3. Regional Rapid Transit System
The Prime Minister of India will inaugurate the first leg of the Regional Rapid Transit System (RRTS), India’s first mass rapid system dedicated to regional connectivity.

About the Regional Rapid Transit System:

  • It has semi high-speed rail connectivity at its core; the RRTS is an integrated mass transit network.
  • It aims to ensure “balanced and sustainable urban development” through better connectivity and access across the National Capital Region (NCR).
  • It is constructed by the National Capital Region Transport Corporation (NCRTC), which is a joint venture company of the Central government and the governments of Delhi, Haryana, Rajasthan, and Uttar Pradesh.
  • It is modelled on systems such as the RER in Paris, Regional-Express trains in Germany and Austria, as well as the SEPTA Regional Rail in the United States, among others.
  • These trains will travel significantly faster than metro trains. These will operate at a speed of 160 km/hour but are designed to be able to run at speeds up to 180 km/hour. 
  • Eight corridors will be developed under the project, of which three are being constructed under phase I: the 82-km Delhi-Ghaziabad-Meerut, the 164-km Delhi-Gurugram-SNB-Alwar, and the 103-km Delhi-Panipat corridors.
  • The significance of this system
    • When compared with metros, the RRTS network is faster. It will cater to commuters who want to travel relatively longer distances across the NCR in a short time.
    • Compared with the Indian Railways, though the RRTS train will cover relatively smaller distances, it will do so at higher frequency and provide relatively more comfort than the average railway coach.
4. Siena Galaxy Atlas (SGA)
Recently, astronomers have created a beautiful atlas of 400,000 galaxies in the cosmic neighbourhood of Milky Way and named it the Siena Galaxy Atlas.

About the Siena Galaxy Atlas:

  • It is a digital atlas that was created to get to know our universe better through several of the known galaxies.
  • It was created using data from three astronomical surveys collected between 2014 and 2017 at Cerro Tololo Inter-American Observatory (CTIO) and Kitt Peak National Observatory (KPNO). Together, these surveys are known as the DESI Legacy Surveys.
  • How is it different from other atlases?
    • It is dependent on state-of-the-art digital images captured by advanced technology, unlike previous atlases, which relied on antiquated equipment and photographic plates. 
    • As it is built on the images captured with highly sensitive instruments, it boasts the most accurate data.
    • It is also the first cosmic atlas to feature the light profiles of galaxies - a curve that describes how the brightness of the galaxy changes from its brightest point to its dimmest. 
  • Significance
    • Cosmic atlases help astronomers spot patterns that help categorise new discoveries, such as stars that suddenly flare and then disappear (thus called ‘transients’).
    • These atlases also allow astronomers to identify which objects are contenders for detailed follow-up studies. 
    • It helps in investigating everything from the births and evolutions of galaxies to the distribution of dark matter and propagation of gravitational waves through space.

10. Hang Gliders
The Directorate General of Civil Aviation (DGCA) recently issued a new set of regulations regarding the operation of powered hang gliders.

About Hang Gliders:

  • A hang glider is a type of aircraft that uses air currents to stay aloft.
  • Unlike other aircraft, hang gliders have no engine or propeller. 
  • Instead, they rely on the wind to keep them in the air.
  • How does it work?
    • Since a hang glider is unpowered, it can’t take off from low ground. It has to be launched from somewhere high, like a hill or mountain. 
    • Gravity is the main force on a hang glider. This is the weight of the pilot and the wing. 
    • The weight produces the thrust that keeps the aerofoil moving through the air. 
    • The aerofoil shape of the wing stops the hang glider from dropping like a stone. It produces lift.
    • The aerofoil forces the air flowing over the top of the wing to travel faster, thereby ‘stretching’ it to produce a low-pressure area.
    • Meanwhile, the downward and forward motion of the wing compresses the air flowing under the wing. 
    • The aerofoil is then drawn up into the area of low pressure, producing lift.
    • During the flight, the pilot controls the aircraft by the trapeze, both to change the direction and to vary the speed.
  • Powered Hang Gliders:
    • A powered hang glider is an aircraft that combines the features of a traditional hang glider with those of a powered aircraft.
    • They typically have a small engine attached to the frame, which allows the pilot to take off and stay in the air without having to rely on thermals or other weather conditions.
    • This can make them a good option for anyone who isn't experienced enough to take advantage of the winds to stay in the air.

DGCA Regulations on Powered Hang Gliders:

  • No individual is permitted to operate a powered hang glider without prior authorization from a DGCA-approved examiner or instructor. 
  • The qualified examiner or instructor must have a minimum of 50 hours of experience on powered hang gliders, including at least 10 hours on a dual machine.
  • Furthermore, the approved examiner or instructor is responsible for conducting thorough checks and authorising other individuals to fly.
  • Individuals must meet specific criteria before conducting test flights on a powered hang glider. This includes holding a valid Commercial Pilot Licence (CPL) with at least 25 hours of flying experience on a powered hang glider.
  • Alternatively, an individual must possess authorization along with 50 hours of flying experience on a powered hang glider, as stipulated in the revised regulations.
  • DGCA has mandated that any transaction involving the sale or transfer of a powered hang glider must be accompanied by a certificate issued by the DGCA. This certificate will only be granted following a thorough background check of prospective buyers conducted by the Ministry of Home Affairs (MHA).
  • No owner or operator is allowed to lease, rent, or lend a powered hang glider to any individual or entity.
  • The use of any remote sensing equipment, weapons, or photography and video recording devices on a powered hang glider is strictly prohibited without explicit permission from the MHA, unless it is deemed necessary for the safe operation of the aircraft or as specified by the relevant guidelines.
  • Security measures approved by the Bureau of Civil Aviation Security (BCAS) shall be adopted at the place of parking as well as at the place of operation before each flight by the owner or operator.
