NASA's Mars InSight lander, which touched down on the red planet on Monday, has successfully deployed its solar panels and transmitted its first image from the spacecraft's Instrument Deployment Camera, located on the lander's robotic arm.
Why it matters: For InSight to complete its mission of drilling deep into the interior of Mars, it needs energy to charge its batteries. The lander's mission could provide new insights into how Mars formed and evolved, which could shed light on Earth's history too.
