Whoof, I haven't blogged in a whole month! I'm 10 blosts behind where I should be for the year!! Time to get my mojo back!!!

rldane.spaceA KSP Design Log

Time to play some #KerbalSpaceProgram.

Today's hare-brained idea: Make a space-faring learjet.

Not a spaceplane. A totally normal-looking learjet with jet engines ONLY that has mostly-recoverable appendages for boosting it up into orbit, and RCS/OMS (maybe a Terrier for the OMS, puff engines are mad inefficient).

But once it re-enters, it shouldn't be distinguishable from a totally ordinary learjet once the RCS/OMS pods have jettisoned and parachuted down to the KSC. ;)

One of the difficulty is that while the mk2 parts are more heat-resistant and spacious (like a learjet), they don't look like a learjet, so I don't think I can use them. I'll have to stick with very BBQ-prone mk1 parts. But I do have one trick up my sleeve that I'll allow some rule-bending for: a single non-functional rcs port at the very nose of the plane to shield the cockpit from excess heat during reentry.

Back into orbit and back to playing #Kerbal Space Program. Not sure why I've come back to the game after 5 years away. Felt the itch to finally go beyond Mun.

Running some mods, some quality of life (Kerbal Engineer, MechJeb), some cosmetic (chatterer, contract packs, some extra science (DMagic, Scansat).

A few questions for anyone that has played Kerbal Space Programme:

How long do you need to play it for to get to the core game? Do you need to unlock certain elements?

How long a play session minimum do you need to make it worthwhile?

How long would a first-time player take to understand how to play it? Is there a tutorial & can you easily replay it?

Would it suit 8-11 year olds?

I want to use it educationally.

NOTE: I’ve never played it and may purchase it.

Totally wrong things that Kerbal Space Program taught me*** about spaceflight:

  • Landing legs? Just land on the engine bells, they're nearly indestructible!
  • Reaction wheels are incredibly small and lightweight, are powerful enough to spin an entire rocket like a pinwheel, and never get saturated (can apply an infinite amount of torque in a single direction without needing to be reset).
  • There's only one type of liquid fuel, only one oxidizer, and only one type of monopropellant/RCS fuel
  • Rocket engines can be started up and shut down instantaneously, can be started an infinite number of times, and can be throttled down to a fraction of 1% of their maximum thrust smoothly, with perfect efficiency, and no combustion instability (or inadvertent self-destruct modes).
  • Liquid fuel tanks can be drained to 0% at any time without issue or need for ullage motors.
  • Fuel/Oxidizer never gets old or leaks
  • In extreme reentry profiles, multiple stacked heat shields can be used, and will fail gracefully and consecutively, with no risk to the craft.
  • Extremely small structural parts have no drag whatsoever
  • A tiny high-temperature-resistant part (such as a radial RCS port) at the tip of the nose of a part with low temperature resistance (such as a mk1 aircraft canopy) will successfully shield that part from most heating effects.
  • Docking rings/adapters have magic magnetism that works across impressive distances to draw craft together
  • Fuel pumps have an infinite amount of power, and can pump fuel from the bottom of the craft to the top of the craft while undergoing 10G acceleration.
  • Extremely tall crafts act like spaghetti, despite being made of fused metal parts, and require noodle-like metal strips called "struts" in order to remain structurally sound ;)
  • Nearly any part being destroyed gives off a combustive explosion, whether or not it contains combustible matter.
  • A gigantic space station only requires a single small solar cell of about 2 sqm to keep its batteries topped up

* not including things that are peculiar to Kerbal physiology, to Kerbin itself or the Kerbol system, such as the Kerbals lack of need for consumables, or Kerbin's size, or the Kerbol system's lack of n-body orbits
