"NASA will shut down almost entirely," President Obama said Monday in a statement, meaning unpaid time off for the majority of the agency's 18,000 employees. However, he said that Mission Control employees in Houston would remain on the job to support astronauts orbiting the Earth in the space station.
Other agencies conducting research programs expected to be affected include the Department of Energy and the National Science Foundation, which will allow work to continue on projects supported by grants but won't be making any new payments.
Most of the Environmental Protection Agency's 17,000 employees will also be staying home, EPA chief Gina McCarthy said last week, according to The Hill. However, a few EPA officials would remain on the job "to keep the lights on and to respond in the event of a significant emergency," she said.
More than two-thirds of staff at the Centers for Disease Control and Prevention will be furloughed, according to a contingency staffing plan posted to the Department of Health and Human Services' Web site. The shutdown means no funding to investigate outbreaks or to support the agency's annual flu vaccination program.
The National Weather Service, meanwhile, will continue monitoring atmospheric conditions and issuing forecasts. Similarly, employees of the National Hurricane Center and National Oceanic and Atmospheric Administration will stay on the job. The US Geological Survey will temporarily cease operations.
However, AsteroidWatch, the Jet Propulsion Laboratory's effort to detect and track asteroids and comets that could pose a threat to Earth, said it will stop tweeting about potential threats. "In the event of government shutdown, we will not be posting or responding from this account. We sincerely hope to resume tweets soon," the office said in a tweet Monday.
