NASA’s LADEE finds neon in lunar atmosphere
Q. NASA’s LADEE spacecraft has found which gas in the lunar atmosphere for the first time?- Published on 14 Sep 15a. Hydrogen
b. Helium
c. Neon
d. None of the above
ANSWER: Neon
The Lunar Atmosphere and Dust Environment Explorer NASA spacecraft has found neon which is a gas commonly used in electric signs in the thin lunar atmosphere. Its existence on the moon has been speculated since the Apollo Mission, and scientists have now solid proof of the existence of neon in relatively abundant qualities in the lunar atmosphere. The neon is not sufficient to make the moon glow as the latter’s atmosphere is around 100 trillion times less dense at sea level than earth’s atmosphere. A dense atmosphere results in gravity and it is rare in our solar system.
