What is the name of the observatory to study Saturn's moon and comets by NASA 2018 campaign?

Correct option is C

The correct answer is (c) Sofia.
· SOFIA (Stratospheric Observatory for Infrared Astronomy) is an airborne observatory that was used by NASA to study Saturn’s moon and comets as part of its 2018 campaign.
· SOFIA is a joint project between NASA and the German Aerospace Center (DLR). It consists of a modified Boeing 747SP aircraft equipped with a 2.7-meter reflecting telescope.
· The observatory operates in the stratosphere, above most of the atmospheric water vapor, allowing it to capture high-resolution infrared images of celestial objects that are not possible from ground-based telescopes.
· SOFIA was particularly useful for studying the atmosphere of Saturn's moon Titan and analyzing the chemical composition of comets.
Information Booster:
· W.M. Keck Observatory: Located in Hawaii, it is a ground-based optical and infrared observatory known for its twin telescopes but not specifically used for studying Saturn's moons in the 2018 campaign.
· Pioneer 10: An American space probe launched in 1972, it was the first to travel through the asteroid belt and make direct observations of Jupiter, not used for observing Saturn's moons or comets in 2018.
· Aryabhata Space Observatory: This is not an existing observatory. Aryabhata was India’s first satellite launched in 1975, primarily for scientific experiments in X-ray astronomy and solar physics.
