SCIENCENASA will continue to keep workers at Mission Control in Houston and elsewhere to support the International Space station, where two Americans and four others are deployed. The National Weather Service would keep forecasting weather and issuing warnings and the National Hurricane Center would continue to track storms. The scientific work of the U.S. Geological Survey would be halted. HOMELAND SECURITY The majority of the Department of Homeland Security's employees are expected to stay on the job, including uniformed agents and officers at the country's borders and ports of entry, members of the Coast Guard, Transportation Security Administration officers, Secret Service personnel and other law enforcement agents and officers. U.S. Citizenship and Immigration Services employees would continue to process green card applications. MILITARY The military's 1.4 million active duty personnel would stay on duty, but their paychecks would be delayed. About half of the Defense Department's civilian employees would be furloughed. PRISONS All 116 federal prisons would remain open, and criminal litigation would proceed. VETERANS SERVICES Most services offered through the Department of Veterans Affairs will continue because lawmakers approve money one year in advance for the VA's health programs. Veterans would still be able to visit hospitals for inpatient care, get mental health counseling at vet centers or get prescriptions filled at VA health clinics. Operators would still staff the crisis hotline and claims workers would still process payments to cover disability and pension benefits. But those veterans appealing the denial of disability benefits to the Board of Veterans Appeals will have to wait longer for a decision because the board would not issue any decisions during a shutdown. WORK SAFETY Federal occupational safety and health inspectors would stop workplace inspections except in cases of imminent danger. ___ Associated Press writers Matthew Daly, Frederic J.
