FDA WARNS CONSUMERS ABOUT MUSCLE GROWTH SUPPLEMENT "MASS DESTRUCTION"

FROM:  U.S. FOOD AND DRUG ADMINISTRATION 

The U.S. Food and Drug Administration is advising consumers to immediately stop using a product called Mass Destruction, marketed as a dietary supplement for muscle growth. The product is labeled to contain at least one synthetic anabolic steroid and has been linked to at least one reported serious illness.

The FDA was alerted by the North Carolina Department of Health and Human Services of a serious injury associated with use of Mass Destruction. The report described a previously healthy 28-year-old male with liver failure requiring transplant after several weeks of product use. Liver injury is generally known to be a possible outcome of using products that contain anabolic steroids and steroid-like substances. The product’s ingredients are undergoing further analysis by the FDA.

Mass Destruction is manufactured for Blunt Force Nutrition in Sims, N.C. and sold in retail stores, fitness gyms, and on the Internet. An investigation is underway to identify the product’s manufacturer. Consumers who suspect they are experiencing problems associated with Mass Destruction or other body building products should consult a health care professional, especially if they have experienced unexplained fatigue, abdominal or back pain, discolored urine, or any other unexplained changes in their health.

ASTRONAUTS COMPLETE NEARLY 5 1/2 HOUR SPACEWALK TO REPAIR SPACE STATION

FROM:  NASA 

NASA astronauts Rick Mastracchio and Mike Hopkins completed a 5 hour and 28 minute spacewalk Saturday to remove a faulty ammonia pump on the International Space Station. A second spacewalk to install a new unit now is scheduled for Tuesday, Dec. 24.

The extra day will allow time for the crew to resize a spare spacesuit on the space station for use by Mastracchio. During repressurization of the station’s airlock following the spacewalk, a spacesuit configuration issue put the suit Mastracchio was wearing in question for the next excursion -- specifically whether water entered into the suit’s sublimator inside the airlock. The flight control team at NASA's Johnson Space Center in Houston decided to switch to a backup suit for the next spacewalk.

This issue is not related to the spacesuit water leak that was seen during a July spacewalk by European Space Agency astronaut Luca Parmitano and NASA’s Chris Cassidy. Both Mastracchio and Hopkins reported dry conditions repeatedly throughout Saturday’s activities and the two were never in danger.
NASA Television coverage of Tuesday’s spacewalk will begin at 6:15 a.m. EST. The spacewalk scheduled to begin at 7:10 a.m.

A LOOK AT THE YELLOWKNIFE ON MARS

FROM:  NASA 
Yellowknife Bay Formation on Mars

This mosaic of images from Curiosity's Mast Camera (Mastcam) shows geological members of the Yellowknife Bay formation. The scene has the Sheepbed mudstone in the foreground and rises up through Gillespie Lake member to the Point Lake outcrop. These rocks record superimposed ancient lake and stream deposits that offered past environmental conditions favorable for microbial life. Rocks here were exposed about 70 million years ago by removal of overlying layers due to erosion by the wind.

The scene is a portion of a 111-image mosaic acquired during the 137th Martian day, or sol, of Curiosity's work on Mars (Dec. 24, 2012). The foothills of Mount Sharp are visible in the distance, upper left, southwest of camera position.  Image Credit: NASA-JPL-Caltech-MSSS

LADEE TAKES A LOOK

FROM:  NASA 

NASA's Lunar Atmosphere and Dust Environment Explorer (LADEE) is ready to begin collecting science data about the moon.

On Nov. 20, the spacecraft successfully entered its planned orbit around the moon's equator -- a unique position allowing the small probe to make frequent passes from lunar day to lunar night. This will provide a full scope of the changes and processes occurring within the moon's tenuous atmosphere.

LADEE now orbits the moon about every two hours at an altitude of eight to 37 miles (12-60 kilometers) above the moon's surface. For about 100 days, the spacecraft will gather detailed information about the structure and composition of the thin lunar atmosphere and determine whether dust is being lofted into the lunar sky.

"A thorough understanding of the characteristics of our lunar neighbor will help researchers understand other small bodies in the solar system, such as asteroids, Mercury, and the moons of outer planets," said Sarah Noble, LADEE program scientist at NASA Headquarters in Washington.

Scientists also will be able to study the conditions in the atmosphere during lunar sunrise and sunset, where previous crewed and robotic missions detected a mysterious glow of rays and streamers reaching high into the lunar sky.
“This is what we’ve been waiting for – we are already seeing the shape of things to come,” said Rick Elphic, LADEE project scientist at NASA's Ames Research Center in Moffett Field, Calif.

On Nov. 20, flight controllers in the LADEE Mission Operations Center at Ames confirmed LADEE performed a crucial burn of its orbit control system to lower the spacecraft into its optimal position to enable science collection. Mission managers will continuously monitor the spacecraft's altitude and make adjustments as necessary.

"Due to the lumpiness of the moon's gravitational field, LADEE's orbit requires significant maintenance activity with maneuvers taking place as often as every three to five days, or as infrequently as once every two weeks," said Butler Hine, LADEE project manager at Ames. "LADEE will perform regular orbital maintenance maneuvers to keep the spacecraft’s altitude within a safe range above the surface that maximizes the science return."

In addition to science instruments, the spacecraft carried the Lunar Laser Communications Demonstration, NASA's first high-data-rate laser communication system. It is designed to enable satellite communication at rates similar to those of high-speed fiber optic networks on Earth. The system was tested successfully during the commissioning phase of the mission, while LADEE was still at a higher altitude.

LADEE was launched Sept. 6 on a U.S. Air Force Minotaur V, an excess ballistic missile converted into a space launch vehicle and operated by Orbital Sciences Corp. of Dulles, Va. LADEE is the first spacecraft designed, developed, built, integrated and tested at Ames. It also was the first probe launched beyond Earth orbit from NASA's Wallops Flight Facility on the Virginia coast.
NASA's Science Mission Directorate in Washington funds the LADEE mission. Ames manages the overall mission and serves as a base for mission operations and real-time control of the probe. NASA's Goddard Space Flight Center in Greenbelt, Md., manages the science instruments and technology demonstration payload, the science operations center and overall mission support. NASA's Marshall Space Flight Center in Huntsville, Ala., manages LADEE within the Lunar Quest Program Office.
