The 'LUPEX' mission is a joint lunar exploration project between ISRO and which agency?
Correct Answer: D. JAXA
LUPEX (Lunar Polar Exploration) is a collaboration between ISRO and JAXA (Japan). The mission aims to explore the Moon's South Pole for water resources. It involves a Japanese launch vehicle and rover, and an Indian lander.
Which ISRO center is responsible for the tracking and command of satellites?
Correct Answer: C. ISTRAC
The ISRO Telemetry, Tracking and Command Network (ISTRAC) is headquartered in Bengaluru. It provides ground support for all of ISRO's satellite and launch vehicle missions. ISTRAC has a network of ground stations across India and around the world.
The 'S200' boosters used in the LVM3 rocket use which type of propellant?
Correct Answer: C. Solid
S200 is one of the world's largest solid rocket boosters and provides the initial thrust for LVM3. Solid propellants are easy to store and provide high thrust, though they cannot be turned off once ignited. Two such boosters are attached to the core stage of the rocket.
Which mission was ISRO's first dedicated mission for deep space astronomy?
Correct Answer: D. AstroSat
AstroSat, launched in 2015, is a multi-wavelength space observatory. It can simultaneously observe the universe in Ultraviolet, Optical, and X-ray bands. It has provided valuable data on star formation and high-energy processes in the cosmos.
What is the primary purpose of the 'RISAT' series of satellites?
Correct Answer: D. Radar imaging for all-weather monitoring
Radar Imaging Satellites (RISAT) can see through clouds and provide imagery even at night. This makes them extremely useful for agriculture, forestry, and disaster management during monsoons. They are also vital for border monitoring and national security.
Which Indian rocket was the first to use a cryogenic upper stage developed indigenously?
Correct Answer: A. GSLV Mk-II
The GSLV Mk-II successfully used the Indian-made CE-7.5 cryogenic engine in 2014. Before this, India relied on cryogenic engines supplied by Russia. Developing this technology was a major breakthrough for the Indian space program.
The 'HysIS' satellite launched by ISRO is designed for which type of imaging?
Correct Answer: D. Hyperspectral
Hyperspectral Imaging Satellite (HysIS) can observe Earth in a large number of contiguous narrow spectral bands. This allows for detailed identification of objects and materials on the surface. It is used for applications in agriculture, geology, and environmental monitoring.
Which ISRO center is responsible for processing and distributing satellite data for Earth observation?
Correct Answer: D. NRSC
The National Remote Sensing Centre (NRSC) is located in Hyderabad. it acts as the primary hub for receiving and analyzing data from Indian remote sensing satellites. This data is used for mapping and managing natural resources.
What is the name of the project aimed at protecting Indian space assets from space debris?
Correct Answer: A. Project NETRA
Project NETRA (Network for space object Tracking and Analysis) is an early warning system in space. It monitors space debris and other hazards that could collide with Indian satellites. This initiative is crucial for ensuring the safety and sustainability of India's space operations.
Which ISRO mission is planned to explore the planet Venus?
Correct Answer: A. Shukrayaan-1
Shukrayaan-1 is a proposed orbiter mission to study the atmosphere and surface of Venus. It will carry high-resolution synthetic aperture radar and other scientific instruments. The mission aims to understand why Venus evolved so differently from Earth.
