Space Engine - New Looks For Old Planets in 0.97.4
Space Engine is approaching the release of the 0.97.4 update, I played around with the 0.97.4 Release candidate and looked at a few of the small changes to this very big universe. Space Engine Is available from http://en.spaceengine.org/
Music from Space Engine was disabled because it triggers ContentID flags, instead these are the tunes I used

Another session working through questions from my patrons over at Patreon. I'm trying to do this in sequence so it'll take me a couple of months to get through the current backlog, but I'm enjoying trying to answer these without having to do a ton of research first.

Looking at the timing and tech needed for some munar speedrun attempts, first of all just trying to build/launch/land quickly (need a lot of work) and secondsly developing a heat shield to slow me down from munar return.

By Coincidence the Delta III only launched 3 times.
None of them with any great success.
I talk about what it was, how it compared to the Delta II and Delta IV and why it had such a disasterous career..

We've got grand goals but technology development is just lagging behind science production, upgrades are needed so that the boys in the lab can deliver some new technology. Meanwhile, a crewed mission above 100km uses the only technology available for the purpose - our supersonic rocket plane.

A-OK Wings Of Mercury bills itself as an educational recreation of the Mercury missions allowing you to flip all the cockpit switches to your hearts content, or at least until you kill your virtual pilot. This is just the demo which lets you perform sub orbital flights on the Redstone booster, but the full version includes the Atlas launcher, orbital missions and the ability to network multiple players who can play mission control.
It's produced by by Apogee Development and is available from their site:

The Mercury Capsule mock up is one of the exhibits at the Chabot Space Science Center - it is a 1:1 copy, although many parents on the fiel trip though it was 'kid sized'.

(Yes I know I said 'first astronauts' but to be fair, Gagarin and Titov were called 'Cosmonauts')

Another installment of 'Things Kerbal Space Program Doesn't Teach' - explaining the expander cycle rocket engines in more detail. Expander cycles use the waste heat from the combustion chamber and nozzles to boil liquid hydrogen and power the turbines. The main advantages are cooler, less chemically active turbine environments, but if used in a closed cycle design the total thrust is limited.
Most of this material is at a pretty high level, I'm not a rocket scientist, I only play one on the internet.
Most of the flow schematics are taken from this excellent article by William Green

Lagrange Points are special locations in planetary systems where gravitational and rotational forces cancel out. Sometimes we find asteroids or dust clouds lingering near these places. Space missions may use some of these locations for spacecraft as they offer many advantages over orbiting in the Earth directly.
Universe Sandbox is used for some of the 3 body problem animations

Other graphics are created with GMAT and POV Ray
