  Astroscale leaps into the satellite servicing fray

  Nathan Strout The American unit of Astroscale Holdings is entering the satellite life-extension market with the purchase of an Israeli company that specializes in developing on-orbit servicing solutions. Astroscale U.S. has acquired Effective Space Solutions, which develops life-extension solutions for satellites in geostationary orbit, or GEO. In addition to adding ESS' intellectual property to its portfolio, Astroscale is hiring all of the company's staff to form Astroscale Israel Ltd., which will remain in that country and serve as Astroscale's research and development group for geostationary satellite life-extension services. Astroscale, a global company based in Japan, is best known for its efforts to remove space debris from orbit. The company expects to demonstrate its end-of-life service later this year, which will see an Astroscale space vehicle capture debris and de-orbit it. But with this purchase the company is scaling up its understanding of — and ambitions for — on-orbit servicing. “Really, we've started thinking about the debris remediation part of the market as a subset of on-orbit services. It's one thing you can do once you have a satellite up there that can rendezvous and dock with other satellites,” said Ron Lopez, president and managing director of Astroscale U.S. “We're bringing all of those resources to bear to move into the GEO life-extension business, to complement what we're doing in [low Earth orbit] LEO on the debris and the situational space awareness side.” Astroscale claims that with its debris removal efforts in LEO and its new GEO life-extension effort, the company is now the only business solely dedicated to on-orbit servicing across all orbital regimes. Eventually, Astroscale could add satellite refueling, repair, upgrading, towing, salvage, situational space awareness and on-orbit manufacturing to its future portfolio for logistics services. But for now, the company is focused on providing life-extension services — supplanting the exhausted fuel reserves of a client satellite with the propulsion provided by an attached space vehicle. ESS' Space Drone platform will be used as the base for Astroscale's first life-extension vehicle. Lopez couldn't give a timeline for when the first life-extension mission would begin, stating that the timeline would be driven by customer demand. He added that he is in talks with potential customers. Astroscale will face some stiff competition as it enters the still nascent satellite-servicing market. SpaceLogistics, a Northrop Grumman subsidiary, successfully docked its own space vehicle with a commercial GEO satellite in February, marking the beginning of the first-ever commercial satellite life-extension mission. SpaceLogistics has also made important inroads with the Department of Defense. The company is working with the DoD to study the feasibility of providing life-extension services to four military satellites. And shortly after the firm's successful docking with a commercial satellite in February, the company announced it will partner with the Defense Advanced Research Projects Agency to field a pair of government-built robotic arms for on-orbit repairs. Astroscale also sees the DoD as an important customer for any GEO servicing efforts. “U.S. strategy right now is very heavily focused on space, specifically on building resiliency and achieving greater operational flexibility, which this kind of capability will allow U.S. government customers to do,” Lopez said. The company does not have any DoD contracts to date, but Lopez said it's in communication with key U.S. government stakeholders and has presented its solution to DoD representatives. Lopez also sees strong commercial interest in on-orbit servicing, which underpins the company's business plan and would allow the government to leverage commercial prices. Ultimately, Lopez believes Astroscale is well-positioned to compete. “Even though we're small, we're nimble and we have a real, meaningful global footprint,” he said. https://www.c4isrnet.com/battlefield-tech/space/2020/06/03/astroscale-leaps-into-the-satellite-servicing-fray

  NATO surveillance drones dial up flying hours, maritime sensing

  No sooner had it arrived, one of the five unmanned aircraft headed to California to be equipped with the so-called GMTI-over-Sea capability, giving it the ability to track moving maritime targets as well as moving land targets.

  China’s stealth fighter goes into mass production after thrust upgrade

  The J-20B has overcome agility problems to finally be considered a fully fledged fifth-generation fighter, military source says Aircraft still will be fitted with Russian engine but ‘Chinese version could be ready in a year or two' A modified version of China's first stealth fighter jet, the J-20, has formally entered mass production, with upgrades earning it a place as a fifth-generation fighter jet, according to a military source close to the project. The moment was marked at a ceremonial unveiling of the modified J-20B stealth fighter jet on Wednesday attended by many senior military leaders including Central Military Commission (CMC) vice-chairman General Zhang Youxia, the source said. Zhang is the second-ranked vice-chairman of the CMC and is in charge of weapons development for the People's Liberation Army. “Mass production of the J-20B started on Wednesday. It has finally become a complete stealth fighter jet, with its agility meeting the original criteria,” the source said. “The most significant change to the fighter jet is that it is now equipped with thrust vector control.” Thrust vector control (TVC) allows pilots to better control the aircraft by redirecting engine thrust. In 2018, China debuted its J-10C multirole fighter – fitted with a WS-10 Taihang engine – at the China air show in Zhuhai, putting the aircraft through its paces in a performance that indicated that China had succeeded in thrust technology. While the TVC technology had been applied to the stealth fighter, the J-20B would still use Russian Saturn AL-31 engines because more work needed to be done on China's WS-15 engine, the source said. Chinese engineers have been developing high-thrust turbofan WS-15 engines for the J-20, but that work has fallen behind schedule. “The Chinese engine designed for the J-20s still failed to meet requirements, but its development is going quite smoothly, and it may be ready in the next one or two years,” the source said. “The ultimate goal is to equip the J-20B fighter jets with domestic engines.” China was thought to have built about 50 J-20s by the end of 2019, but problems with the jets' engines delayed further production plans. Meanwhile, Lockheed Martin's Fort Worth assembly plant in Texas delivered 134 F-35 stealth fighters in 2019, three more than its target and 47 per cent more than its output in 2018, according to the company. China's first batch of J-20s entered service in 2017 when the US decided to deploy more than 100 F-35s to Japan and South Korea that year. The J-20 was meant to be a fifth-generation fighter jet on a par with Lockheed's F-22 Raptor and F-35 Lightning multirole strike fighters. Fifth-generation fighters are defined by their stealth technology, supersonic cruising speed, super manoeuvrability, and highly integrated avionics. But the earlier version of the J-20 was described by Western media as a “dedicated interceptor aircraft” because of its lack of agility. “The launch of the J-20B means this aircraft now is a formal fifth-generation fighter jet,” the military source said, adding that Chengdu Aerospace Corporation (CAC), which manufactures the J-20s, had received “heavy orders” from the PLA. CAC set up its fourth production line in 2019, each one with a capacity to make about one J-20 a month. https://www.scmp.com/news/china/military/article/3092839/chinas-stealth-fighter-goes-mass-production-after-thrust
