It is time for another ATOM AotM. This one, in particular, goes retro and ties into concepts from the early days of The Futurist, back in 2006. This award also dispels the misinformed myth that 'we can no longer send a man to the Moon like we did in 1969-72' or, even worse, that 'human progress peaked in 1969'. If anything, progress in space-related advancement has been steadily on an exponential trendline.
The first man-made object to be placed into orbit and send back information from orbit, was Sputnik in 1957. Since that time, satellites have risen in number and complexity. But the primary cost of a satellite is not the hardware itself, but rather the cost of getting it to orbit in the first place. While the early data is sparse and the trendline was not easy to discern, we are now in an inflection point of this trajectory, enabling a variety of entities far smaller than governments to launch objects into orbit. If the trendline of a 10x reduction per decade is in fact manifested, then a number of entirely new industries will emerge in short order.

The emergence of private enterprises that can create profitable businesses from space is an aspect of the 21st century that is entirely different from the capital-intensive government space programs of the second half of the 20th century. From geospatial data to satellite-derived high-speed Internet, the era of commercial space is here.
SpaceX has already begun the Starlink program, which advertises 1 Gbps Internet access for rural customers. It is not yet apparent how SpaceX will upgrade the hardware of its satellites over time, but if the 1 Gbps speed is a reality, this will break the cartel of existing land-based ISPs (such as Comcast), where the gross margin they earn on existing customers is as high as 97%. Needless to say, high-speed access available to the backwaters of the world will boost their economic productivity.
Other efficiencies are on the horizon. 3D Printing in space is very pragmatic, as only the 3D Printing filament has to be replenished from Earth, and finished objects are simply printed in orbit. As the filament never has an awkward shape, it is far less expensive to send unprinted filament into an orbiting 3D printer. Asteroid mining is another, and is an extension of the fundamental ATOM principle of technology always increasing the supply of, or alternatives to, any commodity. The prices of precious metals on Earth could collapse when asteroid mining reaches fruition, to a much greater extent than oil prices plunged from hydraulic fracturing.
But the falling cost of launch per unit weight is only half of the story. To see the second exponential, we go all the way back to an article from April 22, 2006, titled 'Milli, Micro, Nano, Pico'. The point here is that the ability to engineer smaller and smaller (integrated circuits with 5 nm transistors), at greater and greater scale, comprise a double exponential of technological intricacy and integration. Surely, this has to result in a modernization of the electronics sent up into space.
Consider that the major unmanned spacecraft that NASA has launched, such as the Pioneer, Voyager, and Cassini probes. These were electronics from the 1970s, with designs that are not being updated to this day given that the New Horizons probe (launched in 2006) was still the same size. We know that an electronics design, from 1975 to 2020, is expected to shrink in both size and cost by a factor of over 1 million. If a supercomputer the size of an entire room in 1975 is less powerful than a 200-gram Raspberry Pi system in 2021, then why is NASA still launching one-ton devices that have incorporated none of the advances in electronics that have happened in the last 45 years? The camera and transmitter on Voyager 2 are surely far less powerful than what exists in 2021 smartphones.
Given the continued shrinkage in electronics and decline in launch costs, it is long past time for thousands of Voyager-type probes, each the size of a smartphone, to be launched in all directions. Every significant body in the Solar System should have a probe around it taking pictures and other readings, and the number of images available on the Internet should be hundreds of times greater than exists now. This will happen once someone with the appropriate capabilities notices how far behind the electronics of NASA and other space agencies are.
Hence, this ATOM AotM makes use of up to three exponential trends at once. But the decline in launch costs per unit weight alone has immense implications.
This will be the final ATOM AotM posted on this website as an article. Future instances will be on my new YouTube channel, which I hope to inaugurate in February.
