That's the kind of nonsense which makes developing new technologies bloody difficult in this field.

M2P2 has some promise in certain applications; & is definitely worth putting money into based on interim research - but it isn't some kind of magic bullet that NASA just has to put money into & the heavens miraculously open. It would be surprising if the money would be available for any kind of mission that could utilise an M2P2-type drive effectively for at least 15 years (about the time missions like Neptune orbiter or the Heliopause explorer could reasonably be considered); so pretending that simply researching the technology - which i stress: may not ever work; or not work in the form that Dr Wing Lee & his team have proposed it - is a case of NASA sitting on the technology is very much a case of Tumlinesque justice by press release.
