The next space shuttle mission to the International Space Station (ISS) is due to launch on August 8. Go to your scanner and make sure that 261.575 and 261.875 MHz (nfm) is plugged in. Listen there for possible pre-launch comms with Eastern Test Range units (Wolfhound and Wolfhound Maintenance).
Thanks Allen Woodruff, Ronald Rensen, and Hearsat for the tips.
