Pp. 104–105 contain 4 images under third-party copyright, used by NASA by permission, that have been redacted from this file. The likely source of these images is <a rel="nofollow" class="external free" href="https://doi.org/10.1111/j.1749-6632.1965.tb20421.x">https://doi.org/10.1111/j.1749-6632.1965.tb20421.x</a> and a further investigation may reveal if and how long those images' copyright lasts. Once copyright in those images have been determined to expire, this file should be updated to restore the redacted images.</div>
