Washington, D.C. – As part of the Artemis program, NASA is planning to send its first mobile robot to the Moon in late 2023 in search of ice and other resources on and below the lunar surface.
Data from the Volatiles Investigating Polar Exploration Rover, or VIPER, would help the agency map resources at the lunar South Pole that could one day be harvested for long-term human exploration at the Moon.
Washington, D.C. – NASA’s new water-hunting mission to the Moon, the Volatiles Investigating Polar Exploration Rover, or VIPER, has received agency-level approval to move from formulation into implementation of the final design of the rover. This puts the mission one step closer to launching to the Moon’s South Pole in late 2023.
The decision follows VIPER passing the important preliminary design review milestone in August, in which the mission successfully demonstrated to NASA’s Planetary Science Division and the independent VIPER review team that it can meet all the requirements with an acceptable level of risk within cost and schedule restraints.
Pasadena, CA – Scientists have used data from NASA’s Cassini mission to delve into the impact craters on the surface of Titan, revealing more detail than ever before about how the craters evolve and how weather drives changes on the surface of Saturn’s mammoth moon.
Like Earth, Titan has a thick atmosphere that acts as a protective shield from meteoroids; meanwhile, erosion and other geologic processes efficiently erase craters made by meteoroids that do reach the surface. The result is far fewer impacts and craters than on other moons. Even so, because impacts stir up what lies beneath and expose it, Titan’s impact craters reveal a lot.
Pasadena, CA – Since leaving Earth 15 years ago, NASA’s Mars Reconnaissance Orbiter has reshaped our understanding of the Red Planet. The veteran spacecraft studies temperatures in Mars’ thin atmosphere, peers underground with radar, and detects minerals on the planet’s surface. But perhaps what it’s become best known for are stunning images.
Among its instruments, MRO carries three cameras: The Mars Color Imager (MARCI) has a fisheye lens that produces a daily global view. The Context Camera (CTX) provides 19-mile-wide (30-kilometer-wide) black-and-white terrain shots.
NASA’s Lunar Reconnaissance Orbiter (LRO) spacecraft radar shows the Moon may be Richer in Metals than thought
Greenbelt, MD – What started out as a hunt for ice lurking in polar lunar craters turned into an unexpected finding that could help clear some muddy history about the Moon’s formation.
Team members of the Miniature Radio Frequency (Mini-RF) instrument on NASA’s Lunar Reconnaissance Orbiter (LRO) spacecraft found new evidence that the Moon’s subsurface might be richer in metals, like iron and titanium, than researchers thought. That finding, published July 1st in Earth and Planetary Science Letters, could aid in drawing a clearer connection between Earth and the Moon.
Washington, D.C. – NASA has released the first map showing the global geology of Saturn’s largest moon, Titan, has been completed and fully reveals a dynamic world of dunes, lakes, plains, craters and other terrains.
Titan is the only planetary body in our solar system other than Earth known to have stable liquid on its surface. But instead of water raining down from clouds and filling lakes and seas as on Earth, on Titan what rains down is methane and ethane – hydrocarbons that we think of as gases but that behave as liquids in Titan’s frigid climate.
Pasadena, CA – NASA says the Earth’s Moon formed vast basins called “mare” (pronounced MAR-ay) over a billions of years ago. Scientists have long assumed these basins were dead, still places where the last geologic activity occurred long before dinosaurs roamed Earth.
But a survey of more than 12,000 images reveals that at least one lunar mare has been cracking and shifting as much as other parts of the Moon – and may even be doing so today. The study adds to a growing understanding that the Moon is an actively changing world.
Washington, D.C. – 1. Why Asteroids Impact Earth: Why do asteroids and meteoroids collide with Earth?
NASA says these objects orbit the Sun just like the planets, as they have been doing for billions of years, but small effects such as gravitational nudges from the planets can jostle the orbits, making them gradually shift over million-year timescales or abruptly reposition if there is a close planetary encounter.

Pasadena, CA – NASA’s Dawn mission is drawing to a close after 11 years of breaking new ground in planetary science, gathering breathtaking imagery, and performing unprecedented feats of spacecraft engineering.
Dawn’s mission was extended several times, outperforming scientists’ expectations in its exploration of two planet-like bodies, Ceres and Vesta, that make up 45 percent of the mass of the main asteroid belt. Now the spacecraft is about to run out of a key fuel, hydrazine. When that happens, most likely between mid-September and mid-October, Dawn will lose its ability to communicate with Earth. It will remain in a silent orbit around Ceres for decades.
NASA’s Jet Propulsion Laboratory
Pasadena, CA – The study of exoplanets — planets that lie outside our solar system — could help scientists answer big questions about our place in the universe, and whether life exists beyond Earth.
But, these distant worlds are extremely faint and difficult to image directly. A new study uses Earth as a stand-in for an exoplanet, and shows that even with very little light — as little as one pixel — it is still possible to measure key characteristics of distant worlds.
