		<description>The same technology that enables microsats, allows many  small launches to rendezvous and add up to a large dose of fuel or resupply.  One critical thing about space launch is that the costs are so high.</description>

		<description>&lt;i&gt;What is less frequently pointed out is that a technological enemy could precipitate such a conflict unilaterally anyway, precisely because America has the most to lose.&lt;/i&gt;

An analogy: General Foulkes said that Germany was foolish to initiate the use of gas warfare on the Western Front, because the wind usually blew towards them.

The Allies would almost certainly not have used it, if the Germans had not used it first.

As the man who ran much of Britains gas warfare efforts, he ought to have known.</description>

		<description>35 Larry J:  I&#039;ve thought that one way to kill a hostile satellite would be to approach it and spray it with a liquid that would harden on contact and cover the solar panels, camera lenses, etc.  Kind of like throwing a net over it.

But spray-painting the Earth or star sensors is probably just as good if not better.</description>

		<description>The one problem with microsatellites moving around in orbit is that it takes a LOT of energy to move from one orbit to another, and there is no way to get this energy back.  And to accomplish the move, one has to throw something out of the craft (action-reaction) and there is a limited amount of propellent available for the purpose.  Ion thrusters might be a solution if you could wait; they produce a little thrust, but they expend much more energy and much less reaction mass.  (Momentum, which is what you need, is the product of mass and velocity; energy is half the product of mass and the square of velocity--which is why helicopters have such large rotors.)</description>

		<description>esmoore5 - thanks for the pointers, I hadn&#039;t read of Misty before. However, if amatuer astronomers were able to repeatedly find it, and Mike McMillen killed the follow-on program, plus some of the points made by other posters - the idea of truly stealthy satellites (as stealthy as the B-2 or F-22) sounds pretty challenging.</description>

		<description>&lt;blockquote&gt;Another option would be to attach a device that could be triggered at will to disable the enemy’s satellites. That way in the event of hostilities you could, in one move, wipe out the opponent’s capabilities. Effectively they would be blinded and rendered deaf and mute.&lt;/blockquote&gt;

To see how strange things get with strategic assets, check out the following related program:

Sometime in the early to mid &#039;60s, a National Research Council committee on anti-submarine warfare hatched, and allowed to leak, the following idea:

Drop small robotic devices near Soviet submarines as they left base (where we always had patrols). These devices would attach to the submarine. Periodically they would seek out the long trailing wire antenna on the submarine and cut it.

Why?

The committee was tasked with finding ways to prevent Soviet first strike attacks on the US. Their logic went as follows:

1) To make the strike successful (in those days), missiles must be launched from subs near our shores to minimize warning time

2) The submarines carrying the missiles had to be under positive control. The &quot;go&quot; code had to be transmitted by the highest authorities only when it was time to launch. Nobody wanted to hand a sub commander orders to start a global thermonuclear war in 10 or 30 days sailing time!

3) To minimize detection, the submarines needed to stay submerged, with no periscopes, antenna masts or buoys (I hunted submarines in those days from a P-3 Orion, btw). Thus the communication had to be by VLF or ELF. In either case, a very long trailing wire underwater antenna was required to get the radio signal.

4) If their was significant doubt about enough submarines receiving the go signal, the mission would not be launched.

5) The releasing of the information about this program was to create that doubt.

&lt;b&gt;Note:&lt;/b&gt; Whether the devices were ever built and deployed was highly classified and probably still is.</description>

		<description>If you want to permanently take a satellite out of action without leaving any fingerprints or debris, all you have to do is spray some paint on the Earth and/or star sensors used for attitude control. Most satellites will go into survival mode when they lose attitude lock. Survival mode means all non-essential electrical systems shut down (mission payload) while the people on the ground struggle to regain control. Within hours, the satellite&#039;s internal temperatures will cool down so heaters turn on to keep the propellant lines from freezing. Before long, the batteries are dead and the satellite is a piece of space junk.</description>
