free of charge.

     Technological changes require changes in other sectors of human life. When work requires manipulating information on a computer, the physical strength of men is unnecessary. Childcare is still necessary, but how it is provided and by whom need not be confined to unpaid natural mothers.

     Not only childcare, but $1000-a-month paychecks also would provide compensation for those whose time creates an enjoyable community life: the shoppers and clerks who get to know each other, community leaders who organize groups and boycotts to solve problems, gardeners who share crops with neighbors and plant flowers to beautify walking paths, visitors who watch sports with the homebound, families who attend religious services together, friends and relatives who celebrate birthdays with homemade cakes, cards, and presents, and those who write "Thank you" notes.

     Those dissatisfied with $1000 a month will innovate. Designs can be sleeker. Drugs can cure more. Experts can develop more effective teaching methods. Constitutions, standards, and collective agreements can harness, not only the temporary impulses of a mob, but also the independent actions of robots and AI. Dives can go deeper. Spacecraft can go farther. Games can be more fun.

     $1000 a month is a small price to pay for a better world.

   

Vietnam and U.S. Demonstrate the Value of Short Memories

Chances are, looking back on your life, you remember having an enemy who later became your friend. Kids also go through those off and on enemy-friend relationships, as do countries. Turning Germany into a friend after World War II proved far better than trying to condemn the country forever following World War I.

     In the U.S. we learned at Senator John McCain's funeral service on September 1, 2018 last Saturday, even though he was captured and tortured for over five years in Hanoi during the Vietnam War, the Vietnamese now recognize him as someone who helped bring about the reconciliation of the United States and Vietnam.

     Haiphong harbor, once mined by the U.S. during the Vietnam War, now is valued as an import/export hub needed to handle U.S. trade pulling out of China. In February, 2019, President Trump and North Korea's Kim Jong-un chose Vietnam for their meeting to discuss demilitarization of the Korean peninsula and lifting the crippling economic sanctions that keep North Korea from enjoying the prosperity South Korea and Vietnam now enjoy.

     Today, both the United States and Vietnam continue to contest China's claim to "indisputable sovereignty" over the Spratly Islands and their adjacent waters in the South China Sea. After declaring in 2015 no intention of militarizing its artificial islands there, China now has radar installations, reinforced concrete bunkers, and missiles on three Spratly Islands west of the Philippines, a compliant challenger dependent on Chinese investment. China also has landed bombers in the Parcel Islands disputed with Vietnam.

   Vietnam, nonetheless, with its powerful military force, successfully prevented China from locating an oil exploration rig in its waters. At home, Vietnam has experienced anti-Chinese protests. Meanwhile, in its ongoing challenge to excessive maritime claims by all countries violating the international Law of the Sea Convention, a U.S. destroyer's Freedom of Navigation Operation sailed within 12 miles of one of China's seven artificial islands in May, 2018. Then, the US canceled an invitation to China to participate in annual naval drills off Hawaii and invited Vietnam instead.

     Vietnam also has challenged China's claims in the South China Sea by building two of its own artificial islands on the Nanhua Reef in the Spratly Island chain. According to China, the reef where Vietnam built is only above water at low tide, and typhoon "Jasmine" washed away much of the reclaimed land dredged up from the ocean floor. China also was proud to add Vietnam used a technique inferior to the way China sucks up sand for its taller islands.

     Both low tech and high tech industries benefit from Vietnam's and the US's short memories. Check clothes labels, and you probably will see a number of items were made in Vietnam. At the same time, the oncology treatment IBM's Watson chose at Phu Tho General Hospital enabled a patient to move and eliminate the need for painkilling medication. Google Brain and technology experts also applaud Vietnamese Dr. Le Viet Quoc's effort to make deep learning a reality and to incorporate artificial intelligence (AI) into advertising research.

     At "Age of AI and Vietnamese Enterprises," a Hanoi summit on July 25, 2018, more than 400 AI, economists, and financial experts and delegates from Vietnam's leading firms heard Harvard's James Furman urge private-government cooperation on AI research and applications. Vietnam's own Deputy Minister of Planning and Investment told the summit's older generation to eliminate obstacles preventing companies from making full use of younger employees with math skills and an interest in new technology.

     Modeled on Silicon Valley, California, Vingroup JSC, a Vietnamese conglomerate worth about $3 billion, intends to consolidate its diversified businesses in VinTech City, where the focus will be technology development (including development of new generation materials), applications, manufacturing, and services. A sub-unit will house the Big Data Institution and Vin Hi-Tech Institution.Vietnam finds the key to using Big Data effectively is creating teams that include Big Data technology experts and those with a full understanding of the industry using the data. Working together, technology and industry partners are best able to incorporate unstructured data about customer activities, such as internet use and applications, with structured and semi-structured industry data in order to develop new digital products and services. Just like in the United States, Vietnam knows data found to have great long-term value for a company, needs to be protected from nearby and distant competitors, even if they are friends.
