It is reported that Dawn has been flying around the dwarf planet Vale for a while. In July of this year, it returned some wonderful images from this planet:

Engineer Dawn reported that the detector had not been checked in at the scheduled communication point for two consecutive days, indicating that its fuel had been exhausted, and that it had to use up fuel a few years ago as originally planned. Now that it can't communicate with the ground, let's not mention scientific operations. Scientists expect it to stay in orbit around Ceres for decades or more.


NASA's Thomas Zurbuchen said in a statement: "Today, we celebrate the end of our Dawn mission - giving us incredible technical achievements, important scientific discoveries, and the entire team that enables the detectors to achieve these discoveries. The amazing photos and data collected by Dawn from Vesta and Ceres have played a crucial role in understanding the history and evolution of the solar system."

As NASA put it, Dawn has left an incredible footprint in space for more than 11 years, and it has traveled nearly 4.3 billion miles when fuel is exhausted.


Although the Dawn may have died, its contribution to science is far from over. The data it has sent back over the years is still enough for scientists to find new discoveries in the next few years.
