But it seems that, aside from an engineering breakthrough, we can’t really shorten these times - and he thinks it’s unlikely we’ll send humans in five decades, unlike the 2030s as Nasa believes.Bull puckey. That may be true for NASA, particularly in lieu of all the budget cuts, but it isn't true for the DoD black budget programs.
