BEIJING (AP) — China says its Mars probe and accompanying rover are expected to land on the red planet sometime between Saturday and Wednesday Beijing time. The China National Space Administration says the probe has collected a large amount of scientific data since entering Mars orbit on Feb. 10 and the window for setting down on an icy area of the planet was determined by “current flying conditions.” The rover is to stay in the lander for diagnostics tests for several days before rolling down a ramp to begin exploring for signs of life. The mission is the first attempt at a soft landing on Mars by a Chinese spacecraft.
