Army signs deals for 130 tethered drones and 19 tank driving simulators

Tethered Drone

  • A tethered drone is an unmanned aerial vehicle tethered to the ground.
  • It consists of a base station on the ground and the drone, which is connected to the station through the tether (cable).
  • This tether provides power and data communication to the drone, allowing it to operate for extended periods without the limitations of a finite onboard battery.
  • The drone can be operated remotely to perform specific tasks.
  • Advantages:
    • Tethered UAVs are perfect for data capture and telemetry due to the reliability of tethered connections.
    • They dramatically reduce technical and human error crashes in flight.
    • They provide a secure line of communication between the ground station and the aircraft.
    • The physical connection to the ground makes tethered drones less vulnerable to interference or hacking compared to wireless drones.
    • It also does not require GPS navigation.
    • Many tethered drones have longer flight times compared to free-flying, battery-operated drones.
    • Due to the restricted movement of a tethered drone, the operator does not need piloting skills and can mainly focus on their tasks.

NASA to demonstrate laser communications from space station

ILLUMA-T

  • It is approximately the size of a standard refrigerator.
  • It will be secured to an external module on the International Space Station to conduct its demonstration with Laser Communications Relay Demonstration LCRD.
  • The ILLUMA-T, along with the LCRD (Launched in December 2021), will complete NASA’s first two-way, end-to-end laser relay system.
  • Once ILLUMA-T is on the space station, the terminal will send high-resolution data, including pictures and videos, to LCRD at a rate of 1.2 gigabits per second.
  • It is scheduled to launch on SpaceX’s 29th Commercial Resupply Services mission for NASA.
  • After its launch, ILLUMA-T will be installed on the station’s Japanese Experiment Module-Exposed Facility (JEM-EF).

Benefits

  • Laser communications enable missions to transmit more data in a single transmission.
  • More science and exploration data from space allow NASA to make more discoveries about our planet, microgravity, and the human spaceflight experience.
  • Laser communications systems provide numerous benefits to missions, including improved size, weight, and power requirements over comparable radio systems.
  • A smaller size increases the capacity of the spacecraft for other science instruments.
  • Less weight enables cost savings. Less power drain also means longer-lasting batteries.

Scientists Discover 7 “Cryptic” New Species of Walking Leaves

Walking Leaves

  • Walking Leaves, also called leaf insects, are insects that look very similar to leaves.
  • They are any of more than 50 species of flat, usually green insects (order Phasmida or Phasmatodea) that are known for their striking leaflike appearance.
  • They feed on plants and typically inhabit densely vegetated areas.
  • Distribution: Their natural range extends from islands in the Indian Ocean, across parts of mainland South Asia and Southeast Asia, to Papua New Guinea and Australia in the western Pacific.
  • Features:
    • They measure roughly 28 to 100 mm (1.1 to 3.9 inches) in body length.
    • Males tend to be smaller than females.
    • They are mostly brown or green, some slightly speckled or have serrated edges like nibbled leaves.
    • Movement: They sway and rock back and forth, imitating the motion of leaves in the breeze.
    • Female walking leaves cannot fly. Males can fly short distances thanks to their well-developed hind wings.
    • The arms and legs of walking leaves can regenerate.
    • Reproduction: These insects reproduce sexually, with females laying eggs. The eggs often resemble seeds or plant structures, adding to their camouflage.

World''s first prototype of the BS 6 Stage II ''Electrified Flex

Electrified Flex fuel vehicle

  • It is the World’s first BS-6 Stage-II Electrified Flex fuel vehicle.
  • An Electrified Flex Fuel Vehicle has both a Flexi Fuel engine and an electric powertrain.

How Do Flexible Fuel Cars Work Using Ethanol

  • Flexible fuel vehicles (FFVs) have an internal combustion engine and are capable of operating on gasoline and any blend of gasoline and ethanol up to 83%.
  • In flex fuels, the ratio of ethanol to petrol can be adjusted, but the most commonly used flex fuel uses 85 per cent ethanol and 15 per cent petrol.
  • Bio-ethanol contains less energy per litre than petrol, but the calorific value (energy contained in the fuel) of bio-ethanol will become on par with petrol with the use of advanced technology.
  • Since an FFV is capable of running on either petrol or ethanol, it will be the first of its kind 100 per cent dual fuel vehicle to be running on Indian roads.
  • Flex fuel engines are already popular in Brazil, the United States, the European Union and China, among many others.

Ethanol

  • Ethanol (also called ethyl alcohol or alcohol) is a biofuel with the chemical formula C2H5OH.
  • It is a by-product of the sugar production process and can be an excellent substitute for petrol as a fuel mix.
  • Ethanol is more affordable than petrol, as it can be produced domestically from crops, unlike crude oil, which needs to be imported.
  • It is a complex derivative of biomass left by agricultural feedstocks such as corn, sugarcane, hemp (bhang), potato, and rice, among many other things.
  • Using ethanol-blended fuel can help reduce our carbon footprint and create a cleaner, healthier environment for future generations.
  • Ethanol-blended petrol has significantly reduced emissions of harmful pollutants such as carbon monoxide, hydrocarbons, and nitrogen oxides.
  • India is the fifth largest manufacturer of ethanol, following the US, Brazil, the European Union and China.

Chandrayaan-3 probe shows 50°C difference between moon’s surface and 10 cm below

ChaSTE Probe

  • The Chandra’s Surface Thermophysical Experiment (ChaSTE) is a temperature probe.
  • It can be driven into the moon’s surface using a motor to a depth of up to 10 cm. It has 10 sensors.
  • It measured the temperature profile of the lunar topsoil around the South Pole to understand its thermal behaviour.
  • It was developed by the Space Physics Laboratory of ISRO’s Vikram Sarabhai Space Centre (VSSC), together with the Physical Research Laboratory (PRL), Ahmedabad.
  • Its findings reflect this variation between the moon’s surface, which is covered by a patina of loose rocks and dust called the lunar regolith and 10 cm under it.
  • Its data show that at the moon’s surface (where the lander is located, a point between the craters Manzinus C and Simpelius N), the temperature is 40-50 degrees But just under 80 mm under, it plunges to around -10 degrees C.
  • Significance of the findings
    • The temperature variation indicates that the moon’s topsoil is a powerful thermal insulator, in keeping with previous findings.
    • It adds credence to the idea that it can be used to build habitats for humans to shield them from frigid conditions and harmful radiation.
