theres so many fucking resources in space. Why would a race with the technology to access them bother with people on some planet? Life itself is the only resource unique to earth- thus coming here to exterminate it makes little sense.
Slaves, sport, fun, because they can?

People like to think that some space faring race has their shit all together and got their differences settled. That they are somehow above barbaric acts or better in some way. If their history or evolution was anything like ours its more likely success came at the end of a pointy stick or blaster as they trampled and exploited the weak.

Sure they could be peaceful intellectuals like the Vulcans or they could be out looking for a new fashion and the Human Skin suit or body replacement just bought them another 6 billion coats.

Apparently the issue with the new horizons probe was a timing issue in its command sequence. They say there's no hardware or software damage, and things should continue as planned soon (july 7th).New Horizons

Good news, because pictures taken soon should be roughly twice the resoultion of the ones we last saw. We're very close to the point where shit will get exponentially better in a very short time frame.

This probe is a neat exercise in conceptualizing light speed. Its a 9 hour round trip to communicate with the probe using a signal traveling at light speed. That's an astonishing distance. We are like 8.3 minutes from the sun. We are communicating with something 67.5 times further away from us than the sun is from earth with my napkin math skills.

That Pluto/Charon orbiting gif makes it appear as though Pluto is tidally locked.

And to put it further into perspective, Voyager 1 takes about 36 hours for one-way communication!

*edit* My bad, that is for 2-way. Just over 18 hours for one-way.

Another fun fact I am trying to figure out.. Voyager 1 was launched in 1977 and travels at ~38,000 MPH. New Horizons launched in 2006 and only travels 9,000 MPH. How has it already covered 1/4 of Voyager's distance (based on communications time napkin maths) in relatively short time?

Voyager 1 = currently 131.89 AU from the Sun
New Horizons = currently 32.84 AU from the Sun

Different looping path around orbital bodies? Maybe one's path was more able to go away from the sun?

You beat me with the mcconaughey shoops!

New Horizons launched with the fastest escape velocity, but only had 1 gravity assist by Jupiter. Voyager got a few gravity assists, hence its far greater speed.

Another fun read:

Error my ass. How did you think a Cthulu egg orbiting the solar system waiting for the sign of an emerging spacefaring civilization to feed on would defend itself?

While we're waiting on Pluto stuff to resume tomorrow, here's some Mars.
