Correct way to bake turkey demonstrated by Uncle Sam's expert cooks. Washington, D.C., Dec. 4. Note to housewives: your turkey- baking troubles will be over and the bird you serve for dinner this yuletide will be tender, juicy and flavorsome if you follow the method used by the expert cooks at the Bureau of Economics, U.S. Department of Agriculture. Continual testing and experimenting with various recipes has taught Uncle Sam's cooks that many a prize bird has become a "ham" when improperly prepared. The best recipe - so far discovered by the Bureau of Economics - is demonstrated in the following set of pictures, made under the supervision of Miss Lucy Alexander, Chief Cooking Specialist. Miss Alexander, a graduate of Vassar and the University of Illinois, has been on her present job for eleven years. Mrs. Jessie Lamb, Assistant Cook, is stuffing the turkey under the watchful eye of Miss Lucy Alexander. The turkeys on the table will go into the ovens at regular intervals, and be tasted and judged by a group of experts who are determining which diet and feeding program will produce the best flavored meat.

CAPE CANAVERAL, Fla. – Technicians in the Payload Hazardous Servicing Facility at NASA's Kennedy Space Center install a specialized overhead crane onto the Fine Guidance Sensor, or FGS. The sensor will be lifted and moved to the Orbital Replacement Unit Carrier or ORUC, for installation. An FGS consists of a large structure housing a collection of mirrors, lenses, servos, prisms, beam splitters and photomultiplier tubes. There are three fine guidance sensors on Hubble located at 90-degree intervals around the circumference of the telescope. Along with the gyroscopes, the optical sensors are a key component of Hubble’s highly complex but extraordinarily effective “pointing control system.” The ORUC is one of three carriers that are being prepared for the integration of telescope science instruments, both internal and external replacement components, as well as the flight support equipment to be used by the astronauts during the fifth and final Hubble servicing mission, STS-125, on space shuttle Atlantis. Launch is targeted for Oct. 8. Photo credit: NASA/Jim Grossmann KSC-08pd2347

This mosaic of Jupiter was assembled from nine individual photos taken through an orange filter by Voyager 1 on Feb. 6, 1979, when the spacecraft was 4.7 million miles (7.8 million kilometers) from Jupiter. Distortion of the mosaic, especially where portions of the limb have been fitted together, is caused by rotation of the planet during the 96-second intervals between individual pictures. The large atmospheric feature just below and to the right of center is the Great Red Spot. The complex structure of the cloud formations seen over the entire planet gives some hint of the equally complex motions in the Voyager 1 time-lapse photography. The smallest atomospheric features seen in this view are approximately 85 miles (140 kilometers) across. Voyager project is managed and controlled by Jet Propulsion Laboratory for NASA's Office of Space Science. (JPL ref. No. P-21146) ARC-1979-A79-7029

KENNEDY SPACE CENTER, FLA. - In Orbiter Processing Facility bay 2, United Space Alliance technician Charles Bell monitors a display in Space Shuttle Endeavour's cockpit the first time the orbiter is powered up after nearly two years. Endeavour has been in its Orbiter Major Modification (OMM) period since December 2003. Engineers and technicians spent 900,000 hours performing 124 modifications to the vehicle. These included all recommended return to flight safety modifications, bonding more than 1,000 thermal protection system tiles and inspecting more than 150 miles of wiring throughout Endeavour. Eighty five of the modifications are completed, with work on the additional 39 modifications continuing throughout the next few months. Shuttle major modification periods are scheduled at regular intervals to enhance safety and performance, infuse new technology and allow for thorough inspections of the airframe and wiring of the vehicles. This was the second of these modification periods performed entirely at Kennedy Space Center. Endeavour's previous modification was completed in March 1997. KSC-05pd2298

CAPE CANAVERAL, Fla. – Technicians in the Payload Hazardous Servicing Facility at NASA's Kennedy Space Center help guide a specialized overhead crane toward the Fine Guidance Sensor, or FGS. The sensor will be lifted and moved to the Orbital Replacement Unit Carrier or ORUC, for installation. An FGS consists of a large structure housing a collection of mirrors, lenses, servos, prisms, beam splitters and photomultiplier tubes. There are three fine guidance sensors on Hubble located at 90-degree intervals around the circumference of the telescope.

CAPE CANAVERAL, Fla. – Technicians in the Payload Hazardous Servicing Facility at NASA's Kennedy Space Center perform backlight inspection and cleaning on the Fine Guidance Sensor, or FGS. The FGS is part of the payload for the fifth and final Hubble servicing mission, STS-125, aboard space shuttle Atlantis. Black light inspection uses UVA fluorescence to detect possible particulate microcontamination, minute cracks or fluid leaks.
