You guys hardly left any for me to translate :). In the "Origin of the planet's high luminosity and the presence of ice" section, the article stated that 2.4 GHz SHF waves were used to make a radar map of Mercury's surface. AFAIK (and our own EM spectrum article agrees) 2.4 GHz falls into the UHF band, so I changed that. Another great translation, guys! Fernando Rizo 30 June 2005 00:57 (UTC)

Bringing things up to date[edit]

Some of the news releases and progress reports I'm finding make some of the info in this article obsolete. I find it easier to be bold when I feel there is some sort of concensus so I'm seeking input.

Sometimes, its what the scientists don't say that speaks volumes. I have found no one going out on a limb in saying Mercury is geologically active, but MESSENGER team members have stated some of the flood volcanism covering a large percentage of Mercury's surface is "recent" and some is "ancient." Many cones, some upwards of 25 km have been distinguished, with a team member refering to one cone in particular as "fresh." Volcanic rocks dominate the entire surface, even in regions that are geologically complex (whatever that means) and in areas surounding impact craters.

It's magnetic field is shifted toward the north by 20% of Mercury's radius, the largest ratio of all the planets. It is believed by the MESSENGER team to be the result of one or more molten layers creating a dynamo effect similar to Earth, but until further study is done, they're not sure. Not being a geologist I have to ask: How could Mercury not be geologically active? Between its highly-elliptical orbit, uneven heating and close proximity to the sun's forces, I would think the stress would be to some degree like what Io endures.

Rather than use the sentence "Currently, the surface is presumed to be geologically inactive" (for which I can't find a citation), I'd opt for something more along the lines of "The level of geological surface activity is currently uncertain" and follow it up with recent findings and citations. I don't feel this crosses the line of WP:OR. Anyone agree or disagree? Ken Tholke (talk) 21:22, 17 February 2012 (UTC)[reply]

Ken: You were not only to date, but a couple of years ahead.

Now, 4 years later, some scientists are beginning say the same out loud. Flood volcanism within the last 100 My ^[1] or at least the last 1 Gy.^[2]

Sorry about format. I'm not a regular. 2602:306:CE2B:6E0:5CEC:17B8:7FC5:49BC (talk) 19:40, 26 March 2016 (UTC)[reply]
