European Space Agency (ESA) will  launch world’s first wooden satellite called WISA Woodsat in Earth’s orbit by the end of 2021.

WISA Woodsat

will be launched to test the applicability of wooden materials such as plywood in spacecraft structures. Mission will expose wooden materials to extreme space conditions like heat, cold, vacuum and radiation. Wooden satellite will be launched to space by end of 2021 with a Rocket Lab Electron rocket. It will be launched from Mahia Peninsula launch complex in New Zealand. Satellite has been designed and built in Finland.

Features of satellite

Satellite will orbit at around 500-600 km altitude in polar Sun-synchronous orbit. It is a10x10x10 cm nano satellite which was built up using standardised boxes and surface panels of plywood, which is usually found in hardware store and are used to make furniture. Wood have been placed in a thermal vacuum chamber to keep dry when it is in space. Thin layer of aluminium oxide has been applied to it to minimise vapour coming from wood and to protect it from erosive effects of atomic oxygen. The non-wooden external parts of satellite are corner aluminium rails which will be used for its deployment into space and a metal selfie stick.

While speaking at UN Trade Forum 2021, Union Minister Piyush Goyal has said, India’s per-capita carbon dioxide emission is lowest amongst big economies.

UN Trade Forum was established as a space for dialogue on how trade can be harnessed to get a prosperous, inclusive and sustainable world.

Sustainable Development Goals (SDG)

SDG are collection of 17 interlinked global goals which are designed to be a blueprint of achieving a better and more sustainable future for all. SDGs were set up in 2015 by United Nations General Assembly. They are intended to be achieved by 2030. SDGs are included in UN Resolution called “2030 Agenda” these goals were developed in Post-2015 Development Agenda as future global development framework and replaced the Millennium Development Goals which ended in 2015.

Researchers from Raman Research Institute (RRI), Space Applications Centre, Shiv Nadar University in Gautam Buddha Nagar and Université Rennes & Université Paris-Saclay of France have modulated light source and demodulated them at observer’s end to achieve sharper images.

Key Points


Researchers have long attempted to use physics of scattering and computer algorithms to process resulting data and improve quality of images. But computer algorithms require processing of large volumes of data increasing storage and processing time.

About the technique

Researchers selected ten red LED lights as source of light. They modulated this source of light by varying current flowing through LEDs at a rate of about 15 cycles per second. A camera was installed at a distance of 150 metres from the LEDs, which captured image and transmitted it to desktop computer. Then, computer algorithms used knowledge of modulation frequency to extract characteristics of the source. This process is dubbed as ‘demodulation’.

Significance of technique

This technique is cost effective as it requires only a few LEDs and an ordinary desktop computer. It can improve landing techniques of aeroplanes by providing pilot with a good view of beacons across the runway. It is better than relying only on reflected radio waves. This method can also reveal obstacles in path which are otherwise hidden by fog in rail, sea, and road transportation. It can help in identifying lighthouse beacons.

Bihar exported the first commercial consignment of GI certified Jardalu mangoes from Bhagalpur to the United Kingdom. Jardalu mangoes from Bhagalpur district were given GI certification in 2018.


Agricultural and Processed Food Products Export Development Authority, (APEDA) in collaboration with Bihar government, Indian High Commission & Invest India, exported Jardalu mangoes. Mangoes were packed and treated at APEDA packhouse in Lucknow.

How APEDA has been contributing towards export?

Mango Production in India

Mango are referred to as king of fruits. They are also referred to as Kalpavriksha (wish granting tree) in ancient scriptures. Uttar Pradesh, Bihar, Telangana, Andhra Pradesh, Karnataka have a major share in total production of Mango.

The Great Indian Bustards are making it slow to manoeuvre while flying. They have poor frontal vision and a habit of scanning earth while flying over flat grasslands across western borders of India. As a result, they often collide with power lines.

What is the issue?

Wide-open regions are home to Indian Bustard. These regions are also an ideal location for wind and solar projects. As a result, Indian Bustard are coming in way of renewable energy sources. Efforts to save bustard could set back India’s climate goals, which depend heavily on availability of such wasteland.

WII survey

As per Wildlife institute of India (WII), 80 kilometres of power lines across Thar desert region Rajasthan had led to death of four bustard deaths during a single year because of high-transmission wires. Birds died because of impact of collision or electrocution.

SC’s order

In a bid to protect great Indian bustard from flying into power lines, of 20 gigawatts of awarded solar & wind projects, Supreme Court had asked the companies to install these powers lines underground. But this directive would cost an extra expense of $4 billion.

Great Indian bustards

In Old French, Great Indian Bustards means “slow bird”. They are heaviest flying creatures on earth. They are 1 meter tall with a wing span of about 2 meters. They weigh about 18 kilograms. They are found on Indian subcontinent. As per an estimate their number has reduced from 250 in 2011 to 150 in 2018. Thus, they have been listed in “critically endangered” species by birdlife international and are protected under Wildlife Protection Act 1972 of India.

Chinese spacecraft, Shenzhou-19, will blast off from Gobi Desert on a Long March rocket soon. Spacecraft will ferry three men to an orbiting space module where they will stay for three-month. This will be the first time China will send humans into space since 2016.


Shenzhou-12 means Divine Vessel. It will be third out of 11 missions that China needs to complete China’s space station by 2022. Out of 11, four will be missions with people on board. Thus, a total of 12 Chinese astronauts will go into space.

About Shenzhou-12 Mission

This human spaceflight will also carry into space the hopes of some in Earth’s most populous nation. Shenzhou-12 crew will live on the Tianhe which is a cylinder having 16.6 metres length and 4.2 metres diameter. Crew will stay in space for three months, breaking its own record of 30 days stay in 2016 mission.


Chinese astronauts have relatively low international profile currently because United States law banned NASA from any connection with China. Thus, Chinese astronauts have not been to International Space Station for more-than-two-decade. Thus, China is launching several space missions with the aim of becoming a major spacefaring power by 2030. Recently, in May 2021 it became second country to put a rover on Mars.

Reserve Bank of India on has expanded the scope of Bharat Bill Payment System (BBPS) which will be effective from August 31, 2021.

Government will implement mandatory hallmarking of gold jewellery and artefacts from June 15, 2021.


What is Gold Hallmarking?

Gold hallmarking is a purity certification for precious metal. Presently, gold hallmarking is voluntary. Currently, 40 % of the gold jewellery is being hallmarked.

Why Hallmarking is mandatory now?

Government has launched mandatory hallmarking of gold with the aim of ensuring consumers do not get cheated while buying ornaments. Mandatory hallmarking will protect public against lower caratage and it will ensure consumers get purity as marked on jewellery. Thus, from 15 June 2021, jewellers will only be allowed to sell gold jewellery of 14, 18 and 22 carats. Registration process has been made online and automatic.

Hallmarking scheme

BIS is already running the hallmarking scheme for gold jewellery since April 2000. Government had announced mandatory hallmarking of gold jewellery & artefacts in November 2019.

Current scenario

According to World Gold Council, India has about 4 lakh jewellers. Out of them only 35,879 have been BIS certified. There has been 25 per cent increase in assaying and hallmarking centres in last five years. With the existing capacity, 14 crore articles can be hallmarked in a year.
