Pasadena, CA – Where did life first form on Earth? Some scientists think it could have been around hydrothermal vents that may have existed at the bottom of the ocean 4.5 billion years ago.
In a new paper in the journal Astrobiology, NASA scientists at the Jet Propulsion Laboratory describe how they mimicked possible ancient undersea environments with a complex experimental setup.
They showed that under extreme pressure, fluid from these ancient seafloor cracks mixed with ocean water could have reacted with minerals from the hydrothermal vents to produce organic molecules – the building blocks that compose nearly all life on Earth.
Pasadena, CA – Eight and a half years into its grand tour of the solar system, NASA’s Voyager 2 spacecraft was ready for another encounter. It was January 24th, 1986, and soon it would meet the mysterious seventh planet, icy-cold Uranus.
Over the next few hours, Voyager 2 flew within 50,600 miles (81,433 kilometers) of Uranus’ cloud tops, collecting data that revealed two new rings, 11 new moons and temperatures below minus 353 degrees Fahrenheit (minus 214 degrees Celsius). The dataset is still the only up-close measurements we have ever made of the planet.
Washington, D.C. – NASA’s Spitzer Space Telescope’s mission has come to an end after more than 16 years studying the universe in infrared light, revealing new wonders in our solar system, our galaxy and beyond.
Mission engineers confirmed at about 2:30pm PT (4:30pm CT) Thursday the spacecraft was placed in safe mode, ceasing all science operations. After the decommissioning was confirmed, Spitzer Project Manager Joseph Hunt declared the mission had officially ended.
Washington, D.C. – In 2019, NASA celebrated the 50th anniversary of the agency’s Apollo 11 Moon landing, the most historic moment in space exploration, while also making significant progress toward putting the first woman and next man on the Moon by 2024 under the Artemis program.
Through America’s Moon to Mars exploration approach, Artemis gained bipartisan support this year among members of Congress, the U.S aerospace industry, as well as with international partners, including Canada, Australia, and Japan, and member states of the European Space Agency.
Pasadena, CA – NASA’s little robotic explorer will be rolling into Antarctica this month to perform a gymnastic feat – driving upside down under sea ice.
BRUIE, or the Buoyant Rover for Under-Ice Exploration, is being developed for underwater exploration in extraterrestrial, icy waters by engineers at NASA’s Jet Propulsion Laboratory in Pasadena, California. It will spend the next month testing its endurance at Australia’s Casey research station in Antarctica, in preparation for a mission that could one day search for life in ocean worlds beyond Earth.
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 – New kinds of organic compounds, the ingredients of amino acids, have been detected in the plumes bursting from Saturn’s moon Enceladus. The findings are the result of the ongoing deep dive into data from NASA’s Cassini mission.
Powerful hydrothermal vents eject material from Enceladus’ core, which mixes with water from the moon’s massive subsurface ocean before it is released into space as water vapor and ice grains. The newly discovered molecules, condensed onto the ice grains, were determined to be nitrogen- and oxygen-bearing compounds.
Pasadena, CA – NASA mini robots that can roll, fly, float and swim, then morph into a single machine? Together they form Shapeshifter, a developing concept for a transformational vehicle to explore treacherous, distant worlds.
In a dusty robotics yard at NASA’s Jet Propulsion Laboratory in Pasadena, California, the Shapeshifter team is testing a 3D-printed prototype of this unusual explorer. A contraption that looks like a drone encased in an elongated hamster wheel rolls across the yard, then splits in half.
Pasadena, CA – NASA’s Cassini spacecraft radar data recently published research presents a new scenario to explain why some methane-filled lakes on Saturn’s moon Titan are surrounded by steep rims that reach hundreds of feet high. The models suggests that explosions of warming nitrogen created basins in the moon’s crust.

Pasadena, CA -NASA’s Jet Propulsion Laboratory engineers in Pasadena, California, have designed a four-limbed robot named LEMUR (Limbed Excursion Mechanical Utility Robot) can scale rock walls, gripping with hundreds of tiny fishhooks in each of its 16 fingers and using artificial intelligence (AI) to find its way around obstacles.
In its last field test in Death Valley, California, in early 2019, LEMUR chose a route up a cliff while scanning the rock for ancient fossils from the sea that once filled the area.
