Pasadena, CA – On April 28th, a supermagnetized stellar remnant known as a magnetar blasted out a simultaneous mix of X-ray and radio signals never observed before. The flare-up included the first fast radio burst (FRB) ever seen from within our Milky Way galaxy and shows that magnetars can produce these mysterious and powerful radio blasts previously only seen in other galaxies.
“Before this event, a wide variety of scenarios could explain the origin of FRBs,” said Chris Bochenek, a doctoral student in astrophysics at Caltech who led one study of the radio event.

Pasadena, CA – Scientists working with NASA’s Curiosity Mars rover have been excited to explore a region called “the clay-bearing unit” since before the spacecraft launched. Now, the rover has finally tasted its first sample from this part of Mount Sharp. Curiosity drilled a piece of bedrock nicknamed “Aberlady” on Saturday, April 6th, 2019 (the 2,370th Martian day, or sol, of the mission), and delivered the sample to its internal mineralogy lab on Wednesday, April 10th (Sol 2374).
The rover’s drill chewed easily through the rock, unlike some of the tougher targets it faced nearby on Vera Rubin Ridge.

Pasadena, CA – NASA has a new mission to Mars, and it’s taking podcast listeners along for the ride.
Launched Monday, October 29th, 2018 the eight-episode series “On a Mission” follows the InSight lander as it travels hundreds of millions of miles and attempts to land on Mars on November 26th.
“On a Mission” will be the first JPL podcast to track a mission during flight, through interviews with the InSight team at NASA’s Jet Propulsion Laboratory in Pasadena, California.

Washington, D.C. – The engineers and scientists working on NASA’s Juno mission have been busying themselves, getting their newly arrived Jupiter orbiter ready for operations around the largest planetary inhabitant in the solar system.
Juno successfully entered Jupiter’s orbit during a 35-minute engine burn on Monday, July 4th. Confirmation that the burn had completed was received on Earth at 8:53pm. PDT (11:53pm EDT) that evening.

Pasadena, CA – When NASA’s Juno mission arrives at Jupiter on July 4th, 2016, new views of the giant planet’s swirling clouds will be sent back to Earth, courtesy of its color camera, called JunoCam. But unlike previous space missions, professional scientists will not be the ones producing the processed views, or even choosing which images to capture.
Instead, the public will act as a virtual imaging team, participating in key steps of the process, from identifying features of interest to sharing the finished images online.
“This is really the public’s camera. We are hoping students and whole classrooms will get involved and join our team,” said Scott Bolton, Juno principal investigator at the Southwest Research Institute in San Antonio.

Washington, D.C. – Earth’s oceans and land cover are doing us a favor. As people burn fossil fuels and clear forests, only half of the carbon dioxide released stays in the atmosphere, warming and altering Earth’s climate. The other half is removed from the air by the planet’s vegetation ecosystems and oceans.
As carbon dioxide levels in the atmosphere continue their rapid, human-made rise past levels not seen for hundreds of thousands of years, NASA scientists and others are confronted with an important question for the future of our planet: How long can this balancing act continue? And if forests, other vegetation and the ocean cannot continue to absorb as much or more of our carbon emissions, what does that mean for the pace of climate change in the coming century?

Pasadena, CA – Seas around the world have risen an average of nearly 3 inches (8 centimeters) since 1992, with some locations rising more than 9 inches (25 centimeters) due to natural variation, according to the latest satellite measurements from NASA and its partners.
An intensive research effort now underway, aided by NASA observations and analysis, points to an unavoidable rise of several feet in the future.
The question scientists are grappling with is how quickly will seas rise?

Pasadena, CA – As Californians continue pumping groundwater in response to the historic drought, the California Department of Water Resources today released a new NASA report showing land in the San Joaquin Valley is sinking faster than ever before, nearly 2 inches (5 centimeters) per month in some locations.
“Because of increased pumping, groundwater levels are reaching record lows — up to 100 feet (30 meters) lower than previous records,” said Department of Water Resources Director Mark Cowin. “As extensive groundwater pumping continues, the land is sinking more rapidly and this puts nearby infrastructure at greater risk of costly damage.”

Pasadena, CA – NASA’s Cassini spacecraft will zip past Saturn’s moon Dione on Monday, August 17th — the final close flyby of this icy satellite during the spacecraft’s long mission.
Cassini’s closest approach, within 295 miles (474 kilometers) of Dione’s surface, will occur at 11:33am PDT (2:33pm EDT). Mission controllers expect fresh images to begin arriving on Earth within a couple of days following the encounter.
Cassini scientists have a bevy of investigations planned for Dione. Gravity-science data from the flyby will improve scientists’ knowledge of the moon’s internal structure and allow comparisons to Saturn’s other moons.

Pasadena, CA – Our Milky Way galaxy is littered with the still-sizzling remains of exploded stars.
When the most massive stars explode as supernovas, they don’t fade into the night, but sometimes glow ferociously with high-energy gamma rays. What powers these energetic stellar remains?
NASA’s Nuclear Spectroscopic Telescope Array, or NuSTAR, is helping to untangle the mystery. The observatory’s high-energy X-ray eyes were able to peer into a particular site of powerful gamma rays and confirm the source: A spinning, dead star called a pulsar.
