"Addressing the Navigation Challenges of the Apollo Moon Landings: an Irishman's Story"

By Pat Norris of NASA's Apollo Mission's Crew

 

ABOUT THE LECTURE

Fifty years ago Apollo 11 was piloted safely to the Moon's surface by Neil Armstrong despite being ~6km from its intended landing site.  The navigation error was caused mainly by effects of the Moon's gravity field not included in the mathematical model used in the mission control software. 

Pat Norris was one of many engaged in trying to resolve this problem which had first been noticed two years earlier with the robotic Lunar Orbiter mapping satellites.  He describes the challenges faced and also relates how precision navigation was achieved for the second Apollo landing, Apollo 12 on 19 th November 1969. 

Pat will also describe other Apollo navigation challenges he worked on including establishing appropriate longitude values for NASA's island-based tracking stations.

 

 


ABOUT THE SPEAKER

 

 

Pat Norris graduated from UCD with a BSc/MSc in maths in 1963/64, worked in the UK and then moved to the USA, working as a NASA contractor on the Apollo programme in Houston from 1967 to 1970 using tracking data from robotic and manned missions to develop navigation algorithms. He was awarded the Apollo Individual Achievement Award by Neil Armstrong in August 1969 and he is a Fellow of the Royal Institute of Navigation. Pat's 50 years in the space industry are outlined at www.pat-norris.com and his most recent book is Returning People to the Moon After Apollo Will It Be Another 50 years?
