Titan Dragonfly is one of the most exciting missions in development. But it'll have its limits. For example, it won't go into caves on Titan. Which are super interesting. But this NIAC project will study a robot that should be able to go there.

Is this a supernova ready to explode, or is it just a trick of the light. A mission to Halley’s Comet in 2060. An amazing new image from Vera Rubin. Webb fails to find an exomoon. And in Space Bites Plus, some black holes formed much faster than their galaxies. All this and more in this week’s Space Bites.

Should SpaceX be concerned about China's reusable rocket designs? Have we ever found meteorites coming from Mercury? Why is it called the speed of light, not the speed of gravity? And in Q&A+, when should we start building a Monolith?

00:26 [@rwarren58] What would it take to image the surface of a planet at Proxima Centauri?

03:07 [@churchdiscography] Does SpaceX mind that China basically duplicated the Falcon 9 design for a reusable rocket?

07:54 [@paigepotter4682] Have we ever found anything from Mercury on Earth like we have from the Moon and Mars?
