Curiosity experienced a computer reset on its Side-A computer on Wednesday, March 6, 2019 (Sol 2,339), that triggered the rover's safe mode. […]

NASA declared the record-setting rover's mission complete on Feb. 13, 2019, but the final image from the rover has just been processed. […]

The lander's second instrument is on the ground. But its ‘mole’ — a burrowing probe — has a long way to go. […]

NASA's Opportunity Mars rover mission is complete after 15 years on Mars. Opportunity's record-breaking exploration laid the groundwork for future missions to the Red Planet. […]

Opportunity's mission is complete. Here are highlights from its time on Mars. […]

Three years ago, on March 14 2016, the Bernese Mars camera CaSSIS started its journey to Mars with the 'ExoMars Trace Gas Orbiter' spacecraft. The camera system has been observing Mars from its primary science orbit since April 2018 and provides high-resolution, color images of the surface. On 2 March 2019, CaSSIS also delivered its first image of InSight, NASA's lander on Mars. […]

An international team of researchers is tackling one of the biggest problems of space travel to Mars: what happens when we get there? […]

A new article defines specific scientific objectives for a Mars Sample Return campaign, to describe the critical measurements that would need to be done on returned samples to address the objectives, and to identify the kinds of samples that would be most likely to carry the key information. […]

A robotic rover deployed in the most Mars-like environment on Earth, the Atacama Desert in Chile, has successfully recovered subsurface soil samples during a trial mission to find signs of life. The samples contained unusual and highly specialized microbes that were distributed in patches, which was linked to the scarce availability of water and nutrients. These findings will aid the search for evidence of signs of life during future planned missions to Mars. […]

One of the most successful and enduring feats of interplanetary exploration, NASA's Opportunity rover mission is at an end after almost 15 years exploring the surface of Mars and helping lay the groundwork for NASA's return to the Red Planet. […]

Curious surface features, water-formed minerals, 3-D stereo views, and even a sighting of the InSight lander showcase the impressive range of imaging capabilities of the ExoMars Trace Gas Orbiter. […]

In his new book, Assembling Life, David Deamer challenges the consensus that life began in the ocean and presents an alternative scenario, based on his research, in which life began in freshwater hot springs. […]

NASA's first rover mission to Mars, the Pathfinder, imaged an extraterrestrial marine spillover landscape 22 years ago, according to a new paper by Planetary Science Institute Senior Scientist Alexis Rodriguez. […]

Returning to Earth from the International Space Station, Canadian astronaut Chris Hadfield remarked how making the right decision is vital in high pressure environments, saying: "Most of the time, you only really get one try to do most of the critical stuff and the consequences are life or death." […]

A little piece of technology is making a big splash in Australia's space industry. So what on (and off) Earth is a CubeSat? […]
