Confirmation of ancient lake on Mars builds excitement for Perseverance rover's samples
on January 26, 2024 at 10:16 pm
Ground-penetrating radar on board NASA's Mars Perseverance rover has confirmed that the Jezero Crater, formed by an ancient meteor impact just north of the Martian equator, once harbored a vast lake and river delta. Over eons, sediment deposition and erosion within the crater shaped the geologic formations visible on the surface today. The discovery of lake sediments reinforces the hope that traces of life might be found in soil and rock samples collected by Perseverance.
Atmospheric pressure changes could be driving Mars' elusive methane pulses
on January 24, 2024 at 6:27 pm
New research shows that atmospheric pressure fluctuations that pull gases up from underground could be responsible for releasing subsurface methane into Mars' atmosphere; knowing when and where to look for methane can help the Curiosity rover search for signs of life.
Potential solvents identified for building on moon and Mars
on January 11, 2024 at 4:31 pm
Researchers have taken the first steps toward finding liquid solvents that may someday help extract critical building materials from lunar and Martian-rock dust, an important piece in making long-term space travel possible. Using machine learning and computational modeling, researchers have found about half a dozen good candidates for solvents that can extract materials on the moon and Mars usable in 3D printing. The powerful solvents, called ionic liquids, are salts that are in a liquid state.

Researchers have discovered the transformative potential of Martian nanomaterials, potentially opening the door to sustainable habitation on the red planet.
Glow in the visible range detected for the first time in the Martian night
on November 9, 2023 at 5:15 pm
Scientists have observed, for the first time in the visible range, a glow on the night side of the planet Mars. These new observations provide a better understanding of the dynamics of the upper atmosphere of the Red Planet and its variations throughout the year.
Scientists discover molten layer covering Martian core
on October 25, 2023 at 8:29 pm
NASA's InSight mission to Mars helped scientists map out Mars' internal structure, including the size and composition of its core, and provided general hints about its tumultuous formation. But findings from a new paper could lead to reanalysis of that data. An international team of researchers discovered the presence of a molten silicate layer overlying Mars' metallic core -- providing new insights into how Mars formed, evolved and became the barren planet it is today.
Curiosity rover finds new evidence of ancient Mars rivers, a key signal for life
on October 24, 2023 at 3:05 pm
New analysis of data from the Curiosity rover reveals that much of the craters on Mars today could have once been habitable rivers.
Source of largest ever Mars quake revealed
on October 17, 2023 at 4:34 pm
Scientists have announced the results of an unprecedented collaboration to search for the source of the largest ever seismic event recorded on Mars. The study rules out a meteorite impact, suggesting instead that the quake was the result of enormous tectonic forces within Mars' crust.
New Mars gravity analysis improves understanding of possible ancient ocean
on September 20, 2023 at 7:23 pm
The first use of a novel method of analyzing Mars' gravitational force supports the idea that the planet once had an extensive northern ocean. In doing so, the method defines the scope of what scientists refer to as the northern Martian paleo-ocean in more detail.
Possible seasonal climate patterns on early Mars
on August 9, 2023 at 8:47 pm
New observations of mud cracks made by the Curiosity Rover show that high-frequency, wet-dry cycling occurred in early Martian surface environments, indicating that the red planet may have once seen seasonal weather patterns or even flash floods.
Study examines Earth and Mars to determine how climate change affects the paths of rivers
on August 4, 2023 at 1:38 am
The study investigated why the paths of meandering rivers change over time and is a step toward understanding what the hydroclimate on Mars was like when there was still surface water.
In new space race, scientists propose geoarchaeology can aid in preserving space heritage
on July 21, 2023 at 3:32 pm
The material record that currently exists on the moon is rapidly becoming at risk of being destroyed if proper attention isn't paid during the new space era, scientists say. They propose a new scientific subfield: planetary geoarchaeology, the study of how cultural and natural processes on Earth's moon, on Mars and across the solar system may be altering, preserving or destroying the material record of space exploration.
New study reveals evidence of diverse organic material on Mars
on July 12, 2023 at 4:46 pm
Scientists gain vital insights into Mars' history and potential for supporting life.
Gauging the strength of ancient and active rivers beyond Earth
on July 10, 2023 at 10:04 pm
A new technique allows scientists to see how intensely rivers used to flow on Mars, and how they currently flow on Titan. The method uses satellite observations to estimate the rate at which rivers move fluid and sediment downstream.
Gullies on Mars could have been formed by recent periods of liquid meltwater, study suggests
on June 29, 2023 at 11:32 pm
A study offers new insights into how water from melting ice could have played a recent role in the formation of ravine-like channels that cut down the sides of impact craters on Mars.
Using photosynthesis for Martian occupation -- while making space travel more sustainable
on June 9, 2023 at 4:56 pm
Researchers are working on sustainable technology to harvest solar power in space -- which could supplement life support systems on the Moon and Mars.
New findings indicate gene-edited rice might survive in Martian soil
on April 27, 2023 at 1:05 am
New research suggests future Martian botanists may be able to grow gene-edited rice on Mars.
Scientists detect seismic waves traveling through Martian core
on April 24, 2023 at 8:28 pm
New NASA InSight research reveals that Mars has a liquid core rich in sulfur and oxygen, leading to new clues about how terrestrial planets form, evolve and potentially sustain life.

Remains of a modern glacier found near Mars' equator implies water ice possibly present at low latitudes on Mars even today
on March 15, 2023 at 5:24 pm
Scientists revealed the discovery of a relict glacier near Mars' equator. Located in Eastern Noctis Labyrinthus at coordinates 7° 33' S, 93° 14' W, this finding is significant as it implies the presence of surface water ice on Mars in recent times, even near the equator. This discovery raises the possibility that ice may still exist at shallow depths in the area, which could have significant implications for future human exploration.
