Wow! Look at that ground close to the lander. That looks just like a dried up mud puddle. I bet they find plenty of ice under ground. That white thingie is probably just a Martian Army sign warning about mine fields. |

| You'd think for around 1/2 billion dollars they could at least manage a level horizon. j/k :P |

And is anyone else unhappy with the overall composition?!? ;) |

I think that the sky should be a little more dramatic

Whoa, look at this image just in from the Mars Lander! It definitely shows WATER ON MARS!

I'm glad this one landed safely.
Someone asked an engineer about the 12 rocket engines that will soft land the craft on Mars. They said "do all of the engines have to function for a safe landing"...
...the engineer replied, "If one of the 12 engines fails, the other 11 will do an outstanding job of guiding the Phoenix Lander to the crash site".

This may well qualify as one of the coolist things I've ever seen. The Mars Reconnaissance Orbiter camera, HIRISE, actually spotted the Phoenix lander's parachute deployment. Woot!
Both these shots linked from Emily's Planetary Society Blog which I referenced earlier.

You can even see the shroud lines.
Whoa. |

| Perfect -- I just heard about this shot on the radio, and was going to look for the link. Pretty good for using a remost control with a fifteen minute delay ... |

| Holy cow, look at this! Be sure to click "enlarge" to see the bigger image. What a view. |

| Here is the landing site, showing Phoenix (near top), the parachute (near bottom) and the heat shield (right of center). The solar arrays on Phoenix are clearly visible. |

WAY COOL!! and either the heat shield or the parachute is likely to be the shiny thing in these pics:

call me a geeky nerd, but I LOVE this stuff!!! My only problem with the whole thing is that I want to go myself! |

Oh wow, it even looks like a dried up lake bed.
The darker area around the lander, is that from the jets? If so wont the area be contaminated now? I believe they used Hydrazine as the propellent? Isnt that massively toxic?

| That darkened area is surely from the lander rocket exhaust. Not sure what they used as propellant for this craft... I'm sure they considered the effects. Since they will be digging a ways down, the thermal effect of the exhaust on the surface shouldn't be a concern. |

Found this in their FAQ
Will Phoenix's descent thrusters alter the composition of its landing site?
Altering the chemistry of our landing site due to our thruster exhaust is unavoidable. The Phoenix Lander uses hydrazine, a hypergolic propellant that turns into ammonia during combustion. So essentially, we are spraying the surface with ammonia and a small amount of hydrazine that was not combusted. The way we get around that is by 1) knowing that we are going to be producing ammonia and 2) by designing the wet chemistry cells to carefully quantify the amount of ammonia in the regolith. We then use this information to interpret our other results.

Some sweet pics of the lander from above, plus the heatshield & parachute, are on this space.com article. Amazing the kinda detail the orbiters can pick up on the surface...

Saw those shots posted earlier - but interesting article saying a rough timeline of how long before they start using the arm, practicing scooping and delivering samples to the instruments. |

When I look at this shot, I see a riverbed. I call naming it! Compare it to the original, anybody else see it?
