Device Could Help Detect Signs of Extraterrestrial Life

Although Earth is uniquely situated in the solar system to support creatures that call it home, different forms of life could have once existed, or might still exist, on other planets. But finding ...

Study Shows Difficulty in Finding Evidence of Life on Mars

While scientists are eager to study the red planet's soils for signs of life, researchers must ponder a considerable new challenge: Acidic fluids - which once flowed on the Martian surface - may have ...

Sustained Planetwide Storms May Have Filled Lakes, Rivers on Ancient Mars

A new study is helping scientists piece together the ancient climate of Mars by revealing how much rainfall and snowmelt filled its lake beds and river valleys 3.5 billion to 4 billion years ...

The Most Sensitive Instrument in the Search for Life Beyond Earth

Researchers have developed the highly sensitive ORIGIN instrument, which can provide proof of the smallest amounts of traces of life, for future space missions. The instrument may be used on missions ...

Origin of Martian Moon Phobos

New images of the Martian moon Phobos give scientists insight into the physical properties of the moon and its ...

NASA's Curiosity Rover Finds Clues to Chilly Ancient Mars Buried in Rocks

By studying the chemical elements on Mars today -- including carbon and oxygen -- scientists can work backwards to piece together the history of a planet that once had the conditions necessary to ...

Mystery of Lava-Like Flows on Mars Solved

The mystery of some lava-like flows on Mars has been solved by scientists who say they are caused not by lava but by mud. There are tens of thousands of these landforms on the Martian surface, often ...

What's Mars Made Of?

Earth-based experiments on iron-sulfur alloys thought to comprise the core of Mars reveal details about the planet's seismic properties for the first time. This information will be compared to ...

Scientists Have Modeled Mars Climate to Understand Habitability

Scientists have modeled the atmosphere of Mars to help determine that salty pockets of water present on the Red Planet are likely not habitable by life as we know it on Earth. The team helped allay ...

New Timeline for Ancient Magnetic Field on Mars

Mars had a global magnetic field much earlier -- and much later -- than previously known. Analysis of new satellite data found clear evidence of a magnetic field coming from a lava flow that formed ...

4-Billion-Year-Old Nitrogen-Containing Organic Molecules Discovered in Martian Meteorites

Scientists exploring Mars and analysing Martian meteorite samples have found organic compounds essential for life: nitrogen-bearing organics in a 4-billion-year-old Martian meteorite. With a new ...

Promising Signs for Perseverance Rover in Its Quest for Past Martian Life

New research indicates river delta deposits within Mars' Jezero crater -- the destination of NASA' Perseverance rover on the Red Planet -- formed over time scales that promoted habitability ...

Engineers' 'Nanocardboard' Flyers Could Serve as Martian Atmospheric Probes

Engineers are suggesting a new way to explore the sky: tiny aircraft that weigh about as much as a fruit fly and have no moving parts. These flyers are plates of 'nanocardboard,' which ...

A Martian Mash Up: Meteorites Tell Story of Mars' Water History

Researchers probed Martian meteorites to reconstruct Mars' chaotic history. Their findings suggest that Mars might not have had a global magma ...

Organic Molecules Discovered by Curiosity Rover Consistent With Early Life on Mars

Organic compounds called thiophenes are found on Earth in coal, crude oil and oddly enough, in white truffles, the mushroom beloved by epicureans and wild pigs. Thiophenes were also recently ...

Ancient Meteorite Site on Earth Could Reveal New Clues About Mars' Past

Scientists have devised new analytical tools to break down the enigmatic history of Mars' atmosphere -- and whether life was once possible there. It could help astrobiologists understand the ...

A Year of Surprising Science from NASA's InSight Mars Mission

A new understanding of Mars is beginning to emerge, thanks to the first year of NASA's InSight lander mission. Findings described in a set of six papers reveal a planet alive with quakes, dust ...

Magnetic Field at Martian Surface Ten Times Stronger Than Expected

New data gleaned from the magnetic sensor aboard NASA's InSight spacecraft is offering an unprecedented close-up of magnetic fields on ...

Journey to the Center of Mars

Scientists have built a new compositional model for Mars. They used rocks from Mars and measurements from orbiting satellites to predict the depth to its core-mantle boundary, some 1,800 km beneath ...

Mars: Simulations of Early Impacts Produce a Mixed Mars Mantle

The early solar system was a chaotic place, with evidence indicating that Mars was likely struck by planetesimals, small protoplanets up to 1,200 miles in diameter, early in its history. Scientists ...

Mars' Water Was Mineral-Rich and Salty

Presently, many scientists believe Mars is the best candidate in the search for life beyond Earth because it is relatively nearby and there is good evidence that liquid water flowed on Mars' ...

Evidence of Strong Early Magnetic Field Around Earth

New research provides evidence that the magnetic field that first formed around Earth was even stronger than scientists previously believed. The research will help scientists draw conclusions about ...

Mars: Water Could Disappear Faster Than Expected

The small red planet is losing water more quickly than what theory as well as past observations would suggest. An international research team has just revealed that water vapor is accumulating in ...

Scientists Map a Planet's Global Wind Patterns for the First Time, and It's Not Earth

A new article documents the global wind patterns on any planet for the first time. Remote repogramming of the MAVEN spacecraft and its NGIMS instrument enabled the data collection. The results reveal ...
