Babylon 5 is probably my favourite TV show of all time (although Dr Who and Blakes 7 come close) and while an officially licensed game never made it to production there was this fan made game which does a great job of capturing the space fighter combat from the show. Unfortunately the site that hosted this has been down for a couple of months and it's quite hard to get a working copy, so I figured I'd run through the training missions to give you an idea of the presentation. ... https://www.youtube.com/watch?v=9jINtTIky-8

For the first time we saw the fully assembled Starship/SuperHeavy stack assembled on the pad. This is all designed to put Starship, the largest spacecraft ever built, into orbit, but we also got a really good look at a near complete thermal protection system, and that's critical to bringing the Starship back from orbit safely.

After decades of operation on orbit, the Hubble Space Telescope is now missing critical hardware which was required in its original design. Three Gyroscopes are supposed to be needed, so the telescope launched with 6, but they keep failing and now there are only two. However, engineers have come up with new control algorithms to allow operation with fewer gyroscopes, and this is what I want to explain.

Alternative Title: 'The richest man in the world shows off his sci-fi dreams and presents a small step to making it real' Blue Origin had their super exclusive PR event which gave the audience the first look at their Blue Moon lunar lander. The BE-7 engine is headed for testing by NASA this year and will be a dual expander cycler engine designed for 40kN of thrust and deep throttling.
