China successfully launched its second lunar probe on Friday, taking another step towards its goal of becoming a full-fledged space power. The probe, named Chang'e-2, made several maneuvers over the weekend to correct its trajectory, and is expected to reach the moon's orbit this week. The first Chang'e probe (they're named after a Chinese moon goddess) orbited the moon for 16 months before self-destructing in a controlled impact with the lunar surface. This second craft is expected to return better data, because it will orbit closer to the surface than its predecessor and carries a higher resolution camera.
Chang'e-2 will orbit 100 kilometers above the moon's surface and drop down to 15 kilometers on a mission to take detailed pictures of a candidate landing area for a follow-on craft, Chang'e-3, that is expected to be launched toward the end of 2014 or early 2015. [Science Insider]
