Did anyone find a more complete HiRISE surface shot encompassing also the backshell? Did they crop it out due to lack of color coverage or what? I didn't quite understand if MRO succeeded in both imaging tries so this color shot is actually the second one? Full image here. More here. |

I liked the mars weather graphic they posted..
Is it posted somewhere or did they just create it for the press conference. be great to have that up on the web site cheers jb |

I missed the briefing, and I have a question about the parachute. I see an image http://www.nasa.gov/images/content/230826m...olor-browse.jpg of the lander and what looks to me like a crater where the heatshield bounced and a burnt heatshield, both to the southeast of the lander. I also see no sign of the parachute or backshell, and the link for the parachute image on http://hirise.lpl.arizona.edu/phoenix-hardware.php is broken. Did anyone see an image of the parachute?
Edit: I see it from a post above, thanks! So, do they have a better latitude/longitude for the lander reported yet? Also, when latitudes are reported, are they planetographic or planetocentric? |

That was my understanding from the press briefing. The first HiRISE image (11 hours after landing) was not precisely aimed at Phoenix, as its position had not yet been nailed down. It was captured in the wider B&W portion of the scan, but not in the central zone with colour. By the time of the second image (22 hours?), the location of Phoenix was precisely known, so MRO was able to capture it in colour, using the central zone of the HiRISE camera.

Fascinating that the backshell stained an area about half as big as the stain around Phoenix. That impact must have been pretty hard. I hope that minimizes the worries about the propulsion as a contaminant.

In fact, in the EDL+11 image, we at first only noticed the chute, the lander is barely visible (low sun angle, one of the solar arrays is in shadow). |

Question on the sliding rock:
Is it possible the helium venting right after landing moved the rock? It seems like the trail would have been blown away if that had happened. -------------------- |

Hi Guy,
Any chance the first image'll be released as well? -------------------- |

Truly a classic image, that hirise descent shot!
Has anyone else noticed that the impact points for both heatshield and backshell appear dark in the hirise shot? Presumably this means that there's no ice very close to the surface, otherwise I'd expect to see some bright debris or at least bright regions inside the impact craters. There shouldn't have been much time for exposed ice to evaporate? Anyone recall how deep Oppy's heatshield crater was? 20 cm or so? |
