I was still wondering about the stars and the universe until I came to know  across about two great Muslim men.....in space science..

. Dr. Farouk El- Baz... born in Zagazig, Egypt.

who participated in The Apollo Programs and lunar landings as Supervisor of Lunar Science Planning....his outstanding teaching abilities were comfirmed by the Apollo astronauts...


.  Lieutenant General Kerim Aliyevich Kerimov........Azerbaijani-Soviet Russia.

who was a rocket scientist and his name was kept secret from the public...  works starting from the launch of the first satellite Sputnik , the first human spaceflight in space aboard Vostok 1.. the first automated space docking Cosmos 186 until the first space stations Salyut and Mir series.


I also found out from wiki... the early muslim astrologers and astronomers were amazing as their inventions and findings were acknowledged.





The Tusi-couple is a mathematical device invented by Nasir al-Din al-Tusi in which a small circle rotates inside a larger circle twice the diameter of the smaller circle. Rotations of the circles cause a point on the circumference of the smaller circle to oscillate back and forth in linear motion along a diameter of the larger circle.
 An illustration from al-Biruni's astronomical works, explains the different phases of the moon.

 

Medieval manuscript by Qutb al-Din al-Shirazi depicting an epicyclic planetary model.

Ibn al-Shatir's model for the appearances of Mercury, showing the multiplication of epicycles using the Tusi-couple, thus eliminating the Ptolemaic eccentrics and equant.
