A Bayesian approach to multivariate adaptive regression spline (MARS) fitting (Friedman, 1991) is proposed. This takes the form of a probability distribution over the space of possible MARS models which is explored using reversible jump Markov chain Monte Carlo methods (Green, 1995).

In this article the authors discuss how the adaptation of ideas from robotic planetary exploration would enable astronauts, as part of the U.S. National Aeronautics & Space Administration’s (NASA’s) human space program, to travel to asteroids and the planet Mars cheaply and quickly.

Fourth International Conference on Creating, Connecting and Collaborating through Computing (C5'06), 2006
Croquet on Mars is a very ambitious project whose goal is a massive collection of highly interactive material centered on the exploration and eventual colonization of Mars. Although the initial scope is mathematics, science, and engineering at the undergraduate level, the project is expected to expand rapidly to include middle and high school materials

Mars Climate Sounder Observation of Mars' 2018 Global Dust Storm
Geophysical Research Letters, 2020The largest of dust storms on Mars are global dust events (GDEs) that affect essentially every aspect of the Martian atmosphere but do not occur in every Mars year.

Hydrogen escape from Mars is driven by seasonal and dust storm transport of water
Science, 2020Dust storms cause Mars to lose water Mars was once a wet planet, but it has lost most of its water through reactions that produce hydrogen, which escapes from the upper atmosphere into space. Stone et al.

Journal of Paleolimnology, 1995
Observational evidence such as outflow channels and valley networks suggest that in the past there was flowing water on Mars. The images of fluvial features on Mars logically suggest that there must exist downstream locations in which the water pooled and the sediment load deposited (i.e. lakes). Sediments and morphological features associated with the

An international flotilla of spacecraft are to be sent to Mars over the next decade in an effort to understand the planet's geology and climate history, and to determine whether some form of life ever started there. At least two spacecraft will be sent at each launch opportunity, and at times up to four spacecraft may be operating simultaneously at the

ACM SIGGRAPH 2001 video review on Animation theater program, 2001
3.6 billion years ago, A microbe is blasted off its home planet from a meteor impact and embarks on a journey through the inner solar system. After spending time on other worlds, it decides home is best and tries to return - only to head in the wrong direction by mistake.
