Russian state news media and credible western news outlets such as the BBC World News are reporting that Russia has operationally deployed its new, “highly maneuverable”, ICBM-launched Avangard Hypersonic Glide Vehicle to an active military base somewhere in the Ural Mountains of western Russia.The reports are significant since the Russian claims of maneuverability for the Avangard HGV may make interception of the missile system impossible with known anti-missile defense systems and countermeasures.The Avangard is boosted into flight using an ICBM launch platform such as Russia’s SS-19 Stiletto (also known as the UR-100UTTkh). The Avangard HGV separates from its ICBM boost platform after reaching an apogee or maximum altitude of approximately 100 km. After separation from the launch ICBM platform the unpowered Avangard reenters the atmosphere at hypersonic speed. This flight profile is no different than existing ICBM deployed hypersonic weapons used by the U.S. and other nations. What is claimed to set the Avangard apart from existing reentry vehicles is its maneuverability. Russia claims the Avangard is as fast as an ICBM warhead on reentry but also as maneuverable as a low-speed cruise missile. It is this claim of maneuverability at hypersonic speeds that is alleged to make Avangard “impossible” to intercept by known anti-missile defense systems.

One person was killed and about a dozen injured when Russian aircraft carrier Admiral Kuznetsov caught fire at a Murmansk shipyard renovating the warship, international media outlets have reported.
A source told the Russian government-owned TASS news agency that one body was found at the site of the fire, 12 people were being treated for injuries, and two more people remained unaccounted for. Those that were being treated for injuries were mostly suffering from inhaling toxic fumes from the fire, including burning diesel fuel.
The fire may have started due to violations of safety protocol while workers conducted welding on the ship, TASS reported. Russian government-owned outlet Sputnik cited the head of the United Shipbuilding Corporation (USC), Alexei Rakhmanov, as saying the fire broke out during welding work near the first energy compartment, when a spark fell into a hold space where fuel was handled.
NASA gave its approval Dec. 12 to proceed with the launch later this month of Boeing’s CST-100 Starliner commercial crew spacecraft on an uncrewed test flight to the International Space Station.At the end of a Flight Readiness Review at the Kennedy Space Center, NASA officials approved plans to launch the Starliner on its Orbital Flight Test (OFT) mission on a United Launch Alliance Atlas 5 at 6:36 a.m. Eastern Dec. 20. A launch on that day would result in the spacecraft docking with the ISS a little more than a day later, remaining there for nearly a week before landing at White Sands Missile Range in New Mexico in the predawn hours of Dec. 28.“I’m happy to announce we’re go for launch,” NASA Deputy Administrator Jim Morhard said in a media teleconference shortly after the review concluded.
The DF-17, China's hypersonic missile that was first revealed at the National Day military parade on October 1, might not be the only hypersonic aircraft program China possesses, a report by the state broadcaster suggested.Analysts stressed that China will not fall behind in related technologies compared with the US and Russia."From the test subjects that were made available to the public, the Xingkong-2 (Starry Sky-2) might use a different flight pattern to the DF-17," said military expert Ma Jun on Military Time, a China Central Television (CCTV) program on military affairs, on Saturday, without further elaboration.According to Ma, the Xingkong-2 is still in the trial phase and more tests are expected.The Xingkong-2 Ma referred to is the first Chinese waverider hypersonic vehicle unveiled by the country, dating a year earlier than the DF-17.Designed by the China Academy of Aerospace Aerodynamics under the China Aerospace Science and Technology Corporation, the Xingkong-2 was successfully tested at a target range in Northwest China in August 2018, the academy announced then.When the DF-17 missile made its debut at the National Day parade this year, some thought it might be the final product of the Xingkong-2 project.One distinctive difference between the Xingkong-2 and the DF-17 is that the former has a fairing and the latter does not, making the two very different in appearance alone, analysts pointed out.They noted that the time does not match either, as the Xingkong-2 was only tested in 2018 and is not likely to enter Chinese military service as early as 2019.The CCTV program introduced two genres of hypersonic aircraft: one is a glide-boost, meaning the aircraft is propelled into the sky via a rocket and glides in the air using shock waves generated by its own hypersonic flight, while the other is air-breathing, meaning the aircraft uses a scramjet engine to provide thrust.
Getting a probe safely to the surface of Mars is not easy: Numerous landing attempts have crashed. Sufficiently slowing a lander in the thin air requires plenty of sophisticated kit, including designer heat shields, powerful retrorockets, and, sometimes, giant airbags. But the European-Russian ExoMars mission is struggling with a bit of technology that hails from the 18th century: parachutes. High-altitude tests earlier this year revealed that ExoMars's chutes were tearing as they were pulled from their bags. The European Space Agency has turned to NASA colleagues for help, and this week, a joint team begins tests to see whether redesigned bags and chutes now work, and if not, why. It could be their last chance to fix the problem and preserve a launch scheduled for July 2020—or face another 2 years of delay.
Russia says that a U.S. team has had a chance to inspect one of its new silo-launched Avangard hypersonic missiles under the terms of the New Strategic Arms Reduction Treaty, or New START. This comes as there are mounting questions about the future of that bilateral agreement, which could sunset in 2021 unless American and Russian officials agree to an extension.The Russian Ministry of Defense announced that the inspection had occurred in a statement on Nov. 26, 2019. American personnel had first arrived for the visit two days earlier. Previous reports said that Russia had placed the first two operational examples of Avangard in silos sometime earlier in the month and that the weapon system would reach its initial operational capability in December.
China is planning a Voyager-like mission to the outer solar system that includes a flyby of Neptune, measurements of the electrically charged gas bubble surrounding our solar system, and a journey to interstellar space.The mission is currently named IHP, which stands for Interstellar Heliosphere Probe. It consists of two spacecraft that would explore the heliosphere, the solar-wind-created region around our Sun that separates us from interstellar space as the solar system travels through the Milky Way.Zong Qiugang, the director of the Institute of Space Physics and Applied Technology at Peking University in China, said the mission “will allow us to discover, explore, and understand fundamental astrophysical processes in the largest plasma laboratory—the heliosphere.” Zong gave an overview of the mission at EPSC-DPS 2019, an international gathering of planetary scientists in Geneva, Switzerland.The first spacecraft, IHP-1, would launch towards the head of the heliosphere in 2024. A second probe, IHP-2, would go in the opposite direction to explore the tail. The heliosphere is hypothesized to resemble a comet’s tail, but whether or not the tail “closes” behind the Sun is an open question. The Voyagers exited the heliosphere on the head side, and the tail has never been explored.
The Russian community of geneticists, clinicians and bioethicists have reached a consensus on the use of genome-editing technologies on human embryos and germ cells for clinical purposes. They consider that such experiments are premature at this point. Their view aligns with the position of the Russian ministry of health and sets the social context for further discussion of the technology.
China’s first domestically-built aircraft carrier is on its way to the South China Sea for tests and to take part in exercises, the Chinese navy said on Monday, after sailing through the Taiwan Strait in a mission denounced by Taipei as intimidation.Taiwan’s defense ministry said on Sunday a Chinese carrier group led by the ship passed through the sensitive strait with U.S. and Japanese vessels tailing it.Self-ruled Taiwan, regarded by China as a wayward province, said Beijing was trying to intimidate the island ahead of a presidential election in January.
Aerojet Rocketdyne and NASA recently demonstrated an Advanced Electric Propulsion System (AEPS) thruster at full power for the first time, achieving an important program milestone. Aerojet Rocketdyne-developed AEPS thrusters are slated to be used on the Power and Propulsion Element of NASA’s Gateway, the agency’s orbiting lunar outpost for robotic and human exploration operations in deep space.The state-of-the-art AEPS Hall thruster operated at 12.5 kilowatts (kW) as part of its final conditioning sequence during testing at the Jet Propulsion Laboratory in Pasadena, California. The thruster demonstrated stable operation at power levels ranging from 4.2 kW to 12.5 kW. Full electric propulsion thruster string integration will take place early next year.“Our AEPS thruster has demonstrated the high levels of power needed to operate the Power and Propulsion Element, and by extension, the entire Gateway,” said Aerojet Rocketdyne CEO and President Eileen Drake. “With a successful full power test complete, Aerojet Rocketdyne is ready for the next phase of our advanced electric propulsion system in support of NASA’s Artemis program.”The Gateway’s Power and Propulsion Element is a high-power solar electric propulsion spacecraft capable of producing 60 kW – which is three times more powerful than current capabilities. Two Aerojet Rocketdyne AEPS thruster strings will be employed on the spacecraft. Each string is comprised of a Xenon Hall thruster, a power processing unit that controls the electric power to the thruster, and a Xenon flow controller which controls the flow of Xenon to the thruster.
Russian President Vladimir Putin and German Chancellor Angela Merkel agreed on Monday that Ukraine should give its separatist-led Donbass region a special status set out in Ukrainian law, the Kremlin said.It gave no further details of the leaders’ discussions on the future of Donbass during a phone call, but agreement on its status would be a step toward convening a four-nation summit on ending five years of conflict in the eastern region.Ukrainian President Volodymr Zelenskiy said last month that Kiev had agreed to grant Donbass special status and let local elections go ahead there. The breakthrough raised hopes that a date would be set for the summit involving Kiev, Moscow, Berlin and Paris.
