The 'LUPEX' mission is a joint lunar exploration project between ISRO and which agency?
Correct Answer: D. JAXA
• **JAXA** = LUPEX is a joint lunar exploration project between ISRO and JAXA (Japan). • **Moon's South Pole** — The mission aims to explore this region for water resources. • 💡 Wrong-option analysis: NASA: Not the partner for LUPEX with ISRO; Roscosmos: Not the partner for LUPEX with ISRO; ESA: Not the partner for LUPEX with ISRO.
Which ISRO center is responsible for the tracking and command of satellites?
Correct Answer: C. ISTRAC
• **ISTRAC** = This ISRO center is responsible for the tracking and command of satellites. • **Bengaluru** — ISTRAC's headquarters are located here, providing central ground support. • 💡 Wrong-option analysis: VSSC: Primarily responsible for rocket and launch vehicle development; SAC: Deals with space applications, remote sensing, and communication payloads; NRSC: Primarily processes and distributes Earth observation satellite data.
The 'S200' boosters used in the LVM3 rocket use which type of propellant?
Correct Answer: C. Solid
• **Solid** = S200 boosters use this type of propellant, providing initial thrust for the LVM3 rocket. • **Two** — This is the number of S200 solid rocket boosters attached to the LVM3's core stage. • 💡 Wrong-option analysis: Liquid: Used in the LVM3's core stage, not the S200 boosters; Cryogenic: Used in the LVM3's upper stage, not the S200 boosters; Gas: Not a primary propellant type for large rocket boosters.
Which mission was ISRO's first dedicated mission for deep space astronomy?
Correct Answer: D. AstroSat
• **AstroSat** = This was ISRO's first dedicated mission for deep space astronomy. • **2015** — AstroSat, a multi-wavelength space observatory, was launched in this year. • 💡 Wrong-option analysis: Mars Orbiter: A planetary mission to Mars, not primarily deep space astronomy; Aditya-L1: A mission to study the Sun, not deep space astronomy; Chandrayaan-1: A lunar orbiter mission, not primarily deep space astronomy.
What is the primary purpose of the 'RISAT' series of satellites?
Correct Answer: D. Radar imaging for all-weather monitoring
• **Radar imaging for all-weather monitoring** = This is the primary purpose of the 'RISAT' series of satellites. • **Clouds and night** — RISAT satellites can provide imagery even through these conditions. • 💡 Wrong-option analysis: Direct-to-home TV: Handled by communication satellites like INSAT/GSAT series; Oceanography: Primarily served by Oceansat series satellites; Tele-education: A communication application, not the main purpose of radar imaging satellites.
Which Indian rocket was the first to use a cryogenic upper stage developed indigenously?
Correct Answer: A. GSLV Mk-II
• **GSLV Mk-II** = This Indian rocket was the first to use an indigenously developed cryogenic upper stage. • **2014** — The GSLV Mk-II successfully used the Indian-made CE-7.5 cryogenic engine in this year. • 💡 Wrong-option analysis: GSLV Mk-I: Used Russian-supplied cryogenic engines initially; PSLV: Does not use a cryogenic upper stage; SLV-3: An early, smaller launch vehicle that did not have a cryogenic stage.
The 'HysIS' satellite launched by ISRO is designed for which type of imaging?
Correct Answer: D. Hyperspectral
• **Hyperspectral** = The 'HysIS' satellite is designed for this type of imaging. • **Large number of contiguous narrow spectral bands** — HysIS observes Earth using these bands for detailed identification. • 💡 Wrong-option analysis: Thermal: Relates to heat sensing, distinct from hyperspectral; Panchromatic: Refers to a single broad band, not multiple narrow ones; Infrared: A specific part of the electromagnetic spectrum, not the overall imaging type for HysIS.
Which ISRO center is responsible for processing and distributing satellite data for Earth observation?
Correct Answer: D. NRSC
• **NRSC** = This ISRO center is responsible for processing and distributing satellite data for Earth observation. • **Hyderabad** — The National Remote Sensing Centre (NRSC) is located in this city. • 💡 Wrong-option analysis: VSSC: Primarily for rocket and launch vehicle development; ISTRAC: Responsible for satellite tracking and command, not data processing/distribution; SAC: Focuses on space applications and payload development, not primary data distribution.
What is the name of the project aimed at protecting Indian space assets from space debris?
Correct Answer: A. Project NETRA
• **Project NETRA** = This project is aimed at protecting Indian space assets from space debris. • **Early warning system** — Project NETRA functions as this in space to monitor debris and hazards. • 💡 Wrong-option analysis: Project AKASH: Not related to space debris protection; Project SURAKSHA: A generic term for protection, not the specific name for this initiative; Project AMBAR: Not the known name for ISRO's space debris tracking project.
Which ISRO mission is planned to explore the planet Venus?
Correct Answer: A. Shukrayaan-1
• **Shukrayaan-1** = This ISRO mission is planned to explore the planet Venus. • **Atmosphere and surface of Venus** — Shukrayaan-1 is proposed to study these aspects of the planet. • 💡 Wrong-option analysis: Varun-1: Not a known ISRO planetary mission name; Arun-1: Not a known ISRO planetary mission name; Mangalyaan-2: A proposed mission to Mars, not Venus.
