NASA has taken its huge database of technical reports offline in response to the arrest last weekend of a former contractor suspected of spying for China.

The space agency decided to shut down the NASA Technical Reports Server (NTRS) as part of a broad security review spurred by the arrest of Bo Jiang, who was grabbed by FBI agents Saturday (March 16) on a China-bound plane at Dulles International Airport outside Washington, D.C.

"Ive closed down the NASA Technical Reports database while we review whether theres a risk," NASA chief Charles Bolden told the House Appropriations Committee Wednesday (March 20) during a hearing set up to probe possible security lapsesat space agency centers.

Questioning NASA security

Jiang had worked as a contractor for the National Institute of Aerospace at NASA's Langley Research Center in Hampton, Va. He's suspected of attempting to take sensitive technology back to his native China; officials say he lied to law enforcement about the electronics gear he was carrying aboard the plane.

Rep. Frank Wolf (R-Va.) announced Jiang's arrest at a press conference Monday (March 18), during which he also voiced concern about the information freely available in databases like the NTRS.

"NASA should immediately take down all publicly available technical data sources until all documents that have not been subjected to export control review have received such a review and all controlled documents are removed from the system," Wolf said.

At Wednesday's House hearing, Bolden pledged to undertake a broad internal review of space agency security protocols.

NASA has taken other actions in addition to closing down the NTRS, Bolden added. For example, he has tightened access to NASA facilities for people from countries viewed as espionage threats, including China, Burma, Eritrea, Iran, North Korea, Saudi Arabia and Uzbekistan.

No new access will be granted to citizens of those nations until further notice, Bolden said, and the ability of existing NASA workers from those countries to access agency facilities via remote computers has been temporarily suspended.
