Mars "blueberries" give strong support to water theory

This false-color composite image, taken at a region of the rock outcrop dubbed "Shoemaker's Patio" near the Mars Exploration Rover Opportunity's landing site, shows finely layered sediments, which have been accentuated by erosion. The sphere-like grains or "blueberries" distributed throughout the outcrop can be seen lining up with individual layers. This observation indicates that the spherules are geologic features called concretions, which form in pre-existing wet sediments. (NASA)

LOS ANGELES, March 19 (Xinhuanet) -- The tiny, round "blueberries"found on Mars by Opportunity rover strongly support the theory that water once existed on the Red Planet, a NASA scientist has said.

Philip Christensen, a scientist from NASA's Jet Propulsion Laboratory in Pasadena, California, announced the finding at the 35th annual Lunar and Planetary Science Conference being held this week in Houston, Texas.

At Meridiani Planum where Opportunity has landed, a patch of tiny spherules -- also called "blueberries," was closely examined by a German-made Spectrometer at the rover's robot arm, and has now been identified as hematite, which is typically formed in water. The spectrometer is designed to study minerals that contain iron, which are common on the Martian surface.

Earlier this month, Opportunity has uncovered geologic evidence that the flat, featureless Meridiani Planum once was covered with water. Three days later, scientists announced that Opportunity's twin, Spirit, discovered signs that small amounts of water once welled up in the soil of Gusev Crater where the rover landed on Jan. 3.

What is the delay between when they send a RC comand and when the rover moves? like 3 hours? 3 days?

I don't think it would be days but I'm sure it would take several hours......remember long range subspace communications always too longer in teh early days of Star Trek.
