I believe this launch has been delayed once or twice?What was/were the reasons for delaying--payload delays, processing, etc.?Zubenelgenubi

It's very possible that HTV-5 could be delayed to help with the scheduling mess caused by the Progress M-27M failure that's also affected crew replacements. HTVs aren't flown often so it may seem that they are delayed but aren't (last was HTV-4 in late 2013).According to the ISS flight schedule thread, last updated 4/24/2015 (http://forum.nasaspaceflight.com/index.php?topic=32006.140) the flight is still up for August.

Figured I'd give the HTV-5 a good glamor shot; she may not get the attention of the other cargo vehicles, but she is quite efficient and modest!
