Page 4 THE TIPTON (INDIANA) DAILY TRIBUNE SkylabV Manned Space Experiments To Pay Close Attention to Food Quality SATURDAY. DECEMBER 26, 1970 HOUSTON — Provisions for the amenities of life have generally left much to be desired in spacecraft planning. During the relatively short flights of the past, the resulting discomforts have not been a prime consideration. • Flights of 28 and .56 days, such as those planned for Skylab starting in 1972, will require improved creature comforts for astronaut morale and efficiency. Food High on the list is food, a subject which has caused cnsiderable astronaut grum- b'irig in the past. Aerospace doctors and technicians are developing a food system designed to compensate partially for astronauts' long absence from home and to provide an approximation of warm, tasty food. For the first time astro-' nauts will prepare their meals from an assortment of frozen foods as well as items similar to those carried cn Gemini and Apollo flight missions. They will cook their own meals on a special food tray ' now being developed for Skylab. Frozen foods will be stored in a freezer in the Skylab orbital workshop. Palatable In addition to being the most palatable menu carried into space thus far, the Skylab food system is designed to meet the requirements and objectives of. an important series of medical investigations. These medical experiments are profoundly influenced by the nature and amount of food- that the as-. tronauts consume. An experiment in nutrition and musculoskeletal function includes at least three different investigations which demand "precise data on nutrient and mineral intake. An investigation into mineral balance depends upon complete knowledge of . every-thing the crew member consumes and excretes. An assay of body fluids is also dependent upon close surveillance of certain types of. nutrient intakes. Medical. Experiments In addition to these in. flight experiments a number of'.pre- and post-flight experiments rely on detailed quantitative knowledge o f what each crew member consumes throughout orbital flight. -•. . SKYLAB FOOD TRAY—A dietician at the Manned Spacecraft Center, Houston, holds a food tray being developed for Skylab. For the first time astronauts will prepare their meals from an assortment of frozen as well as conventional space foods. The food tray will measure 13 1 /2 by 15 by 4 1 /2 inches. It has individual recessed compartments into which the canned food item is placed for heating. The Skylab food system will maintain a caloric level between 2,000 and 2,800 calories. The diet will provide the minimum protein, carbohydrate, fat, minerals, and vitamins recommended b y the National Academy of Science. 70 different now being consid- missions. More than items are ered for Skylab Final selection will be made by each crew member. Skylab Menu The Skylab menu will consist of the following types: —Intermediate moisture: p.eeooked or fresh food with moisture content partially I educed, such as dry roasted peanuts, cookies and bacon wafers. —Wetpack: food with approximately 30 to 95 percent moisture content such as turkey and gravy, meat balls and sauce and chili. —Frozen: Precooked o r fresh food stowed below 10 degrees centigrade to retard spoilage, such as prime rib of beef, filet mignon, shrimp cocktail, and lobster new- burg. The food tray will measure 13 1/2 by 15 by -1 1/2 inches. There will be six of the trays, - one for each member, carried aboard the work shop when it is T launched from Cape Kennedy. The tray has individual recessed compartments into which the canned food item is placed for heating. • Selects Meal At meal time the crew member selects his meal from the food compartment, places the items to be warmed in the food tray, and then flips the i warmer switch for a three-course meal. Improved Method Makes Radioisotope For Use as Medical Diagnostic Tool CLEVELAND •— Radioisotopes, given to a patient either orally or by injection, are extremely useful diagnostic tools. These substances concentrate in vital organs and other areas of the body. The radiation emitted is recorded by a gamma camera, producing an image on a screen. This radiograph can show abnormal growths or blocked vessels ar.d measure blood flow. Scientists at the National Aeronautics and Space Administration's Lewis Research Center have helped make an advance in nuclear . medicine which could result in improved diagnosis and safety of patients. Iodine-123 During the past three years, Lewis researchers have perfected a 'method to produce the isotope iodine- 123 in a very pure form. The work has been part of a program with the U.S. Public Service of the Department of Health, Education and Welfare, Cincinnati. In tests conducted on more than 100 patients by the Public H.eilth Service, iodine-123 proved superior to the iodinc-131 in common use. Iodine-123 produced, at the Lewis Center, gives less of a radiation dose by a factor of 100 and makes a much c'.earer radiograph. Iodine- 123 has a half-life of 13 hours, while iodine-131 has a half-life of eight days. Benefits Cited One benefit from the lower radiation dose of iodine-123 is that,it can more safely be used to' take radiographs of infants. Iodine-123 is also seen as safer for public in general.-' the adult Despite these advantages, it has been difficult to produce iodir.e-123 in a pure form. Iodine-123 produced experimentally normally contains a number of undesirable impurities. Lewis pioneered a novel technique i° b r producing batches of highly pure iodine-. 123 with a cyclotron. The Lewis cyclotron generates highly charged particles charged particles which bombard tellurium-122, resulting in the formation of xenon-123. This new element is removed from tellurium by heating and the xenon-123 then decomposes to form iodine-123. A EC Machines Several doses of iodine-123 can be made by the Lewis cyclotron in a matter of a few hours. Since cyclotrons are in increasing use today, the commercial marketing of the isotope looks promising. In addition, the Atomic Energy Commission i s building two linear accelerators, high energy machines like cyclotrons, that could - produce enough iodine-123 to supply the entire United States. MAKING ISOTOPES—Employing this 60 -inch cyclotron, scientists at the National Aeronautics and Space Administrate n's Lewis Research Center, Cleveland, have perfected a technique to produce the radioisotope icdine-123 in a very pure form. As part of a cooperative program with Lewis, the U.S. Public' Health .Service of the Department of Health, Education and Welfare tested iodine-123 on patients and found it potentially safer than the currently used iodine-131. In medicine, such isotopes are used for radiographs that can show internal abnormal growths or blocked blood vessels, and can measure blood flow.
