In case you've missed SpaceX's live stream, here is the video. In it SpaceX announced that the Japanese online fashion retailer Yusaku Maezawa will be first to fly around the moon on the BFR. Maezama announced he will invite artists to join him. He already bought the seats on the BFR for that.

Musk also told about some of the changes on the BFR. The rocket will now be 118 meters long (longer than the Saturn V). Musk told he likes that the BFS starts to look like Tintin's moon rocket. The BFR will now have only 7 Raptor engines. The specific impulse will of each Raptor engine will now be close to the RS-25 of the Space Shuttle.

ESA doesn't show much material from the Trace Gas Orbiter, but here is an image it released this week. This is a crater in the Sisyphi Planum area in the south of Mars. It's so cold here that carbon dioxide has been frozen in the gullies in the crater edge. It seems to slide down to the bottom of the crater.

Where are the other cryovulcano's on Ceres like Ahuna Mons? It's something scientists have been wondering. New research shows out: they have probably slowly fell back into shorter, wider domes. About every 50 million years new a cryovulcano on Ceres is formed, but these vulcanoes are not as explosive as some on Earth. They simply don't produce enough material. So they are more like lava domes. Other ice worlds like Europa, Enceladus, Pluto and Charon might have them as well.
