Atomic oxygen detected in the atmosphere of Mars
Q. Recently scientists discovered which of the following in atmosphere of Mars?- Published on 09 May 16a. Atomic Oxygen
b. Oxygen
c. Ozone
d. All of the above
ANSWER: Atomic Oxygen
- Scientists have detected atomic oxygen in the atmosphere of Mars for the first time since the last observation 40 years ago.
- These atoms were found in the upper layers of the Martian atmosphere known as the mesosphere. Atomic oxygen affects how other gases escape Mars and therefore has a significant impact on the planet’s atmosphere.
- An instrument on-board the Stratospheric Observatory for Infrared Astronomy (SOFIA) detected only about half the amount of oxygen expected, which may be due to variations in the Martian atmosphere.
- To observe the far-infrared wavelengths needed to detect atomic oxygen, researchers must be above the majority of Earth’s atmosphere and use highly sensitive instruments, in this case a spectrometer. SOFIA provides both capabilities.
