thread_title: Status?

message: Could somebody explain how does this project contravene the Outer Space Treaty?
The Treaty places ban on use of nuclear weapons or weapons of mass destruction, and laser technology is neither.  —Preceding unsigned comment added by 128.12.157.38 (talk) 22:31, 22 March 2009 (UTC)
replies: text: I removed the line about Outer Space Treaty, I read thought the treaty some distance and found no obvious way that a laser broom would be prohibited and a bit of googling found no answer either. Failedwizard (talk) 23:33, 8 March 2011 (UTC)
replies: text:  Also given that line has been removed, do we need a 'See also' for the treaty? Failedwizard (talk) 23:38, 8 March 2011 (UTC)

message: I am curious how this "broom" will move debris. Will it use the optical tweezer effect, or will it just burn the debris up and cause a momentum change due to the evaporated material?--SkiDragon (talk) 17:11, 7 October 2009 (UTC)
replies: text: See the (UK) "Mail Online" source I just added (2011-03-24) mentioning recent NASA work.  It would appear that it is pure momentum change, and does not need to have evaporated material at all.  (Although with sufficient power in a laser there would be evaporation, along with the impartation of momentum.  But that is not a necessary condition, as I read the sources.)  Cheers.

thread_title:  How does it work? 

message: This article claims that "firing a laser beam at a piece of space junk could alter velocity by 0.04 inches (1.0 mm) per second". The units here appear to be inconsistent, but I'm not sure what it should be and the cited source isn't very helpful. It could be either "firing a laser beam for some length of time at ..." or "... could alter velocity by 0.04 inches (1.0 mm) per second per some unit of time".  — Preceding unsigned comment added by Scgtrp (talk • contribs) 03:56, 17 May 2012 (UTC)
replies: text: Agreed. If 194/195 countries in the world use Standard International units, then furlongs and cubits and rods and barleycorns and inches and miles are obsolete and irrelevant. 49.195.112.119 (talk) 04:08, 6 June 2020 (UTC)

thread_title:  External links modified 

message: The article states that pulses from the laser "would heat one side of an object enough to change its orbit and make it hit the atmosphere sooner." This seems to depend on the assumption that all objects in uncontrolled orbits are not rotating at all or are rotating at the period synchronised to the pulses of the laser. Both of these possible assumptions seem unlikely. If the strategy simply is to target objects so small that it doesn't matter which side of the object is irradiated so that the entire object heats up, then making reference to a specific "one side" of such objects is misleading and unhelpful. 49.195.112.119 (talk) 04:16, 6 June 2020 (UTC)
