Tiangong-1 is China’s first prototype space station, scientists says the space station is expected to re-enter the atmosphere and crash into Earth within weeks.
Tiangong-1 (In English it means Heavenly Palace ) is China’s first prototype space station, serving as both a manned laboratory and an experimental testbed to demonstrate orbital rendezvous and docking capabilities. It was originally intended to be launched in August 2011, however following the failed launch of a Long March 2C rocket in August 2011, the launch was postponed. On 20 September 2011, the spacecraft was again rolled out for the rescheduled launch attempt and on 29 September, 2011 successfully placing Tiangong-1 into low Earth orbit.
China lost control over Tiangong-1 on March 16, 2016 and would be unable to perform a controlled re-entry. It is believed that the space station ceased functioning due to a dysfunctional battery charger. In January 2018, The Aerospace Corporation predicted the Tiangong-1 will likely re-enter the Earth’s atmosphere sometime within weeks, during March 2018. However scientists says it is impossible to plot where space station will re-enter the atmosphere, but the chance is higher in parts of Europe, US, Australia and New Zealand. Some experts says India, mainly Kerala is also in the range for re-enter the space station.
Since the size toe spacecraft is big and according to experts, there are chance that it will do damage, while re-enter in to earth. It might hit someones roof, or there will be a rain of a few pieces of metal, but it is not widespread damage.
According to US Aerospace Corporation, they are estimating that the space station will re-enter the atmosphere during the first week of April. But the European Space Agency says the module will come down between 24 March and 19 April.
The space station weighs 8.5 tonnes and is only about 34.1 feet in length and 11 feet in diameter.
The Department of Telecom (DoT) has issued instructions to all telecom operators to start using 13 digit mobile numbers for all existing Machine-to-Machine (M2M) customers. After reading this message, many of them has posted rumors on social media that normal retail mobile numbers would also be shifted to 13-digit mobile numbers which is untrue. Here I am trying a small effort that what is M2M communication and its applications
M2M refers to ‘non-human’ communication. Machine-to-Machine (M2M) communication is a form of data communication that involves one or more entities that do not necessarily require human interaction or intervention in the process of communication. M2M is also named as Machine Type Communication (MTC) in 3GPP.
M2M communication could be carried over mobile networks (e.g. GSM-GPRS, CDMA EVDO networks). In the M2M communication, the role of mobile network is largely confined to serve as a transport network
Applications of M2M
The applications of M2M cover many areas and the areas in which M2M is currently used are given below:
- Security : Surveillances, Alarm systems, Access control, Car/driver security
- Tracking & Tracing : Fleet Management, Order Management, Pay as you drive, Asset Tracking, Navigation, Traffic information, Road tolling, Traffic optimization/steering
- Payment : Point of sales, Vending machines, Gaming machines
- Health : Monitoring vital signs, Supporting the aged or handicapped, Web Access Telemedicine points, Remote diagnostics
- Remote Maintenance/Control :Sensors, Lighting, Pumps, Valves, Elevator control, Vending machine control, Vehicle diagnostics
- Metering : Power, Gas, Water, Heating, Grid control, Industrial metering
- Manufacturing : Production chain monitoring and automation
- Facility Management : Home / building / campus automation
Human trafficking is the third largest international crime industry and a global threat. Eevery year, millions of men, women, and children are trafficked in countries around the world. Libya is the new hub for human trafficking.
Libya is the main gateway for people attempting to reach Europe by sea. According to the estimation, each year, more than 150000 people crossing the border, from the last three years.
Libya is a country with 1,100-mile coastline has effectively become an open border without government forces to monitor who comes and who goes. Smugglers have filled the void, willing to tightly pack hundreds of migrants at a time into flimsy vessels and shuttle them to Italy.
Refugees and Migrants from many north and west African countries like Ghana, Nigeria, Cameroon, Zambia, Senegal, Gambia and Sudan, who dreamed for better lives, take risk to cross the sea border to reach European countries. They are smuggled into Libya by a network of criminal gangs on the promise of reaching Europe’s shores for better opportunities. But they are not know the cheating happing in their journey end.
As per the International Organization for Migration (IOM), when they arrived at Libya border, the migrant were beaten up and forced to call their families to arrange money for their release. Some of those who cannot pay their captors are reportedly killed or left to starve to death, the IOM said. When migrants die or are released, others are purchased to replace them.
A survivors have told to to UN’s Migration agency that , people are then allegedly sold off like goods in an open market. Smugglers, they use smart phones to connect with people smugglers to get them to Libya’s coast, and that they were then sold, being held for ransom, used as forced labour or for sexual exploitation.
The footage released by CNN appears to show youths from Niger and other sub-Saharan countries being sold to buyers for about $400 (£300) at undisclosed locations in Libya.
CNN also reported that Libya has opened an investigation into the practice…
This issue should reach global attention and UN must interfere the matter.
