Cool image of Phobos.

Excellent. 🙂

I can't hear Phobos without thinking of Q3A

 

[Miramonti]

My google finger is broken, how big is that?

roughly 2600 x 2151 pixels.

about as cool as a picture of Phobos can be, i guess.

I was waiting for that one.

Because that's what I'd say. 😉

 

[ElFenix]

i don't see the gate to hell, must be on the other side

Where are the latex babes? Where is the Galaxy Galleria Mall?

 

[RearAdmiral]

Unbelievable. So far away.

 

[Evadman]

I don't see the cyberdemon. He must be on the other side.

About 9400km across.

I wonder what caused the long parallel gouges. Looks like there's a lighter set of gouges almost perpendicular to the heavier ones.

Tooling marks. It hasn't been lapped yet.

Many grooves and streaks also cover the oddly shaped surface. The grooves are typically less than 30 meters (98 ft) deep, 100 to 200 meters (330 to 660 ft) wide, and up to 20 kilometers (12 mi) in length, and were originally assumed to have been the result of the same impact that created Stickney. Analysis of results from the Mars Express spacecraft however, revealed that the grooves are not in fact radial to Stickney, but are centered on the leading apex of Phobos in its orbit (which is not far from Stickney). Researchers believe they have been excavated by material ejected into space by impacts on the surface of Mars. The grooves thus formed as crater chains, and all of them fade away as the trailing apex of Phobos is approached. They have been grouped into 12 or more families of varying age, presumably representing at least 12 Martian impact events.

Neat stuff.

Cool pic, OP. Reps.

I immediately thought of Q3A as well.

 

[McWatt]

About 9400km across.

That's the semi-major axis of its orbit. Phobos itself is tiny and irregular: 18 x 22 x 27km.

Someone else fixed it more accurately 🙂
