Lambert’s Theorem Know a lot about possible orbits connecting two points But analytical relationships rely on “ a how to get it? Must somehow select a an additional specification about the transfer path What to specify? Lambert: conjecture that given I.C.s 1 1 1 ( ) sin p n t t E e E = 2 2 2 ( ) sin p n t t E e E = 1 LL 2
