The first Americans in space, Alan Shepard and Virgil Gus Grissom, led the beginning of Project Mercury on-board the Mercury-Redstone. Unlike any other manned missions these two launches were sub-orbital but answered many important questions about the nature of space flight and paved the path up all the way to the current day.

Thanks to FASA being given new life this is my build of Mercury-Redstone although it’s simpler than my previous FASA Mercury-Redstone build by focusing entirely on FASA parts.

The rocket itself is only meant for sub-orbital travel with a projected apogee between 80 and 100km and a mission time between 15 and 20 minutes. The rocket should begin its pitch program once it reaches a velocity of about 100 m/s and should end up at a pitch of about 60 degrees by the time the rocket has exhausted its fuel supply. The launch escape system should be ejected first a few seconds after the engine has finished its burn followed by decoupling the space capsule from its lifter.

Since the mission is very short you actually have a great excess of supplies including ablative shielding and monopropellent. The retro engine pack is unnecessary for re-entry but a semi-realistic approach would have you fire it about half-way to your apogee which will lower your apogee significantly. You should rotate the capsule around for a great view of KSC and loudly identify cloud cover and landmarks as you spot them.

The retro engine should be ejected just as you begin re-entry with re-entry being a bit bumpy which can be smoothed out with a gentle rotational spin to stabilize your re-entry. The capsule is equipped with a makeshift drogue chute and a main chute which won’t be deployed until you are almost into the lower atmosphere. The drogue chute should bring your velocity down considerably and should be cut just after you deploy your main chute resulting in a comfortable splashdown.

Built in the VAB in KSP version 1.4.3.
