                         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.

                     InSight Lander Takes Selfie on Mars
                   Image Credit: NASA [3] / JPL-Caltech [4]

Explanation: This is what NASA's Insight lander looks like on Mars. With its
solar panels [5] , InSight is about the size [6]  of a small bus. Insight
successfully landed on Mars [7]  in November with a main objective to detect
seismic activity [8] . The featured selfie is a compilation of several images
taken of different parts of the InSight [9]  lander, by the lander's arm [10]
, at different times. SEIS [11] , the orange-domed seismometer [12] seen near
the image center last month, has now been placed on the Martian surface [13] .
With this selfie, Mars InSight [14]  continues a long tradition of robotic
spacecraft on Mars taking and returning images of themselves, including Viking
[15] , Sojourner [16] , Pathfinder [17] , Spirit [18] , Opportunity [19] ,
Phoenix [20] , and Curiosity [21] . Data taken by Mars Insight is expected to
give humanity unprecedented data involving the interior of Mars [22] , a
region thought to harbor formation clues [23]  not only about Mars, but Earth
[24] .
