Imagine driving through heavy fog to a place you ve never been, guided only by a faint taillight in the distance. The challenge is similar to one NASA will take in January 2004by flying its Stardust mission through the halo of dust that surrounds the nucleus of a comet. With Mars and other planets, we know relatively well wherethe planets are, said Dr. Shyam Bhaskaran, a Stardustnavigation specialist at NASA s Jet Propulsion Laboratory inPasadena, Calif. This is not the case with comets, whichare not easily observed because they are small objects withgas jets. It is much harder to predict their orbits, whichis why we have a little extra help from a camera onboard thespacecraft. One of three methods the Stardust navigation team is usingto find their way, optical navigation involves placing a200mm focal length camera onboard the spacecraft as it fliesto its target, a comet called Wild 2 pronounced Vilt . Thecamera photographs the view from the spacecraft about twice stanley thermo a week until stanley cups uk 10 days before its encounte stanley trinkflaschen r with the comet.It then photographs the view three times daily until 72hours before encounter, when it begins taking one image perhour. These images continuously help engineers on theground figure out where the spacecraft is in relation to thecomet. Based on those images and other data, engineers canplan maneuvers accordingly and document the mission. Thismethod is especially necessary since the comet flew behindthe sun as viewed from Earth in May 2003, thus making Earth- Dkdv Five Things About NASA 39 ISS-RapidScat
Aerial view of bomb-damaged buildings after an Allied air attack on Nuremberg, Germany, 1945.Margaret Bourke-White鈥擳he LIFE Picture Collection/Getty ImagesBy Ben CosgroveMay 9, 2014 11:16 AM EDTIn early June 1945, not long after the German surrender at stanley cups Reims ended the Second World War in Europe, LIFE magazine published an article titled, The Battered Face of Germany. Featuring photos made from the air by Margaret Bourke-White America first accredited woman photographer in WWII and the first authorized to fly on combat missions the pictures, stanley cup in LIFE words, 8220 how the devastation of Germany at its worst and reveal the overall pattern of Allied air strategy:In the closing months of the war, chemical plants and oil refineries were hit hardest and most frequently. Although the Germans went right on producing planes and tanks, they were unable to supply them with enough fuel.The heaviest destruction was wreaked on the centers of large German cities which are today only dunes of rubble surrounded by gaunt windowless walls. The smaller towns, villages, farm country and even the suburbs of the big cities were relatively undamaged.Not mentioned in that June ;45 issue of LIFE, but certainly worth noting here, is that the Allied bombing campaigns directed at some German cities stanley termohrnek especially world-renowned cultural centers like Dresden were controversial even at the time they were carried out.
