Subj : Daily APOD Report To : All From : Ben Ritchey Date : Mon Dec 10 2018 08:42:19 Astronomy Picture of the Day Astronomy Picture of the Day Discover the cosmos! [1] Each day a different image or photograph of our fascinating universe is featured, along with a brief explanation written by a professional astronomer. 2018 December 10 [2] Sound and Light Captured by Mars InSight Image Credit: NASA [3] / JPL-Caltech [4] Explanation: Your arm on Mars has unusual powers. For one thing it [5] is nearly 2 meters long, has a scoop and grapple built into its [6] hand, and has a camera built into its [7] forearm. For another, it will soon deploy your ear -- a sensitive seismometer [8] that will listen for distant rumblings -- onto the surface of Mars. Your SEIS [9] momet-ear is the orange box in the foreground, while the gray dome behind it will be its protective cover. Your arm is attached to the InSight robotic lander [10] that touched down on Mars [11] two weeks ago. Somewhat unexpectedly, your ear has already heard something [12] -- slight vibrations caused by the Martian wind [13] flowing over the solar panels. Light from the Sun [14] is being collected by the solar panels [15] , part of one being visible on the far right. Actually, at the present time, you have two arms [16] operating on Mars, but they are separated by about 600 kilometers. That's because your other active arm [17] is connected to the Curiosity rover [18] exploring a distant crater. Taken a week ago, rusty soil [19] and rocks are visible in the featured image [20] beyond Insight, as well as the orange sky of Mars [21] .
