Mercury Messenger: An article in the June 17 Section A about NASA’s Messenger spacecraft mission to Mercury attributed a quote about the possibility the planet might have more polar ice than Earth’s moon to Jim Green, director of NASA’s Planetary Science Division. The remark was actually made by Sean Solomon, the mission’s lead scientist. Likewise, it was Solomon, not Green, who said Mercury was once considered “the burnt-out cinder of the solar system.”
