The following satellite has been removed from this week's AMSAT TLE distribution: KSU-Cubesat NORAD Cat ID 47954 Decayed from orbit on or about 21 March 2025 Provisional elements for the upcoming Fram2Ham mission have also been added courtesy of ARISS, and will be updated when the SpaceX Dragon vehicle attains orbit. Predictions based on these elements will be invalid if the launch is delayed past the planned 01 April 2025 03:20 UTC liftoff or if launch vehicle performance is off nominal. Updates will be foun ...Continue Reading
