NASA spacecraft LADEE confirmed the presence of ______ gas in Moon's atmosphere.

Correct option is C

The correct answer is (c) Neon.
· NASA’s LADEE (Lunar Atmosphere and Dust Environment Explorer) spacecraft confirmed the presence of neon gas in the Moon's exosphere.
· This discovery showed that neon, often associated with fluorescent lighting on Earth, exists naturally in the thin atmosphere of the Moon, known as the exosphere.
· The presence of neon, along with other gases like helium and argon, was detected as part of NASA’s research on lunar surface and exosphere dynamics.
Information Booster:
· Krypton : A noble gas, rare in Earth's atmosphere, was not confirmed in the Moon's exosphere by LADEE.
· Xenon : Though used in ion thrusters for spacecraft, xenon was not detected in the Moon’s exosphere by LADEE.
· Radon : A radioactive noble gas, radon was not found by LADEE, but it can be emitted from the lunar soil due to natural radioactive decay.
· Exosphere Composition: The Moon’s exosphere is very tenuous and primarily consists of elements like helium, neon, and hydrogen, differing from Earth's atmosphere significantly in density and composition.
