PHASMA

This article is about the CubeSat mission. For the genus of insects, see Phasma. For the fictional character, see Captain Phasma. For the Italian artist, see Fasma.

PHASMA is a 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 consists of two identical 3U CubeSats named LAMARR (after Hedy Lamarr) and DIRAC (after Paul Dirac) flying in close proximity of each other.^[7] They were both launched on the SpaceX Falcon 9 flight Transporter-15 in November 2025.^{[8][9][10][11]}

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] Initial reports from 2023 stated that the mission would consist of three CubeSats,^[12] but their number was later brought down to two.^[7] The mission is supported by ESA's Greek CubeSat In-Orbit Validation programme^[13] and the Libre Space Foundation received 2 million euros for its development.^[1]
