This is an artist's concept of the Mars Reconnaissance Orbiter during its critical Mars Orbit Insertion process. In order to be captured into orbit around Mars, the spacecraft must conduct a 25-minute rocket burn when it is just shy of reaching the planet. As pictured, it will pass under the red planet's southern hemisphere as it begins the insertion. Image(Image credit: NASA.)
