There once was a Neptune orbiter mission in the works:

And even older mission:
https://en.wikipedia.org/wiki/Mariner_Mark_II

Of course both were cancelled. No money.

Finals commiseration thread?

Idiotic question.

no shit sherlock

You fucking idiot, the moon's gravitational pull on Earth is negligible. Also you're being an enormous autistic asshole for taking typos in the pic at face value.

>The diagram doesn't make sense. If the center of the moon were 100m from the Earth's surface, then they would already be touching.
AT LAST A CORRECT STATEMENT

>If you mean the measurement is from the surfaces of the apple and moon, then the apple would touch first because the acceleration on the center of the moon is less than on the center of the apple being farther away.
Dumbass, acceleration is always g in Earth's vicinity.

>This would have to ignore tidal effects and assume that loose pieces of the moon wouldn't just fall off towards the Earth. But assuming that the moon and apple keep their shape, the apple touches first.
Since the whole process would take a few seconds at most, taking ridiculously negligible effects is useless at best. What's next, taking tunnel effect into account?

>>4897491
He's not. Dumbass.

>>4897494
But then that's retarded. An apple doesn't take hours to fall. Do you even think?

>>4897497
Babby's first newtonian mechanics, Earth weighs much more than the moon so any reciprocal gravitational pull can be neglected.

RESEARCH FUNDING, HOW DOES IT WORK

Let me say this instead of the tripfag. You are a complete and absolute moron that makes me want to start an eugenics program tailor made just for your stupid ass.

>>3947357
Fuck, I raged. People like you are a blight.
>hurrdurr kidz r stoopid
No, they don't. Statistically, they are smarter that you. And their kids would be smarter again.
Face it, your generation is not a fucking peak in human development.

>Skeptics believe that water has no role in human health other than basic hydration. Water is inert, they say, and the water your toilet is identical to water from a natural spring (assuming the chemical composition is the same, anyway).

Ok does anyone have any idea why this shit doesn't work on windows 7? Try reinstalling, changing the compatibility settings and everything but it shuts down as soon as I come to the section where you choose which of the following atlases (human brain, developing mouse brain) you want to install.

all this thread is gonna be is a buncha capitalist bashing.... go fuck Michal Moore OP.

Governement is not the foundation of all things.

scholarship hunting is pretty much a joke. my parents are high-income, so that dq's me for 98% of scholarships and work-study. I'm not bi-racial, minority, gay, native-american, don't have aids/cancer, am not an amputee, not a veteran, etc, so that dqs me from a remaining 1.5%.
for the others, I'm not willing to spend 40 hours working on a scholarship for $250. (or a 1/5 chance at $2500) its just not worth it.
Most the money comes from my parents (and do they whine about it), and I contribute what I make from my minimum-wage jobs. I'd do student loans if I didn't have this.
If I worked full time i'd only make $14k a year, that's not even enough for a full year of school :/

UTILITY FOG?


holy fuck...not this shit again...

well sure.

it's just your asking how to build a space shuttle from the ground up and acting like it'll only take the weekend to learn it all

...bad analogy I know, but damn close enough.

dumbass
