Chemistry results showed the surface soil to be moderately alkaline, with a pH of 7.7 ±0.5. [ 53 ] [ 116 ] The overall level of salinity is modest. TEGA analysis of its first soil sample indicated the presence of bound water and CO 2 that were released during the final (highest-temperature, 1,000 °C) heating cycle.

The test was first published by Jean le Rond d'Alembert and is sometimes known as d'Alembert's ratio test or as the Cauchy ratio test.
Without the use of either trigonometry or a table of chords, Archimedes determines the Sun's apparent diameter by first describing the procedure and instrument used to make observations (a straight rod with pegs or grooves), [58] [59] applying correction factors to these measurements, and finally giving the result in the form of upper and lower ...
