John J. Hillman, 67, a NASA astrophysicist who did work on the atmospheres of planets, the composition
of comets and the preservation of  the Star-Spangled Banner, died of ocular melanoma Feb. 12 at his
home in Columbia.
Dr. Hillman was a senior scientist at NASA's Goddard Space Flight Center and was also a gourmet chef,
award-winning floral designer and certified copyist at the National Gallery of Art, where he particularly
enjoyed  working on the paintings of William Harnett and Orazio Gentileschi.

His interest in art led him to learn of the National Museum of American History's project to preserve the
Star-Spangled Banner, the American flag that withstood the British bombardment of Fort McHenry in 1814.
He called Suzanne Thomassen-Krauss, the museum's senior textile conservator, and offered her a way to
examine the flag using infrared light. He had in mind NASA's one-of-a-kind Acousto-Optic Imaging
Spectrometer, which had been developed for space research but could reveal deteriorated and soiled
areas of the flag not visible to the eye.
It was an opportunity to gather information in a way we wouldn't have been able to gather in any other way
and at a time before we would have lost that opportunity,  Thomassen-Krauss said.
Because the flag was on display, the team was required to work at night. The camera could see layers of
brushwork and underdrawings and could determine the pigment used in the paint, which is useful in
distinguishing an authentic piece from a forgery. Dr. Hillman noted at the time that the technology also
could be used in skin cancer research and for analysis of  prehistoric sites.
Thomassen-Krauss and her team worked with Dr. Hillman for two weeks, just before the flag was taken down for restoration. My
team still regards  working with him as one of the highlights of our work, she said.
As interested as he was in that project, his work was mainly in the heavens. He helped develop state-of-the-art instrumentation
used for  astronomy, and in 2002 he told Scientific American magazine about an airborne laboratory carrying high-speed
cameras, radio receivers and human observers that was tracking the Leonid meteor storm over Spain. The work,  Dr. Hillman
said, promises an important and unique database for the development of instruments targeted at
in situ sampling of cometary     
materials and for the future definition of comet missions.
This was a man who loved to learn. When one of his daughters started a floral shop, Dr. Hillman helped out and entered a
contest at Washington's home and garden show for flower arranging. He won first and second place, his wife said.
He was born in Fort Jay, N.Y., and grew up in Washington, graduating from Chamberlain Vocational High School in 1956. He
went to college full time for one semester, married in 1958, then combined family and night school with  work for the next 20
years. He received three degrees from American University, all in physics: a bachelor's in 1967, a master's in 1970 and a     
doctoral in 1975.
Dr. Hillman joined NASA in 1969, working in a variety of positions in atomic and molecular physics, metrological standards,
atmospheric sciences,  astronomy and astrophysics before his last position, as senior scientist in the Laboratory for
Extraterrestrial Physics.
As visiting senior research scientist at the University of Maryland's Department of Astronomy, he was co-director of the College
Park Scholars in Science, Discovery  the Universe. He was a member of the Church of the Resurrection in Burtonsville.
He was a member of the American Association for the Advancement of  Science, American Astronomical Society, American
Physical Society and  American Geophysical Union. He wrote or co-wrote 80 papers for publication.
Survivors include his wife of 47 years, Patricia A. Hillman of Columbia; five children, Kathleen Martin of Sykesville, Karen Stott of
Sykesville, Kimberly Housman of Marriottsville, John Hillman of Eldersburg and James Hillman of Mount Airy; a brother, William
Hillman of Fulton; and 12 grandchildren.
