Answer: Hydrogen
The cryogenic upper stage of GSLV uses Liquid Hydrogen (LH2) as fuel and Liquid Oxygen (LOX) as oxidizer. This combination provides high specific impulse, essential for lifting heavy payloads to geostationary orbits.
Answer: True
Nebulae are vast clouds of gas and dust in space. Some nebulae come from the gas and dust thrown out by the explosion of a dying star, while others are regions where new stars are beginning to form.

Answer: False
The Sun is not solid; it is a massive sphere of hot plasma (ionized gas). It generates energy through nuclear fusion in its core, converting hydrogen into helium.
Answer: Earth Observation and Mapping
Cartosat satellites are part of the Indian Remote Sensing (IRS) program, designed for high-resolution earth observation and cartographic applications.
Answer: Uranus
Uranus has an axial tilt of about 98 degrees, meaning it essentially rolls around the Sun on its side. This extreme tilt causes extreme seasonal variations.
Answer: Vikram Sarabhai
Dr. Vikram Sarabhai is widely regarded as the father of the Indian space program. He established the Physical Research Laboratory (PRL) and played a key role in the formation of ISRO.
Answer: False
Pluto is smaller than Earth's Moon. Pluto's diameter is about 2,377 km, while the Moon's diameter is about 3,475 km.
Answer: International Space Station (ISS)
