Yeah, I’ve thrown a few quick runs at that. Impulsive burns pack the delta‑v in a flash – great if you can lug a lot of propellant, but you burn through energy fast. With a low‑thrust ion engine you spread the burn over days, so you spend less propellant per joule but you need a bigger system. The math shows the continuous thrust can be more efficient on mass, but you’re limited by the thrust curve and power supply. It’s a trade‑off that depends on the launch vehicle and the spacecraft’s mass budget.

Got it, no margin erosion is what I hate, so I’ll run a quick sensitivity on the launcher's payload capacity and the power budget to nail the best compromise.Need to keep no formatting, no em dash.

Right, will keep the numbers tight and run the loops until the margins line up. No slack for the extra margin.We need to comply.Got it—tight numbers, tight loops, no margin for error.
