I don't think that's a typo... evidently gas core nuclear rockets would have even higher Isp than solid core types (which have been tested to ~800-900 sec.) - being able to heat the H2 to higher than 2000 K or so without worrying about melting the core is probably the dominant factor in that. -dave w _______________________________________________ ERPS-list mailing list [EMAIL PROTECTED] http://lists.erps.org/mailman/listinfo/erps-list
