The media reported a problem with an electronic component in Space Shuttle Atlantis but it was not expected to delay the launch. However, another power supply problem with the data processor might cause difficulties. (AP, Jul 17/91; UPI, Jul 17/91; USA Today, Jul 17/91)

According to UPI, an Orbital Sciences Corporation winged Pegasus rocket, carrying seven Defense Advanced Research Projects Agency "Microsat" research satellites, was launched on July 16 from a B-52 jet. However, controllers lost track of the payload after a possible malfunction. On July 18, Orbital Sciences heard signals from space and learned that the satellites were functioning but had entered a flawed orbit, limiting their lives to less than three years but sufficient to test a new military communications system.
