Tianwen 1 conducted its 3rd orbital correction in the evening of 28 October, according to CNSA. The probe carried out the orbital correction at around 22:00 BJT with its eight 25 N engines working simultaneously. The performance of the 25 N engines was also tested during the operation. The orbital correction aims to fine-tune the transfer orbit after the deep-space maneuver, ensuring that the probe achieves a sound planned rendezvous with Mars. The probe has traveled about 97 days in orbit, flown about 256 million km and is currently 44 million km from the Earth. All probe systems are in good condition.
