Curious Mars

NASA has barely scratched the surface of Mars - literally. While past rovers have dug inches into the rusty soils of the Red Planet, NASA is testing out a drill that can go feet deep and operate autonomously with minimal human guidance.

The Composition of Mars

Comparing compositional models of the terrestrial planets provides insights into physicochemical processes that produced planet-scale similarities and differences.

Scientists at TU Dortmund University have generated high-accuracy 3D models of terrain within the landing ellipse of the ESA/Roscosmos ExoMars rover, Rosalind Franklin. The Digital Terrain Models (DTMs) have a resolution of about 25 cm per pixel and will help scientists to understand the geography and geological characteristics of the region and to plan the path of the rover around the site.

Scientists have long known that water was abundant on ancient Mars, but there has been no consensus on whether liquid water was common, or whether it was largely frozen in ice.

Using Gaussian Process regression to analyze the Martian surface methane Tunable Laser Spectrometer (TLS) data reported by Webster (2018), we find that the TLS data, taken as a whole, are not statistically consistent with seasonal variability.

Ancient hydrology is recorded by sedimentary rocks on Mars. The most voluminous sedimentary rocks that formed during Mars' Hesperian period are sulfate-rich rocks, explored by the Opportunity rover from 2004-2012 and soon to be investigated by the Curiosity rover at Gale crater.

This paper presents a case study of microbe transportation in the Mars-satellites system. We examined the spatial distribution of potential impact-transported microbes on the Martian moons using impact physics by following a companion study (Fujita et al.).

The processes behind the release and consumption of methane on Mars have been discussed since methane was measured for the first time for approx. 15 years ago.

A new international study led by Western University shows that Mars' first 'real chance' at developing life started very early, 4.48 billion years ago, when giant, life-inhibiting meteorites stopped striking the red planet.

This week, NASA's Curiosity Mars rover found a surprising result: the largest amount of methane ever measured during the mission -- about 21 parts per billion units by volume (ppbv).
