Shuttle Challenge v5 - The STS thread [Stock and Mod Friendly] - MAJOR CHALLENGE ANNOUNCEMENT! - 30.3.2020 in Challenges & Mission ideas Posted March 19, 2018 7 hours ago, michal.don said: I'm glad you understand my reasons. The numbers I see in your screenshot are pretty wild again, so I'd like to know the stats of all the engines you'd like to use - I have to keep an eye on you for now Thanks! Well, the pressure's on now I guess. Anyway, that was taken with a pair of LF-9 "Colossus" magnetoplasmadynamic engines from nertea's near future stuff, packed with enough lithium to make a few million batteries. Unfortunately, that number was taken with lithium tanks everywhere, including the entire cargo bay. More of a "how much can I get out of this", since the Artemis is grounded for the time being, and was only serving as a testbed in the aforementioned image (and the fact that I don't have KER yet). Unfortunately, the new shuttle isn't quite ready yet. It's still being built from the ground up, with 0% of it being comprised of OPT engines. It is planned to have at least four "Repulsor" (i think that's what they're called) pulsed inductive thrusters (again from near future tech), which, provided you have sufficient power generation and heat management capabilities (to balance both additional heat output from the engines and the reactor to power it), can give you up to 9380 ISP. I can't say much else about the design of the new shuttle, or what engines it'll use since it's still not completed, and probably won't be for a week or so, IRL stuff has been and still is happening. As the design evolves I'll try to message you things about it to avoid cluttering up the thread more, if that's alright with you.
