UN-proposed lunar farside quiet area
« on: 06/22/2010 11:12 PM »
In response to
Here is a question for those with the ability to do calculations, can a J-130 lift two Centaurs stacked on top of one another to L2?  I am trying to develop a strategy to satisfy the Obama administration's idea for fuel depot demonstration, the idea is to loft a fully fueled Centaur to L2 with a precursor depot tech and gather information, also if possible I would like to know if the partially fueled lower Centaur can reach L2 as well so that we could gather two data points in one mission.

Using the normal chemical thruster routes
delta-V LEO to L2 is 3.43 km/s
delta-V LEO to L1 is 3.77 km/s

Note:  If the United Nations proposed rules on a quiet area on the far side of the Moon go through the propellant depot will end up at EML1.

What is this area?

Why would anyone want to put something at EML2 anyway?

Perhaps not at EML-2 proper. EML-2 halo orbits are ideal locations for comsats relaying to the lunar farside.
