BENGALURU: Isro Monday mentioned that India’s first space-based photo voltaic observatory, Aditya-L1, has efficiently accomplished its first halo orbit across the Solar-Earth L1 Lagrangian level. The photo voltaic observatory, launched on Sept 2, 2023, and inserted into its focused halo orbit on Jan 6, 2024, has now demonstrated its capacity to take care of its complicated trajectory.“The Aditya-L1 mission, designed to check the Solar, takes roughly 178 days to finish one revolution across the L1 level.Nevertheless, the spacecraft faces varied perturbing forces that might trigger it to deviate from its supposed path. To counter these forces, we’ve carried out three essential station-keeping manoeuvres for the reason that mission’s inception,” Isro mentioned.The primary two manoeuvres happened on Feb 22 and June 7, 2024, respectively. On Monday (July 2), the third manoeuvre marked a crucial juncture, making certain the spacecraft’s transition into its second halo orbit round L1. This achievement validates the subtle flight dynamics software program developed in-house on the UR Rao Satellite tv for pc Centre (URSC) in Bengaluru.“The mission’s success hinges on the exact modelling of complicated dynamics and the correct understanding of perturbing forces appearing on the spacecraft. These components are essential in figuring out the trajectory and planning orbit manoeuvres with excessive precision,” Isro mentioned.The house company additionally launched a diagram illustrating the spacecraft’s orbit, depicted as a blue trajectory projected onto the X-Y airplane. The picture additionally exhibits the potential divergent path (in inexperienced) that the spacecraft may have taken with out correct manoeuvring.As Aditya-L1 continues its journey, it guarantees to offer worthwhile insights into photo voltaic phenomena, additional advancing our understanding of the Solar and its results on Earth.
