This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows evidence of wind deposition of fine sediment in the form of drifts in the lee of obstacles in the martian south polar region. The picture is located near 83.4°S, 8.1°W. [NASA/JPL/MSSS] [NASA/JPL/ASU] This daytim...
wouldn’t think that would make a difference but it does” (Weir 75) Explanation: Although Mark didn’t want to be in the Hab on Mars, it has become a second home for him in a way. This shows how Mark is adjusting to life on Mars but still wants to get out and is slowly going...

A distinctive feature of the Martian atmosphere is that the winter polar vortices exhibit annuli of high potential vorticity (PV) with a local minimum near the pole. These annuli are seen in observations, reanalyses, and free-running general circulation model simulations of Mars, but are not gene...
NASA Ingenuity Mars Helicopter 2,800 RPM Spin a Success, but Flight 14 Delayed to Post Conjunction It’s been an eventful several Martian days, or sols, since our last blog post, so we wanted to provide everyone with an update on where things stand onMars. In ourlast post, we ...
This before-and-after pair of images of the same patch of ground in front of NASA's Mars Rover Opportunity 13 days apart documents the arrival of a strange, bright rock at the scene. The rock, called "Pinnacle Island," is seen in the right image on Jan. 8, 2014. The image at left...
Unique Geological Conditions in Northern Russia According to Ana Morgado, a doctoral student and chemical engineer at the University of Cambridge, this phenomenon is extremely rare and specific to the Yamal and Gydan peninsulas in northern Russia. Cryopegs, which are ancient salty water pockets, exi...
More than1,200 sols (or Martian days) into the mission, Spirit analyzed a patch of dirtand found it was rich in silica, which provided some of the strongest evidenceyet that the Martian surface was once wet. Opportunity found salty areas in MerdianiPlanum that have garneredmany watery theo...
In contrast, theMars Exploration Rover Opportunity, which is also solar-powered, operates on a different timescale. It enters deep sleep each Martian night and wakes up each Martian morning, but the Martian day (sol) is much closer to an Earth day: 24 hours, 40 minutes long. This sleep ...
Seasonal D/H Data [9] The first impression from Figure 1a is that the atmospheric water vapor D/H is very large when the atmosphere's water vapor column, Pr, is small. The Mumma-Novak data are represented in Figure 1b as func- tions of latitude and Ls along with the Mars Global ...
