Bangladesh will Launch an Earth Observation Satellite

Work is underway to start work on Bangladesh's second artificial satellite very soon after it is finalized. The country's second satellite after Bangabandhu-1 will be an 'Earth Observation Satellite', which will help in surveying the vast oceans, including surveying the country's crop production and flood situation by taking live pictures of the land surface. Bangladesh Communication Satellite Company Limited - BCSCL, hopes that the government will be able to launch the country's second satellite in the current term. The government is considering buying and launching this satellite in the G2G (Government-to-Government) process.

Earth Observation Satellites are used to take pictures of different parts of the Earth's surface and to observe the Earth's surface. The country's first commercial satellite Bangabandhu-1 is a 'geostationary communication' satellite, which is only used for communication.

The BCSCL chairman said, “An agreement was reached with the French consulting firm Price-Water House Coopers for the launch of the country's second satellite. Based on the report of the consulting firm, we have decided that the second satellite will be Earth Observation Satellite." He said the satellite would provide various benefits, adding that it would help monitor the country's crop production, flood monitoring and monitoring the country's vast oceans.

Apart from working in the country, there is also an opportunity to earn money with this satellite. As the Middle East and Africa will be covered by the satellite, it will be possible to earn income by selling various data from those areas. Because not all countries have this type of satellite. In addition to geostationary communication satellites, there are different satellites for various purposes including communication, remote sensing, navigation, geocentric orbit type, polar satellites.

The main consultant for the design of the system of the country's first artificial satellite Bangabandhu-1 was the US-based 'Space Partnership International'. After that, the satellite system was bought from the French company Talis Elenia Space under a contract worth Tk 1,951.85 crore. On 12 May 2018, the Bangabandhu-1 satellite launched from the launch pad of the Kennedy Space Center in Cape Canaveral, Florida, USA. Bangladesh is the 57th country to launch a satellite. Six months after its launch, in November 2018, Bangladesh fully acquired the ownership and control of Bangabandhu Satellite-1.

The cost of launching this time will be less than what was spent to launch Bangabandhu-1. There will be no cost after the launch of the second one. It will not be necessary to rent orbital slots. It will not be too high above the surface. The cost of renting the slot will be saved. It is also called LEO or Low Earth Orbit Satellite (LEO satellite).

Bangabandhu-1 was located 36,000 km away from the launch site. Bangabandhu-1 satellite is addressed in an orbital slot at 119.1 East longitude. Bangladesh has leased the slot from the Moscow-based Inter-sputnik International Organization of Space Communications for 45 years.

China Plans to Establish Economic Zone on the Moon

China is planning to establish an economic zone on the moon. The country will make connection between the economic zones from the earth to the moon by the 2050. Earth based Economies are not may be so much enough as China has high ambitious, that’s why they have planned to extend their economy on the Moon. The project could bring in around $10 trillion. Many netizens were thrilled by the news.

Space Scholars says that China can gain a lot, such as developing the space travel industry or conducting experiments on the moon. Bao Weimin, head of the China Science and Technology Commission, said that the new zone will cover areas of space near Earth, the Moon, and in between. The China Aerospace Science and Technology Corporation (CASC) will implement the project as part of China's National Space Program.

Bao said that such project is very economical because low cost space based communication will be developed. He also said that the construction of the core technology will be completed within the year of 2030. And they will be able to invent easier communication technology to the moon by the year 2040. By the middle of this century China is dreaming to start full production in this new economic zone on the Lunar space.

Recently, China has been conducting extensive research and survey programs based on space. Last July, a Chinese private company i-Space successfully launched a rocket. Last year, a China Lunar Rover landed successfully on the surface of the Moon.

In the year 2016, the deputy commander-in-chief of China's manned space program Zhang Yulin told to media that they had plans to explore Earth-moon space. In May 2018, China launched a relay satellite to set up a communications link between the Earth and then planned Chang'e-4 lunar probe.

China is moving fast forward day by day in the field of Space research and technology. The CASC is dedicating itself to establish China as a super power on the space, continuously carrying out the national major scientific and technical programs such as Manned Spaceflight, Lunar Exploration, Beidou Navigation and High-Resolution Earth Observation System.

Peoples need to wait and see what China is going to do in the near future.

Thanks,

Rover Curiosity Identified Methane Gas on Mars | Symbol of Life !

Is there a possibility to find any symbol of life in the red planet MARS? At least NASA's recent report indicated that. Astronomers have discovered from the report sent by the spacecraft Curiosity Rover on last week. The report said that the red planet has high levels of methane gas on its atmosphere and everybody was just surprised.

Because the methane gas in the earth is emitted by living organisms. Scientists have received the information sent by Mars Rover Curiosity on 20^th June 2019. Then on next day they researched a lot based on that information and become excited.

Though any kind of official announcement regarding this matter has not yet been finalized yet by NASA.

"With these new findings, Mars is telling us to stay the course and keep searching for evidence of life," said Thomas Zurbuchen, associate administrator for the Science Mission Directorate at NASA Headquarters, in Washington. "I'm confident that our ongoing and planned missions will unlock even more breathtaking discoveries on the Red Planet."

So far, they are continuing various experiments and testing’s. Curiosity has sent some new information on about atmosphere of Mars. The researchers and scientists have become more enthusiastic. The test report based on this matter may come next week.

Scientists say that if there is methane gas in the air of Mars in a very small scale. That means the methane found on the atmosphere is emitted very recent.

"Curiosity has not determined the source of the organic molecules," said Jen Eigenbrode of NASA's Goddard Space Flight Center in Greenbelt, Maryland, who is lead author of one of the two new Science papers. "Whether it holds a record of ancient life, was food for life, or has existed in the absence of life, organic matter in Martian materials holds chemical clues to planetary conditions and processes."

The Methozen is present in any place on the earth where there is a lack of oxygen. Such as in underground stoneware or in animal stomach. The animals leave the methane as the body's waste.

However, the methane formation sometimes happens in geothermal reaction, scientists think. They think, maybe Mars's methane found in the Curiosity test has many antiquities which was buried under stones for several thousand of years. Suddenly it broke out.

"This is the first time we've seen something repeatable in the methane story, so it offers us a handle in understanding it," said Chris Webster of NASA's Jet Propulsion Laboratory in Pasadena, California, lead author of the second paper. "This is all possible because of Curiosity's longevity. The long duration has allowed us to see the patterns in this seasonal 'breathing.'"

But everything is now in the research level. Scientists from NASA say that they cannot understand the whole thing without further testing.

So, we will have to wait more.

NASA's Mars Mission with Rover Curiosity

With its rover named Curiosity, Mars Science Laboratory mission is a part of NASA's Mars Exploration Program, a long-term effort of robotic exploration on the red planet of our Solar System. Curiosity was designed to assess whether Mars ever had an environment able to support small life forms called microbes. In other words, its mission is to determine the planet's "habitability."

Mars Science Laboratory will study Mars' habitability:
To find out, the rover carries the biggest, most advanced suite of instruments for scientific studies ever sent to the martian surface. The rover will analyze samples scooped from the soil and drilled from rocks. The record of the planet's climate and geology is essentially "written in the rocks and soil" - in their formation, structure, and chemical composition. The rover's on-board laboratory will study rocks, soils, and the local geologic setting in order to detect chemical building blocks of life (e.g., forms of carbon) on Mars and will assess what the martian environment was like in the past.

Mars Science Laboratory relies on innovative technologies:
Mars Science Laboratory will rely on new technological innovations, especially for landing. The spacecraft descended on a parachute and then, during the final seconds prior to landing, lowered the upright rover on a tether to the surface, much like a sky crane. Now on the surface, the rover will be able to roll over obstacles up to 75 centimeters (29 inches) high and travel up to 90 meters (295 feet) per hour. On average, the rover is expected to travel about 30 meters (98 feet) per hour, based on power levels, slippage, steepness of the terrain, visibility, and other variables.

The rover carries a radioisotope power system that generates electricity from the heat of plutonium's radioactive decay. This power source gives the mission an operating lifespan on Mars' surface of a full martian year (687 Earth days) or more, while also providing significantly greater mobility and operational flexibility, enhanced science payload capability, and exploration of a much larger range of latitudes and altitudes than was possible on previous missions to Mars.

Arriving at Mars at 10:32 p.m. PDT on Aug. 5, 2012 (1:32 a.m. EDT on Aug. 6, 2012), Mars Science Laboratory will serve as an entree to the next decade of Mars exploration. It represents a huge step in Mars surface science and exploration capability because it will:

• Demonstrate the ability to land a very large, heavy rover to the surface of Mars (which could be used for a future Mars Sample Return mission that would collect rocks and soils and send them back to Earth for laboratory analysis)
• Demonstrate the ability to land more precisely in a 20-kilometer (12.4-mile) landing circle
• Demonstrate long-range mobility on the surface of the red planet (5-20 kilometers or about 3 to 12 miles) for the collection of more diverse samples and studies.

Below are some images about the mission, mountain and rocks on mars, rover curiosity's own pictures, drilling pictures on the ground etc.
