1. It is a Beyond Visual Range (BVR) class of air-to-air missile. 2. The range of the Astra Mk-1 missile is around 110 km. Which of the statements given above is/are correct?
With reference to the concentration of fluoride in groundwater, consider the following statements:
National Quantum Mission:
The National Quantum Mission (NQM) was approved by the Union Cabinet in 2023 at a total cost of Rs.6003.65 crore from 2023-24 to 2030-31.
It aims to seed, nurture and scale up scientific and industrial & D and create a vibrant; innovative ecosystem in Quantum Technology (QT).
Smart Cities Mission:
The Smart Cities Mission has been extended for the third time till March 31, 2025.
The objective of SCM is to promote cities that provide core infrastructure and give a decent quality of life to its citizens, a clean and sustainable environment through the application of 'Smart' solutions.
The term "FLiRT and "LB.1" were recently in the news. They correspond to:
The Saffir-Simpson Scale is used to measure intensity of:
The visit to Russia is a signal of New Delhi's commitment to its partnership with Moscow, as well as an emphasis on this foreign policy objective.
India's ties with Russia date back seven decades. As India has expanded its partnerships in a multipolar world, the India-Russia relationship has stalled in certain sectors and weakened in others.
Defence is by far the strongest component of the strategic alliance, with nuclear and space cooperation also playing a vital role.
India and Russia have inked deals to deliver S-400 Triumf mobile surface-to-air missile systems, MiG-29 fighter planes, and Kamov helicopters, as well as licence manufacturing of T-90 tanks, Su-30MKI fighters, AK-203 assault weapons, and BrahMos supersonic cruise missiles.
Admiral Gorshkov was the former Soviet and Russian vessel that served as one of the Indian Navy's two aircraft carriers, the INS Vikramaditya.
Consider the following:
1. Kamov helicopters 2. C-17 Globemaster 3. Su-30MKI fighters 4. MH-60R Seahawks 5. T-90 tanks Which of the defence equipment given above is part of the India-Russia agreement?
The term "Apophis" was recently in the news. It refers to:
India's first solar mission, the Aditya-L1 spacecraft completed its first halo orbit around the Sun-Earth L1 point.
The space agency said its station-keeping manoeuvre ensured its seamless transition into the second halo orbit.
The Aditya-Ll mission, which is an Indian solar observatory at Lagrangian point L1, was launched on September 2, 2023 using PSLV-C57 and was inserted in its targeted halo orbit on January 6, 2024.
According to ISRO, Aditya-Ll spacecraft in the halo orbit takes 178 days to complete a revolution around the L1 point.
During its travel in the halo orbit, Aditya-L1 spacecraft will be subjected to various perturbing forces that will cause it to depart from the targeted orbit.
The major science objectives of Aditya-L1 mission are:
(i) Study of Solar upper atmospheric (chromosphere and corona) dynamics.
(ii) Study of chromospheric and coronal heating, physics of the partially ionized plasma, initiation of the coronal mass ejections, and flares
(iii) Observe the in-situ particle and plasma environment providing data for the study of particle dynamics from the Sun.
(iv) Physics of solar corona and its heating mechanism.
(v) Diagnostics of the coronal and coronal loops plasma: Temperature, velocity and density.
(vi) Development, dynamics and origin of CMEs.
(vii) Identify the sequence of processes that occur at multiple layers (chromosphere, base and extended corona) which eventually leads to solar eruptive events.
(viii) Magnetic field topology and magnetic field measurements in the solar corona.
(ix) Drivers for space weather (origin, composition and dynamics of solar wind.
