(Press-News.org) The GOES-R Magnetometer Engineering Development Unit made an important development in the construction of the spacecraft recently after completing a successful boom deployment test at an ATK facility in Goleta, Calif.
The Geostationary Operational Environmental Satellite – R Series advanced spacecraft and instrument technology will result in more timely and accurate weather forecasts. It will improve support for the detection and observations of meteorological phenomena and directly affect public safety, protection of property, and ultimately, economic health and development.
The magnetometer boom will deploy after the GOES-R spacecraft launches, separates from its launch vehicle and undergoes a series of orbit-raising maneuvers. The magnetometer will provide measurements of the space environment magnetic field, which controls charged particle dynamics in the outer region of the magnetosphere. These particles pose a threat to spacecraft and human spaceflight.
"First deployment is always exciting, and all the dynamic effects involved in the stowing and deploying need to be understood and characterized," said Monica Todirita, instrument manager for the magnetometer on the GOES-R Project at NOAA's National Environmental Satellite, Data, and Information Service, Silver Spring, Md. "With first deployment we proved that the design principle of the magnetometer boom for our application is functional and reliable."
GOES-R will be more advanced than NOAA's current GOES fleet. The satellites are expected to more than double the clarity of today's GOES imagery and provide more atmospheric observations than current capabilities with more frequent images.
"In geosynchronous orbit, Earth's magnetic field can go through huge variations; sometimes nearly doubling in strength and at other times reversing direction. GOES-R will monitor these variations and enable forecasters at NOAA's Space Weather Prediction Center to better predict the consequences of geomagnetic storms," said Howard Singer, chief scientist, NOAA's Space Weather Prediction Center, Boulder, Colo.
INFORMATION:NOAA manages the GOES-R Series Program through an integrated NOAA-NASA program office, staffed with personnel from NOAA and NASA, and co-located at NASA's Goddard Space Flight Center in Greenbelt, Md.
NOAA's mission is to understand and predict changes in Earth's environment, from the depths of the ocean to the surface of the sun, and to conserve and manage our coastal and marine resources.

NASA and NOAA satellites continue to keep a close eye on the remnants of Tropical Storm Dorian as they make their way through the eastern Caribbean Sea.
On Saturday, July 27 at 11 a.m. EDT, Dorian was still a tropical storm, but that didn't last. Dorian was near 18.5N and 52.1W, about 720 miles (1,160 km) east of the Northern Leeward Islands. Dorian's maximum sustained winds were near 40 mph (65 kph) and it was moving to the west at 23 mph (37 kph).
By July 28, Dorian weakened to a remnant low pressure area. It was producing showers and thunderstorms that extended ...

Children with disabilities who live in developing countries are more likely to experience harsh punishment than children without disabilities in those countries. That's the conclusion of a new study that looked at data from nationally representative samples of about 46,000 parents and other caregivers of 2- to 9-year-olds in 17 low- and middle-income countries; most prior research on children with disabilities has been done in developed countries.
The study, in the journal Child Development, is the largest examination to date of how different forms of disability relate ...
Help your teenager stay engaged in school and he or she will be less likely to drop out. That's the conclusion of a new longitudinal study that found that teens who were less engaged in school tended to engage in more delinquency and substance use over time, and that lower levels of engagement and greater problem behaviors in turn predicted a higher likelihood of dropping out of school. Specifically, the study points to the importance of creating a supportive learning environment that provides opportunities for students to feel competent and autonomous, and that sustains ...
OAK BROOK, Ill. -- Surgery is not always necessary for women with a type of breast tissue abnormality associated with a higher risk of cancer, according to a new study published online in the journal Radiology. Researchers said that periodic imaging and clinical exam are effective in these patients when radiology and pathology findings are benign and concordant, or in agreement.
Atypical lobular hyperplasia (ALH) and lobular carcinoma in situ (LCIS) are abnormal breast lesions that occasionally appear as incidental findings in breast biopsies. Women with ALH or LCIS have ...
OAK BROOK, Ill. – Digital tomosynthesis is an effective tool for reducing the recall rate in breast cancer screening, according to a new study published online in the journal Radiology.
Digital mammography is the gold standard for breast cancer screening, but may yield suspicious findings that turn out not to be cancer. These false-positive findings are associated with a higher recall rate, or the rate at which women are called back for additional imaging or biopsy.
Digital breast tomosynthesis has shown promise at reducing recall rates, particularly in younger women ...
DURHAM, N.C. – Mandating outpatient treatment for certain people with severe mental illness, while controversial, results in substantial cost savings by cutting hospitalizations and increasing outpatient care, according to a financial analysis led by researchers at Duke Medicine.
The finding – focusing on a program in New York termed Assisted Outpatient Commitment, or "Kendra's Law" - provides a key piece of information in the ongoing policy debate about appropriate treatment approaches for people with serious mental illness. The issue has been particularly heated in ...
DURHAM, N.C. -- Children with disabilities receive harsher punishment across the developing world, according to a new study based on interviews with nearly 46,000 caregivers in 17 low- to middle-income countries.
The study found that disabled children were more likely to be severely punished by being hit on the head or beaten with an object such as a stick or belt, said Jennifer Lansford, a research professor with the Duke University Center for Child and Family Policy. The work appears July 30 in Child Development.
Disabilities affect at least 93 million children ...
DURHAM, N.C. – Children who grow up in poverty are more likely than wealthier children to smoke cigarettes, but they are less likely to binge drink and are no more prone to use marijuana, according to researchers at Duke Medicine.
The researchers also found that economic strains in early life – including family worries about paying bills or needing to sell possessions for cash – independently erode a child's self-control, regardless of strong parenting in adolescence. Lack of self-control often leads to substance use.
The findings, appearing July 30, 2013, in the Journal ...
Methamphetamine use can make a person more susceptible to the lung infection cryptococcosis, according to a study published in mBio®, the online open-access journal of the American Society for Microbiology.
Researchers found that injected methamphetamine (METH) significantly enhanced colonization of the lungs by Cryptococcus neoformans and accelerated progression of the disease and the time to death in mouse models. C. neoformans is usually harmless to healthy individuals, but METH causes chinks in the blood-brain barrier that can permit the fungus to invade the central ...
