The unmanned US$165 million Phobos-Grunt, launched on 9 November 2011, was intended to fly towards Mars and return with a sample from the surface of Phobos, one Mars' moons. The spacecraft was launched successfully, but a rocket malfunction failed to set the probe on a course to Mars, leaving the spacecraft stranded in a low Earth orbit.
According to information from mission control of the space forces, the fragments of Phobos-Grunt should have fallen into the Pacific Ocean at 1745 GMT (approximately 4:45am Sydney time), said Phobos-Grunt spokesman Alexei Zolotukhin.
