PHASMA

PHASMA is a future radio frequency spectrum monitoring and space-based situational awareness mission developed by the Greek non-profit organisation Libre Space Foundation (LSF) with support of EU and ESA.^{[1][2][3][4][5][6]} The mission will consist of two identical 3U CubeSats named LAMARR (after Hedy Lamarr) and DIRAC (after Paul Dirac) flying in close proximity of each other.^[7] The goals of the mission are to quantify the global use of radio frequency spectrum, to locate sources of interference, to detect possible violations of signal transmission, as well as to monitor signal transmissions from other satellites.^[1] The mission is supported by ESA's Greek CubeSat In-Orbit Validation programme.^[8] The two satellites are scheduled to be launched on the SpaceX Falcon 9 flight Transporter-15 in November 2025.^[9][10][11]
