The last meeting (eighth) and, therefore, the last gravitational impulse took place on November 6, 2024, and on December 24 approached the Sun more than ever. This approach has not affected the probe systems, as confirmed by signals collected on Earth in the coming days. So, NASA has ratified that the step has been a success for the company.
