Washington DC: NASA, 1976. First Edition, First Printing. Original wraps. 8 X 10 1/2 Inches. 121 PP. Very Good. Item #3462
Original stapled wraps. The June 4, 1976 NASA summary package of what was expected of the two original VIKING Mars spacecrafts. Details the investigations and operations NASA hoped to perform. Interestingly, the projected landing date in this publication was July 4th (hummm), but the craft did not land until the 20th. A few newspaper clippings have been laid-in resulting in some offsetting on a few interior pages. PO note of actual landing day and time in red ink on front cover. A scarce item. Light toning and wear.
