DARPA pursues tactical-grade clock that maintains precision over time
by Staff Writers
Washington DC (SPX) May 18, 2022
Mission success can come down to mere millionths or billionths of a second and current military systems that rely on global positioning system (GPS) timing updates are inherently vulnerable. Though GPS is a revolutionary capability, it is unreliable underground or underwater and can be degraded or unavailable due to adversarial signal jamming.

Seeing through the fog-pinpointing young stars and their protoplanetary disks
Boston MA (SPX) May 18, 2022
Imagine walking through a dense, hazy fog in the middle of the night, seeing patches of light from cars and towns shimmering in the distance. It's nearly impossible to tell if the lights are deep in the fog or beyond it. Astronomers trying to find young stars face a similar problem: the light from stars they're hunting is shimmering through great big regions of hazy gas and dust in space, called

Mars' emitted energy and seasonal energy imbalance
Houston TX (SPX) May 18, 2022
A seasonal imbalance in the amount of solar energy absorbed and released by the planet Mars is a likely cause of the dust storms that have long intrigued observers, a team of researchers reports.
Mars' extreme imbalance in energy budget (a term referring to the measurement of solar energy a planet takes in from the sun then releases as heat) was documented by University of Houston research

A SAM Methane Experiment Between Drives Sols 3476-3477
Pasadena CA (JPL) May 18, 2022
Curiosity continues to navigate challenging terrain. The drive executed over the weekend moved us 8 m from our previous location. Prior to the weekend drive, we completed contact science with APXS and MAHLI on targets "Pedra Pintada" and "San Pedro," the latter of which was brushed with the Dust Removal Tool (DRT) to remove thin airfall dust that was coating the surface of the rock face.

Rocket engine exhaust pollution extends high into Earth's atmosphere
Washington DC (SPX) May 18, 2022
Reusable space technology has led to a rise in space transportation at a lower cost, as popularized by commercial spaceflights of companies like SpaceX and Virgin Galactic. What is poorly understood, however, is rockets' propulsion emissions creating significant heating and compositional changes in the atmosphere.
In Physics of Fluids, by AIP Publishing, researchers from the University of

NASA Seeks Input on Moon to Mars Objectives, Comments Due May 31
Washington DC (SPX) May 18, 2022
As NASA moves forward with plans to send astronauts to the Moon under Artemis missions to prepare for human exploration of Mars, the agency is calling on U.S. industry, academia, international communities, and other stakeholders to provide input on its deep space exploration objectives.
NASA released a draft set of high-level objectives Tuesday, May 17, identifying 50 points falling under

Astronauts may one day drink water from ancient moon volcanoes
Boulder CO (SPX) May 18, 2022
Billions of years ago, a series of volcanic eruptions broke loose on the moon, blanketing hundreds of thousands of square miles of the orb's surface in hot lava. Over the eons, that lava created the dark blotches, or maria, that give the face of the moon its familiar appearance today.
Now, new research from CU Boulder suggests that volcanoes may have left another lasting impact on the luna

NASA's InSight still hunting marsquakes as power levels diminish
Dusty solar panels and darker skies are expected to bring the Mars lander mission to a close around the end of this year.
NASA's InSight Mars lander is gradually losing power and is anticipated to end science operations later this summer. By December, InSight's team expects the lander to have become inoperative, concluding a mission that has thus far detected more than 1,300 marsquakes—most recently, a magnitude 5 that occurred on May 4—and located quake-prone regions of the Red Planet.
The information gathered from those quakes has allowed scientists to measure the depth and composition of Mars' crust, mantle, and core. Additionally, InSight (short for Interior Exploration using Seismic Investigations, Geodesy and Heat Transport) has recorded invaluable weather data and studied remnants of Mars' ancient magnetic field.
