Hi. Hope you all are well.
Chemical Propulsion Energy --- about 1 keV
Fission Propulsion Energy (reactor enrichment) --- about 1 MeV
Fission Propulsion Energy (100% enriched???) --- about 20 x 1 MeV
These are crude energy levels associated with these various rocket
etc. propulsion systems.
You can do better calculations of these levels at home.
Some rather crude calculations involving rocket kinetic energy show
me that a fully enriched Uranium propulsion system might go 100 times faster
in velocity than a chemically based propulsion system.
Of course, spaceship/rocket materials considerations and limitations of
astronauts's ability to endure/survive very large g forces may limit the
velocities and/or accelerations a spaceship or rocket can use.
A ground launched rocket using chemical propulsion could place a
spaceship using fission/fusion/chemical propulsion into space. One might then be
able to use enriched fission propulsion to increase a spaceship's velocity
to get to Mars sooner than just using chemical propulsion.
The Tito/Zubrin??? 2018 flyby (only???)mission to Mars is expected to
take 501 days or so. Maybe adding fission propulsion to this spaceship, one
could reduce this trip time to 250 days. This starts to sound more do-able
all the time. If fully enriched Uranium propulsion could be fully used
(not likely), the trip time
might take only 5 days.
The propulsion systems we are used to include: chemical propulsion,
fission propulsion, fusion propulsion, enriched fission propulsion and perhaps
several other propulsion systems which are being developed/used now. The
UFO and Ancient Alien shows allude to these several other (advanced???)
One you might be able to figure out yourself. The other is directly
described on one of these Ancient Alien/UFO shows (see shows on the H2 Channel
Perhaps someday soon we?? will be able to use an enriched
fission/chemical hybrid system to propel an Earth atmosphere spaceship which is
robotically controlled from the Earth's surface. Such a spaceship
could go significantly faster than a spacecraft with human beings aboard.
Is all this starting to sound familiar???
Wonder if Dr. Von Braun was a student of Goddard and others, by
studying the literature??? One UFO/Ancient Alien show describes another source of
Von Braun's Advanced Flight Systems (not necessarily Rockets) knowledge.
Won't go into it here.
Have a good week...
