Yes, they are. NASA's ad

Yes, they are. NASA has said that in Congressional testimony, as has Sen. Bill Nelson (D-FL).


But what does "looking" really mean? DOD and NRO will surely study
options for launching new satellites, but that doesn't mean that they
are seriously planning anything. And as I've said in other posts, I
find in unlikely that they would hitch their wagon to NASA after their
experience with the shuttle program.

Besides, we all know politicians will stretch the truth when it means
funding for their district. And let us not forget that NASA also sold
the space shuttle to Congress based on its low cost and two week turn-
around time. Their cost estimates were wildly optimistic at best and
deceptive at worst. I'm sure some within NASA knew better based on the
compromises being made to the design to cut development costs, often at
the expense of operational costs.
