Magnetic Field At Martian Surface Ten Times Stronger Than Expected

Fluctuations in field provide clues about upper atmosphere

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

First Direct Seismic Measurements Of Mars Reveal A Geologically Active Planet

Mars InSight

The first reports of seismic activity and ground vibrations on Mars are in. The red planet has a moderate level of seismic activity, intermediate between Earth and the Moon.

Staring into a Pit On Mars

This observation was meant to examine a pit identified in a Context Camera image to see if HiRISE could resolve any details inside.

The Mars 2020 Rover Is Being Prepared For Launch

The Mars 2020 rover undergoes processing inside the Payload Hazardous Servicing Facility at NASA's Kennedy Space Center in Florida on Feb. 14, 2020.

While InSight's seismometer has been patiently waiting for the next big marsquake to illuminate its interior and define its crust-mantle-core structure, two scientists, Takashi Yoshizaki (Tohoku University) and Bill McDonough (Tohoku University and University of Maryland, College Park) have built a new compositional model for Mars.

The Topography of Nilosyrtis Mensae

This colour-coded topographic image shows a region of Mars' surface named Nilosyrtis Mensae, based on data gathered by the Mars Express High Resolution Stereo Camera on 29 September 2019 during orbit 19908.

Mars 2020 Rover Arrives At Its Launch Site

The Mars 2020 rover is offloaded from a C-17 aircraft at the Launch and Landing Facility, formerly known as the Shuttle Landing Facility, at NASA's Kennedy Space Center on Feb. 12, 2020.

SwRI Models Hint At A Longer Timescale For Mars' Formation

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.

North Polar Changes over 6 Mars Years

MRO has been observing Mars for 6 Mars Years (MY), each of which lasts for 687 Earth days.

Mars Curiosity Loses Its Orientation

Knowing where our bodies are helps us move through the world.

Putting Mars 2020 Pieces Together

The Mars 2020 rover heat shield is mated to the back shell in the Payload Hazardous Servicing Facility at Kennedy Space Center in Florida on Jan. 10, 2020.

Stormy Activity At Mars' North Pole

This image shows part of the ice cap sitting at Mars' north pole, complete with bright swathes of ice, dark troughs and depressions, and signs of strong winds and stormy activity.

Mars 2020 Rover Completes Its First Drive

NASA's next Mars rover has passed its first driving test.

Newfound Martian Aurora Are Actually The Most Common

A type of Martian aurora first identified by NASA's MAVEN spacecraft in 2016 is actually the most common form of aurora occurring on the Red Planet, according to new results from the mission

Mars Express Views Phobos' Phases

ESA's Mars Express recently tracked Phobos as the moon passed in front of the spacecraft's camera, capturing detailed views of the small, irregularly shaped body at different angles and stages of the flyby

Two Rovers to Roll on Mars Again: Curiosity and Mars 2020

Curiosity won't be NASA's only active Mars rover for much longer.

Global Storms on Mars Launch Dust Towers Into the Sky

Dust storms are common on Mars. But every decade or so, something unpredictable happens: A series of runaway storms breaks out, covering the entire planet in a dusty haze

NASA Updates Mars 2020 Mission Environmental Review

As NASA continues preparations for the summer 2020 Florida launch of its Mars 2020 rover, including the recent completion of testing the spacecraft in Mars-like conditions, public safety remains a top priority.
