Didn’t plan this for the official challenge, just my Hail Mary from a month or 2 ago...
Think I used 6 of my then standard Titan Booster/Fuel Cans and a couple hours of idle ion burn, it’s slowed a bit but seems to have stabilized
Considering the program math shouldn’t light speed be 1/2, 1/3 or 1/pi or something of regular speed?
Working on a follow up coming around the sun again, not doing the math but should be several times faster
