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
