How private enterprise is solving the vulnerability of satellites to military attack
Link here. The essay provides a nice overview of the U.S. military’s present conundrum on protecting all American satellites in orbit, not just military ones, and what it is beginning to do to solve it, now that the Space Force exists.
The approach is following three paths, with only the last two having any hope of success. First, the Biden administration is trying diplomacy to convince space-faring nations to ban future anti-satellite tests. This approach has really little chance of success.
The other two avenues involve innovations from private enterprise, launching many small satellites as part of a large constellation and in-orbit servicing, repair, and refueling. The first creates redundancy, making it difficult for any enemy power to easily destroy U.S. assets. The second provides capabilities for both fixing important satellites as well as attacking our enemy’s without causing space junk. Both will become common in the coming years, and thus will become very viable tools for military use.

Please consider supporting my work here at Behind the Black. Your support allows me the freedom and ability to analyze objectively the ongoing renaissance in space, as well as the cultural changes -- for good or ill -- that are happening across America. Fourteen years ago I wrote that SLS and Orion were a bad ideas, a waste of money, would be years behind schedule, and better replaced by commercial private enterprise. Only now does it appear that Washington might finally recognize this reality.
In 2020 when the world panicked over COVID I wrote that the panic was unnecessary, that the virus was apparently simply a variation of the flu, that masks were not simply pointless but if worn incorrectly were a health threat, that the lockdowns were a disaster and did nothing to stop the spread of COVID. Only in the past year have some of our so-called experts in the health field have begun to recognize these facts.

I was just thinking.(strange)
But what is the effect and diameter of a nuclear explosion in space?
Such as if they set one off in orbit how large of an area would it produce a propulsive effect on nearby satellites? How close would it have to be to throw a satellite out of proper orbit?
I know they tested explosions in space before but did they ever actually move something with one?

The Defense Applications of Near-Earth Resources Workshop took place in La Jolla, California, on 15, 16, and 17 August 1983.
Participants in the La Jolla workshop proposed more than a dozen SDI applications for lunar and asteroid resources. What follows is a description of the top three applications in terms of the mass of lunar and asteroid materials required. Much of the wide-ranging prospecting, mining, and processing the La Jolla workshop advocated would lead to in-space manufacture of “armor” made of lunar aluminum, asteroid iron, and aluminum and iron alloys created by adding small amounts of metals launched from Earth. The workshop report noted that military space systems launched from Earth tended to be made as light-weight as possible to reduce launch costs; this made them fragile and vulnerable if attacked.
“On the other hand,” the workshop report continued, “if a relatively inexpensive (500-1000 dollars per kilogram) supply of construction materials became available high above Earth, defensive systems would likely be designed very differently, with greater capabilities and greater survivability.” Layered armor for an SDI missile-defense platform with a cross-sectional area of 20 square meters would have a mass of about 400 metric tons; 100 such platforms would thus require about 40,000 metric tons of armor.
Layered metal armor would blunt attacks by kinetic-energy weapons (that is, weapon systems that fired solid projectiles); for defense against particle beams or nuclear explosions, however, radiation shielding would be needed. After armor, the most important application of space resources in terms of mass was what the La Jolla workshop report dubbed “stabilizing inertia.” An enemy attack might cause a missile-defense platform to spin out of control even if its armor shielded it from damage. Mounting the platform on a chunk of raw asteroid would greatly increase its mass, making it much harder to shove around.”
“Third after armor and stabilizing inertia were heat sinks. The La Jolla workshop anticipated that missile-defense systems – for example, missile-destroying lasers powered by exploding nuclear bombs – would generate a great deal of waste heat very rapidly. Without places for the heat to go, they could easily destroy themselves. A heat sink might take the form of a large tank of water or large block of metal.”
That was all before this discovery
