Thanks for the link, VanderL.

However, I looked at the figure with the four measurements here, Water Vapor Measurements.

Perhaps others can see useful information there, but frankly I was very disappointed.

I expected quantitative information on the major comet constituents from NASA's much celebrated Deep Impact on the 4th of July .

Are there other links which give relative amounts of

a.) Rocky material
b.) Water, and
c.) Hydrocarbons

in the comet?

I would hate to see the Deep Impact event go the way of the Genesis Mission and fade from view with nothing but empty promises.

With kind regards,

Oliver

Hi Oliver,

There is some information on what has been found thusfar this website contains all publicly available images/spectra. I share your concern about the sparsity of available data. Of course the Deep Impact team will make sure Nature and Science publications will come from the data. This is only natural, but it is a frustrating wait for additional information.

I'm curious why you think the water data are disappointing, the curves show all that is needed, the peak's area under the curve is the amount of water vapour, pre-impact and post-impact. The difference is the increase in water vapour by the impact, and it is almost non-existent. So, one conclusion can be made: comets are not "dirty snowballs".

Another finding is that no complex organic molecules were detected (as were found in comet Hyutake).

Cheers.
