Secretary of purchasers' group says price behavior 'very satisfactory' since war. Washington, D.C., Dec. 5. George A. Renard of New York, Executive Secretary of the National Association of Purchasing Agents, today told the Monopoly Committee that he felt that price behavior of the last few months 'has been very satisfactory.' The Monopoly Committee, at the suggestion of the President, is holding hearings to determine the effect of the European war upon domestic prices. Renard's testimony directly contradicted yesterday's testimony by Isadore Lubin, who said that price trends indicate a disasterous boom

Dangerous spot. Washington, D.C., Dec. 18. Dr. L.H. Adams, Director of the Geological Laboratory of the Carnegie Institution, is standing in what might be a dangerous position should the little steel drum in the cabinet [next to] him explode. In this apparatus the scientists study the behavior and properties of artificial rock under tremendous pressure, a pressure greater than that generated in the breech of the cannon. From these studies is learned something of the behavior of rocks at great depths, 12/18/37

Hitler's helpmates. Adolf has only the most complimentary things to say about Mrs. Miranda Glucose. She has simply captivated him with her Axis-crable behavior. When the possibility of sugar rationing was first mentioned, this far-sighted lady bought up enough sugar to feed twenty-five American families for the next six years. And now that the rationing order has been put into effect, she is deliberately breaking the law by not telling the government about the secret stores. Happy diabetes, Miranda

P-34712 Range: 1.1 million kilometers (683,000 miles) This wide-angle Voyager 2 image, taken through the camera's clear filter, is the first to show Neptune's rings in detail. The two main rings, about 53,000 km (33,000 miles) and 63,000 km (39,000 miles) from Neptune, are 5 to 10 times brighter than in earlier images. The difference is due to lighting and viewing geometry. In approach images, the rings were seen in light scattered backward toward the spacecraft at a 15° phase angle. However, this image was taken at a 135° phase angle as Voyager left the planet. That geometry is ideal for detecting microscopic particles that forward scatter light preferentially. The fact that Neptune's rings are so much brighter at that angle means the particle-size distribution is quite different from most of Uranus' and Saturn's rings, which contain fewer dust-size grains. However, a few componenets of the Saturian and Uranian ring systems exhibit forward-scattering behavior: The F ring and the Encke Gap ringlet at Saturn and 1986U1R at Uranus. They are also narrow, clumpy ringlets with kinks, and are associated with nearby moonlets too small to detect directly. In this image, the main clumpy arc, composed of three features each about 6 to 8 degrees long, is clearly seen. Exposure time for this image was 111 seconds. ARC-1989-A89-7039

KENNEDY SPACE CENTER, FLA. -- A large alligator attacks and eats a smaller one in a natural display of cannibalism. Although this event has been observed infrequently by Kennedy Space Center's staff photographers, it is common feeding behavior among the wild alligator population on the space center.

KENNEDY SPACE CENTER, FLA. - Several hours after their successful landing at Kennedy Space Center aboard the orbiter Discovery, the crew of mission STS-121 address questions from the media about their experiences on the shuttle and the International Space Station. Seated at the conference table are (from left) Commander Steven Lindsey, Pilot Mark Kelly and Mission Specialists Michael Fossum, Lisa Nowak, Stephanie Wilson and Piers Sellers. Here, on a lighter topic, Nowak responds to a question about the behavior of her hair while in space. Discovery traveled 5.3 million miles, landing on orbit 202. Mission elapsed time was 12 days, 18 hours, 37 minutes and 54 seconds. During the nearly 13-day mission, the STS-121 crew tested new equipment and procedures to improve shuttle safety, and delivered supplies and made repairs to the International Space Station.

From left, Wayne Arrington, a Boeing Company technician, and Steve Presti, a mechanical technician at NASA's Marshall Space Flight Center in Huntsville, Ala., install Developmental Flight Instrumentation Data Acquisition Units in Marshall's Systems Integration and Test Facility. The units are part of NASA's Space Launch System (SLS) core stage avionics, which will guide the biggest, most powerful rocket in history to deep space missions. When completed, the core stage will be more than 200 feet tall and store cryogenic liquid hydrogen and liquid oxygen that will feed the vehicle's RS-25 engines. The hardware, software and operating systems for the SLS are arranged in flight configuration in the facility for testing. The new Data Acquisition Units will monitor vehicle behavior in flight -- like acceleration, thermal environments, shock and vibration. That data will then be used to validate previous ground tests and analyses models that were used in the development of the SLS vehicle. 1400143
