China luanched spacecraft to use and develop millisecond pulsar navigation
http://ift.tt/2aB80ot
In November, China launched the world's first spacecraft with a deep space x-ray navigation system. The X-ray Pulsar Navigation 1 (XPNAV 1) satellite, which the country launched on Nov. 10 aboard a solid-fueled Long March 11 rocket from the Jiuquan Space Launch Center in the Gobi Desert, is the world's first x-ray navigation system to go in orbit, beating out NASA's Station Explorer for X-ray Timing and Navigation Technology (SEXTANT), which is scheduled to be installed on the ISS next year.
Millisecond pulsars generate x-ray pulses at such short intervals, that by measuring the time differential from multiple known pulsars (like a GPS using pulsars instead of satellites), a spacecraft can determine its location in the solar system within 5 kilometers (3.1 miles), which is pretty good for deep space. The trick is to find pulsars that provide pulses at a consistent pace; x-ray pulsars often speed up or slow down the frequency of their bursts.
If all goes as planned, the XPNAV 1 will both gather data to build the pulsar x-ray database and then be able to use that data to independently verify its location. The 529-pound satellite has two detectors to measure x-rays generated by pulsars. Over the next five to ten years, XPNAV 1 will build a database of x-rays from 26 pulsars, measuring their frequencies against other electromagnetic activity in space. It will also measure the accuracy and consistency of pulsar x-rays against background space noise, without having to worry about atmospheric interference. It will verify the usability of the data by testing the data to see if the data can predict the satellite's location, independent of other navigation aids.
The advantages of x-ray navigation include greater accuracy and reliability; spacecraft wouldn't need to rely on radio signals that take longer to travel into deep space and lose signal fidelity. X-ray navigation is also cheaper, because the spacecraft would no longer need large, expensive ground-based radio antennae for navigation signals. Additionally, the spacecraft would be more autonomous, saving bandwidth for the transmission of scientific data back to earth.
Simulations made by the team provided crucial measurements regarding the future development of the XNAV method. The scientists concluded that at the distance of Neptune (about 30 astronomical units from the Earth), a 3-D location of a spacecraft with an accuracy of 18.6 miles (30 kilometers) can be calculated by locking onto three pulsars. Moreover, they estimated that even an accuracy of 1.25 miles (2 kilometers) can be achieved when locking onto a particular pulsar, called PSR B1937+21, for 10 hours. Due to the fact that PSR B1937+21 is a millisecond pulsar, completing almost 642 rotations per second, and thanks to its very stable rotation, it is capable of keeping time as well as atomic clocks.
The Neutron star Interior Composition Explorer (NICER) is an International Space Station (ISS) payload devoted to the study of neutron stars through soft X-ray timing. Neutron stars are unique environments in which all four fundamental forces of nature are simultaneously important. They squeeze more than 1.4 solar masses into a city-size volume, giving rise to the highest stable densities known anywhere. The nature of matter under these conditions is a decades-old unsolved problem, one most directly addressed with measurements of the masses and, especially, radii of neutron stars to high precision (i.e., better than 10 percent uncertainty). With few such constraints forthcoming from observations, theory has advanced a host of models to describe the physics governing neutron star interiors; these models can be tested with astrophysical observations.
From NICER's ISS platform, a star-tracker-based pointing system allows the XTI to point to and track celestial targets over nearly a full hemisphere. The pointing system design accommodates the ISS vibration and contamination environments, and enables (together with NICER's GPS-based absolute timing) high-precision pulsar light-curve measurements through ultra-deep exposures spanning the 18-month mission lifetime. Anticipated launch of NICER is in early 2017.

China plans space missions to dark side of the moon and Mars and beyond
http://ift.tt/2aB80ot
China's ambitious and fast-growing space program is targeting a landing on the dark side of the moon by 2018, and reaching Mars before the end of the decade.
China's space agency held a press conference on Tuesday to mark the release of a policy paper, and outlined the government's goals for exploring deep space.
Wu Yanhua, deputy chief of the National Space Administration, said Beijing aims to launch its first Mars probe around 2020 to carry out orbiting and roving exploration, followed by a second mission that would include collection of surface samples from the red planet.
China launched an ion drive HEP-100MF thruster. It was jointly developed by research teams from the Harbin Institute of Technology (H.I.T.) and the China Academy of Space Technology's (CAST) Institute 502, successfully debuted Nov. 22 aboard an orbiting Shijian-17 satellite. The satellite was launched Nov. 3 by a Long March 5 rocket. This will be used for deep space missions.
China plans include sending probes to Jupiter and its moons. By around 2030, China hopes to be more competitive with NASA's deep space program.

China has test flight of an improved FC-31 Gyrfalcon stealth fighter
http://ift.tt/2aB80ot
China has tested the latest version of its fifth-generation J-31 stealth fighter The newest version of the J-31, now renamed the FC-31 Gyrfalcon, took to the air for the first time on Friday, the China Daily reported.
The new FC-31 has “better stealth capabilities, improved electronic equipment and a larger payload capacity” than the previous version which debuted in October 2012, the newspaper said, quoting aviation expert Wu Peixin.
“Changes were made to the airframe, wings and vertical tails which make it leaner, lighter and more manoeuvrable,” Wu told the paper.
The FC-31 Gyrfalcon can carry 8 tons of weapons The FC-31 has a maximum take-off weight of 28 metric tons, a flight radius of 1,250 km, and a top speed of Mach 1.8 or 1.8 times the speed of sound. The aircraft can easily carry 8 tons of weapons, holding six missiles in its internal weapons bay, plus six more under its wings.
Sergey Kornev, head of Russia's Air Force Equipment Export Department, earlier told RIA Novosti the J-31 will fly on Russian aircraft engines RD-93.
The jet is manufactured by Shenyang Aircraft Corp, a subsidiary of the Aviation Industry Corp of China.
The fighter will be exported to other countries is expected to sell for about US$70 million, the article said, aiming to take market share away from more expensive fourth-generation fighters like the Eurofighter Typhoon.
The Chengdu J-20 twin-engine stealth fighter bears similarity to the F-22 Raptor made by Lockheed Martin Corp., while the Shenyang J-31 twin-engine multi-role fighter resembles the F-35 Joint Strike Fighter design also made by Lockheed.
In the 1960s, China worked from the blueprints and other materials, and eventually produced the J-7, a virtual copy of the Soviet MiG-21. The Chinese eventually sold the J-7 (F-7 export variant) in direct competition with the MiGs sold by the Soviets. Indeed, after the US-PRC rapprochement of the early 1970s, the Chinese sold J-7s directly to the Americans, who used them as part of an aggressor squadron to train US pilots to fight the Soviets.
In the 1990s there were several huge arms deals between Moscow and Beijing. One of the most important involved the sale, licensing, and technology transfer of the Su-27 “Flanker” multirole fighter. The deal gave the Chinese one of the world’s most dangerous air superiority fighters, and gave the Russian aviation industry a lifeline. China produced the J-11 as a copy of the Su-27.
Americans analysts suspected that China was stealing information associated with the F-35. The Snowden leaks confirmed extensive Chinese industrial espionage. The likely reality of this theft became clear when information about the J-31 stealth fighter became available. The J-31 looks very much like a twin-engine F-35, without the VSTOL capabilities of the F-35B.

Jerry Pournelle talks about China's orbital tests of the EMDrive as a bigger than Sputnik moment
http://ift.tt/2aB80ot
Jerry Pournelle is a famed science fiction author who also had an interesting technology career
Jerry Eugene Pournelle (born August 7, 1933) is an American science fiction writer, essayist and journalist who contributed for many years to the computer magazine Byte. Pournelle was an intellectual protégé of Russell Kirk and Stefan T. Possony. Pournelle wrote numerous publications with Possony, including The Strategy of Technology (1970). The Strategy has been used as a textbook at the United States Military Academy (West Point), the United States Air Force Academy (Colorado Springs), the Air War College, and the National War College.
Pournelle worked in the aerospace industry includes time he worked at Boeing in the late-1950s. While there, he worked on Project Thor, conceiving of "hypervelocity rod bundles", also known as "rods from God". He edited Project 75, a 1964 study of 1975 defense requirements. He worked in operations research at The Aerospace Corporation, and North American Rockwell Space Division, and was founding President of the Pepperdine Research Institute. In 1989, Pournelle, Max Hunter, and retired Army Lieutenant General Daniel O. Graham made a presentation to then Vice President Dan Quayle promoting development of the DC-X rocket.
Jerry says, the question becomes, given the magnitude of this, why is it a surprise? We have 21 expensive intelligence agencies; not one of them knew the Chinese orbited an EM Drive? Of course it will be a while before we can do orbital tests. We have no rockets. That’s preparedness. Perhaps Elon Musk or Jeff Bezos can help? This is a signal larger than Sputnik. If the Intelligence Community knows about Russian hacking, why doesn’t it know about Chinese testing of a reactionless drive?
Nextbigfuture has covered the EMDrive and the propellentless Cannae drive
China's space agency has officially confirmed that it has been funding research into the controversial space propulsion technology EmDrive, and that it plans to add the technology to Chinese satellites imminently.
The China Academy of Space Technology (CAST), a subsidiary of the Chinese Aerospace Science and Technology Corporation (CASC) and the manufacturer of the Dong Fang Hong satellites, has held a press conference in Beijing explaining the importance of the EmDrive research and summarizing what China is doing to move the technology forward.
China Academy of Space Technology (CAST) team statements corresponds with information provided to IB Times from an anonymous source. According to their informant, China already has an EM Drive on board its version of the International Space Station, the space laboratory Tiangong-2.
Chinese researchers have at least constructed an EM Drive and have been studying it for more than five years now.
Chief designer of the CAST communication satellite division, Li Feng, told the media that so far their EM Drive only produces millinewtons of thrust (similar to NASA's version) and to make it functional, they need to get those levels up to between 100 millinewtons and 1 newton.
The team is allegedly now working on the cavity design of the EM Drive and the position of the thruster, before testing their new versions on their satellites in orbit.
Logically if an EMDrive was placed on Tiangong-2 and no thrust was produced, this would be apparent right away. If tiny thrust was produced in orbit and in a vacuum then further research would be pursued. Further research could still occur if thrust seemed to be produced on the ground but did not appear in orbital microgravity. However in the case of no result in orbit, then the CAST team would probably not hold a press conference.
"This technology is currently in the latter stages of the proof-of-principle phase, with the goal of making the technology available in satellite engineering as quickly as possible," Li Feng explained at the press conference.
"Although it is difficult to do this, we have the confidence that we will succeed."
