The Mastcam is the same tool the rover has used to take stunning panoramaslike the incredibly high-resolution image of the Martian landscape it took late last year.

The goal of the image wasn't just to spot Earth but to get a look at the twilight brightness on Mars. It's spring in Mars' southern hemisphere where Curiosity is hanging about. "During this time of year on Mars, there's more dust in the air to reflect sunlight, making it particularly bright," said Mastcam co-investigator Mark Lemmon from the Space Science Institute.

Toward the bottom of the images, you can see the top of a rock formation called Tower Butte. Curiosity has been exploring this region for more than a year. This image should get people excited about NASA's next rover mission to Mars, Perseverance, which will land on the red planet in February 2021. It's currently scheduled to launch on July 20, 2020.
