NASA and the University of Arizona released more than one thousand pictures of Mars' surface taken by the HiRISE imaging telescope aboard the Mars Reconnaissance Orbiter.
The craft is able to send a large amount of data every 26 months, during what is known as "Mars opposition." At this time, Earth is between Mars and the sun, and the Red Planet is a lot closer to Earth. So we will have to wait another two years before another trove of images comes out.
