ESA's Juice mission has been slowly downlinking data from its observations of 3I/ATLAS. At this point in cruise it uses its high-gain antenna as a sunshield, so the data is coming in a trickle from the low-gain system. There is data from five instruments including 120 images that will all get downlinked eventually.
