November 13th, 2014 a.d. – One thing came clear to me again last night: we have to send women and men to the comets to explore them. Therefor we need nuclear engines to making the trips a) possible b) affordable c) fast and d) safe. Those tiny robots on tiny probes – we could watch one of them last night – needing decades flight time and then nearly failing, if reaching their destination at all, cannot be the embassadors of the human species. With chemical propulsion the solar system cannot be settled, neither explored. There is only one way, the cosmic standard way: pulsed nuclear fusion directed to a narrow propulsion beam by means of the laws of quantum electrodynamics without the need of any chamber or nozzle. This is the perfect propulsion, provided by nature and the physical laws of the universe. This perfect propulsion was discovered theoretically in 1958 and was proved during the 70th. Todays comet space mission, presented in the internet, is very nice and thank you ESA for all this interesting automatically taken pictures. But this mission shows one thing clearly: it and it followers run into a dead end. When will we see the first real comet landing in human history?
