MAVEN Identifies Links to Atmospheric Loss on Mars

New findings from NASA’s Mars Atmosphere and Volatile Evolution (MAVEN) mission reveal a new process by which the solar wind can penetrate deep into a planetary atmosphere, leading to atmospheric loss. Early discoveries by NASA’s newest Mars orbiter are starting to reveal key features about the loss of the planet’s atmosphere to space over time. […]

Signs of Ancient Mars Lakes and Quakes Seen in New Map

A new geological map based on NASA images shows signs of ancient lakes and quakes on Mars. This animation simulates a flyover of a portion of a Martian canyon detailed in a geological map produced by the U.S. Geological Survey and based on observations by the HiRISE camera on NASA’s Mars Reconnaissance Orbiter. The landforms […]

NASA Prepares to Send Humans to Mars

NASA scientists are developing the capabilities needed to send humans to an asteroid by 2025 and to Mars by the 2030s. In the not-too-distant future, astronauts destined to be the first people to walk on Mars will leave Earth aboard an Orion spacecraft. Carried aloft by the tremendous power of a Space Launch System rocket, […]

Textures in Rock Provide Evidence about Wet Environmental Conditions on Ancient Mars

This close-up image of a Martian rock has provided scientists with evidence about wet environmental conditions in the ancient past on Mars. This close-up view of a target rock called “Last Chance” was acquired by the microscopic imager on the arm of NASA’s Mars Exploration Rover Opportunity on March 3, 2004, during the 39th Martian […]

Research Shows Warmth and Flowing Water on Early Mars

New research from Brown University and Israel’s Weizmann Institute of Science shows that warmth and water flow on ancient Mars were probably episodic, related to brief periods of volcanic activity that spewed tons of greenhouse-inducing sulfur dioxide gas into the atmosphere. Providence, Rhode Island (Brown University) — Ample evidence of ancient rivers, streams, and lakes […]

NASA Spacecraft Reveal Comet Flyby Effects on Martian Atmosphere

Data from several spacecraft have revealed that debris from Comet Siding Spring added a temporary and very strong layer of ions to the ionosphere of Mars, allowing scientists to make a direct connection from the input of debris from a specific meteor shower to the formation of this kind of transient layer in response. Two […]

Curiosity Provides First Confirmation of a Mineral Mapped from Orbit

A sample of powdered rock extracted by the Curiosity rover’s drill from the “Confidence Hills” target has provided NASA scientists with the first confirmation of a mineral mapped from orbit. “This connects us with the mineral identifications from orbit, which can now help guide our investigations as we climb the slope and test hypotheses derived […]

Hubble Views Comet Siding Spring Near Mars

This new composite image of comet Siding Spring was captured by NASA’s Hubble Space Telescope as Sliding Spring made its never-before-seen close passage of Mars. Siding Spring, officially designated Comet C/2013 A1, made its closest approach to Mars at 2:28 p.m. EDT on October 19, at a distance of approximately 87,000 miles. That is about […]

Assessing the Technical Feasibility of the Proposed Mars One Mission

A new independent assessment of the Mars One Mission from MIT engineers reveals that the project may have to take a step back, at least to reconsider the mission’s technical feasibility. In 2012, the “Mars One” project, led by a Dutch nonprofit, announced plans to establish the first human colony on the Red Planet by […]
