Ed Lu är vetenskapsofficer på expedition 7 till ISS (International Space Station). Han har skrivit ett antal brev om färden till ISS och livet ombord som är mycket roliga och intressanta att läsa. Kolla in dem själv på "Ed Lu letters".

"When we drop the 2nd stage, there is a momentary drop in acceleration, then you are rapidly pushed back into your seat when the 3rd stage lights off. At 528 seconds after launch, the 3rd stage engines stop, and our capsule separates from the 3rd stage -- actually it feels more like we are ejected from the 3rd stage since it is quite a shove. Yuri has a pencil and eraser tied off on strings in front of him, and they begin floating telling us that we are now weightless. It is nice to be back in space!" - Ed Lu
