Evidence collected by the Tianwen 1 orbiter and Zhurong rover supports the possible existence of an ancient ocean in the Utopia Planitia region of Mars.

You have to look for the clues that the protoplanet exists, not for the protoplanet itself.

Making things for Mars astronauts on-planet would be a boon for future human missions.

Using its DRACO camera, DART has imaged the asteroid Didymos and its moonlet Dimorphos.

This is the spacecraft's 13th close approach to the sun, but its first in a new era of solar activity.

Think of the MOXIE instrument as a small tree, breathing carbon dioxide in and oxygen out.

A recent survey of planetary defense experts reveals concern about the growing number of artificial satellites in low Earth orbit.

A robotic spacecraft will crash into the asteroid Dimorphos in an attempt to alter its trajectory.

Dr. Lori Glaze of NASA's Planetary Science Division offered updates about the potential mission at a virtual town hall.

Researchers used computer models to estimate the rocket's acoustic levels, determining they were not high enough to cause such damage.

Impressive infrared images of Jupiter's auroras were processed by citizen scientist Judy Schmidt.

Scientists hope CuSP will pave the way for a network of weather stations in interplanetary space.

For practically all of human existence, we've been fascinated by our closest celestial neighbor, incorporating it into myth, fantasy and scientific research.

Exoplanet images might be contaminated by the light from their neighbors, a new study suggests, but scientists are learning how to remove the effects of these photobombers.

The OMOTENASHI mission is the only secondary payload on Artemis 1 that will have a controlled landing on the surface of the moon.

NASA's coming megarocket launch isn't just going to the moon, it's going far beyond that — some of its secondary payloads far, far beyond.

Scientists will study the effects of radiation on yeast in preparation for long-duration crewed missions to deep space.

Scientists studied the trajectory and debris field of asteroid 2008 TC3 to determine which specific parts of the space rock made it down to the Earth's surface.

Students at the Delft University of Technology (TU Delft) in the Netherlands are developing the world's smallest and lightest moon rover, called Lunar Zebro.

The Lunar IceCube and Lunar Polar Hydrogen Mapper (LunaH-Map) missions will search the moon for water using two different techniques.

A prototype of the lunar rover demonstrated its capabilities in navigating the moon's challenging terrain.

NASA's Aqua satellite photographed plumes of dust being drawn from Africa's Sahara Desert and sent across the Atlantic towards the United States and the Caribbean.

The Hubble Space Telescope has imaged globular cluster NGC 6638, located in the constellation Sagittarius.

As the Mars rover traverses the planet, it's come across pieces of its entry, landing, and descent hardware.

Curiosity landed on Mars on Aug. 5, 2012, with one main goal: to determine whether the planet was once habitable. In 10 years, it has answered that question and many others.
