In statistics, multivariate adaptive regression splines (MARS) is a form of regression analysis introduced by Jerome H. Friedman in 1991. [1] It is a non-parametric regression technique and can be seen as an extension of linear models that automatically models nonlinearities and interactions between variables.
A first attempt at a Mars general circulation model was created by Leovy and Mintz who used an Earth model and adapted it to Martian conditions. This preliminary model had the capability to predict atmospheric condensation of carbon dioxide and the presence of transient baroclinic waves in the winter mod-latitudes. [ 4 ]
Born in The Hague, Mars Cramer was the son of biologist and Professor P. J. S. Cramer (1879–1952) [3] He received his PhD in Mathematics in 1961 at the University of Amsterdam with a thesis entitled "A Statistical Model of the Ownership of Major Consumer Durables with an Application to some Findings of the 1953 Oxford Savings Survey" under supervision of Pieter de Wolff [].
These lakes would be entirely encased in the moon's icy outer shell and distinct from a liquid ocean thought to exist farther down beneath the ice shell. Rather than an external impact, the authors propose a four-step model for producing the surface expressions (chaos terrain) and the shallow, covered lakes.
Colaprete et al. conducted simulations with the Mars General Circulation Model which show that the local climate around the Martian south pole may currently be in an unstable period. The simulated instability is rooted in the geography of the region, leading the authors to speculate that the sublimation of the polar ice is a local phenomenon ...

MARS-500 was intended to study the psychological, physiological, and technological challenges inherent to long-duration space flight. Among other hurdles to overcome, the experiment examined the physiological effects of long-term weightlessness, the effectiveness of resource management, and the effects of isolation in a hermetically sealed environment.
