Celebrating NASA’s Mars Reconnaissance Orbiter’s 20th Anniversary: Crater Near Sirenum Fossae

NASA’s Mars Reconnaissance Orbiter (MRO) captures a detailed view of a relatively fresh crater in this image released on June 3, 2015. The crater has a sharp rim and well-preserved ejecta. The steep inner slopes are carved by gullies and include possible recurring slope lineae on the equator-facing slopes. This crater is monitored for changes […]

NASA’s ESCAPADE Ready to Study Space Weather from Earth to Mars

Mars is not what it used to be. Once warm, watery, and blanketed by a thick atmosphere, today the Red Planet is cold, dry, and draped by a thin atmospheric veil. The main culprit is a relentless stream of particles from the Sun, known as the solar wind. Over billions of years, the solar wind has stripped away […]

NASA’s Curiosity Rover Sees Martian ‘Spiderwebs’ Up Close

For about six months, NASA’s Curiosity Mars rover has been exploring a region full of geologic formations called boxwork, low ridges standing roughly 3 to 6 feet (1 to 2 meters) tall with sandy hollows in between. Crisscrossing the surface for miles, the formations suggest ancient groundwater flowed on this part of the Red Planet […]

Curiosity Sends Holiday Postcard from Mars

Team members working with NASA’s Curiosity Mars rover created this “postcard” by commanding the rover to take images at two times of day on Nov. 18, 2025, spanning periods that occurred on both the 4,722nd and 4,723rd Martian days, or sols, of the mission. The panoramas were captured at 4:15 p.m. on Sol 4,722 and […]

NASA’s Perseverance Mars Rover Ready to Roll for Miles in Years Ahead

After nearly five years on Mars, NASA’s Perseverance rover has traveled almost 25 miles (40 kilometers), and the mission team has been busy testing the rover’s durability and gathering new science findings on the way to a new region nicknamed “Lac de Charmes,” where it will be searching for rocks to sample in the coming […]

NASA Rover Detects Electric Sparks in Mars Dust Devils, Storms

Perseverance confirmed a long-suspected phenomenon in which electrical discharges and their associated shock waves can be born within Red Planet mini-twisters. NASA’s Perseverance Mars rover has recorded the sounds of electrical discharges —sparks — and mini-sonic booms in dust devils on Mars.

NASA Tests Drones in Death Valley, Preps for Martian Sands and Skies

Next-generation drone flight software is just one of 25 technologies for the Red Planet that the space agency funded for development this year. When NASA engineers want to test a concept for exploring the Red Planet, they have to find ways to create Mars-like conditions here on Earth. Then they test, tinker, and repeat.  That’s […]

NASA Orbiter Shines New Light on Long-Running Martian Mystery

Results from an enhanced radar technique have demonstrated improvement to sub-surface observations of Mars.  NASA’s Mars Reconnaissance Orbiter (MRO) has revisited and raised new questions about a mysterious feature buried beneath thousands of feet of ice at the Red Planet’s south pole.

NASA’s Mars Spacecraft Capture Images of Comet 3I/ATLAS

Two orbiters and a rover captured images of the interstellar object — from the closest location any of the agency’s spacecraft may get — that could reveal new details. At the start of October, three of NASA’s Mars spacecraft had front row seats to view 3I/ATLAS, only the third interstellar object so far discovered in […]

This article was updated to include the full range of dates from the SOHO image. Lee esta historia en español aquí. NASA is in the midst of an unprecedented solar system-wide observation campaign, turning its spacecraft and space telescopes to follow comet 3I/ATLAS, the third known interstellar object to pass through our solar system. Twelve […]
