Iran unveils upgraded hypersonic missile as Khamenei touts Israel ‘failure’
Fattah 2
- Fattah, which means conqueror in Farsi, is a hypersonic ballistic missile.
- It was developed by Iran. It is a new version of its first domestically made hypersonic ballistic missile named ‘Fattah’.
- Features:
- It is equipped with a hypersonic glide vehicle (HGV) warhead that can manoeuvre and glide at hypersonic speed.
- It uses a liquid-fuel rocket propellant.
- The precision-guided two-stage missile can hit targets within a range of 1500 kilometres with a velocity of Mach 15 (fifteen times the speed of sound i.e., 18522 km/hr).
- It can make quick turns to avoid defence systems.
- It is equipped with a warhead that has a spherical engine running on solid fuel and movable nozzles that allow it to change course when outside the atmosphere to accurately help it evade air-defence systems.
Hypersonic Missile
- A hypersonic missile is a weapon system that flies at least at the speed of Mac 5, i.e., five times the speed of sound and is manoeuvrable.
- These missiles are extremely fast and far harder for surface-to-air missile defence systems to target.

Can the Global Biodiversity Framework Fund make a difference?
Experts said that the world’s new biodiversity framework fund lacks any real financial commitment to meet conservation targets.
Global Biodiversity Framework Fund:
- It was created to ramp up investment in nature restoration and renewal.
- It has been designed to mobilise and accelerate investment in the conservation and sustainability of wild species and ecosystems, whose health is under threat from wildfires, flooding, extreme weather, and human activity, including urban sprawl.
- The fund was established at the 7th Assembly of the Global Environment Facility in Vancouver, Canada.
- It will help countries achieve the 23 targets set under the Kunming-Montreal Global Biodiversity Framework (KMGBF).
- The framework was adopted at the 15th Conference of the Parties (COP15) to the UN Convention on Biological Diversity last December.
- It will be managed by the Global Environment Facility (GEF) and raise funds through private, philanthropic, and government investments.
- This is a departure from GEF, which relied on just 40 donors for finance.
- It will also have access to funds earmarked for biodiversity conservation under GEF.
- The facility has a cumulative budget of $5.25 billion for 2022-26, of which 36 percent is earmarked for biodiversity.
- The remaining budget is for projects on climate change, pollution, land and ocean health.
- The GBF Fund Council will be open to representation by the following members,
- 16 Members from developing countries
- 14 Members from developed countries
- 2 members from the countries of central and eastern Europe and the former Soviet Union.
- Decisions of the GBF Fund Council are to be taken by consensus, along the lines of the GEF Instrument.
Hero stones, inscriptions found in Sathya Sai district
Nolamba Dynasty
- They were one of the significant political powers in South India.
- The Nolambas ruled from the **8th to the 12th centuries C.**E. over an area traditionally called Nolambavadi, which extended over south-east Karnataka and parts of Tamil Nadu and Andhra Pradesh.
- They ruled first as feudatories to Pallavas, Chalukyas of Badami, Gangas, and Rashtrakutas, and later to Chalukyas of Kalyani.
- Nolambas commonly referred to themselves as Nolamba Pallava in several inscriptions.
- Their earlier capital was Chitradurga, which they later shifted to Hemavati in modern Andhra Pradesh. Hemavathi was the capital between the 8th and 10th centuries AD.
- Origin:
- Mangala Nomabathi Raja (735–785 A.D.) was considered the founder of the Nolamba dynasty.
- Inscriptional evidence suggests that they came into existence as governors when the Pallavas and Chalukyas were supreme powers.
- With the seizure of Badami by the Pallava ruler Mamalla Narasimhavarman I, the Chalukyas ceded the territories that were ruled by the Banas and Vaidumbas to the Pallavas.
- The Banas and Vaidumbas thus became feudatories of the Pallavas.
- The Nolambas, who were perhaps related to the Pallava family, governed the region adjacent to these lands of Pallava feudatories, namely the Banas and Vaidumbas.
- Sometime later, during the rule of Vikramaditya I, the Chalukyas regained their lost territories. The Banas and Vaidumbas thus had to change their political relationship back to the Chalukyas.
- The Pallava chiefs, who were adjacent to the Banas and Vaidumbas, were defeated by the Chalukyas, who soon came under their protection. These Pallava chiefs soon came into existence under the name of “Nolambas”.
- Decline: Nolambas were overrun by the Ganga king Marasimha, who boasts of having destroyed the Nolamba family and had the title Nolambakulantaka.
- Three grand temple complexes that are attributed to this dynasty''s glory are the Kalleshwara Temple in Aralaguppe, the Bhoganandishwara Temple in Nandi, and the Ramalingeshwara Temple in Avani.
- The Nolambas were Shaivites, and the temples they built were dedicated to Lord Shiva.
Hammer Candlestick: What It Is and How Investors Use It
Hammer Candlesticks in Trading
- It is one of the most popular candlestick patterns traders use to gauge the probability of outcomes when looking at price movement.
- A hammer is a price pattern in candlestick charting that occurs when a security trades significantly lower than its opening but rallies within the period to close near the opening price.
- This pattern forms a hammer-shaped candlestick, in which the lower shadow is at least twice the size of the real body.
- The body of the candlestick represents the difference between the opening and closing prices, while the shadow shows the high and low prices for the period.
- The hammer candlestick occurs when sellers enter the market during a price decline. By the time the market closes, buyers absorb selling pressure and push the market price near the opening price.
- The close can be above or below the opening price, although the close should be near the open for the real body of the candlestick to remain small.
- Analysts view it as a potential bullish trend reversal indicator, mainly appearing at the end of a downtrend.
- It could be used as a leading intraday indicator to signal a change in bullish/bearish momentum.
