NASA Jet Propulsion Laboratory manages many of NASA's robotic missions exploring Earth, the solar system and our universe. Tweets from JPL's News Office.
Key insights into ice loss in Greenland and Antarctica, two regions that hold over 90% of Earth’s ice, have been provided by 20 years of GRACE + GRACE-FO @NASAEarth satellite data. Melting at the poles is a leading cause of sea-level rise.
One step closer to launch @NasaPersevere’s sample handling system is in! The system will help collect core samples of Martian rock and soil. With less than four months until take-off, the rover reaches significant pre-launch milestones almost daily.
Ah, the red outdoors... @MarsCuriosity took this selfie before a record climb to the top rock layer known as “Greenheugh Pediment.” The panorama is made up of 86 individual images. How does the rover take selfies? Check this out:
Antarctica's Denman Glacier, which is melting from the bottom up, is especially vulnerable to climate impacts. The shape of the ground under it makes it particularly prone to warm water. If all of Denman melted, seas would rise ~4.9 ft (1.5 m) worldwide.
Scientists revisit decades-old @NASAVoyager 2 data and find one more secret: Uranus appears to be losing some of its atmosphere to space. A “plasmoid” in the planet's one-of-a-kind magnetic environment may be the cause. More about the discovery:

All aboard, @NasaPersevere ! Essays from @NASA 's “Name the Rover” contest, along with 10.9+ million names you sent in through the “Send Your Name to Mars” campaign, were stenciled on three chips. They’re now secured to the 2,300-pound rover. Take a look:
Up for an out-of-the-box challenge? @NASA needs help developing the world’s first sensor to detect obstacles in a rover’s path while withstanding Venus’ hellish temperatures and crushing surface pressure. Submissions due May 29:
The most ambitious crossover announcement in space? @NASAInSight just named @RollingStones Rock" on Mars in honor of the band. Watch @RobertDowneyJr announce the @NASA news live on stage at the Rose Bowl ahead of tonight's concert. #MarsRocks
The wise old Moon shows its age After billions of years of cooling, the Moon continues to shrink. This @NASA study shows how wrinkle ridges, curved hills and shallow trenches are forming as the Moon loses heat:
