Apollo 11 Part 3 of 3 "Coming Home". Videos were created in the free animation software tool called Blender. All models and animations were created by me. Textures of the Earth and Moon are from NASA.

Major scenes include:
1. Lunar launch of LM into orbit.
2. Rendezvous of Lunar Module (LM) with Command Module (CM)
3. Clean and Dry check of Command Service Module (CSM). This is where the CSM rotates around so the LM can inspect the vehicle. Note...I am not sure that Apollo 11 actually did this....but many if not all the subsequent Apollo missions did.
4. Docking behind the Moon
5. Jettison the LM. Note that the LM is now in an interesting configuration. The docking drogue has been removed since they don't need it anymore. Because of this, you have a clear shot of the top of the upper Hatch. Also as part of the jettison cycle the CM docking ring/latches remains attached to the LM. The latches are blue.
6. Trans Earth Injection (TEI) burn back home
7. Separation of CM from Service Module (SM). I actually took the time to animate the reaction control system (RCS) for this event. In most videos that I watched, you can rarely see the RCS exhaust plumes. The SM RCS fires to put distance between the CM and SM and also induces a roll. The CM fires its pitch RCS to get into the proper reentry position. During separation, a pyrotechnic guillotine severs the connection between the CM and SM and the Umbilical Assembly rotates back. This is followed by another explosive guillotine that separates the SM from the CM.
8. Reentry. The friction heat up the hull. The hull has a shiny coat which wears off during reentry. I gave it my best shot trying to animate what this may look like going from very shiny to dull and charred. The CM does several roll maneuvers to control its lift vector which can make the entry more steep or less shallow or induce some cross range.
9. Parachutes. There are 9 parachutes total. I animated them all but some you only see for a very short time. The apex cover (top of the spacecraft that shields the parachutes and mortars) is jettisoned at 24,000 ft. The apex cover has its own parachute. The 2 drogue chutes deploy 2 seconds later to slow and stabilize the CM for about 10 seconds before they are cut loose. This is followed by 3 mortars firing 3 small pilot chutes whose purpose is to drag out the very large orange and white main parachutes. No...I did not take time to animate the altimeter that is clearly in view by the forward left window. The altimeter has marks on it to note when each parachute event is triggered.
10. Splashdown. CM lands and immediate turned over upside-down (Stable 2). Not all CMs flipped over....but Apollo 11 did. This is followed by an air compressor inflating 3 floatation bags used to flip the CM to Stable 1. Turns out that the Apollo built in compressor was an off the shelf compressor. So when adding sound, I used standard compressor and hissing noises.
