Based on the surprisingly large variety of small-scale albedo features, I think that even early minerology results may prove VERY interesting. Fingers crossed...

A few will take this knowledge and use this power of a dream realized as a force for change, an impetus for further discovery to make less ancient dreams real.

Initial results are being announced today, some of which are already on the MESSENGER website.

Science update

Multimedia for the upcoming press conference (due to start in just five minutes) are now available too.

Multimedia link

Edit at ten minutes past the hour: News conference underway on NASA TV. Huge volcanic deposit at north pole.

Half past the hour: High level of potassium and sulfur, much higher amounts of volatiles than thought. Not so much iron and titanium as was thought from the flybys. Magnetic field way offset toward the north.

I had to answer my door and missed what Sean Solomon said about water ice at the poles. Did anybody hear?

Missing raw image access on this mission - I think we've been spoilt by the MER's and Cassini.

They used altimetry to produce a model of one of the craters, then modelled sunlight around the crater to see where the permanantly shaded areas are, and found that they do coincide with the radar-reflective areas - consistent with the ice interpretation.

Solomon also repeated his statements at the end, in reply to a question, and said that if the radar bright deposits are mostly water (the jury is still out), then Mercury likely has more water than the moon.

Oooh. Cool. Thanks for the summary.

There's a hilarious conversation going on on Twitter right now about the MESSENGER scientists' remarks about "Mercury is not dead like the Moon."

I love the pictures of the small volcanic vents. It's interesting to compare them with Ina (AKA D-Caldera) and the cluster of smaller features inside Hyginus on the Moon.

Anyone know if there is a link to a video replay of this? I searched but I'm not finding anything.

EDIT: I see it's being replayed at 4:00 my local time.

If Occam had heard my theory, things would be very different now.
