After over six months of travelling through space and covering a journey of more than 300 million miles, NASA's InSight mission landed on the surface of red planet, Mars.

A few minutes after landing, InSight sent the official "beep" to NASA to signal that it was alive and well, including a photo of the Martian surface where it landed. And right on cue, the newest man-made rover on Martian soil has sent back its first two pics of the alien world.

InSight will take two to three months for the robotic arm to place the mission's instruments on the surface. InSight will unfold its robotic arm and study the entire planet from its parking spot. It's along the Martian equator, bright and warm enough to power the lander's solar array year-round.

It was NASA's ninth attempt to land at Mars since the 1976 Viking probes. All but one of the previous U.S. touchdowns were successful. NASA last landed on Mars in 2012 with the Curiosity rover.
