The study is based on analysis of sample spacesuit materials that were placed on the rover to help prepare for future exploration. Learn more:
We’ve known since the Apollo missions that dust can present challenges for explorers on other worlds.
Now, scientists are using instruments on the Perseverance rover to understand the risks of dust on Mars and find clues about how to protect future crews on the Red Planet. ½

On Oct. 24, 2001, NASA's Mars Odyssey spacecraft slipped into orbit around the Red Planet.
25 years later, it's still conducting science and relaying messages from the rovers, making it the longest-operating orbiter ever at a planet beyond Earth. ½

The MMX spacecraft carries two pieces of NASA hardware: The MEGANE instrument will be key to revealing the origin of Mars’s moons by measuring their elemental composition.
The P-Sampler demonstration will advance capabilities for surface material acquisition in low gravity. ½

Perseverance has set a new off-world record! 🏅
On Oct. 11, the rover's odometer hit 28.10 miles (45.22 kilometers), eclipsing the distance record set by NASA's Opportunity rover. 1/2

Media are invited to join NASA for a teleconference at 4 p.m. EDT, Thursday, Oct. 15, to preview the agency’s contributions to @JAXA_en's Martian Moons eXploration (MMX) mission, which will explore the Red Planet's moons and return a sample of Phobos.

Layered beauty 😍
The Arabia Terra region on Mars has deposits that preserve a record of the planet’s ancient climate. The rhythmic nature of the layers could be due to cyclic processes, such as dust storms, perhaps involving groundwater. 1/2

Sometimes following the water can lead to surprising places💧
A new study of data from Perseverance reveals that rocks in Jezero Crater were shaped by a complex sequence of ancient lakes, groundwater systems, and hydrothermal fluids. 1/2

Sunrise, sunset 🏜️
To mark Curiosity’s 5,000th Martian day on the Red Planet, the rover’s team created this postcard. It combines two panoramas, with blue colors representing images taken in the morning, and yellow colors for the images taken at dusk. 1/2

The Curiosity rover has now been exploring the surface of Mars for more than 5000 Martian days! Each day on Mars, or "sol," is about 24.6 hours long.
How did Curiosity and its team mark the occasion? By working, of course. 1/2

On Earth, solar eclipses happen when the Moon passes in front of the Sun as seen from the ground. On Mars, sometimes one of its moons does the same thing…but they’re too small to fully cover the Sun’s disc. Perseverance captured this look at Phobos transiting the Sun in 2024.

SkyFall is already taking flight, at least in the lab.
In its 14 years on Mars, the Curiosity rover has taken more than 700,000 images, but this one is special – because it was one of the first.
Happy landiversary, Curiosity!
We're taking your questions now!
Our spacecraft have been on the surface and in the skies of Mars for more than 50 years. What would you ask NASA Mars scientists about the past, present, and future of exploration?
Join us on Wednesday, Aug. 5, from 11:00am-12:30pm PT for a @Reddit AMA:

Curiosity has delivered a new 360-degree panorama from Mars. “We’ve seen a lot of fascinating landscapes through Curiosity’s eyes, but this sea of polygons took our breath away,” said the mission’s project scientist. 1/2

NASA has given approval to begin implementing its project to support @ESA's Rosalind Franklin mission. Scheduled to launch in 2028, this Mars rover will be the first to search for signs of past or present life under the Red Planet’s surface.
