Presently it is being used during shunting of trains at Jabalpur, Murwara and other stations on trial basis.
This dual mode locomotive has also received the Best Innovation Award from the Railway Board.
With this new locomotive, Railways will save 1000 litres of diesel per day and it will be used more after clearing all the trials.
About the Nav Doot
This e-engine can haul 18 coaches at a speed of 30 kmph.
It has 84 batteries and currently has a towing capacity of 400 tonnes.
It has been developed by the Electricity Department of New Katni Junction.
After clearing all the tests, it will be used more widely for purposes like carrying goods, coal, oil tankers etc. to other stations.
2. Country's first '5G testbed' launched
Tags: Science and Technology National News
Prime Minister Narendra Modi inaugurated the country's first 5G testbed, which will enable industry players and startups to test and validate their products locally.
This testbed has been set up at a cost of Rs 220 crore.
This 5G testbed has been developed as a multi-institution collaborative project by 8 institutes led by IIT Madras.
Due to no 5G testbed till now, startups and industry players had to go abroad to test and validate their products.
This testbed will create a supportive ecosystem for the Indian industry and startups to help them validate their products, prototypes, solutions and algorithms in 5G and next-gen technologies.
Other institutes involved in the project are IIT Delhi, IIT Hyderabad, IIT Bombay, IIT Kanpur, IISc Bangalore, Society for Applied Microwave Electronics Engineering and Research (SAMEER) and Centre of Excellence in Wireless Technology (CEWiT).

The Indian Space Research Organisation (ISRO) successfully completed the static test of the 'Human-rated' solid rocket carrier (HS200) for the Gaganyaan program at the Satish Dhawan Space Centre (SDSC) in Sriharikota, Andhra Pradesh.
The HS200 satellite launch vehicle is a 'human-rated' version of the GSLV Mk III S200 rocket carrier, popularly known as LVM-3.
The 'human-rated' version is the process of certification of a spacecraft or launch vehicle to show that the vehicle is capable of carrying humans safely into space.
The design and development of the HS200 carrier was completed at VSSC, Thiruvananthapuram and the propellant casting was completed at SDSC, Sriharikota.
The S200 motor is the first stage of the LVM-3 launch vehicle, intended to launch a 4,000 kg class satellite into geosynchronous transfer orbit.
After the success of this test, ISRO has moved one more step towards the Gaganyaan program.
Gaganyaan mission of india
Gaganyaan is a mission of the Indian Space Research Organisation (ISRO).
Under this mission, three space missions will be sent into orbit, out of these three missions, 2 will be unmanned, while one will be a manned mission.
In the first phase, Gaganyaan's unmanned mission will be G-1. After this a robot named Vyommitra will be sent at the end of 2022.
Gaganyaan mission with crew will be launched for the first time in 2023.
The human space flight programme, called the Orbital Module, will have three Indian astronauts, including a woman.
The three-stage GSLV Mk III will be used for the launch of Gaganyaan, which is capable of launching heavy satellites. GSLV Mk III is also called Launch Vehicle Mark-3.
With the launch of Gaganyaan mission, India will join the club of US, China and Russia.

5. Scientists discover almost 35 million years old rare snake fossil from Ladakh Himalaya
Tags: Popular Science and Technology
Scientists have discovered for the first time the fossil of a Madtsoidae snake from molasses deposits in the Ladakh Himalayas.
This indicates its prevalence in the subcontinent for a longer period of time than previously thought.
Madtsoiidae is an extinct group of medium-sized to gigantic snakes.
It firstly appeared during the Cretaceous and mostly distributed in the Gondwanan landmasses.
Although, their Cenozoic record is extremely scarce.
The occurrence of Madtsoiidae from the Oligocene of Ladakh indicates their continuity at least to the end of the Paleogene (geologic period and system that spans 43 million years from the end of the Cretaceous Period 66 million years ago).
The research was published in the Journal of Vertebrate Palaeontology.
The newly discovered fossil specimen is housed in the repository of Wadia Institute, an autonomous institute of Department of Science and Technology.

Tags: National Science and Technology
After the Moon and Mars mission, India is now going to participate in the journey of Venus along with America and other countries.
The purpose of this campaign is to gather information about the atmosphere of Venus.
The project report of 'Shukrayan-1', the name given to the Venus mission of ISRO, is ready and the budget has also been fixed for this.
The cost of the Venus mission is likely to be between ₹500 crore to ₹1,000 crore, depending on the level of equipment.
About Shukrayaan-I Mission
Shukrayaan will be India's first orbiter mission to Venus.
It will be similar to Moon and Mars missions.
The mission aims to study the surface of the hottest planet in our solar system.
It also aims to unravel the mysteries under the Sulphuric Acid clouds enveloping on Venus.
Its atmosphere is highly toxic and corrosive.
Studying the structure, composition, and dynamics of the atmosphere.
ISRO is planning to launch orbital manoeuvres in December 2024 when Earth and Venus will converge.
About Venus
Venus is the second planet from the Sun and Earth’s closest planetary neighbour. Mercury is closer to the Sun.
Venus is the hottest planet in our solar system.
The surface temperature on Venus is about 900 °F (475 °C), high enough to melt lead.
Its dense atmosphere is filled with the greenhouse gas carbon dioxide, and contains clouds of sulfuric acid.
Venus is sometimes called Earth's twin because it is similar in size and composition, but the planet differs greatly in other respects.
