An Apollo-era NASA astronaut who was the primary individual born in Australia to coach for a spaceflight, Philip Chapman has died at the age 86, having by no means made it into orbit.
Chapman died on Monday (April 5) in Scottsdale, Arizona, virtually 50 years after he resigned from NASA as a result of what he noticed as an absence of alternatives for scientists within the astronaut corps.
“We’re saddened to be taught of the passing of Australian-born astronaut, Dr. Philip Chapman,” wrote the employees on the Canberra Deep House Communication Complicated, a part of NASA’s Deep House Community in Australia, on Twitter Wednesday.
Chosen in 1967 after he turned a U.S. citizen, Chapman was a member of NASA’s sixth class of astronaut trainees. Chosen with 10 different scientists, the group nicknamed themselves “The Extra Eleven” (the “XS-11”) in mild of their being instructed from the beginning that their probabilities of flying into area have been slim.
“What motivated me to affix this system is that I used to be deeply serious about area expertise. I used to be on this nation so I might work on area expertise. NASA referred to as for functions to turn into scientist-astronauts and that’s as shut as you may get to area expertise,” stated Chapman in a 1969 interview with ABC Information’ (Australia) Weekend Journal.
After present process fundamental astronaut coaching, together with spending greater than a yr studying tips on how to fly NASA’s T-38 supersonic training jets at Randolph Air Power Base in Texas, Chapman was assigned to assist roles for the then underway Apollo moon landings. Most notably, he served as mission scientist for Apollo 14, which might land Alan Shepard and Edgar Mitchell on the lunar floor whereas Stu Roosa remained in orbit in 1971.

“I am not in control of them, I’m coordinating them,” Chapman stated of the Apollo 14 science experiments and his position as mission scientist, in a news interview at the time. “I’m performing because the liaison between the experimenters and the crew.”
That distinction was some extent of competition for Chapman, who bumped into objections when attempting to counsel extra experiments for Roosa to carry out whereas circling the moon. There was an opinion throughout the program that the mission can be extra readily declared a hit within the press if the variety of aims have been stored to a minimal.
“I used to be dumbfounded by the concept that the way in which to extend curiosity in spaceflight was to reduce the helpful outcomes, and insubordinate Australian that I’m, I instructed Deke [Slayton, the director of flight crew operations] what I considered his new coverage,” Chapman stated in an interview for the 2019 guide “Shattered Dreams: The Lost and Canceled Space Missions” by Colin Burgess (College of Nebraska Press).
Nonetheless, Chapman prompt one of many extra memorable science demonstrations to be carried out on the moon.
“I recall commenting to [Apollo 15 support crew member and capcom] Joe Allen that the moon can be an excellent place to repeat Galileo’s well-known demonstration on the Leaning Tower of Pisa, as a result of the objects would fall slowly, and in vacuum,” Chapman stated of what would turn into Apollo 15 commander David Scott’s well-known “hammer and feather” drop in an interview with Emily Carney for her “This House Out there” column printed by the Nationwide House Society. “If I had considered it significantly, I’d have prompt it to Al Shepard on Apollo 14 — however maybe he would have most well-liked his demonstration of golf on the moon.”
“It seems that now we have to choose between shedding our competency as pilots or shedding our competency as scientists, stated Chapman, as reported by The Related Press on the time.
Born in Melbourne, Australia, on March 5, 1935, Philip Kenyon Chapman grew up and attended faculty in Sydney, incomes his bachelor’s in physics and arithmetic from the College of Sydney in 1956.
“I am delighted to have been an Australian — I am American now,” stated Chapman within the 1969 ABC Information interview. “I do not really feel it’s notably important by way of what I’m doing in this system. It’s a matter of sheer likelihood however I’m blissful it turned out that manner.”
After serving with the Royal Australian Air Power for 2 years and spending 15 months at Mawson Station in Antarctica as an auroral/radio physicist, he labored for a yr as an electro-optics employees engineer on flight simulators in Quebec, Canada, earlier than changing into a employees physicist on the Massachusetts Institute of Know-how (MIT), the place he earned his masters in aeronautics and astronautics in 1964 and doctorate in instrumentation in 1967.
After his 5 years with NASA, Chapman briefly labored on laser propulsion and the idea of solar energy satellites on the Avco Everett Analysis Laboratory in Massachusetts earlier than turning his consideration to industrial spaceflight. He was elected president of the L5 Society (at this time, the Nationwide House Society) and served on the Residents’ Advisory Council on Nationwide House Coverage after which turned chief scientist for 2 corporations, Rotary Rocket and t/area, which have been independently growing industrial reusable spacecraft to advance the area economic system and repair the Worldwide House Station.
In 2009, Chapman returned to the examine of space-based energy, founding the Photo voltaic Excessive Examine Group, to additional the event of solar power satellites.
Chapman is survived by his spouse of 37 years, Maria Tseng. He’s preceded in loss of life by his first spouse, Pamela Gatenby, with whom he had two youngsters, Peter and Kristen.
