THE NEW SPACE RACE: Chang’e-6 heads for Earth with first-ever lunar far side samples. “The Chang’e-6 service module likely fired its engines for a trans-Earth injection around June 21. The spacecraft is now on the final leg of its complex, 53-day voyage involving a lunar landing, sampling, ascent and docking. A reentry capsule containing the unique samples will be released from the service module shortly before arrival at Earth early June 25.”
