Talk:Delta IV

I'm not sure if this can be used for anything, but there's a nice photo of the Delta IV's second-stage here: http://mediaarchive.ksc.nasa.gov/detail.cfm?mediaid=24253 --NeuronExMachina 02:15, 19 Dec 2004 (UTC)

I read that Boeing and Mitsubishi were developing a more powerful upper stage engine called MB-60 for use on the Delta IV. However, I have not seen any updates for several years. Does anyone know if this is still being developed?--Todd Kloos 04:23, 24 Dec 2004 (UTC)
