ISRO Receives Satellites for SPADEX Docking Mission

Image
  The Indian Space Research Organisation (ISRO) has recently acquired two 400kg satellites for an important mission called SPADEX, or Space Docking Experiment. This mission aims to demonstrate the ability of two satellites to dock in space, marking a key step for future space missions. SPADEX Mission Overview SPADEX involves launching two satellites into slightly different orbits using a single rocket. Once in space, these satellites will travel at speeds of approximately 28,000 km/h. They will align and perform a ‘space handshake’ to dock together, forming one orbiting unit. This docking capability is crucial for future missions, including  Chandrayaan-4  and the proposed Indian Space Station. Significance of Docking Docking technology is essential for various space operations. For instance, when astronauts travel to a space station, their spacecraft must dock precisely with the station. This ensures safe transfer of crew and cargo. SPADEX will validate the autonomous re...

Cabinet Approves ₹2,642 Crore Ganga Rail-Cum-Road Bridge

Image
Project Overview The new rail-cum-road bridge will help make transport faster and more efficient in the Varanasi-Chandauli area in Uttar Pradesh. This area is important for both passenger and freight traffic (goods transport), as it’s seeing more demand due to tourism and industry growth. Why is Varanasi Railway Station Important? Varanasi Railway Station is a major hub in India’s railway system. It connects many important areas and handles a lot of passenger traffic as well as goods like coal, cement, and food grains. It’s also key for pilgrims and tourists visiting the city, which boosts the local economy. Current Challenges The railway route between Varanasi and Pandit Deen Dayal Upadhyaya Junction is very crowded, especially with the high volume of goods being transported. This congestion is causing delays, and the current infrastructure cannot keep up with the growing demand. How will the Project Help? To reduce this congestion, the project will include: A new rail-cum-road bridge...

Sun Reaches Solar Maximum, Increasing Activity and Impacts

Image
The Sun has entered a period called solar maximum, part of its current solar cycle, which has led to an increase in sunspots and solar activity. This phase could affect everyday life on Earth, according to Jamie Favors, head of NASA’s Space Weather Programme. What is Solar Maximum? Solar maximum is a phase in the Sun’s 11-year cycle where the Sun’s magnetic activity increases significantly. During this time, the Sun shows more sunspots, solar flares, and coronal mass ejections (CMEs). The Sun’s magnetic poles may even flip, leading to this surge in activity. Characteristics of Solar Maximum During solar maximum:Sunspots are dark spots on the Sun’s surface that are cooler than the surrounding areas. The Sun produces more solar flares (explosions of energy) and CMEs (massive ejections of solar material). These events make the solar system more active and unpredictable. Impact on Earth The increased solar activity can trigger solar storms, which send charged particles toward Earth. These ...

Record Solar Power Capacity Reached Globally in 2023

Image
In 2023, the world added 347 gigawatts (GW) of solar energy, marking a 74% increase from the previous year. This rapid growth was driven by the falling costs of solar panels and supportive government policies, as noted in a report by IRENA and the International Labour Organization (ILO). Key Contributors China played the biggest role in this solar energy boom, contributing 63% of the new capacity, which amounted to 216.9 GW. Other leading countries, like the United States, Germany, Brazil, India, Spain, Italy, the Netherlands, Japan, and Australia, added a total of 83.4 GW. Europe alone increased its solar energy capacity by over 54 GW, while the US added about 25 GW. Employment Growth The surge in solar energy also led to a sharp rise in jobs. Global employment in the solar photovoltaic (PV) sector grew to 7.1 million jobs in 2023, up from 4.9 million in 2022. Most of these jobs were in China, which accounted for 4.6 million positions. Europe had around 757,500 solar jobs, mainly in ...

Southern Africa Culls Elephants Amid Severe Drought Crisis

Image
Southern Africa is experiencing its worst drought in over a century, causing serious food shortages. Countries like Zimbabwe and Namibia have started wildlife-culling programs to address the growing food insecurity caused by this environmental crisis. What is Causing the Drought? The drought in southern Africa is mainly due to the El Niño weather pattern, which has caused much less rain than usual in the region. Climate change is making this problem worse by making droughts like this more frequent and severe. Government Responses In response to the hunger caused by the drought, Zimbabwe has decided to cull (or kill) 200 elephants. The meat from these animals will be given to poor communities. Similarly, Namibia has allowed the culling of 723 animals, including elephants, hippos, and zebras, from its national parks. This is meant to help provide food during the crisis. Conflict Between Wildlife and Humans As the drought worsens, both humans and animals are struggling to find food and w...

Butterfly Migration Thrives In Tamil Nadu’s Western Ghats

Image
Tamil Nadu recently saw a massive migration of butterflies from the Danainae sub-family, specifically the species called ‘tigers and crows.’ These butterflies moved from the Eastern Ghats (a mountain range in India) toward the Western Ghats. This migration in 2023 was much larger than in the previous year. Butterfly Sub-family The Danainae sub-family includes well-known butterflies like:Blue Tiger Dark Blue Tiger Double-branded Crow Common Crow These butterflies typically follow a two-part migration pattern. First, they fly toward the hills before the northeast monsoon (which brings rain), and then they return to the plains after the southwest monsoon (another rainy season). Migration Pattern The Nature and Butterfly Society (TNBS) has been tracking this butterfly migration since 2013. Every year, they see a large number of butterflies emerging in the last week of September. The butterflies usually start migrating early in the morning and continue until the evening. On peak days, hundr...

Oldest Eyeliner Discovered in Turkey’s Ancient Prehistoric City

Archaeologists have recently found the oldest known kohl stick, a type of ancient eyeliner, at an archaeological site called Yeşilova Höyük in Turkey. This discovery shows that people have been using makeup for more than 8,000 years. The Discovery The kohl stick is made from a green serpentine stone and has traces of black paint on its tip. It is more than 8,200 years old, making it the earliest evidence we have of people using cosmetics. Zafer Derin, the lead archaeologist, explained that kohl has been used in many different cultures throughout history. Kohl was commonly used in places like Egypt, the Levant (eastern Mediterranean), and Anatolia (modern-day Turkey). It was not just for looking beautiful but also had medicinal purposes. The presence of this kohl stick suggests that even 8,200 years ago, women in the Aegean region of Yeşilova cared about enhancing their appearance. Physical Details of the Kohl Stick The kohl stick is about 10 cm long and 1 cm thick. It is finely shape...
