I believe there have been something like 14 separate studies showing that vaccines have zero link to autism. Not vaccinating your kids nowadays is incompetent parenting, and puts everyone at risk.
In addition to what the others have said, in most cases, those unidentified objects turn out to be ice, gases from the thruster fluorescing, or debris from staging or EVAs. Without a point of reference in space, it becomes rather hard to judge distance and size of an object.
If you have the technology to handle the incredibly, stupidly huge energies needed to travel between the stars, all the missiles on Earth don't mean a thing to you.
Before the landing, they were talking about being worried about landing on a "hill" near the center of the possible landing area. The hill was only a couple meters tall, so this could be it.
I'll point out to you that you linked to a popular source written about one single peer reviewed source, while the GP linked to a peer reviewed report about many other peer reviewed papers that contradict your study.
In addition, Marvin says the same thing during Restaurant and the end of the universe when they are trapped in the stunt ship. He reads the question right out of Arthur's brain.
It wouldn't be reentry shielding, but consider this. While in orbit, the satellite would experience two temperature extremes, one in sunlight, and one in shade. In shade, the temperature would be a few degrees above 0K. In the sun, you have a large heat flux (1347 W/m^2, is the average, I believe,) and no way of getting rid of that heat except radiation or reflection. So these tanks, in addition to being able to withstand large pressure differences between the interior and exterior, were also very well insulated, and effective at dispersing heat. So you've got a tough tank and system in general that can handle temperature extremes as well. I can understand why there was a concern about the hydrazine.
Actually, pointing something towards the sun wouldn't really send your payload into the sun unless you pushed really, really, really hard. To get something to approach the sun using chemical rockets, one must think about the concept of an orbit. An orbit is defined by the object's speed around its central body. Thus, in order to get closer to the sun, your payload would have to drop its orbital velocity to near enough to zero, if you want a fast collision. You would need to use energy to get to the limit of earth's gravitational influence, about 1,000,000km out. At this point, you would essentially moving with the same orbital velocity as the earth with respect to the sun. Escape velocity for Earth is about 11km/s. With respect to the Sun, the Earth has an orbital velocity of about 48km/s. This means that to get you probe to go on a straight line to the sun, you would need 59km/s of delta v, which is a hell of a lot, and delta v is (essentially) directly proportional to amount of fuel you must carry. Now, granted, you could take a more circuitous route to arrive at the sun, and use less delta v, but it would still be a significant fraction of the 59km/s.
With regards to you second question, unless the highly inclined orbit was altered again at perigee and apogee with respect to the sun, your payload would return to the Earth's orbit.
Note: I am not a rocket scientist, at least not for a while, but I have done a bit of interplanetary stuff like this. All the numbers come from google. And it is entirely possible I'm quite mistaken, but I hope this was a bit helpful.

Pity that in many many places, there is no competitor.
As a failsafe though, it is wise to remember that any encryption can be broken, and any ID can be spoofed.
Godwinned!

Which is exactly why Chicago is going to get the 2016 games. We've got the patent on the time honored political methods.
Put it this way... Ledger's joker scared the shit out of me whenever he was onscreen.
But there is theory.
Of course, there's always what a wise man once said... "There are lies, there are damn lies, and then there are statistics."
"A Wrinkle in Time"? It's quite a good book, and aimed at generally the same age group as your kids.
I see you have been Touched.
Dude, you know no one leaves a carton of Ben and Jerry's half empty! It's gotta be the casserole.
So in other words, in the beginning, God wrote his code and hit Enter.

And I've apparently been here longer than I thought.... Dear god, help!
Of course we can't. You must be new here.

Oh, where are my mod points when I need them?
Once every 90-odd minutes, actually.
Dear sir, I agree.
