The Indian National Committee for Space Research (INCOSPAR) was established in _______ under Dr. Vikram Sarabhai.
- 1957
- 1962
- 1969
- 1972
Answer: 1962
INCOSPAR was formed in 1962 within DAE, laying groundwork for ISRO's establishment in 1969; it initiated sounding rocket launches from Thumba.
Space elevators propose transporting payloads to orbit via tether anchored at the _______.
- North Pole
- Equator
- South Pole
- 45° latitude
Answer: Equator
Geostationary anchor point requires equatorial location; centrifugal force balances gravity along tether, enabling climber ascent without rockets.
The XPoSat mission carries POLIX payload to measure X-ray polarization in _______ energy band.
- Soft X-ray (0.5-2 keV)
- Medium X-ray (8-30 keV)
- Hard X-ray (30-100 keV)
- Gamma-ray (>100 keV)
Answer: Medium X-ray (8-30 keV)
POLIX (Polarimeter Instrument in X-rays) covers 8-30 keV, complementing AstroSat's CZTI and IXPE's soft band, studying accretion geometry.
The Vera C. Rubin Observatory's LSST will survey the entire visible sky every _______ nights.
- 1-2
- 3-4
- 7-10
- 30
Answer: 3-4
LSST's wide-field camera images 20,000 deg² every 3-4 nights, detecting transients, moving objects, and dark matter via weak lensing.
The SSLV-D3 mission successfully launched EOS-08 satellite in _______.
- 2022
- 2023
- 2024
- 2025
Answer: 2024
SSLV-D3 achieved success on Aug 16, 2024, deploying EOS-08 and SR-0 demosat, validating SSLV operational capability after prior failures.
Star trackers determine spacecraft attitude by matching observed star patterns against an onboard _______.
- Gyroscope database
- Star catalogue
- GPS ephemeris
- Sun sensor array
Answer: Star catalogue
Star trackers image star fields, compare centroids to stored catalogue entries, computing quaternion attitude with arcsecond accuracy.
The NETRA project establishes a network of radars and telescopes for _______ awareness.
- Weather
- Space situational
- Maritime domain
- Border surveillance
Answer: Space situational
NETRA (Network for Space Object Tracking and Analysis) monitors debris/threats to Indian satellites, integrating radar/optical sensors nationwide.
The Gaia DR3 catalogue released in 2022 contains astrometric data for over _______ stars.
- 100 million
- 1 billion
- 1.8 billion
- 10 billion
Answer: 1.8 billion
Gaia Data Release 3 provides positions, parallaxes, and motions for ~1.8 billion sources, revolutionizing galactic archaeology and stellar physics.
The Bhartiya Antariksh Station is planned to be operational by _______.
- 2028
- 2030
- 2035
- 2040
Answer: 2035
India aims to establish a modular space station by 2035, following Gaganyaan missions, supporting microgravity research and technology demonstration.
Reaction wheels control spacecraft orientation by conserving _______ momentum.
- Linear
- Angular
- Orbital
- Thermal
Answer: Angular
Accelerating/decelerating reaction wheels transfers angular momentum to/from spacecraft body, enabling precise pointing without propellant expenditure.
