Oblateness of the atmosphere of Mars
Nature, 1976ON April 8, 1976 Mars occulted the bright star ɛ Geminorum (magnitude 3.2). Predictions1 were issued well in advance since such occurrences are very rare: indeed, it is estimated that Mars occults a star as bright as this about once in 500 yr. Accurate observations of the duration of the occultation were made from four sites on the Earth and these are ...

The Atmosphere and Climate of Mars
2017Humanity has long been fascinated by the planet Mars. Was its climate ever conducive to life? What is the atmosphere like today and why did it change so dramatically over time? Eleven spacecraft have successfully flown to Mars since the Viking mission of the 1970s and early 1980s.
