Last night, Nasa's InSight finally fired off the Mars – after a long and incredible journey of 301 million miles.
And despite being on the red planet for less than 24 hours, he has already sent two stunning images back.
During her time on Mars, InSight will go back to Earth, giving us a detailed look at the alien landscapes of the remote planet.
And it will take measurements of Martian wind, seismic movements, and even underground temperatures – using a "mole" quiz.
But NASA has already spent enough time on Mars, and has a huge collection of Martian photography available online.
We have chosen some of the best images taken by the nearest neighbor of the Earth.
