Question No. 1

Consider the following statements regarding space-based internet networks:
1.Mega-constellations can be deployed across both Low Earth Orbit (LEO) and Geostationary Orbit (GEO) architectures to attain global commercial coverage.
2.Space-based internet completely bypasses terrestrial infrastructure, removing any operational requirement for fixed ground transceiver stations or ISPs.
3.High latency remains a primary technical advantage of utilizing Low Earth Orbit (LEO) satellite constellations compared to standard optical-fiber broadband networks.

B1 and 2 only

C2 and 3 only

D1, 2 and 3

Question No. 2

Consider the following statements regarding the new observation facilities sanctioned in Ladakh:
1.The National Large Solar Telescope (NLST) is a 2-metre aperture system designed for Merak to observe solar magnetism and dynamics, making it India’s third active ground-based solar observatory.
2.The National Large Optical Telescope (NLOT) features a 13.7-metre segmented-mirror setup at Hanle, engineered to study exoplanets using optical-infrared wavelengths.
3.Upon completion, both NLST and NLOT will be operated entirely under the direct financial control of the Kodaikanal Solar Observatory.
How many of the statements given above are correct?

AOnly one

BOnly two

CAll three

DNone

Question No. 3

Consider the following statements regarding the Moonshot Project launched by IISc and the Pratiksha Trust:
1.The project aims to develop bidirectional brain co-processors that can decode neural recordings, analyze cognitive states, and re-encode signals back via neural stimulation.
2.The technology acts as a standard one-way conventional Brain-Computer Interface (BCI) aimed exclusively at capturing motor cortex outputs.
Which of the statements given above is/are correct?

A1 only

B2 only

CBoth 1 and 2

DNeither 1 nor 2

Question No. 4

Consider the following statements:
1.ISRO first demonstrated its foundational structural capability to safely recover an orbiting craft using the Space Capsule Recovery Experiment (SRE) in 2007.
2.The planned winged Orbital Re-entry Vehicle (ORV) must be manually steered via a ground pilot crew throughout its descent to land safely on a standard runway.
Which of the statements given above is/are correct?

A1 only

B2 only

CBoth 1 and 2

DNeither 1 nor 2

Question No. 5

Consider the following statements regarding Mission MITRA:

AIt is an astronomical observation program utilizing the Astrosat platform to trace electromagnetic stress anomalies across distant star systems.

BIt represents a behavioral and physiological assessment program conducted at Leh, Ladakh, to evaluate Gaganyaan crew capabilities under extreme stress profiles like hypoxia and isolation.

CThe mission is carried out as a defense venture controlled exclusively by the Defense Research and Development Organisation (DRDO).

DIts primary design goal is to train international space tourists for low Earth orbit civilian spaceflights.

Question No. 6

Consider the following statements:
1.Mons Mouton is a massive, flat-topped lunar mountain structure located near the Moon’s South Pole, which has been identified as a target site for the Chandrayaan-4 mission.
2.The primary objective of the Chandrayaan-4 mission is to establish a permanent human outpost on Mons Mouton by the end of 2026.

DNeither 1 nor 2

Question No. 7

Consider the following statements regarding Solid Fuel Ducted Ramjet (SFDR) propulsion technology:
1.The propulsion structure merges the benefits of standard solid-fuel rocket boosters with an air-breathing ramjet engine system.
2.By utilizing atmospheric oxygen as an oxidizer for sustained cruise phases, the system significantly reduces the required structural weight of onboard oxidizers.
3.Because it requires a constant, highly pressurized internal turbopump array, the SFDR system cannot be used for compact long-range air-to-air missiles.
Which of the statements given above are correct?

A1 and 2 only

B2 and 3 only

C1 and 3 only

D1, 2 and 3
