Washington, Oct. 28 (Xinhua/UNB) -- The Hubble Space Telescope returned to normal operations with three fully functional gyroscopes late Friday and completed its first science observations on Saturday, The National Aeronautics and Space Administration (NASA) said.
The recovery came after engineers successfully fixed a backup gyroscope that had replaced a failed one three weeks earlier, NASA said in a statement.
However, the backup incorrectly returned rotation rates that were far in excess of the actual rates.
Last week, the space telescope's operations team commanded Hubble to perform numerous maneuvers and switched the gyroscope between different operational modes, which successfully cleared what was believed to be blockage between components inside the gyroscope that produced the excessively high rate values, NASA said.
The team then monitored and tested the gyroscope with additional maneuvers to ensure its stability.
By late Friday, Hubble successfully completed maneuvers to get on target for the first science observations and collected its first science data since Oct. 5, NASA said.
A gyroscope is a device that measures the speed at which the spacecraft is turning, which is necessary to help Hubble turn and lock on to new targets.
Originally required to last 15 years, Hubble has now been at the forefront of scientific discovery for more than 28 years. The team expects the telescope will continue to yield amazing discoveries well into the next decade.
Tokyo, Oct 29 (AP/UNB) — A Japanese rocket on Monday lifted the United Arab Emirates' first locally made satellite into orbit successfully from a space center in southern Japan.
The KhalifaSat Earth observation satellite was launched by the Japan Aerospace Exploration Agency and Mitsubishi Heavy Industries from the Tanegashima Space Center.
The H-2A rocket also is carrying an Ibuki-2 greenhouse gas observation satellite for Japan.
Both the KhalifaSat and Ibuki-2 have since been released separately into targeted orbit, said MHI Launch Services.
The launch marks progress in the Gulf nation's fledging space program.
The country aims to send its first two astronauts to the International Space Station in 2019. The UAE also aims to send a probe on its way to Mars in 2020 and to build a science city there by 2117.
Japan also aims to expand its commercial satellite launch services by Mitsubishi Heavy Industries and make them globally competitive.
Jiuquan, Oct 29 (Xinhua/UNB) -- China sent an ocean-observing satellite successfully into space on Monday, a joint mission pursued under close Sino-French space cooperation that will enable scientists to study, for the first time, ocean surface winds and waves simultaneously.
The China-France Oceanography Satellite (CFOSat), atop a Long March-2C carrier rocket, took off at 8:43 a.m. from Jiuquan Satellite Launch Center, in northwest China's Gobi Desert, and entered a sun-synchronous orbit 520 km above the Earth.
Jointly developed by the China National Space Administration (CNSA) and the Centre National d'Etudes Spatiales, the French space agency, the satellite will conduct 24-hour observations of global wave spectrum, effective wave height, and ocean surface wind field, said Zhao Jian, a senior official with CNSA.
As the first satellite cooperation between China and France, the CFOSat is equipped with the world's most advanced technologies.
It carries two innovative radar instruments -- a wind scatterometer developed by China to measure the strength and direction of winds and a wave spectrometer developed by France to survey the length, height, and direction of waves, according to Wang Lili, chief designer of the satellite with the China Academy of Space Technology.
The two instruments will help scientists collect data about winds and waves of the same location simultaneously for the first time, Wang said.
Winds generate waves, and waves, in turn, modify the surface layer of the atmosphere above the ocean. Therefore, more and more often, meteorological and wave forecasts take into consideration the modeling and prediction of both ocean surface winds and waves.
Related forecasts have been enhanced significantly in the last decade, but the prediction accuracy still needs to be improved, especially in extreme events, such as hurricanes, typhoons, and rapidly evolving storms.
The CFOSat, complementing other existing oceanography satellites, will study the dynamics of waves and how they interact with surface winds, and deepen our understanding of their formation and physical mechanism, said Zhao Jian with CNSA.
"It will help increase the observation and prediction of catastrophic sea states, such as huge waves and tropical storms, and provide security support for offshore operations and engineering, ship navigation, fisheries, and coastal management," Zhao said.
By gaining new insights into the impacts of winds and waves on the atmosphere-ocean exchanges that play a key role in the climate system, the satellite will also provide basic information for global climate change research, he added.
China has previously launched six oceanic satellites, with the first officially approved to be developed in 1997. Two other satellites, the HY-1C and the HY-2B, were also sent into space this year ahead of the CFOSat.
"There are now five China-developed oceanic satellites in orbit, each having its own strength in monitoring ocean color, dynamics or sea states. They will complement each other and form a comprehensive observation network to continuously cover the global oceans for various statistics and with high resolution," Zhao said.
"The data they acquire, of remarkable social and economic benefits, will play an important role in protecting ocean environments, exploiting marine resources, preventing and reducing marine disasters, as well as improving marine science research," he said.
Beijing, Oct 28 (AP/UNB) — The first attempt by a private Chinese company to send a rocket into space has failed.
Beijing-based Landscape said late Saturday that the first and second stage of its ZQ-1 rocket worked normally but something went wrong with the final of the three-stage rocket.
It was the first three-stage rocket built by a private company in China.
Video posted by a Chinese news site shows the 19-meter- (62-foot-) tall red-and-white rocket lifting off Saturday against clear blue skies.
Landscape said that "cowling separation was normal but something abnormal happened after the second stage." The statement posted on its social media account did not elaborate.
Chinese media reports say the rocket was carrying a satellite for state broadcaster CCTV.
Dhaka, Oct 27 (UNB) - Bangladesh’s Leading technology and smartphone manufacturing company Huawei will launch its next flagship phone, the Huawei Mate 20 Series, in Bangladesh soon.
Huawei Consumer Business Group (BG) unveiled one of the most highly anticipated smartphone series of the year at an event in Shanghai in China on Friday after its first launch in London.
The company expects the new phone will be one of the most popular smartphones. The latest version of modern Android 9 operating system has been used in the phone, on which consumers can enjoy all productivity and entertainment features easily and conveniently with a few simple taps and swipes.
The HUAWEI Mate 20 Series is powered by Huawei’s densest and highest performing system on chip to date—the Kirin 980. The devices are available in 6.53-inch, 6.39-inch and 7.2-inch sizes with full OLED screens. Out of different four configurations, the minimum RAM is 512 GB and ROM is 6GB.
Besides superb performance, the HUAWEI Mate 20 Series also features groundbreaking improvement on battery life. The HUAWEI Mate 20 Pro houses a large, high-density 4200 mAh battery, and supports 40 W HUAWEI Super Charge, which gives the device 70 percent charge in 30 minutes. The safety of the technology is certified by Germany’s TÜV Rheinland.
The Mate 20 Series have three rear cameras. Of these, one has 40 mega pixel. Other two have 8 mega pixel telephoto and 20 mega pixel Ultra Wide Angle Lens.Overall, the device will have from 16 to 270 mile miter zoom lens advantages while taking photo. This wider perspective creates a sense of spaciousness and a three dimensional effect to the images.
Huwaei also introduces new AI features that enable the HUAWEI Mate 20 Series to perform or enhance a range of tasks from object identification to food calorie counting. Using 3D Live Object Modeling, consumers can even create a fun digital avatar to dance or interact with.
The Mate 20 Series have changes in designs too. Its screen size is bigger than previous phones. Finger print facility will be floated on the screen, which was absence in previous devices. Consumers will be able to unlock the phones using 3D photo identification technology and bone ID ( voice recognition) .
