On Mars, at 15:00 local true solar time on May 2, a solitary rover gazed southward across her own dusty deck and snapped three photos, actually three sets of three photos, which were combined to make this view. As the Mars Exploration Rover Opportunity shot these images of Meridiani planum, the same Sun that dictates the rhythms of our human lives was sinking toward the rover's western horizon, casting a lengthening shadow toward the east from the upright gnomon on the little sundial on the rover's rear deck. That sundial is engraved with the words "Two Worlds, One Sun" to mark the unity of Earth and Mars as part of the same solar system.While sorting, the Times chose a few to spotlight some of their initial submissions in separate blog entries:
For gear-savvy readers who’d like to try this themselves the next time they’re on Mars, NASA explained how it was done:Love it. :DThis scene is a three-tall by one-wide mosaic of Pancam images taken through the camera’s red (602 nanometer), green (530 nanometer) and blue (480 nanometer) filters. It has been calibrated and processed to approximate the colors that would be seen by humans if they could be present for this lovely Martian view. The camera took the images during the 2,229th Martian day, or sol, of Opportunity’s mission on Mars.Dr. Bell gets the photo credit. His caption reads: “Two Worlds, One Sun: While humans’ lives unfolded on Earth, the Mars Exploration Rover Opportunity paused in its southward trek and captured this photomosaic taken around 15:00 local Mars time on May 2. Dusty, reddish-brown sand dunes stretch southward along the route to the horizon.”
Because the mosaic composite was assembled at Cornell — and, more importantly, because we had no geocoding available for the Meridiani Planum — we slipped our version of the picture into a stack rising over Ithaca, N.Y.
Wait a minute! Local time?
