thanks for the data, at least you back up your opinion. Thanks Phage....the only way to learn is to ask or research. My research sucked on this one due to time, but still had the question.

Is not outspace weightless? what would be the reason to go slower? To save fuel?? 3 months of extra flying saves fuel? again creates more questions than answers.

. Objects are weightless in space but still have mass and therefore have inertia. It takes energy to overcome inertia ie accelerate or decelerate an object. The Apollo missions took the direct route to the moon ,for the re to get ther
asons slayer ilustrated. In doings so they expended 5,929,000 lbs of fuel to get the 100,000 lbs of command,service modules and lunar orbiter to the moon in 4 days. That's six million lbs of fuel. Whereas for grail around147,000 lbs of fuel is used to get into orbit then each 400lb spacecraft,there were to onboard, then each craft has 150 lbs of fuel to take the gravity assisted slow ride there. That's a pretty big difference
