Despite Doubts from Quantum Physicists: Einstein's Theory of Relativity Reaffirmed

One of the most basic assumptions of fundamental physics is that the different properties of mass -- weight, inertia and gravitation -- always remain the same in relation to each other. Although all measurements to date confirm the equivalence ...

New Study Reveals Evidence of Diverse Organic Material on Mars

Scientists gain vital insights into Mars' history and potential for supporting ...

Training Robots How to Learn, Make Decisions on the Fly

Mars rovers have teams of human experts on Earth telling them what to do. But robots on lander missions to moons orbiting Saturn or Jupiter are too far away to receive timely commands from Earth. Researchers developed a novel learning-based method so robots on extraterrestrial bodies can make ...

Gauging the Strength of Ancient and Active Rivers Beyond Earth

A new technique allows scientists to see how intensely rivers used to flow on Mars, and how they currently flow on Titan. The method uses satellite observations to estimate the rate at which rivers move fluid and sediment ...

Better Tools Needed to Determine Ancient Life on Mars

Current state-of-the-art instrumentation being sent to Mars to collect and analyze evidence of life might not be sensitive enough to make accurate assessments, according to new ...

Study Quantifies Global Impact of Electricity in Dust Storms on Mars

Mars is infamous for its intense dust storms, some of which kick up enough dust to be seen by telescopes on Earth. When dust particles rub against each other, as they do in Martian dust storms, they ...

Hubble Captures the Start of a New Spoke Season at Saturn

Since their discovery by NASA's Voyager mission in the 1980s, temporary 'spoke' features across Saturn's rings have fascinated scientists, yet eluded explanation. They have been ...

Spanish Lagoon Used to Better Understand Wet-to-Dry Transition of Mars

In the ongoing search for signs of life on Mars, a new study proposes focusing on 'time-resolved analogs' -- dynamic and similar Earth environments where changes can be analyzed over many ...

Researchers Complete First Real-World Study of Martian Helicopter Dust Dynamics

Researchers have completed the first real-world study of Martian dust dynamics based on Ingenuity's historic first flights on the Red Planet, paving the way for future extraterrestrial ...

The Rich Meteorology of Mars Studied in Detail from the Perseverance Rover

Perseverance has now completed its investigation of the atmosphere throughout the first Martian year (which lasts approximately two Earth years). Specifically, astronomers have studied seasonal and ...
