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.

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] .
