Scientists in 2018 had thought they were looking at liquid water when they saw bright radar reflections under the polar cap. However, the new study published Ja...
How to Retain a Core
Jan 25, 2022 (JPL)
As we drill, the bit teeth cut a 27mm diameter circle in the rock and leave the 13mm diameter center intact. As we dig deeper, that cylinder of rock is fed into...
New control technique uses solar panels to reach desired Mars orbit
Jan 25, 2022 (SPX)

Ejecting Mars' Pebbles
Jan 22, 2022 (JPL)
Pebbles in Bit Carousel On Monday, Jan. 17, the WATSON camera imaged the bit carousel and its pebbles - and also took images underneath the rover to establish j...
Sols 3364-3366: Back at the Prow
Jan 22, 2022 (SPX)
In today's plan, we'll collect lots of remote sensing data of the Prow from our standoff location. We're taking two ChemCam RMI mosaics of the area on targets n...
Consistent asteroid showers rock previous thinking on Mars craters
Jan 22, 2022 (SPX)
The study, published in Earth and Planetary Science Letters, analysed the formation of more than 500 large Martian craters using a crater detection algorithm pr...
Sols 3362-3363: Sedimentologist's Delight
Jan 21, 2022 (JPL)
Yesterday there was a small rock under the right rear rover wheel, so we had to kick that rock to the curb to get into a stable position for using the rover arm...
Perseverance's first year on Mars: Purdue professor, mission team member looks at what is ahead
Jan 21, 2022 (SPX)
Feb. 18 will mark one year since the rover landed on the red planet following a seven-month, 300-million-mile flight across space. Horgan, associate professor o...
Sol 3361: Keeping the Dog Leashed
Jan 20, 2022 (SPX)
During a dog's eye sequence, the rover's arm walks the MAHLI camera along a feature near ground level, just how your martian canine (obviously named "Rover") wo...
Grounded: First Flight Delay Due to Inclement Weather on Another World
Jan 20, 2022 (JPL)
With 18 flights completed to date, weather forecasting has become an integral piece of Martian flight planning. Since the first flight on April 19, 2021, Jezero...
Sols 3357-3360: Edging Closer and Closer to Panari
Jan 19, 2022 (JPL)
In our last plan, we edged towards the inclined rock in the front right corner of the image, ending on some flatter rock a safe distance back. This end of drive...
Curiosity measures intriguing carbon signature on Mars
Jan 18, 2022 (SPX)
While the finding is intriguing, it doesn't necessarily point to ancient life on Mars, as scientists have not yet found conclusive supporting evidence of ancien...
Newly discovered carbon may yield clues to ancient Mars
Jan 18, 2022 (SPX)

Steady driving towards ExoMars launch
Jan 18, 2022 (ESA)
ESA's Rosalind Franklin rover starts the year with months of successful maintenance and functional tests behind it. All its instruments are go for flight, with ...
Rolling stones on Mars
Jan 14, 2022 (ESA)
The image was taken by the CaSSIS camera onboard the ESA/Roscosmos ExoMars Trace Gas Orbiter on 3 August 2020, and captures a slice through the maze-like system...
Martian Meteorite's organic materials origin not biological
Jan 14, 2022 (SPX)
The meteorite, called Allan Hills (ALH) 84001, was discovered in the Antarctic in 1984 and is considered one of the oldest known projectiles to reach Earth from...
Sols 3355-2256: Closer to the Prow
Jan 14, 2022 (JPL)

Pebbles before mountains
Jan 14, 2022 (JPL)
With terrestrial experimentation complete, we have begun executing our mitigation strategy on Mars. On Jan. 12 we did a detailed image survey of the ground belo...
Sol 3354: Tantalizingly Out of Reach
Jan 13, 2022 (JPL)
We, the rover planners, were busy today despite the plan looking deceptively simple. The face of "the Prow" itself is just a bit out of reach, so instead we are...
