Topic in Syllabus: Security Issues
India on 12 June conducted a successful first test flight of the indigenously developed Hypersonic Technology Demonstrator Vehicle (HSTDV) from a base off the Odisha coast.
It has a range of uses, including missiles of the future, and energy-efficient, low cost and reusable satellite-launch vehicle.
What is HSTDV?
- Hypersonic Technology Demonstrator Vehicle in short it is known as HSTDV. It is an unmanned scramjet demonstration aircraft.
- It is designed to cruise at Mach 6 speed with scramjet engine up to an altitude of 32.5 kilometres in 20 seconds.
• HSTDV is dual-use technology thus with a scramjet engine, HSTDV can cruise at Mach 6 speed and can have multiple civilian applications.
• It can be used for launching satellites at low cost and can also be available for long-range cruise missiles of future.
• The design for airframe attachment with the engine was completed in the year 2004.
About Scram-Jet technology
In scram-jet technology, fuel combustion takes place in a chamber in missile at supersonic speeds while in a ram jet system, the system collects air it needs from atmosphere during flight at subsonic speeds and propellants burn in combustion chamber.
The only other countries that possess this technology are the US, Russia and China.
Hypersonic Technology Demonstrator Vehicle is
- an unmanned scramjet demonstration aircraft
- allows supersonic combustion
- can cruise up to six times the speed of the sound
Which of the above statement is/are Correct?
a). 1 and 2 only
b). 1 and 3 only
c). All of the above
Topic in Syllabus: Indian Geography
About Cyclone Vayu:
‘Vayu’ was the second most intense cyclonic storm to have formed near the Indian coast after Cyclone Fani, which left a trail of destruction in Odisha on the eastern coast in early May. Fani was the longest-lasting cyclone over the Bay of Bengal, hovering for over 11 days.
- Cyclones are sustained by very strong low-pressure areas at their core. Winds in surrounding areas are forced to rush towards these low-pressure areas.
- Similar low-pressure areas, when they develop near or over land, are instrumental in pulling the monsoon winds over the country as well.
- But right now, the low-pressure area at the center of the cyclone is far more powerful than any local system that can pull the monsoon winds moving northeast.
- Arabian Sea cyclones are also relatively weak compared to those emerging in the Bay of Bengal.
- Gujarat coastline, where most of the cyclones emerging in the Arabian Sea are headed, is not very densely populated, ensures that the damage potential of the cyclones on the western coast is comparatively low.
Bay of Bengal More Prone to Cyclones?
- Temperature difference: The low-pressure system of cyclone need a continuous supply of heat energy and as the Bay of Bengal is warmer than the Arabian sea, it is able to provide the heat energy needed to sustain the low-pressure system.
- Sea surface temperatures and humidity: both directly correlate with chances of cyclone formation.
- The Bay of Bengal receives higher rainfall and constant inflow of fresh waterfrom the Ganga and Brahmaputra rivers.
- This means that the Bay’s surface water keeps getting refreshed, making it impossible for the warm water to mix with the cooler water below, making it ideal for depression.
- Absence of large landmass between the Pacific and the Bay, allows cyclonic winds to easily move into the Bay of Bengal.
- Cyclones from Pacific ocean: low-pressure system originating from the Pacific ocean also travel towards the left to the Bay of Bengal.
Match the colours with different Cyclonic Alerts
- Yellow: Be Updated
- Orange: Be prepared
- Red: Take action
- Green: No warning

Topic in Syllabus: Science & Technology
Chandrayaan-2 is India’s second lunar exploration mission after Chandrayaan-1, developed by the Indian Space Research Organisation.
Ritu Kridhal and M Vanitha are leading as project and mission directors respectively for Chandrayaan-2 mission.
- Quantify the water available on the moon’s surface.
- Map its topography, to explore chemicals and minerals such as magnesium, iron, and Helium.
- Study topmost part of the lunar atmosphere.
- If successful, India will be the fourth country (After Russia, China, and the USA) to land a rover on the moon.
- India will be the first country to land on the southern pole of the moon.
- This would give ISRO opportunity to name that site on the moon.
- Indigenous mission: 13 instruments from India, one instrument from US space agency, NASA.
- Future Space Exploration: mission will also expand the country’s footprint in space as moon is the perfect test-bed for proving technologies required for future space exploration.
Significant Components of Chandrayaan-2
Chandrayaan-2 is ISRO’s upcoming Lander and Rover mission to Moon.-consists of an Orbiter, Lander and Rover.
- The Orbiter will 100 km away from the moon, which will observe lunar surface and relay communication between Earth and the Lander.
- The orbiter is equipped with different kinds of camera to take create high-resolution three-dimensional maps of the surface, would remain in orbit for a year.
Vikram Lander– .
- It is the first time that ISRO is attempting to soft-land a module in extra-terrestrial space.
- The main challenge is in controlling its speed as it approaches the surface.
- Once the Lander and the Rover, enter the Moon’s gravity, they would be in a state of free fall.
- To enable a smooth landing, the speed of the Lander just ahead of touchdown should be 1 m/s (3.6 km/h) or less.
- The Lander will mainly study the moon’s atmosphere and look out for seismic activity.
- The 6-wheeled, AI Solar powered rover was designed, developed and build indigenously by ISRO.
- The rover will be landed in be landed closer to the Moon’s equator to receive more sun light.
- Its primary objective will be to study the composition of the surface near the lunar landing site, and determine its abundance of various elements.
- Both the Lander and Rover are designed to work for only 14 days (1 lunar day).
Complexities involved in a moon landing
- Trajectory accuracy: Ensuring trajectory accuracy while navigating 3.844 lakh km has its own challenges.
- Communication hurdle: Owing to the large distance from Earth, radio signals, which need to be picked up, would be weak.
- Lunar dust: Firing engines close to the lunar surface results in the backward flow of gases and dust, causing hindrance to deployment mechanism and damaging sensors.
- Extreme temperatures: A lunar day or night lasts 14 earth days, resulting in extreme surface temperature.
- Trans-lunar injection, capture:Series of engine burns to get close to the moon, intersection of probe and moon must be predicted in advance with accuracy.
- Orbiting: The lumpy lunar gravity influences the orbit of the spacecraft.
Which of the following statements is/are correct about Chandrayaan-2?
- It will includes a lunar orbiter, a lander and a lunar rover.
- The lander is developed with help of NASA.

India’s is ranked 141 among 163 countries on the Global Peace Index 2019.(136 in 2018)
The GPI is a report produced by the Institute for Economics and Peace (IEP) and developed in consultation with an international panel of peace experts from peace institutes and think tanks with data collected and collated by the Economist Intelligence Unit.
The GPI measures ongoing domestic and international conflict, safety and security in society, and the degree of militarisation in 163 countries and territories by taking into account 23 indicators.
- The index ranked Iceland as the most peaceful country in the world,a position it has held since 2008.Other countries at the top of the Global Peace Index(GPI) are New Zealand, Austria, Portugal, and Denmark.
- Afghanistan has been ranked as the least peaceful country in the world replacing Syria which is now the second least peaceful.
- The report has also said that India along with the Philippines, Japan, Bangladesh, Myanmar, China, Indonesia, Vietnam and Pakistan are the nine countries with the highest risk of multiple climate hazards.
- The report also says that the US, China, Saudi Arabia, Russia and India are the top five countries with the largest total military expenditure.
Global Peace Index(GPI):
- The GPI was founded by Steve Killelea, an Australian technology entrepreneur and philanthropist.
- It is released by Australian think tank Institute for Economics & Peace.
- It ranks countries according to their level of peacefulness based on three thematic domains:
- The level of societal safety and security.
- The extent of ongoing domestic and international conflict.
- The degree of militarisation.
- Possible effects of climate change on peace is newly included in this research.
According to Global Peace Index 2019, Which country managed to retain its position as the most peaceful country in the world?
