It took us ages to get to this point, but we’ve finally scored some points. Scenarios 1001, 1002 and 1003 are working well now, though we’re still somewhat baffled by a mysterious problem with 1004. (Despite using what looks like a very reasonable thrust vector to widen our orbit, we instead descend and crash into the earth.)

Last night was fairly depressing; we were pretty close, but couldn’t quite get our algorithm correct in time for a lightning round submission. We were trying to use a standard Hohmann transfer orbit, but for whatever reason we were using our position to calculate when we should do the second burn, rather than the time, and were doing our second burn too late. It wasn’t hard to fix today, but we were just too tired last night to be able to make this minor change.
