We’ve learned a lot about Mars in recent years. Multiple orbiters and hugely-successful rover missions have delivered a cascade of discoveries about our neighboring planet. But to take the next step in unlocking Mars’ secrets, we need to get Martian samples back to Earth.
NASA's InSight lander isn't camera-shy. The spacecraft used a camera on its robotic arm to take its first selfie — a mosaic made up of 11 images. This is the same imaging process used by NASA's Curiosity rover mission, in which many overlapping pictures are taken and later stitched together. Visible in the selfie are the lander's solar panel and its entire deck, including its science instruments.
