For those promoting other solutions, it would be nice to have your system-level studies identify the weakest links (perhaps ‘real’ magnetic nozzles, effective heat rejection, or energy supply accumulation). The entire vehicle is only as ready as its weakest link. If we reliably, what those weakest points are, then we know where to have research engineers concentrate their attention.the mission would become a derelict.”
Reading this reminded me of a little footnote about Einstein. Just finished Lawrence Krauss’a new book “A Universe From Nothing.” (Cosmology is really mind blowing these days!) Krauss relates something I knew and something that has been recently found. In 1936 an amateur astronomer, Rudi Mandl, wrote Einstein about using a star’s gravitational field as a lens (We , of course, know about the famous bending of light measurement.) Einstein made a little calculation and sent short paper
The AEC took from 1967-1982 to move from conception to an operating test facility. Some of the delay was caused by the annual budget battles that questioned the need for the facility after the cancellation of the fast breeder reactor program. The design was reviewed and approved by the Nuclear Regulatory Commission (NRC), though regulation of the facilities construction and operation was retained by DOE.
Paul, do you know someone who has worked out the best resolution possible one can image a extrasolar planet? I.e. taking into consideration pointing stability of telescope and so on.“any group that wants a mission of should better study the society it lives in to determine if that society will last long enough to get a return of data on the investment made.”
