As we have a few subcategorys, but not one dedicated topic about space.
That and there spread out around Arse, so thought might as well try have a home of it.

I do not in any way shape or form go for men but if i did it would be Chris Hadfield .
Plays guitar, sings and on occasions goes into space , in these days of American /Australian Idol that guy is the only one that truthfully can claim the title. And the other awesome Nasa and Russians etc etc

richo, He is Canadian.
That was just one of the Photos of it I have seen a few can't remember where the others where hosted now though.

Commander Hatfield reminds me of Walter from Breaking Bad.

I know he is Canadian , ,my point although badly worded and executed is that guys like Hadfield are worth emulating rather than Australia/American Idol whatevers .

You can start anywhere.. then just move and zoom out and you can see the world change.
Yonatan Zunger wrote:Jupiter and the Sun are the two largest objects in our Solar System, and as they orbit around one another, they create regions where their gravity roughly cancels out. These are the Lagrangian points, created whenever two objects orbit one another: places where gravity is such that another small object can follow along in the orbit without being pulled in or out. And since things aren't getting pulled out of there, they get stuck in there as well: and so we have two large clumps of asteroids (and miscellaneous smaller space debris) in Jupiter's orbit. These are called the Trojan Asteroids; the group ahead of Jupiter is known as the Greek Camp, and the group behind it the Trojan Camp, with the asteroids in each camp being named after famous people in that war. Together, these two camps have as many asteroids as the Asteroid Belt.
Other stable patterns are possible, too: another one is what's called a 3:2 resonance pattern, asteroids whose motion gets confined to a basically triangular shape by the combined pull of Jupiter and the Sun. This group (for Jupiter) is called the Hilda Family, and their route forms a triangle with its three points at the two Lagrange points and at the point on Jupiter's orbit directly opposite it from the Sun.
None of these orbits are perfectly stable, because each of these asteroids is subject to pulling from everything in the Solar System; as a result, an asteroid can shift from the Lagrange points to the Hilda family, and from the Hilda family to the Asteroid Belt (not shown), especially if it runs into something and changes its course.
The reason that Pluto was demoted from planet to dwarf planet is that we realized that these things are not only numerous, but some of them are quite big. Some things we formerly called asteroids are actually bigger than Pluto, so the naming started to seem a little silly. So our Solar System has, in decreasing order of size, four gas giant planets (Jupiter, Saturn, Neptune and Uranus); four rocky planets (Earth, Venus, Mars, and Mercury); five officially recognized dwarf planets (Eris, Pluto, Haumea, Makemake, and Ceres); and a tremendous number of asteroids. (We suspect that there are actually about 100 dwarf planets, but the job of classifying what's an asteroid and what's actually a planet is still in progress -- see the "dwarf planet" link below if you want to know the details)
Ceres orbits in the Asteroid Belt, about halfway between Mars and Jupiter, just inside the triangle of the Hilda Family; Pluto and Haumea are both in the distant Kuiper Belt, outside the orbit of Neptune but shepherded by its orbit in much the same way that the Hildas are shepherded by Jupiter; Makemake is what's called a "cubewano," living in the Kuiper Belt but unshepherded, orbiting independently; and Eris is part of the Scattered Disc, the even more distant objects whose orbits don't sit nicely in the plane of the Solar System at all, having been kicked out of that plane by (we believe) scattering off large bodies like Jupiter.
But mostly, I wanted to share this to show you how things orbit. This picture comes from the amazing archive at http://sajri.astronomy.cz/asteroidgroups/groups.htm" onclick="window.open(this.href);return false;, which has many other such pictures, and comes to me via +Max Rubenacker.
Pluto's newest and teeniest moons are now named Kerberos and Styx. I kinda liked the idea of Vulcan, but the new names really are more logical. http://www.slate.com/blogs/bad_astronom ... cters.html" onclick="window.open(this.href);return false;

That Proton launch was ugly. Still, it happens. Proton is not and has never been man-rated, just in case anyone was wondering...
I'm always fascinated by the YT comments like "Russian quality LOL!" and the like. Apparently nobody there knows about the nearly-1800 successful Soyuz launches. Protons have had their problems - as indeed have Soyuz - but few of the ones that work get seen.
All of the recent manned ISS missions* have been from Soyuz TMA rockets.
* Including Chris Hadfield

Good launches are less spectacular and get less press.
