    China’s Moon Landing: ‘New Chapter in Humanity’s Exploration of the Moon’

    By Steven Lee Myers and Zoe Mou BEIJING — China reached a milestone in space exploration on Thursday, landing a vehicle on the far side of the moon for the first time in history, the country's space agency announced. The landing of the probe, called Chang'e-4 after the moon goddess in Chinese mythology, is one in a coming series of missions that underscore the country's ambitions to join — and even lead — the space race. China landed another rover on the moon in 2013, joining the United States and the Soviet Union as the only nations to have carried out a “soft landing” there, but the Chang'e-4 is the first to touch down on the side of the moon that perpetually faces away from the Earth. The mission “has opened a new chapter in humanity's exploration of the moon,” the China National Space Administration said in an announcement on its website. The agency said the spacecraft landed at 10:26 a.m. Beijing time at its target on the far side of the moon. The probe sent back to the earth the first close-up image of the moon's far side using a relay satellite China calls “Queqiao,” or “Magpie Bridge,” the space agency said in a notice that included images it said were taken by the probe. Although a latecomer by decades to space exploration, China is quickly catching up, experts say, and could challenge the United States for supremacy in artificial intelligence, quantum computing and other fields. “This space mission shows that China has reached the advanced world-class level in deep space exploration,” said Zhu Menghua, a professor at the Macau University of Science and Technology who has worked closely with the Chinese space agency. “We Chinese people have done something that the Americans have not dared try.” China now plans to begin fully operating its third space station by 2022, to put astronauts in a lunar base by later in that decade, and to send probes to Mars, including ones that could return samples of the Martian surface back to Earth. Though the moon is hardly untrodden ground after decades of exploration, a new landing is far more than just a propaganda coup, experts say.

    Next-gen Combat Aircraft Development Gains Momentum

    Graham Warwick | Aviation Week & Space Technology The UK launched its £2 billion ($2.5 billion) Future Combat Air System Technology Initiative in 2018. Team Tempest—the UK Defense Ministry, Royal Air Force, BAE Systems, MBDA, Rolls-Royce and Leonardo—is also in talks with Sweden and Saab about joining the program. The team was to present its strategic outline business case at the end of 2018. The FCAS main-gate procurement decision is set for 2025 and service entry targeted for 2035. http://aviationweek.com/defense/next-gen-combat-aircraft-development-gains-momentum

    Ready, Fire, Aim: PACAF Chief Emphasizes Hypersonics

    Steve Trimble As the U.S. Defense Department accelerates hypersonic weapons fielding, the air force's top commander in the Pacific region emphasizes that the missile isn't the only technology required to realize an operational capability to strike targets at speeds faster than Mach 5. The air force plans to achieve an early operational capability in fiscal 2022 with the Lockheed Martin AGM-183A Air-launched Rapid Response Weapon, a maneuvering boost glide missile fired from the wing of an aircraft, such as a Boeing B-52. Such weapons are capable of hitting targets at ranges over 1,000 km within 10 min., but similarly new advances in intelligence-gathering and command and control infrastructure are required in order to make full use of them, said Gen. Charles Brown, commander of Pacific Air Forces. “In the time of flight, eight to 10 minutes, I've got to have pretty good intel that the target is still going to be there, particularly if it's a mobile target,” Brown said. “Those are things I'm thinking about. It's nice to have this weapon, but I've got to have the whole thing.” The Defense Department also is working on other long-range-missile technologies. In August, Russia and the U.S. governments withdrew from the 32-year-old Intermediate-Range Nuclear Forces Treaty, allowing both countries to follow China's lead in fielding ground-launched ballistic and cruise missiles with a range of between 500 km and 5,000 km. Since August, the DOD has demonstrated a rudimentary ground-launched cruise missile and ballistic missile in flight, but a fielding decision is still pending a policy decision by the Office of the Secretary of Defense (OSD). Brown could offer no update on the status of the policy decision. “That may be a logical conclusion, but I'd refer you to OSD on where their approach is and where the department might land as far as where we're going in the future,” Brown said. https://aviationweek.com/shownews/singapore-airshow/ready-fire-aim-pacaf-chief-emphasizes-hypersonics
