    “What’s the Delta-V Vector, Victor?”
    .
    @WaitingMan: Not only were you indeed being nit-picky, but you were wrong to boot. Google it.

    “You’re not ignoring the science stuff hard enough.” The true answer is “establish a hyperbolic vector that preserves angular velocity at Vesta approach, while maximizing camera hold time at dx=0.” Tweak those partial differentials until they squeal.

    Hmm. 2.572 A.U.s…
    Rediscover JPL’s old technologies and run a argon gas-core engine for 4.57 days at a half g and smack that baby right into the asteroid… POW!
    2.572 AUs=239196000 miles=1262954880000 ft

    Vo=37,500 ft/s
    1262954880000= 37,500t + 0.5(16)t2

    157869360000= 4687.5t +t2

    t=4.57 days

    Ssssssssmmmmaaaccckkk!

    Wonder what the impulse would be at that velocity…? (Of course, if the probe hit a sand grain at that speed, it would be in a lot of pieces…)

    Do not try and orbit the asteroid. That’s impossible. Instead… only try to realize the truth.

    -

    There is no asteroid.

    -

    Then you’ll see, that it is not the asteroid that orbits, it is only yourself.

    Eat a cookie. Nothing else matters.

    The answer is pi…preferably blueberry

    Ask NASAVoyager2.

    “What’s the best way to design a flight plan…?”
    Carefully!!

    Just don’t forget it’s metric again.

    Chaos.

    Winky wasted a perfectly good spleen on those bozos at NASA. They can’t even get a man off the ground! What’s the world coming to? (Never mind the asteroid.)

    So when do we get to buy Brewster T-shirts?

    The subtle effects of Vesta’s gravity field will cause deviations from the planned trajectory. NASA navigators should get repeated fixes on Dawn’s position and speed as it spirals closer. That should allow them to precisely point the thrusters, despite their being mounted on their own gimbals.

    Dr. Marc should know this . . . especially since he wrote it!
