on into what isn overt class effort vers sub orbital andhere is a very big dference, the general pubc doesn undersndgetting to space and gettg to orbit it is important to make that distinctio too a b orbil flight you need a termin velityf around mach 3. to get to orbit youeed mach 25it is a huge,huge, difference becau the eney required to at deals with the uare of theelocity, so sub orbital may be ninth in energy and/or bit 625 units of energy, sot is about one and a half perce of the ergy to get su orbit to orbit, sorry the were several efforts i that cegory that youould ow to orbital, there is jeff, who has an eort, and i know that is something -- >> is bran someinvolved in that. >>he bransom, absolely. not so much directly fro the technology sndpoint, but from he is funding that development and scaling compositein california. what are you doing? >> we are in the orbit cla. and it i a lot moreapital, and that is reall where we are pushing the ragged edge of what is physically possible. and last year we got to orbit, for thfifth timewith our rocket, and that was certaly a huge relief ana milestone.
