A stay/no stay decision for the lunar lander was made based on the questions: Is the Lunar Module (LM) stable on the lunar surface?; Are there any time critical systems failures or trends indicating impending loss of capability to ascent and achieve a safe lunar orbit?; and Is there loss of capability in critical LM systems? The sequence of these decisions is given as a time after touchdown on the surface of the moon. After the decision to stay is made the next task is to checkout status of the lunar module. While the status of the lunar module is checking out certain conditions, the Command Service Module was also engaged in certain checkout activities.", "item_img_path" : "https://covers4.booksamillion.com/covers/bam/1/28/916/435/1289164355_b.jpg", "price_data" : { "retail_price" : "17.75", "online_price" : "17.75", "our_price" : "17.75", "club_price" : "17.75", "savings_pct" : "0", "savings_amt" : "0.00", "club_savings_pct" : "0", "club_savings_amt" : "0.00", "discount_pct" : "10", "store_price" : "" } }
