[3] [5] [2] The atmosphere of Mars is much thinner and colder than Earth's having a max density 20g/m 3 (about 2% of Earth’s value) with a temperature generally below zero down to -60 Celsius. The average surface pressure is about 610 pascals (0.088 psi) which is 0.6% of the Earth's value. [2]
~2.0 cm/s Jaseja et al. [28] 1964: The frequencies of two He–Ne masers, mounted on a rotating table, were compared. Unlike Cedarholm et al., the masers were placed perpendicular to each other. ~30 m/s Shamir and Fox [29] 1969: Both arms of the interferometer were contained in a transparent solid . The light source was a Helium–neon laser.
