Note the wording of the press briefing has no certainty whatsoever that any XXM might be approved. This burn simply preserves the option.
AFAIK - an XXM is yet to be approved.. |

from the Facebook page of the Deep Impact Flyby, it looks like 5,246 images were taken last week, but I have no idea of what the target was...
any info? |

Just curious, did you try asking that question directly via Facebook?

I don't know if my reply are any meaningful either, but was not the craft supposed to participate in the search for extrasolar planets?
The images taken could be part of EPOXI = Extrasolar Planet Observation and deep impact eXtended Investigation |

Multiple new datasets from Deep Impact are available now. The most interesting is probably this one - dif-c-hriv-5-epoxi-hartley2-deconv-v1.0, which contains deconvoluted images of Hartley comet from HRI camera.

Very nice! The document folder contains JPG previews of the images for people who don't need the full data.

I don't know if this relates to Paolo's question above, but Deep Impact is now in an imaging/IR spectroscopy study of Comet ISON.

I wonder how much fuel the study of comet ISON will use. The 2020 NEO encounter is very tight on fuel as it is.

Simply turning the spacecraft around can be accomplished by reaction wheels with no propellant expediture. Only wheel momentum unloading requires actual propellant to be used, but that has to be done periodically either way.

QUOTE (monty python @ Jan 21 2013, 01:42 AM)  The 2020 NEO encounter is very tight on fuel as it is. Read the PDF linked to a few posts above - you will see that fuel isn't the problem for the 2020 encounter. Funding is. There's enough fuel to get it done. There's no funding for it. And - as ugordan says - just pointing the spacecraft requires, essentially, no fuel at all. |
