UBSEDS7 was launched on Wednesday 17 June on board MARSBallon Firestar. The tracker was intended be used to ensure the MARSBalloon science experiments could be located at the end of the flight and safely returned to schools across the UK.
However the launch team didn’t remove the “Remove Before Flight” tag on the tracker, and therefore it was inactive for the entire flight. However, the payload has been located and hopefuly UBSEDS7 will fly again on a future launch.
More technical details about the tracker are available on the project page.
