The telescope is located in the Milky Way where there are a large number of stars that can be observed at one time and is located near the ecliptic where the number of the Kuiper belt objects is large (that is, it is predicted that the occultation phenomenon is likely to occur) It was. Examination of the obtained moving image data revealed that the 12th grade star in the field of view had d

The Camera Pointing System developed by PolyU expert measures 85 cm (length) by 27 cm (width) and 16 cm (depth) and it weighs 2.8 kg. It was installed in the upper part of the lander and capable of moving vertically by 120 degree and rotating sideway by 350 degree to capture images of the moon as well as movement of the rover. This sophisticated space tool will be able to withstand the vast difference in temperature and function in one sixth of gravity on the moon. After the rover is released, the Camera Pointing System will come into operation together with other parts of the lander for lunar exploration. PolyU has been working closely with CAST. In 2010, both parties signed a pact for the establishment of a Joint Laboratory in Precision Engineering for Space Applications. CAST also donated advanced space research equipment for the Joint Laboratory. In the third phase of China’s lunar exploration programme, Professor Yung will further collaborate with mainland e

 $69.90 from Amazon Includes ARM7 EJ-S™, GSM, GPRS, Wi-Fi, Bluetooth BR/EDR/BLE, GPS, Audio codec, and SD card connector on a single development board. Pin-out similar to Arduino boards, including Digital I/O, Analog I/O, PWM, I2C, SPI, UART and power supply, compatible with Arduino. Provides various interfaces for connecting to most sensors, peripherals, Groves, and other widgets. You are what you wear. Using LinkIt ONE together with MediaTek LinkIt SDK (for Arduino) you will be able to easily turn your ideas into practical prototypes and make them a reality with the Seeed productization and agile manufacturing service.  comparison between LinkIt ONE, Intel Edison, Raspberry Pi, BeagleBone Black (left to right) If you add BT, GPS and GSM into the other 3 boards, the cost is much higher than LinkIT ONE. Though the ARM on LinkIt ONE, MT2502A(launched in 2014),  is targeting the wearables market, claim to have low power consumption seen in use on No.

"In order to effectively fight against ASF, farmers involved in pig farming should strictly observe a number of principles, i.e. the so-called biosecurity, including the use of specific behaviors and hygiene measures, such as the disinfection of hands, footwear, clothing, tools or equipment used in farms "- wrote the WWF Poland Foundation in a message sent on Tuesday.(8 Jan 2019)   "The virus is transmitted from the forest on clothes, shoes or wheels of cars." Currently, where there are outbreaks of the virus, pigs do not have any direct contact with wild boars or other forest animals, because they must be permanently locked in piggies "- noted Piotr Chmielewski from WWF Poland Foundation.   "By the end of February, almost all wild boar in Poland will be killed, including young and pregnant dungeons, even animals living in national parks, together over 210,000 feral pigs! This cruel, costly, scientific and ineffective activity

China will launch the first of around 320 satellites for a planned low Earth orbit communications constellation before the end of the year, the country's main space contractor has stated. The experimental first satellite has been developed under the China Aerospace Science and Technology Corporation (CASC), which revealed last week at the 2018 Zhuhai Airshow that the launch would take place soon. The satellite will be sent into a 1,100 km altitude orbit by a Long March 2D launch vehicle to test L- and Ka-band communication capabilities and compatibility in low Earth orbit (LEO). It will be one of nine satellites orbited by 2020 as a pilot demonstration for the Hongyan system, which translates as 'wild goose'. The name likely comes from the fact that geese were used to deliver messages in ancient China. The first 60 satellites making up the first phase of deployment of the Hongyan constellation are expected to be in orbit and operational

scheduled to soft land on  Von Kármán crater on 3 Jan, 2019 Von Kármán will offer the chance to analyse the variations of composition of the lunar surface and SPA melt sheet with the Visible and Near-Infrared Imaging Spectrometer ( VNIS ), while also returning unprecedented images with cameras on both the lander and rover. A number of subsequent impact craters in the surrounding region, such as Finsen, are expected to have delivered ejecta to the floor of Von Kármán, potentially providing a rich sample of the SPA basin and far side geologic history. The Lunar Penetrating Radar (LPR) and low‐frequency radio spectrometer (LFS) payloads will also return unique data from the landing region, while the Lunar Lander Neutrons and Dosimetry ( LND ) instrument and Advanced Small Analyser for Neutrals ( ASAN ) will provide insight into the space environment and interactions with the surface. The CNSA administration said Chang’e 4’s scientific tasks included astronomica
