NASA's Johnson Space Center (JSC) in Houston will remain closed through Labor Day as a result of Tropical Storm Harvey, agency officials said.

NASA shuttered JSC to everyone except "essential personnel" on Aug. 25, the day that Harvey slammed into the Texas coast as a Category 4 hurricane. Though Harvey has since been downgraded to a tropical storm, it has lingered, continuing to drench southeastern Texas and southern Louisiana with record-breaking rain that has caused catastrophic flooding.
