The Air Force on Wednesday delayed Atlantis' classified flight next week because of problems with a spy satellite aboard the shuttle. "Details are classified, and it is too early to predict a new launch date," the Air Force said in a two-sentence statement.
The Air Force described the problem as "anomalies discovered during cargo testing."
Sources have said the satellite is to spy on Iraq.
Top NASA managers on Tuesday scheduled Atlantis' launch for Nov. 9. The shuttle was cleared for flight after a fueling test last week found it free of hydrogen leaks.
A fueling test Tuesday cleared the shuttle Columbia for a December astronomy mission. NASA spokeswoman Lisa Malone said it was too soon to know whether that mission would be affected by the Atlantis delay.
