The second phase consisted of the most comprehensive, detailed examination of the condition and construction of the Star-Spangled Banner to date, which provided critical information for later work. This included scientific studies with infrared spectrometry, electron microscopy, mechanical testing, and determination of amino acid content by a New Zealand scientist, and infrared imaging by a NASA scientist.
The second phase of the project aimed to thoroughly analyze the Star-Spangled Banner's condition and construction, providing crucial insights for future work. This involved scientific investigations using techniques like infrared spectroscopy, electron microscopy, mechanical testing, and amino acid analysis by a New Zealand researcher, along with infrared imaging conducted by a NASA scientist.
