What a journey.
NASA's current project to put people above low orbit... love this frame grab from one of their videos. When they capture the returned capsule, they drape it to protect it....
Billion dollar project. Saving funds by using perfectly good used tires to protect the capsule.

That's the level of engineering that I'd likely have been assigned to.. "Hey BILL... can you throw together something to protect the paint? Oh, and you have $15.76 budget... last minute thought... sorry"....

Love the trimaran in the background. I believe that one was built in Australia.

My eyes did not even detect it was a tri.

New Horizons is awake and about as far from Pluto as the Earth is from Mars (if I did my math right). That sucker's going fast.


It was interesting to check out distances from the sun

Mercury 0.387 A.U.
Venus 0.723 A.U.
Earth 1.000 A.U.
Mars 1.524 A.U.
Ceres 2.8 A.U.
Jupiter 5.203 A.U.
Saturn 9.523 A.U.
Uranus 19.208 A.U.
Neptune 30.087 A.U.
New Horizons 33 A.U.
Pluto (variable, at present 33.652) 39.746 A.U.
Eris 96 A.U.

Those ion engines, man. Slow off the line, but constant acceleration is like compound interest.

After Reading this post the other night I looked up some of those planets and other bits and bobs on the Solar Walk app.

There's some awesome little snippets of information in the app. Highly recommended.

Interesting. Can you tell me what you like best?

God, that last post read terribly. I was trying out the dictation feature in iOS8 and I sound like a freakin' robot.

I was intrigued with the different gravitational forces at surface level on different planets. For eg Earth and Saturn are pretty similar because even though Saturn is way more massive, as a gas giant it's far less dense. Jupiter's gravity is slightly more than double earth's even though it's ridiculously bigger. Uranus, while over 14 times more massive, has lower surface level gravitational force (8.43 ms2 vs 9.8 ms2)

As well as the usual stuff, there's stuff about numerous satellites in low earth orbits, numerous dwarf planets, comets & nearby stars.

(Cosmographica is better for the Mac though...)
