Millions of astrologers around the world know that Saturn brings limitations and Jupiter brings success. Uranus brings technological advancements. (trines & sextiles are good, squares & oppositions are bad, conjunctions vary with planets). Just have a look at some of the following dates:-
4th Oct 1957: Sun and Jupiter sextile Uranus.
Sputnik I launched successfully.
3rd Nov 1957: Sun square Uranus
Sputnik II launched successfully but the dog, Laika, died after a week in orbit.
12th Apr 1961: Sun and Venus trine Uranus
First human in space, Yuri Gargarin, launches successfully.
20 Feb 1962: Sun having just opposed Uranus
Successful but there was an unexpected electronic malfunction with the heat shield warning system (Uranus rules electrical equipment).
15 May 1963: The exception: Sun square Saturn
Several things went wrong with the Project Gemini trip.
Gordon Cooper's space-suit persistently overheated.
The water supply system failed.
He felt dehydrated and dizzy.
The automatic steering refused to work and had to be operated manually.
(Note: These are all typical Saturn-related problems!)
22 Jul 1969: Jupiter exactly conjunct Uranus: First humans on the Moon
Mission successful, a giant leap for mankind. Is this beginning to form a pattern?
So, the lesson seems to be to attempt rocket launches when Uranus is favorably aspected to give the expedition the maximum chance of success.
