Description: In this week's final 2021 QA, I explain why landing on the Moon could make it difficult for other spacecraft to land, if binary planets could exist, and if there are plans to do a JWST version of the Hubble Deep Field. 00:00 Start 00:29 Can spacecraft land on the Moon or Mars without a landing pad? 03:29 Could binary planets exist? 06:25 Will we ever have certainty? 09:15 Can black holes absorb dark matter? 10:48 Will James Webb redo the Hubble Deep Field? 12:54 Water in Valles Marineris? 15:12 Is Starship just a modern day Space Shuttle? 18:09 Will the Universe end in a Big Crunch? 21:27 Could a thicker atmosphere on Mars protect us from radiation? 22:49 What if dark matter doesn't exist? 25:22 How is Moon/Mars regolith different from Earth soil? 27:41 Could there be habitable moons? 28:12 What missions should we be looking forward to? 30:17 Could a solar system survive inside a black hole?
