CBERS-4A: New China-Brazil earth resource satellite launched into space

The China-Brazil Earth Resource Satellite-4A (CBERS-4A), a new satellite jointly developed by China and Brazil as part of a bilateral program, was recently sent into space, thus further pushes forward the aerospace cooperation between two countries. It was launched on a Long March-4B carrier from the Taiyuan Satellite Launch Center in Shanxi Province of China. The same rocket also put into orbits another 8 satellites, including a wide-range multispectral remote-sensing microsatellite donated to Ethiopia (which is also Ethiopia’s first satellite).

About China-Brazil Earth Resource Satellite-4A (CBERS-4A)

CBERS-4A is equipped with 3 optical payloads:- a wide-range panchromatic multispectral camera developed by China, and a wide-field imager and a multispectral camera developed by Brazil. It will obtain global optical remote-sensing data and will also support the Brazilian government to monitor the Amazon rainforest and changes in the country’s environment.

It will also be used in fields such as earth resource monitoring, agriculture, environmental protection, meteorology, surveying, and mapping, and serve Brazil and more developing countries. It can also provide services for African, Latin American and Asian countries

The satellite was jointly developed by the China Academy of Space Technology (CAST) and National Institute for Space Research (NISR) of Brazil, while the carrier rocket was developed by the Shanghai Academy of Spaceflight Technology.

Background: CBERS-4A will replace CBERS-4 (which was launched in 2014), to improve the resolution of remote-sensing data. The satellite is a 6th satellite under earth resource satellite cooperation program between two countries that began in 1988. The satellites designed under the program are for Earth observation from orbit for non-military use and first, such earth research satellite was launched from China in 1999.

NOTE: The China and Brazil bilateral program is also seen as a template for broader cooperation among both countries as well as Russia, India and South Africa (i.e. BRICS nation overall). Currently, only South Africa in BRICS bloc does not have satellites of its own.

Artificial intelligence Artificial intelligence (AI) is the simulation of human intelligence processes by machines, particularly computers. Typical applications of AI include expert systems natural language processing (NLP), speech recognition, machine vision and many more. AI programming focuses on three cognitive skills: learning, reasoning, and self-improvement. Learning process . This aspect of AI programming focuses on obtaining data and creating rules to convert data into actionable information. The rules called algorithms, provide computing devices with step-by-step instructions to accomplish a specific task . The process of reasoning. This aspect of AI programming focuses on choosing the right algorithm to reach the desired result. Processes of self-improvement. This aspect of AI programming is designed for consistently fine algorithms and ensures that they provide the most accurate results possible. Advantages and disadvantages of artific

5 Jobs that AI can replace in the next ten years

5 Jobs that AI can replace in the next ten years 1. Customer relationship advisor The emerging chatbots have redefined the experience of customer care. The probability of all telemarketing jobs getting replaced by AI is the highest. One of the major reasons behind this is efficiency. AI-enabled chatbots are considered more efficient than human resource-driven customer care services. 2. Programming language trainer All the IT firms employ a training consultant for various functions. The job of a programming language trainer is already on its way out. Employees prefer e-learning services over the human trainer. AI-driven interactive training solutions are likely to replace the job of programming language trainers. 3.
