Page 22 THE EVERETT ADVOCATE – Friday, July 19, 2019 A Bunch of Guys About to Turn Blue: Celebrating the Apollo 11 Landing By Dr. Glenn Marsch I f you want to land on another world, map it first. Since the two Viking missions in the 1970s, we have extensively charted the surface of Mars and the Mars Reconnaissance Orbiter spacecraft—equipped with the HiRISE Camera—is now resolving objects a meter in size. We could spot a Martian from space, barely, if we knew where to look. Someday, Lord willing, humanity will go to Mars. The HiRISE images will guarantee that we know what the landing site looks like, and that there will be no unpleasant surprises, like huge boulders or deep ravines that would make a Martian lander topple over. Starting in 1961, the United States similarly mapped the Moon in prepaBUYER1 Leitzke, Debora Bhatti, Sohail Y Barua, Ratul K Shrestha, Niroj ration for the Apollo missions. Before we sent astronauts, a series of Ranger and Surveyor landers characterized the lunar regolith (soil) as firm enough to land and walk on. But craters of every size pockmarked the surface. So we launched five Lunar Orbiter missions, and their powerful cameras carefully mapped the entire Moon to a resolution of a few meters. NASA engineers and scientists used these images to select landing sites for the Apollo missions. A prime landing zone would be flat and would have no large craters or boulders that could overturn the lunar module (LM) lander upon touchdown. For this reason the smooth Sea of Tranquility was selected as the target for Apollo 11. But what if you miss the landing zone?

Descending too fast in humanity’s first approach to the Moon’s surface, they overshot their target by about four miles. That’s not bad, given no one had ever done it before this real-time test and they had been traveling for a quarter of a million miles. Four miles out of a quarter million was pretty good for these pilots. But as Aldrin and Armstrong approached the lunar surface, Neil Armstrong realized that the lander was descending to an area littered with large boulders. To land there might be catastrophic. Using manual control, he delayed the landing by firing the engine to keep the LM aloft at about 400 feet to wing it to a landing site with few boulders or craters—like the large one ahead of SELLER2 them. Would they clear it? More importantly, would they have the fuel to clear it? A spacecraft must have the smallest mass possible, so the Eagle had very little extra fuel to burn on a search for a better landing site. As Armstrong looked, Flight Director Gene Krantz announced that the LM had 60 seconds of fuel remaining. Was the fuel gauge accurate? Still they looked. As they cleared what would later be named West Crater, Armstrong saw that the other side of it was relatively featureless, so he decided to land there. 45 seconds. Still not landed, but descending, very close. Armstrong’s heart rate was 158, his body belying his cool demeanor. With about 20 seconds of fuel left, Buzz Aldrin announced, “Contact Augusto, Antonio J Rouse, Ashley Tram, Hung T 15 B Street RT Babak-Rahimzadeh, Bobby Lucky 87 LLC CK RT 5 Bono, Joseph T Ward, Larry W Keenan FT Basnet, Bijaya K Mcewen, Kevin J Gallant, John S Keenan, Christopher Mcewen, Paula Gallant, Robert F Littman-Quinn, Jack ADDRESS 38 Carter St #309 25 Orange Ct Perpetuo, Edson F 33 Rock Valley Ave 15 B St 15 Hancock Ter 11 Baker Rd 10 Edith Ave #3 173 Bell Rock St #173 36 Lewis St #2 7 Maplewood Ave 22 Fairlawn St 142 Grover St Mckinnon, Michael Le, Hy T CITY Everett Everett Everett Everett Everett Everett Everett Everett Everett Everett Everett Everett Light,” as the LM touched the lunar surface and the engine shut down. Consummate professionals, Aldrin and Armstrong did not whoop and holler. After a 19-second, matter-offact exchange between Mission Control and the Lander, Armstrong announced, “Houston, Tranquility Base here. The Eagle has landed.” CAPCOM Charlie Duke responded from Mission Control: “Roger, Tranquility. We copy you on the ground. You got a bunch of guys about to turn blue. We’re breathing again. Thanks a lot.” Gene Krantz called out to all stations in Mission Control to give the Stay/No Stay response and all stations declaimed “Stay.” We had truly landed on the Moon.
