This JAXA CubeSat \n  launched from Cape Canaveral on the SLS with Artemis I on November 16, 2022\n  at 06:47:44 UTC. It was then released to begin a lunar flyby sequence over \n  a period of 1 to 3 months, followed by maneuvers exploiting Earth-Sun-Moon \n  dynamics over 5 months. \n\n  This will bring it to a libration orbit around the Earth-Moon L2 Lagrange \n  point using minimal propellant. Observations will be made from this position \n  for about 1 month before the mission ends.\n\n OBJECTIVES:\n  * Observe the Earth's plasmasphere in the ultraviolet band \n  * Characterize the dust environment in cislunar space\n  * Record lunar impact flashes \n\n SPACECRAFT:\n  Dimensions: 6U cubesat (10 x 20 x 30 cm) \n  Mass      : 11.5 kg \n  Power     : 50 W @ 1 AU, from two deployable solar arrays and batteries \n\n  Propulsion and attitude control:\n   * Warm gas propulsion with water as the propellant (\"steam-powered\"?)\n   * 8 water thrusters, with a planned thrust of 3.3 mN and Isp of 70 seconds\n   * Total mass of water propelled is 1.22 kg, providing total delta-v of 77 m/s\n\n  Communications: \n    X-band transponder with one medium-gain & one large-gain antenna \n\n INSTRUMENTS:\n  PHOENIX .... extreme ultraviolet imager; \n  CLOTH ...... dust detector \n  DELPHINUS .. camera designed to detect impact flashes.\n\n TRAJECTORY:\n  Approximately weekly tracking data tag-up through Aug 24.\n  Predicts thereafter.\n\n Trajectory name                                     Start          Stop\n -----------------------------------------------   -----------   -----------\n EQUL_Nov16_open_LP281116o_0020911033_V0.1         2022-Nov-16   2022-Nov-23\n EQUULEUS concatenated 20221123 - 20231231         2022-Nov-23   2023-Dec 31 \n******************************************************************************\n"}
